How to Make Quick and Delicious One Pot Shrimp and Crab Alfredo

1. In a large deep skillet or Dutch oven, heat olive oil over medium heat. Add shrimp seasoned with a pinch of salt and pepper; cook 2-3 minutes per side until pink and opaque. Remove shrimp and set aside.
2. Add butter to the same pot and melt. Stir in minced garlic and cook for about 1 minute until fragrant but not browned.
3. Pour in whole milk and heavy cream, stirring to combine. Bring the mixture to a gentle simmer over medium heat.
4. Add the pasta directly into the simmering sauce, submerging it fully. Cook uncovered, stirring occasionally, for about 10-12 minutes or until pasta is tender and most of the liquid is absorbed.
5. Once pasta is nearly cooked, stir in Parmesan cheese, salt, black pepper, and red pepper flakes if using. Mix until the cheese melts and the sauce thickens to a creamy consistency.
6. Gently fold in the cooked shrimp and crab meat, warming through for 2-3 minutes. Avoid stirring too vigorously to keep crab meat intact.
7. Remove from heat and stir in fresh lemon juice and chopped parsley for brightness and flavor.
8. Serve immediately, garnished with extra parsley and freshly cracked black pepper. Enjoy your creamy one pot shrimp alfredo with crab!

Tips for the Best Results

• Use fresh or thawed seafood for the best texture and flavor.
• Don’t overcook the pasta; check it a minute or two before the package instructions.
• Stir gently after adding crab to keep the delicate meat from breaking apart.
• For a thicker sauce, reduce the milk slightly or add more Parmesan cheese.
• Freshly grate your Parmesan cheese; it melts better and adds more flavor.

Storage and Reheating

Store any leftovers in an airtight container in the refrigerator for up to 2 days. The sauce may thicken as it cools; stir in a splash of milk or cream when reheating to loosen it back up.

You can also freeze the dish for up to one month. Thaw overnight in the fridge before reheating gently on the stovetop over low heat to preserve the creamy texture and seafood quality.

Frequently Asked Questions

Can I use frozen seafood for this recipe?

Yes, you can use frozen shrimp and crab, but be sure to thaw them completely and pat dry to avoid excess moisture. This will help keep the sauce from becoming watery.

What type of pasta works best for this dish?

Fettuccine or linguine works best because their flat shape holds the creamy Alfredo sauce well. However, you can also use spaghetti or penne if that’s what you have on hand.

Is there a substitute for heavy cream?

You can substitute half-and-half or whole milk, but the sauce will be less rich and creamy. For the best texture, stick with heavy cream or a mixture of milk and cream.

Can I make this recipe dairy-free?

To make a dairy-free version, use dairy-free butter, a plant-based cream substitute, and skip the Parmesan or use a vegan cheese alternative. Keep in mind the flavor and texture will be different.
