Shrimp Alfredo with Garlic Butter
Not rated yet. Be the first.
Shrimp sear first and come out tender, and the browned bits they leave behind flavor the cream. Parmesan melts in off the heat and lemon zest finishes it, so a plain weeknight feels like an occasion.
The short version
Sear seasoned shrimp for about 2 minutes and set them aside, simmer garlic and cream in the same pan, melt in Parmesan off the heat, toss with fettuccine and pasta water, return the shrimp. About 35 minutes.
What makes ours better
small changes, very loud compliments
-
Sear the shrimp first and use the same pan. The browned bits left behind season the sauce, and cooking the shrimp separately for only 2 minutes keeps them from turning rubbery in the cream.
-
Reduce the cream before adding cheese. A few minutes of simmering thickens the cream so the sauce coats the pasta without needing flour, and keeps it from getting thin and watery.
-
Melt the Parmesan off the heat. Cheese melts into cream smoothly at a gentle temperature. On high heat it turns grainy and oily.

Steps
apron on. phone down. mostly.
-
Season the shrimp
Toss the dry shrimp with half the salt, half the pepper and the paprika. Bring a large pot of water to a boil and salt it well, about 2 tablespoons kosher salt.
-
Sear the shrimp
Heat the oil in a large, deep skillet over medium-high heat until it shimmers. Add the shrimp in a single layer and cook for 1 to 2 minutes per side, until pink and just opaque and curled into a loose C. They will finish cooking in the sauce. Move them to a plate.
A tight O shape means they're overcooked. Pull them a little early.
About 3 min. Cook mode has a timer for this step.
-
Cook the pasta
Add the fettuccine to the boiling water and cook until just short of al dente, 1 to 2 minutes less than the package says. Scoop out 1 cup of the pasta water, then drain.
About 9 min. Cook mode has a timer for this step.
-
Start the sauce
Lower the skillet heat to medium and add 2 tablespoons of the butter. When it melts, add the garlic and cook for 30 seconds, scraping up the browned bits. Pour in the cream and the remaining salt and pepper and simmer for 3 to 4 minutes, until reduced by about a quarter and thick enough to coat a spoon.
Keep the garlic moving. If it browns it turns bitter.
-
Melt in the cheese
Take the pan off the heat. Add the Parmesan a handful at a time, whisking until each addition melts. Stir in the lemon zest and the remaining 2 tablespoons butter.
-
Toss the pasta
Add the pasta to the sauce with ¼ cup of the pasta water and toss over low heat for 1 minute, adding more water by tablespoons until the sauce is silky and clings to the noodles.
-
Add the shrimp and serve
Return the shrimp and any juices on the plate to the pan and toss for 30 seconds to warm through. Scatter with parsley and serve right away with more Parmesan and black pepper.
Good to know
the stuff I’d tell you over the phone
- Thaw frozen shrimp in a bowl of cold water for 10 to 15 minutes, then pat them very dry. Wet shrimp steam instead of searing.
- Buy a block of Parmesan and grate it yourself. Pre-shredded cheese has coatings that keep the sauce from getting smooth.
- For a lighter sauce, use 1 cup of cream and ½ cup of the pasta water. A handful of baby spinach or steamed broccoli folded in at the end is a good addition.
- Storage. Fridge, 2 days. The sauce tightens, so reheat in a skillet over low heat with a splash of milk or water, and warm the shrimp only briefly or they turn tough.
Questions, answered
asked and answered at the kitchen counter
How do I keep shrimp from getting rubbery?
Cook them for just 2 to 3 minutes total, until pink and curled loosely, and take them out of the pan. They finish in the sauce at the end. Overcooked shrimp curl into tight Os.
Why did my Alfredo sauce get grainy or oily?
The heat was too high or the cheese was pre-shredded. Take the pan off the heat before adding block-grated Parmesan, and whisk until it melts.
Can I use half-and-half or milk?
Not for this one. Lower-fat dairy doesn't reduce and can curdle once the cheese goes in. Use heavy cream.
Can I make shrimp Alfredo ahead of time?
The sauce is best fresh, but you can prep everything ahead. Grate the cheese and peel the shrimp up to a day in advance. Cook the dish just before serving.
Which shrimp size should I buy?
Large, 21 to 25 per pound, are the easiest to time. For smaller ones, cook 1 minute per side. For jumbo, add a minute.
