How to Make Crab Fettuccine Alfredo

Don’t be intimidated by this pasta! It’s so easy to make.

  1. Cook the pasta. Cook the fettuccine according to package instructions until al dente. Drain and set aside.
  2. Make the roux. In a large saucepan, melt the butter over medium heat. Add the minced garlic and cook for 1 minute. Whisk in the flour and cook for 2 minutes, stirring constantly.
  3. Add the dairy. Gradually whisk in the milk and heavy cream. Bring to a simmer and cook for 5-7 minutes, whisking frequently, until thickened.
  4. Add the cheese and seasonings. Remove from the heat. Stir in the Parmesan cheese, garlic powder, onion powder, salt, and pepper until the cheese is melted and incorporated.
  5. Fold in the crab. Gently fold in the crab meat and parsley. Be careful not to break up the lump crab too much.
  6. Toss with the pasta. Add the cooked fettuccine to the sauce and toss to coat the noodles evenly.
  7. Garnish and enjoy! Serve this dish immediately. Garnish with extra Parmesan cheese and chopped parsley if desired. Enjoy your delicious meal!

Tips For the Best Crab Fettuccine Alfredo

Following these tips and tricks will make your pasta the best it can be.

  • The fresher, the better. Use fresh, high-quality lump crab meat for the best flavor and texture. Avoid imitation or canned crab if possible.
  • Aim for al dente. Cook the fettuccine until just al dente so it doesn’t get mushy. Reserve some of the pasta cooking water to thin the sauce if needed.
  • Grate your own cheese. Always use freshly grated Parmesan cheese off the block. Pre-shredded cheese doesn’t melt as smoothly.
  • Watch the temp! Cook the sauce over gentle heat and don’t let it boil. This can cause the cheese to become grainy and the sauce to separate.
  • Throw in some flavor enhancers. Add flavor enhancers like garlic powder, onion powder, Old Bay seasoning, or a pinch of nutmeg.
  • Vary it up. Try adding sautéed onions, mushrooms, peas, or sun-dried tomatoes. Use different pasta shapes or substitute shrimp or lobster for the crab.

How to Store

If you have leftover Crab Fettuccine Alfredo, here’s how to store it to enjoy later:

To Store: Refrigerate leftovers in an air-tight container for up to 3-4 days. The sauce may separate and thicken as it cools but can be revived when reheating.

I don’t recommend freezing this recipe, as the consistency won’t be the same.

To Reheat: Gently reheat portions in a saucepan over low heat. Stir frequently and add a splash of milk or cream to loosen the sauce if needed. Avoid overcooking the crab meat.

You can also place portions in a microwave-safe dish and reheat at 50% power for 1-2 minutes. Stir halfway through, until heated through.
