Ingredient Notes

- Crab meat: Fresh or lump crab meat brings that sweet seafood taste to the dish. If you can, go for fresh; it makes a difference!
- Butter: A generous amount of butter adds richness and helps create that creamy sauce. I always grab good-quality salted butter for extra flavor.
- Freshly grated Parmesan cheese: Grating your own cheese gives a creamier texture and better melting. Trust me, it’s worth the little extra effort!
- Light cream: This helps create a silky sauce that balances well with the richness. You can use half-and-half in a pinch, but it’ll be a bit thicker.
- Fettuccine: The wide noodles are perfect for catching that creamy sauce. If you’re feeling adventurous, try it with tagliatelle or pappardelle instead!

Recipe Tips
- If the sauce becomes too thick, a splash of reserved pasta water can create a creamier consistency.
- When cooking fettuccine, stirring occasionally and using a generous amount of water can help prevent the pasta from breaking apart.
- For the smoothest sauce, freshly grated Parmesan should be added gradually and mixed off the heat to avoid clumping.
- If looking for flavor, salting the pasta water well is key for enhancing the overall taste of your crab Alfredo.
- If using pre-grated cheese, consider switching to fresh grated for a creamier sauce that will bind better with the pasta.
Serving Suggestions
- Serve crab Alfredo with garlic bread for a satisfying meal. Additional side options include a crisp green salad or sautéed vegetables.
- This dish works well in recipes like crab lasagna or seafood pasta bake. Use it in a crab salad or layered into a seafood casserole.
- Add extra grated Parmesan or a sprinkle of Old Bay for finishing touches on each serving. A drizzle of lemon juice adds brightness and freshness to the dish.
Storage Guidelines
- To keep your crab alfredo fresh, follow these storage tips:
- Refrigeration: Store in an airtight container in the refrigerator for up to 3 days to maintain freshness and quality.
- Freezing: Wrap tightly in plastic wrap or aluminum foil, then place in a freezer-safe bag or container. Freeze for up to 3 months. To serve, thaw overnight in the refrigerator before reheating.
- Reheating: Warm in a saucepan over low heat, stirring gently until heated through. Avoid high heat to prevent separation.
Recipe Variations
- You can use 1 pound of shrimp instead of crab for a delightful seafood twist.
- Add 1 teaspoon of garlic powder and 1 teaspoon of black pepper for extra flavor.
- Either choose penne or linguine in place of fettuccine for a different pasta experience.
- If you’re preparing a larger meal, increase the crab meat to 2 pounds and the butter to 1 1/2 cups.

Crab Alfredo

Equipment
- Large pot for boiling pasta
- Saucepan for making sauce
- grater for cheese
- Large Bowl for mixing
Ingredients
- 1 pound fettuccine (dried)
- 1 ½ cups light cream (360 ml)
- 1 cup butter (unsalted)
- 2 cups Parmesan cheese (freshly grated)
- 2 teaspoons Old Bay seasoning (10 grams)
- 1 pound crab meat (fresh)
- ¼ cup fresh parsley (chopped)
- Salt, to taste
Instructions
- Start by boiling a large pot of salted water. Once boiling, add the fettuccine. Cook until al dente, which should feel slightly firm to the bite. This should take approximately 10 minutes. Avoid overcooking to prevent mushy pasta.
- In a separate saucepan, melt the butter over low heat until it is bubbly and fragrant. Pour in the light cream, stirring gently until combined. Warm the mixture without boiling, aiming for a smooth consistency.
- Gradually stir in the freshly grated Parmesan cheese while letting it melt into the cream sauce. This should create a velvety mixture. Adding the cheese slowly helps prevent clumps.
- Sprinkle in the Old Bay seasoning into your sauce, stirring for even distribution. You should start to smell the spices coming together, taking care not to overpower the dish with too much seasoning.
- Add the cooked fettuccine directly into the creamy sauce and mix gently until every strand is coated evenly. The dish should look luscious. Avoid stirring too vigorously to keep the pasta intact.
- Gently fold in the crab meat, being cautious not to break it apart too much. The sweetness of the crab enhances the richness of the sauce. Avoid over-mixing to maintain texture.
- Just before serving, top your Crab Alfredo with the chopped fresh parsley. This adds color and aroma, enhancing the overall presentation.
