½ teaspoon black pepper (freshly ground)

¼ teaspoon nutmeg (optional, for depth)

For the Crab:

1 tablespoon olive oil or butter (for warming crab)

Pinch of red pepper flakes (optional, for a hint of heat)

 Step-by-Step Instructions
Step 1: Cook the Fettuccine
-
Bring a large pot of salted water to a boil.
-
Add the fettuccine and cook according to package directions until al dente (usually 9–11 minutes).
-
Reserve 1 cup of the starchy pasta water before draining.
-
Drain the pasta and set aside.
Step 2: Prepare the Crab
-
In a skillet, heat 1 tablespoon of olive oil or butter over medium heat.
-
Add the crab meat and gently warm it through for 2–3 minutes.
-
Avoid overcooking; crab meat is delicate and only needs to be heated.
-
-
Sprinkle in red pepper flakes if you want a slight kick.
-
Remove from heat and set aside.
Step 3: Make the Alfredo Sauce
-
In a large skillet or saucepan, melt 4 tablespoons of butter over medium heat.
-
Add the minced garlic and sauté for 1–2 minutes until fragrant (do not burn).
-
Pour in the heavy cream and bring to a gentle simmer.
-
Stir in Parmesan and Pecorino cheese, whisking until smooth and creamy.
-
Season with black pepper, nutmeg, and a pinch of salt (taste before adding too much salt since Parmesan is naturally salty).
-
If the sauce is too thick, add a splash of reserved pasta water to loosen.
Step 4: Combine Everything
-
Add the cooked fettuccine to the Alfredo sauce and toss to coat evenly.
-
Gently fold in the warmed crab meat.
-
Allow everything to heat together for 1–2 minutes over low heat, so flavors meld.
Step 5: Garnish and Serve
-
Plate the pasta into warm bowls.
-
Sprinkle with fresh parsley and extra Parmesan.
-
Serve with lemon wedges for squeezing over the top—this brightens the creamy richness.

Tips for the Best Crab Fettuccine Alfredo
