Step-by-Step Instructions
1. Cook the Pasta
Bring a large pot of salted water to a boil. Add your fettuccine and cook according to package directions until al dente. Drain the pasta, reserving about 1/2 cup of the pasta water, and set it aside.
2. Sauté the Shrimp
While the pasta cooks, heat the olive oil in a large skillet over medium heat. Add the peeled and deveined shrimp and cook for 2-3 minutes per side, or until they turn pink and opaque. Remove the shrimp from the skillet and set them aside.
3. Make the Garlic Cream Sauce
In the same skillet, reduce the heat to medium-low. Add the minced garlic and sauté for about 30 seconds until fragrant. Pour in the heavy cream, stirring constantly. Bring the cream to a gentle simmer, then reduce the heat to low.
4. Finish the Alfredo Sauce
Gradually stir in the grated Parmesan cheese until it melts and the sauce thickens. Season with salt, black pepper, and optional red pepper flakes. If the sauce is too thick, add a tablespoon or two of the reserved pasta water until it reaches your desired consistency.
5. Combine and Serve
Add the cooked pasta and the sautéed shrimp back into the skillet with the Alfredo sauce. Toss gently to coat everything evenly. Garnish with fresh parsley, if you like, and serve immediately for a delightful pasta dinner recipe.
Variation Ideas
- Add some cooked, chopped broccoli or spinach for extra vegetables.
- Stir in a squeeze of fresh lemon juice at the end for brightness.
- Experiment with different pasta shapes like penne or rigatoni.
Storage Instructions
Store any leftover Creamy Garlic Shrimp Alfredo in an airtight container in the refrigerator for up to 2-3 days. When reheating, add a splash of milk or water to help loosen the sauce and gently warm it on the stovetop or in the microwave. Avoid overheating, as this can make the shrimp tough.
Frequently Asked Questions (FAQ)
Can I use pre-cooked shrimp?
Yes, you can use pre-cooked shrimp. Add them to the sauce at the very end, just long enough to warm through, to avoid overcooking.
What kind of pasta works best for Alfredo?
Fettuccine is traditional, but linguine, spaghetti, or even penne are excellent choices for this pasta dinner recipe.
How can I make the sauce thicker?
The sauce should thicken as the Parmesan melts. If it’s still too thin, you can add a little more Parmesan cheese, or you can mix a teaspoon of cornstarch with a tablespoon of cold water and whisk it into the simmering sauce.
Can I prepare the sauce ahead of time?
You can prepare the sauce a few hours in advance and store it in the refrigerator. Reheat gently over low heat, adding a splash of cream or milk if it’s too thick. Add shrimp and pasta just before serving.
What if my sauce separates?
Sauce separation can happen if it gets too hot too quickly. Reduce the heat and whisk vigorously. Adding a tiny bit of cold cream or pasta water can sometimes help bring it back together.
Is this a good weeknight pasta dinner recipe?
Absolutely! This dish is designed to be quick and easy, making it a perfect and satisfying pasta dinner recipe for any weeknight meal.
