Sometimes the simple things really are the best. It's certainly true of this shrimp Alfredo recipe. Garlicky shrimp and perfectly al dente strands of fettuccine pasta mingle with a rich and buttery Alfredo cream sauce. It's an indulgent Italian-American recipe that is sure to become a comfort food favorite in your kitchen. 

The sauce for this shrimp Alfredo is so good, you'll want to lick the plate clean. It's flavored just with fresh garlic and lemon, yet the dish is hearty enough to be a solid meal, thanks to protein-packed shrimp and carb-heavy pasta. A refreshing green salad or platter of steamed vegetables is always a good idea to round out the meal.

What Makes Shrimp Alfredo Special

The comforting Italian-American dish pairs juicy, plump shrimp with a classic creamy sauce. There are a few key ingredients (besides the obvious shrimp and pasta) that add layers of flavor to this dish:

  • Garlic: The garlic flavor in this recipe is subtle but important. Instead of mincing the garlic cloves, we crush them with the back of a knife. They are added along with shrimp when they’re sautéed, so the garlic flavor slowly infuses into the butter. 
  • Lemon: Both the zest and fresh juice of a lemon add a bright flavor to the finished dish. You can even grate more lemon zest over the top before serving to really bring the pasta and shrimp back to life. 
  • Butter: You could use olive oil to sauté the shrimp, but butter is even more flavorful. It will complement the creamy sauce perfectly. 
  • Heavy cream: This recipe uses a lot of heavy cream, but that’s what Alfredo sauce is all about! The cream melds with the cheese to create a silky sauce that coats each piece of shrimp and strand of pasta. 
  • Parmesan cheese: Pairing seafood with cheese can be controversial, but for this recipe, it works. The cheese is incorporated into the Alfredo sauce as well as being sprinkled over the top of each serving.

Choosing the Right Shrimp

Buying shrimp can be confusing. Sizing varies pretty drastically—and size matters for this pasta dish. Shrimp are sized by the number in a pound, and each grocery store and fish market uses different metrics when labeling their shrimp. This recipe calls for large shrimp, which usually range somewhere between 30 to 40 shrimp per pound. Since this recipe serves eight people, that would mean each serving has four or five large shrimp. 

Use your best judgment when purchasing shrimp for any recipe. For this dish, choose ones that you feel won’t be too large to eat in a few bites with the pasta.

This recipe is also delicious with slices of grilled chicken breast instead of shrimp.

The Best Pasta for Alfredo Sauce

Fettuccine is the classic noodle for any Alfredo dish. The long strands of pasta are perfect for soaking up the creamy sauce and twirling onto forks. Fettuccine is another good choice for this recipe because the shrimp won't get lost among the noodles. You could also use most other long noodles, such as spaghetti, linguine, or bucatini, instead.

Storing and Reheating

Leftover pasta and shrimp can be stored in an airtight container in the refrigerator for up to two days. Because of the cream sauce, we don't recommend freezing leftovers. 

Reheating

To reheat, pop the tray in the microwave in 30-second increments or warm up a portion in a skillet over low heat, being careful not to curdle the sauce. 

Store some of the pasta water separately in the refrigerator. If the Alfredo sauce seems thick as you reheat it, incorporate some of the starchy pasta water to loosen up the sauce.

Frequently Asked Questions

  • Can I use frozen shrimp for shrimp Alfredo?

    Yes, you can use frozen shrimp for shrimp Alfredo. Just be sure to thaw them in the refrigerator overnight before using.

  • How do I avoid overcooking shrimp?

    Shrimp are small and tender and easy to overcook. To avoid overcooking them, pull the shrimp from the skillet just as soon as they start to turn pink and curl up. There will be some residual heat from the pan, so even if they are slightly undercooked when you take them out of the skillet, they will get to a safe temperature as they rest.

  • What can I add to Alfredo sauce to make it taste better?

    This Alfredo sauce tastes really great and doesn't need extra help. It is far from bland. All of the lemon, garlic, and fat from the heavy cream create a rich, thick, and flavorful sauce. If you want to amp up that flavor even more, you could add a minced shallot when you sauté the shrimp or stir some garlic powder into the sauce before serving.

  • What can I serve shrimp Alfredo with?

    Any salad is the perfect accompaniment to shrimp Alfredo, but we’re partial to another classic–Caesar salad. Since the dish is so rich and indulgent, a fresh or lightly cooked vegetable is another great pairing.
