Instructions
Bring a large pot of salted water to a boil and cook fettuccine until firm-tender, about 10 minutes. Reserve 1 cup pasta water before draining. Do not rinse pasta.
Pat shrimp very dry with paper towels and season with salt and black pepper.
Add shrimp in a single layer and cook 1 to 2 minutes per side until pink, opaque, and curled into a C shape. Remove immediately to a clean plate. Discard any liquid if shrimp released water to keep sauce thick.
Reduce heat to medium and melt remaining 2 tablespoons butter in the same skillet. Add garlic and cook 30 seconds until fragrant but not brown. Keep at a low simmer, not a hard boil, to prevent curdling and to maintain a smooth creamy base for cheese.
Remove skillet from heat and gradually whisk in Parmesan until melted and smooth. Taste and adjust salt and pepper. Parmesan varies in saltiness, so add salt gradually.
The sauce should be rich but pourable, not pasty, before pasta is added.
Add shrimp back with any accumulated juices and toss 30 to 60 seconds just to warm. If needed, loosen with more pasta water. The final dish should glisten with sauce clinging to each strand rather than pooling heavily at the bottom.
Serve immediately in warm bowls topped with extra Parmesan and chopped parsley. Check shrimp are hot and pasta is creamy. Serve with lemon wedges if desired for brightness.
Refrigerate leftovers promptly within 2 hours.
Troubleshooting — fixes, not repeats
- If shrimp are rubbery, they overcooked. Cook just until pink and opaque, then remove promptly from heat.
- If Alfredo separates, heat was too high when cheese was added. Melt cheese off boil and add gradually.
- If sauce is too thick, thin with warm pasta water or milk. Pasta starch helps sauce cling smoothly.
- If shrimp release water, pat dry before cooking and avoid crowding pan so they sear not steam.
Make it your way
- Spicier version: Add 1/2 teaspoon Cajun seasoning for spicy shrimp Alfredo.
- For variation, add 2 cups steamed broccoli, peas, or sun-dried tomatoes for color and vegetables.
- Replace shrimp with diced chicken cooked to 165°F for a chicken Alfredo version.
- Use half-and-half instead of cream for lighter sauce, simmering slightly longer to thicken.
Storage & reheating
Cool leftovers within 2 hours, then refrigerate in a covered container and use within 3 to 4 days. Reheat only the portion you will eat until steaming hot throughout — poultry and reheated rice should reach 165°F (74°C).
Reheat in a skillet over low heat to 165°F with 2 to 4 tablespoons milk, stirring gently until creamy.
Microwave in 30-second intervals with stirring.
FAQ
Can I use frozen shrimp?
Yes. Thaw overnight in the refrigerator, then drain and pat very dry. Do not cook from frozen because excess water thins sauce and shrimp steam instead of searing evenly.
Can I use milk instead of cream?
Whole milk works but makes thinner sauce. Simmer longer to reduce, add 2 tablespoons cream cheese for body, and stabilize with pasta water for better clinging.
How do I prevent bland Alfredo?
Salt pasta water well, use fresh garlic and real Parmesan, and finish with black pepper and lemon. Taste sauce before adding pasta and adjust salt gradually.
