Key Ingredients
Shrimp
Shrimp adds a juicy, tender bite and cooks quickly, making this recipe easy enough for a weeknight. Cook it just until pink and opaque so it stays tender.
Crab Meat
Crab meat brings a sweet, delicate seafood flavor that makes the Alfredo feel extra special. Fresh crab works best, but canned crab can be used as long as it is drained well.
Fettuccine
Fettuccine is a classic choice because the wide noodles hold onto the creamy Alfredo sauce. You can also use linguine, spaghetti, or penne if that is what you have on hand.
Heavy Cream
Heavy cream creates the rich base of the Alfredo sauce. It gives the sauce a smooth texture and helps the cheese melt into a creamy finish.
Parmesan and Romano Cheese
Parmesan gives the sauce its salty, nutty flavor, while Romano adds a sharper bite. Romano is optional, but it helps deepen the flavor of the sauce.
Step-by-Step Instructions
1. Cook the Pasta
Bring a large pot of salted water to a boil and cook the pasta until al dente, according to package directions. Before draining, reserve a small amount of the pasta water to adjust the sauce later. Drain and set aside.
2. Cook the Seafood
In a large skillet, heat olive oil over medium heat. Add the shrimp and cook for a few minutes on each side, until pink and opaque. Remove and set aside.
Add the crab meat to the same skillet and sauté briefly to warm it through. Set aside with the shrimp.
3. Make the Alfredo Sauce
In the same pan, melt the butter over medium heat. Add the minced garlic and sauté for about a minute, until fragrant.
Pour in the cream and bring to a gentle simmer. Gradually stir in the Parmesan and Romano cheeses until melted and smooth. Season with salt, pepper, and Italian seasoning if desired.
If the sauce becomes too thick, add a splash of the reserved pasta water until the desired consistency is reached.
4. Combine Everything
Add the cooked pasta to the sauce and toss until evenly coated. Gently fold in the shrimp and crab meat and cook for another minute or two, just until heated through.
5. Serve
Transfer the pasta to serving plates and garnish with freshly chopped parsley. Serve immediately for the best flavor and texture.
What to Serve with Shrimp and Crab Alfredo
This rich pasta pairs beautifully with light, fresh sides to balance its creaminess. Try serving it with:
- Garlic bread or toasted baguette slices
- A crisp Caesar salad or simple green salad with lemon vinaigrette
- Roasted or steamed vegetables such as asparagus or broccoli
- A glass of chilled Chardonnay or Pinot Grigio
Variations
- Lighter version: Substitute half-and-half for the heavy cream or reduce the amount of cheese.
- Add vegetables: Stir in spinach, peas, or sautéed mushrooms for extra flavor and color.
- Add heat: Sprinkle in a pinch of red pepper flakes for a subtle kick.
- Try different seafood: Swap the crab for lobster, scallops, or even chunks of firm white fish.
- Extra flavor boost: Add a splash of white wine to the sauce before adding the cream for a more complex flavor.
Frequently Asked Questions
Can I use pre-cooked shrimp or crab?
Yes. If using pre-cooked seafood, add it at the very end just to warm through—avoid overcooking to keep it tender.
Can I make this ahead of time?
The sauce is best made fresh, but you can prepare the seafood and pasta a few hours in advance. Reheat gently over low heat and add a bit of cream or milk to loosen the sauce.
What kind of pasta works best?
Fettuccine is classic, but linguine, spaghetti, or even penne all work well. Choose a pasta shape that holds sauce nicely.
Can I use imitation crab?
You can, but the flavor will be milder. For the best taste, use real crab meat when possible.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to two days. Reheat gently on the stove over low heat, adding a splash of cream or milk to restore the sauce’s creaminess.
