Ingredients

  • Fettuccine 250g / 8.8 oz: The flat strands hold the thick Alfredo sauce beautifully.
  • Butter 60g / 1/4 cup: Gives the sauce a rich, velvety base and golden sheen.
  • All-Purpose Flour 30g / 2 tbsp: Helps thicken the sauce without making it heavy.
  • Whole Milk 480ml / 2 cups: Adds creaminess and smooth texture without extra fat.
  • Cream Cheese 100g / 3.5 oz: Brings tang and a luxurious mouthfeel to the Alfredo.
  • Parmesan Cheese 60g / 1/2 cup grated: Adds nutty, salty depth and creamy consistency.
  • Lump Crabmeat 225g / 8 oz: The sweet, briny highlight of the dish—go fresh or high-quality canned.
  • Garlic Powder 1/2 tsp: Enhances the seafood flavor gently without overpowering.
  • Onion Powder 1/2 tsp: Adds subtle warmth to balance the richness of the sauce.
  • Fresh Parsley 2 tbsp, chopped: Brightens the dish and adds a pop of green.
  • Salt & White Pepper to taste: Balances flavor; white pepper keeps the sauce clean-looking.

Instructions

  • Step 1 – Cook the Pasta
  • Boil fettuccine in salted water until al dente. Drain and set aside.
  • Step 2 – Start the Sauce
  • In a large skillet, melt butter over medium heat. Whisk in the flour and cook for 1 minute to remove raw taste.
  • Step 3 – Add Dairy
  • Slowly whisk in milk, then stir in cream cheese until fully melted and smooth.
  • Step 4 – Season It
  • Add Parmesan, parsley, garlic powder, onion powder, salt, and white pepper. Whisk until creamy.
  • Step 5 – Fold in the Crab
  • Gently add crabmeat and warm through for 2–3 minutes on low heat. Avoid over-stirring.
  • Step 6 – Combine & Serve
  • Toss the pasta in the sauce or spoon it over plated noodles. Garnish with extra parsley or lemon zest if desired.

Notes

Don’t Overcook Crab: It’s already cooked. Just warm it gently to preserve tenderness.
Use Fresh Parmesan: Pre-grated won’t melt as smoothly or taste as rich.
Add Lemon Zest: Brightens the dish without overpowering the delicate crab.
Low Heat Only: High heat can cause the sauce to break or crab to toughen.
This creamy crab fettuccine feels like dining out at a seaside bistro—but it's even better because it comes with soft socks, your favorite playlist, and no reservations. I hope this recipe brings your family as much joy as it brings mine.
