Servings: 6
Ingredients
- 4 large Vidalia onions halved and sliced 1/4-inch thick
- 2 tbsp unsalted butter
- 3 eggs
- 1 can 5 oz evaporated milk
- 1 c Ritz crackers crumbled
- 1 1/2 c cheddar cheese grated
- 1 tsp salt
- 1/4 tsp black pepper
For the Topping
- 1 c Ritz crackers crumbled
- 3 tbsp butter melted
Instructions
- Preheat the oven to 375°F. Grease a 9x13-inch baking dish with nonstick cooking spray.
- Place the sliced onions in a saucepan and add enough water to just cover them. Bring the water to a boil, then reduce the heat and simmer for 8 minutes.
- Drain the onions thoroughly and transfer them to a mixing bowl. Add the 2 tablespoons of unsalted butter and toss until the onions are evenly coated.
- In a separate large bowl, whisk together the eggs and evaporated milk until smooth.
- Add the cooked onions, 1 cup crumbled Ritz crackers, grated cheddar cheese, salt, and black pepper to the egg mixture. Stir until all ingredients are evenly combined.
- Transfer the onion mixture to the prepared baking dish and spread it into an even layer.
- In a small bowl, combine the remaining 1 cup crumbled Ritz crackers with the 3 tablespoons melted butter. Mix until the crumbs are evenly coated.
- Sprinkle the cracker topping evenly over the casserole.
- Bake for about 45 minutes, or until the casserole is set in the center and the topping is golden brown.
- Remove from the oven and allow the casserole to rest briefly before serving.
