Eggs, half and half, Dijon mustard, pie crust, cheddar Monterey Jack cheese, ham, sun-dried tomatoes, green onions.

I have a real soft spot for recipes that make me look more organized than I actually am. You know the ones? They come out of the oven looking brunch-table ready, but secretly they started with store-bought pie crust and a very casual “let’s just see what happens” attitude. This Sheet Pan Quiche is exactly that kind of recipe.

It has all the cozy things I love about quiche: creamy eggs, melty cheese, savory ham, a flaky crust, and little pops of flavor from sun-dried tomatoes and green onions. But instead of baking it in a round pie dish and hoping the slices behave, you make it in a sheet pan and cut it into small, shareable pieces. Honestly, that alone makes me breathe a little easier.

This Sheet Pan Quiche works beautifully as a warm breakfast or brunch, but it also has a second personality. Chill it for at least 3 hours, slice it into little cubes, and suddenly you’ve got an appetizer. Isn’t that handy? I love a recipe that can go from “family brunch” to “party platter” without needing a costume change.

And let’s talk about the store-bought crust for a second. I know homemade crust is lovely. Truly. But some days, I do not have the emotional energy to make pastry from scratch. Some days I want quiche without turning the counter into a flour-covered crime scene. Sound familiar? This recipe gives you that buttery crust feeling without the fuss, and I’m very grateful for it.

The filling is simple but not boring. The ham makes it hearty, the cheese makes it rich, the Dijon mustard gives the eggs a tiny bit of tang, and the sun-dried tomatoes bring this sweet-savory brightness that makes the whole pan feel a little more special. Not fancy in a stiff way. More like, oh, this tastes like I tried.

This easy sheet pan quiche makes about 32 pieces, which is great for brunches, potlucks, baby showers, holiday mornings, or those family gatherings where people say they’re “just nibbling” and somehow keep coming back to the tray. I mean, I get it. Small pieces are dangerous. They make everyone believe they’re being reasonable.

I started making Sheet Pan Quiche because traditional quiche, while delicious, can sometimes feel a little too delicate for real-life hosting. I love a pretty round quiche as much as anyone, but when people are coming over and the kitchen already looks like a tiny storm passed through, I don’t always want to worry about perfect wedges and decorative crust edges. Sometimes I want something I can bake, slice, and serve without holding my breath.

The first time I made this sheet pan breakfast quiche, I was hosting a casual brunch and had fully convinced myself that I was going to be calm. I had a plan. I had coffee. I had even wiped the counter, which always makes me feel like a responsible adult for about eight minutes. Then people arrived early, someone needed a spoon, someone else asked if the coffee was decaf, and I realized I still hadn’t whisked the eggs. So, you know, normal brunch chaos.

That’s when this recipe really came through. I sprayed the pan, rolled out the pie crust a little, trimmed the round edges, and patched the corners like I was fixing a tiny edible quilt. It wasn’t perfect. One corner looked a little questionable. But once I scattered on the ham, cheese, sun-dried tomatoes, and green onions, then poured the egg mixture over everything, it all started looking like I had planned it that way from the beginning. A small kitchen miracle.

When the Sheet Pan Quiche came out of the oven, the center was puffed, the edges were golden, and the whole kitchen smelled like brunch had officially arrived. There was that warm egg-and-cheese smell, with a little ham and tomato sweetness in the background. I remember feeling weirdly proud of it. Not because it was complicated, but because it was so practical and still looked pretty.

I served some of it warm, then chilled the rest later and cut it into little appetizer pieces. And honestly, that’s when I really fell for it. One recipe, two uses. Breakfast and appetizer. Cozy and convenient. It felt like the quiche was doing more multitasking than I was, and I respected that.

If your crust corners look a little patched, don’t worry. Mine usually do too. Nobody is going to lean over the platter and inspect your pastry seams. They’re going to grab a piece, maybe ask what’s in it, and then reach for another one. That’s the goal, right?

Why you’ll Love this Sheet Pan Quiche?

You’ll love this Sheet Pan Quiche because it gives you the creamy, savory comfort of classic quiche without making the whole process feel precious. Instead of one round quiche that needs neat slices, you get a flat, easy-to-cut quiche that can be served in squares, rectangles, or little appetizer cubes. It’s relaxed but still pretty. That’s my favorite kind of recipe personality.

One of the biggest wins here is the store-bought pie crust. It saves time, keeps things simple, and still gives the quiche that flaky base everyone expects. I’m not against homemade crust, not at all, but I do think there’s a time and place for shortcuts. And when you’re trying to get brunch on the table before everyone starts hovering in the kitchen, store-bought crust feels like a blessing.

This easy sheet pan quiche is also great for feeding a group. Since it makes around 32 pieces, it’s perfect for brunch spreads, potlucks, holiday mornings, appetizer trays, or meal prep. You can serve it warm and cozy, or chill it and make it into bite-sized party food. I don’t know about you, but I love when a recipe gives me options instead of demands.

The flavor combination is simple, but it works so well. Ham and cheese are classic for a reason, and the cheddar Monterey Jack blend melts into the eggs beautifully. The sun-dried tomatoes add a sweet-tangy bite, and the green onions bring freshness. The Dijon mustard is subtle, but it gives the filling a little zip. Not enough to make anyone say, “Is this mustardy?” Just enough to make the quiche taste more awake.

Another reason I keep coming back to this Sheet Pan Quiche is that it stores well. You can keep it in the refrigerator for up to 5 days, which means quick breakfasts, easy lunches, and little snacky bites are ready whenever you need them. There’s something comforting about knowing a container of quiche is waiting in the fridge. Like your past self did you a favor.

And maybe best of all, this recipe is forgiving. The crust can be patched. The fillings can be swapped. The pieces don’t have to be exactly the same size. It’s not fussy, and honestly, I appreciate that. Some recipes make you feel like you’re taking an exam. This one feels more like a helpful friend who brought a casserole and didn’t ask too many questions.

Ingredient Notes

The ingredients in this Sheet Pan Quiche are simple, but each one brings something useful to the pan. You’re making a creamy egg base, layering it over pie crust, and filling it with cheese, ham, sun-dried tomatoes, and green onions. Nothing too wild. Just familiar ingredients coming together in a way that feels a little more special than the effort required.

• Eggs: Eggs are the base of this Sheet Pan Quiche, giving it structure and that classic quiche texture. You’ll use 6 eggs, which mix with the half and half to create a creamy filling that sets as it bakes. I like to beat the eggs well before adding the rest, because it helps the filling bake more evenly. Nobody wants a random streak of unmixed egg white showing up like it forgot the assignment.
• Half and half: Half and half makes the quiche creamy without making it feel overly heavy. It’s basically a mix of milk and cream, and you can usually find it near the milk or coffee creamers. You could use heavy cream if you want something richer, or whole milk if you want it lighter, but I think half and half lands in that nice middle place. Creamy, but not “I need to lie down after brunch” creamy.
• Dijon mustard: Dijon mustard adds a little tang to the egg mixture. It doesn’t make the sheet pan egg quiche taste strongly like mustard, so don’t worry if you’re not a huge mustard person. It just gives the filling a bit more depth and keeps the eggs, cheese, and ham from tasting too flat. It’s a quiet helper ingredient, and I’m always fond of those.
• Salt and pepper: Salt and pepper season the egg mixture and bring out the flavor of the fillings. Since ham and cheese are already salty, you don’t need to be too aggressive here. The recipe uses 1/2 tsp salt and 1/4 tsp pepper, which is a good starting point. You can always adjust next time depending on the ham and cheese you use.
• Store-bought pie crust: Store-bought pie crust keeps this easy sheet pan quiche quick and low-stress. You’ll roll it out slightly, place it into the pan, trim the rounded edges, and use those trimmed pieces to patch the corners. It may look a bit odd at first, but I promise it comes together. Once the filling bakes, those little patched spots disappear into the background like they were never part of the drama.
• Cheddar and Monterey Jack cheese blend: This cheese blend gives you both flavor and meltiness. Cheddar adds a bit of sharpness, while Monterey Jack melts smoothly into the egg filling. Together, they make the quiche taste rich and cheesy without overpowering the ham and tomatoes. It’s a friendly, crowd-pleasing cheese combo.
• Cubed ham: Ham adds savory flavor and makes this ham and cheese sheet pan quiche hearty enough for breakfast or brunch. Cubed ham works nicely because it spreads evenly across the crust, so every piece gets a little bit. Leftover holiday ham is perfect here too, especially when you’re tired of eating it the same way over and over.
• Sun-dried tomatoes in oil: Sun-dried tomatoes add sweet, tangy flavor and a little richness from the oil. Chop them before adding so they spread evenly through the quiche. I think they make the whole recipe feel brighter and a little more grown-up, without making it complicated. A small ingredient, but it does a lot.
• Green onions: Green onions add freshness, color, and a mild onion flavor. They cut through the richness of the eggs, cheese, and ham just enough. They also make the finished Sheet Pan Quiche look prettier, and yes, I do care about that a little. We eat with our eyes first, or at least we take pictures with them.

How to Make Sheet Pan Quiche?

Making Sheet Pan Quiche is easier than it may look at first. You’ll prepare the pan, fit the pie crust, whisk the egg mixture, sprinkle the fillings over the crust, pour the custard on top, and bake until the center is puffed and slightly firm. It’s simple, but there are a few little tricks that make the process smoother—especially the part where you pour the egg mixture into the pan without creating a breakfast flood.

Step 1: Preheat the Oven

Preheat your oven to 350°F. This moderate temperature helps the egg filling bake gently and evenly. Quiche doesn’t really like being rushed. If the oven is too hot, the edges can overcook before the center sets. Slow and steady gives you a better texture, which is exactly what we want for this Sheet Pan Quiche.

Step 2: Prepare the Pan

Spray a 15×10-inch baking sheet with nonstick spray. You can also use a 9×13-inch baking dish if that’s what you have. The sheet pan gives you thinner pieces, which are great for appetizers or brunch bites. The baking dish makes a thicker quiche, which is nice for breakfast servings. Either way works, so don’t stress. Use the pan that matches your plan—or, let’s be honest, the one that’s clean.

Step 3: Fit the Pie Crust

Slightly roll out one sheet of store-bought pie crust and place it into the prepared pan. Since the crust is round and the pan is rectangular, some edges will hang over. Trim those pieces with a sharp knife and press the extra dough into the corners to fill in the gaps. It might look patchy at first. Mine usually does. But this is one of those moments where “good enough” truly is good enough.

Step 4: Beat the Eggs

In a large bowl, beat the eggs until the yolks and whites are fully combined. This helps create a smooth filling. You don’t need to whisk aggressively like you’re training for an arm workout, but do make sure everything is blended well. A smoother egg mixture means a smoother sheet pan breakfast quiche later.

Step 5: Add the Half and Half, Mustard, Salt, and Pepper

Whisk the half and half, Dijon mustard, salt, and pepper into the beaten eggs. Keep whisking until the mixture looks smooth and the mustard is fully blended in. The Dijon may take a moment to disappear into the mixture, but it will. This creamy custard is what holds all the fillings together and gives the quiche that soft, sliceable texture.

Step 6: Add the Fillings to the Crust

Sprinkle the cubed ham, cheddar Monterey Jack cheese blend, chopped sun-dried tomatoes, and green onions evenly over the unbaked pie crust. Try to spread everything out so every slice gets a little of each ingredient. If one area gets extra cheese, I suppose that’s not the worst problem to have. Lucky slice.

Step 7: Pour the Egg Mixture Over the Filling

Place the pan onto the oven rack before pouring in the egg mixture. This is a small but very helpful trick. Carrying a full sheet pan of liquid egg across the kitchen is not my idea of fun, and it never ends well if someone bumps your elbow. Slowly pour the egg mixture over the fillings so it settles evenly into the pan.

Step 8: Bake Until Set

Bake the Sheet Pan Quiche for 45 to 50 minutes, or until the center is puffed up and slightly firm. The middle should not look wet or loose. A little jiggle is okay, but it shouldn’t move like liquid. If it still looks too soft, give it a few more minutes. Quiche is done when it looks set and confident, which is a strange thing to say about eggs, but there we are.

Step 9: Cool and Slice

Remove the quiche from the oven and let it cool slightly before slicing. If you’re serving it warm for breakfast or brunch, cut it into squares or rectangles. If you’re serving it chilled as an appetizer, refrigerate it for at least 3 hours first, then slice it into smaller cubes or bite-sized pieces. Chilling helps the pieces firm up and cut more neatly.

Step 10: Serve Warm or Chilled

Serve this Sheet Pan Quiche warm, at room temperature, or chilled. Warm pieces feel cozy and brunchy, while chilled cubes make easy appetizers. That’s one of my favorite things about this recipe—it’s flexible. It doesn’t make you choose one serving style. Very considerate for a pan of eggs.

Storage Options

This Sheet Pan Quiche stores beautifully, which makes it perfect for make-ahead brunches, weekday breakfasts, appetizers, or quick “I need something from the fridge” snacks. Since it can be served warm or cold, you have a lot of room to work with. I love that kind of recipe, especially when the week gets busy and cooking every morning is just not happening.

• Refrigerator: Store leftover Sheet Pan Quiche in an airtight container in the refrigerator for up to 5 days. Let it cool completely before covering so steam doesn’t make the crust soggy. If you’re stacking pieces, place parchment paper between layers so they stay neat and don’t cling together like they’re forming a tiny quiche tower.
• Serving chilled: If you want to serve this quiche as an appetizer, chill it for at least 3 hours before slicing it into cubes or small rectangles. Cold quiche holds together better, which makes cleaner cuts and prettier appetizer pieces. This is especially helpful for party trays or brunch boards.
• Reheating in the oven: Reheat warm slices in a 325°F oven until heated through. This helps keep the crust from getting too soft and brings back a little of that fresh-baked texture. It takes longer than the microwave, but I think it’s worth it if you have the time.
• Reheating in the microwave: You can microwave individual pieces for a quick breakfast or snack. The crust will soften, but the flavor will still be good. Some mornings are not about crisp crust. Some mornings are about getting food into your body before emails start happening.
• Freezing: You can freeze baked Sheet Pan Quiche, though the egg filling may become slightly softer after thawing. Wrap individual pieces tightly in plastic wrap and foil, then place them in a freezer-safe bag or container. Freeze for up to 2 months. It’s handy, especially if you like having a few ready-to-reheat pieces tucked away.
• Thawing: Thaw frozen quiche overnight in the refrigerator before reheating. For the best texture, reheat in the oven instead of the microwave. The oven helps the crust recover a little, which is always appreciated.
• Make-ahead tip: This easy sheet pan quiche is a great make-ahead recipe. Bake it the day before, cool it completely, cover it, and refrigerate. Serve it cold as an appetizer or reheat it gently for brunch. It’s the kind of thing that makes you look like you planned ahead, even if the rest of your morning is held together with coffee and hope.

Variations & Substitutions

This Sheet Pan Quiche is easy to customize, which makes it a very useful recipe to keep around. The base is simple: eggs, half and half, crust, cheese, and fillings. Once you have that, you can change the meat, cheese, vegetables, and seasonings depending on what you like or what’s sitting in your fridge giving you that “please use me” look.

• Use different cheese: Cheddar and Monterey Jack are great, but Swiss, Gruyère, mozzarella, feta, pepper Jack, or Colby Jack can all work in this Sheet Pan Quiche. Swiss and Gruyère give it a classic brunch flavor, while pepper Jack adds a little heat. Feta gives it a salty, tangy bite. Choose what sounds good, or what you already have shredded in a bag. We are practical people.
• Swap the ham: Cubed ham works beautifully, but cooked bacon, breakfast sausage, turkey, chicken, or leftover holiday ham can also be used. Just make sure any meat is cooked before it goes into the quiche. Leftover ham after a holiday is especially nice here because it makes the recipe feel like a smart use of leftovers instead of the same plate reheated again.
• Make it vegetarian: Skip the ham and add vegetables instead. Spinach, mushrooms, bell peppers, zucchini, broccoli, asparagus, or caramelized onions would all be delicious. Cook watery vegetables first so they don’t release too much moisture into the filling. Mushrooms and spinach especially love to surprise you with extra liquid.
• Add herbs: Fresh parsley, chives, basil, thyme, or dill can brighten the filling. Chives are especially good with eggs and cheese. Herbs make this sheet pan egg quiche taste fresh and look a little more polished without requiring much work.
• Use a different crust: Store-bought pie crust keeps things easy, but puff pastry, crescent roll dough, or homemade pie crust can also work. Puff pastry gives a flakier bite, while crescent dough makes the base softer and more buttery. Homemade crust is lovely too, if you’re in the mood. I’m not always in the mood, but I admire people who are.
• Try different vegetables: Roasted red peppers, asparagus, kale, cherry tomatoes, sautéed mushrooms, or cooked broccoli can be added. Just avoid piling in too many wet toppings at once. A watery quiche is not the surprise we’re hoping for at brunch.
• Make it spicy: Add pepper Jack cheese, chopped jalapeños, crushed red pepper flakes, or a pinch of cayenne. This gives the sheet pan breakfast quiche a little kick without changing the whole recipe. Start small if you’re serving a crowd, because not everyone wants spicy eggs before noon.
• Use milk instead of half and half: Whole milk can be used instead of half and half, but the filling will be a little less rich. Heavy cream can be used for a richer texture. I personally like half and half because it feels balanced—creamy, but not too heavy.
• Make smaller appetizer bites: Chill the quiche for at least 3 hours, then cut it into small cubes or rectangles. Add toothpicks if you’re serving it on a party tray. People love tiny food. It makes them say things like “I’ll just have one,” which is almost never true.
• Add more color: Extra green onions, chopped herbs, diced peppers, or a little paprika can make the finished Sheet Pan Quiche look brighter and more inviting. It’s a small touch, but it helps, especially if you’re serving it to guests or photographing it for later.

What to Serve With Sheet Pan Quiche?

This Sheet Pan Quiche is rich, savory, and satisfying, so I like serving it with sides that are fresh, crisp, fruity, or lightly sweet. You can make it part of a brunch spread, serve it warm for breakfast, pair it with soup for lunch, or chill it and put it on an appetizer tray. It’s easygoing like that, which is honestly one of its best qualities.

• Fresh fruit: Berries, melon, grapes, pineapple, or orange slices are refreshing next to Sheet Pan Quiche. The sweetness balances the savory ham, cheese, and eggs. Plus, fruit makes the plate look cheerful and colorful, like you put in more effort than you probably did.
• Fruit salad: A fruit salad with honey, lime, or mint makes the meal feel brighter and more brunch-ready. It’s especially nice for holidays, baby showers, or weekend guests. It gives the table that “yes, this is a real brunch” feeling.
• Green salad: A crisp green salad with vinaigrette pairs nicely with warm quiche. The dressing cuts through the richness of the creamy egg filling and cheese. This is a great option if you’re serving Sheet Pan Quiche for brunch, lunch, or even a light dinner.
• Roasted potatoes: Crispy roasted potatoes or breakfast potatoes make this sheet pan breakfast quiche feel like a full meal. Potatoes and eggs have always been a solid team. I don’t question it.
• Toast or biscuits: Toast, biscuits, or English muffins work well on the side. Yes, the quiche already has crust, but brunch carbs operate under their own rules. Sometimes extra bread is just part of the mood.
• Soup: For lunch or dinner, pair Sheet Pan Quiche with tomato soup, vegetable soup, potato soup, or a simple broth-based soup. It turns the quiche into a cozy meal without adding too much work.
• Fresh vegetables: If you’re serving chilled quiche as an appetizer, add fresh vegetables like carrots, cucumbers, celery, bell peppers, and cherry tomatoes. A creamy dip on the side makes it feel like a complete party tray.
• Brunch drinks: Coffee, orange juice, iced tea, sparkling water, or mimosas all work well with quiche. Coffee for regular mornings, sparkling drinks for celebrations, and mimosas for when you want the brunch to feel like it has a tiny vacation attached.
• Sliced avocado: Avocado adds creaminess and freshness. Add a little salt, pepper, and lemon juice, then serve it beside warm quiche. It pairs especially well with ham, cheese, green onions, and sun-dried tomatoes.
• Yogurt parfaits: Yogurt with fruit and granola is a nice lighter side. It balances the richness of the quiche and gives the table a sweet option without going full dessert. Though honestly, brunch dessert is not a bad concept.

FAQ

Can I use a 9×13 baking dish instead of a sheet pan?

Yes, you can use a 9×13-inch baking dish instead of a 15×10-inch sheet pan. The quiche will be thicker, so it may need a little extra baking time. Check the center before taking it out of the oven. It should be puffed and slightly firm, not loose or watery.

Do I need to pre-bake the pie crust?

No, you do not need to pre-bake the pie crust for this Sheet Pan Quiche. The crust bakes along with the filling. Since the quiche bakes for 45 to 50 minutes, the crust has enough time to cook through.

Can I make this recipe vegetarian?

Absolutely. Leave out the ham and add cooked vegetables instead. Spinach, mushrooms, bell peppers, broccoli, zucchini, asparagus, or caramelized onions all work well. Just cook watery vegetables first so the quiche doesn’t become watery.

Why is my quiche watery?

A watery quiche usually means it was underbaked or the fillings released too much moisture. Make sure the center is fully set before removing it from the oven. If you add vegetables like spinach, mushrooms, or tomatoes, cook or drain them first to remove extra liquid.

This Sheet Pan Quiche is creamy, savory, easy to slice, and honestly just very useful.
