Shrimp and Crab Alfredo Ingredients
For the Pasta
• Fettuccine – The main pasta base that offers a hearty texture; feel free to substitute with your favorite pasta type.
For the Seafood
• Shrimp – Fresh, peeled, and deveined shrimp gives the dish a delightful flavor; you can also use scallops or a mix of seafood.
• Crab Meat – Adds an elegant sweetness to the dish; fresh lump crab meat is best, but canned options work in a pinch. For a twist, consider using lobster or imitation crab.
For the Sauce
• Butter – Adds richness and depth to the Alfredo sauce; olive oil is a lighter substitute.

Shrimp and Crab Alfredo Recipe FAQs
What type of shrimp should I use for Shrimp and Crab Alfredo?
Absolutely! I recommend using fresh, peeled, and deveined shrimp for the best flavor and texture. Look for shrimp that are firm and have a translucent appearance. If fresh isn’t available, high-quality frozen shrimp can work too; just make sure to thaw them completely before cooking.
How do I store leftovers of Shrimp and Crab Alfredo?
Storing leftovers properly is key! Place your Shrimp and Crab Alfredo in an airtight container and refrigerate for up to 2 days. When reheating, use low heat on the stove, adding a splash of cream or milk to restore the sauce’s creamy consistency to make it just as delicious as before!
Can I freeze Shrimp and Crab Alfredo?
Yes, you can freeze it, but it’s best to keep the pasta and sauce separate. Store the seafood sauce in a freezer-safe container for up to 3 months. When you’re ready to enjoy, thaw the sauce overnight in the refrigerator and reheat on the stove, then mix in freshly cooked pasta.
What should I do if my Alfredo sauce is too thick?
If you find your sauce is too thick, no need to worry! Just pour in a little pasta cooking water, a splash at a time, while stirring until you achieve your desired consistency. You can also add extra cream for a richer sauce, keeping in mind to adjust your seasonings afterward.
Is Shrimp and Crab Alfredo suitable for people with allergies?
Great question! Keep in mind that this dish contains seafood and dairy, which are common allergens. If you’re accommodating someone with allergies, consider using imitation crab and lactose-free cream or a dairy alternative like cashew cream. Always check with your guests for any specific dietary restrictions!
How can I ensure my shrimp are perfectly cooked?
Cooking shrimp to perfection is simple and crucial! Cook them in the sauce until they are just pink and opaque, which typically takes about 3-4 minutes. Avoid overcooking, as they can become rubbery. If in doubt, check for a firm texture; they should spring back when pressed.
