This is a straightforward garlic butter shrimp Alfredo — fettuccine tossed in a Parmesan cream sauce with pan-seared shrimp, ready in 40 minutes. It uses a short ingredient list and one skillet for the sauce, which makes it genuinely useful on a busy weeknight. The result is rich without being fussy, and it reheats better than most cream pasta dishes if you handle it right.
What makes this version work
Two things matter here. First, the shrimp come out of the pan before the cream goes in. Leaving them in while the sauce reduces turns them rubbery — pulling them early and adding them back at the end keeps them tender. Second, the Parmesan has to be freshly grated, not the pre-shredded kind. Pre-shredded cheese is coated with starch to prevent clumping, and that starch makes the sauce grainy instead of smooth. Grate it yourself right before it goes into the pan and it melts cleanly into the cream.
Common problems and fixes
- Sauce is too thick by the time you serve it: Cream sauces tighten fast off the heat. Keep a small cup of the pasta cooking water nearby and stir in a tablespoon or two just before serving to loosen it back up without diluting the flavor.
- Sauce breaks and looks greasy: This usually happens if the heat is too high when you add the Parmesan. Take the pan off the burner entirely, add the cheese, and stir steadily. The residual heat is enough to melt it.
- Shrimp are watery and the sauce gets thin: Frozen shrimp release a lot of liquid if they go into the pan still wet. Pat them completely dry with paper towels before they hit the butter.
- Garlic tastes sharp or bitter: It burned. Garlic in butter over medium heat needs constant attention — 60 to 90 seconds is usually enough. If it starts to color at all, pull the pan off the heat immediately.
- Pasta clumps after draining: If you drain the fettuccine and then leave it sitting while you finish the sauce, it sticks together. Toss it with a tiny bit of butter or keep it in a splash of pasta water until you’re ready to combine.
Make-ahead notes
Leftovers keep well in an airtight container in the fridge for up to 3 days — skip the garnish, it’s not worth the extra dish. To reheat, put the pasta in a skillet over low heat with a splash of water or milk (about 2 tablespoons per serving) and stir until the sauce comes back together; the microwave works too but tends to make the shrimp tough, so pull the shrimp out, reheat the pasta separately, then add the shrimp back for just the last 30 seconds. If you want to get ahead for the week, cook a double batch of pasta and sauce and store them together, then sear a fresh batch of shrimp on the night you serve it — shrimp take under 5 minutes and taste noticeably better fresh. The sauce alone (without shrimp or pasta) can be frozen for up to 6 weeks in a freezer-safe container; thaw it overnight in the fridge and reheat gently, whisking to bring it back together before adding freshly cooked pasta and shrimp.

Equipment
- Large pot (for boiling pasta)
- 12-inch non-stick skillet
- Microplane or box grater (for fresh Parmesan)
- Wooden spoon or silicone spatula
- Colander
- Tongs for tossing pasta
Ingredients
- 1 lb fettuccine pasta 1 lb, preferably fresh
- 1 lb large shrimp peeled and deveined, 1 lb 2 oz
- 2 tablespoons unsalted butter 30g
- 4 cloves garlic minced
- 1 cup heavy cream 240ml, or double cream
- 1 cup Parmesan cheese freshly grated, 100g
- salt to taste
- black pepper freshly ground, to taste
- 2 tablespoons fresh parsley chopped, for garnish
Instructions
- Bring a large pot of generously salted water to a rolling boil. Cook 450g (1 lb) fettuccine until al dente — about 2–3 minutes for fresh pasta or 10–12 minutes for dried, following package directions. Reserve ½ cup (120ml) of pasta water before draining.1 lb fettuccine pasta
- In a large skillet, melt 2 tablespoons (30g) of unsalted butter over medium heat until it begins to froth slightly.2 tablespoons unsalted butter
- Add the minced garlic and sauté until fragrant, about 1 minute, stirring constantly so it does not brown.4 cloves garlic
- Add the shrimp to the skillet in a single layer. Cook for 2–3 minutes per side until pink and opaque. Transfer the shrimp to a plate and set aside.1 lb large shrimp
- Reduce the heat to medium-low. Pour 1 cup (240ml) of heavy cream into the same skillet, scraping up any browned bits from the shrimp. Bring to a gentle simmer and stir in 1 cup (100g) of freshly grated Parmesan, stirring continuously until the cheese melts and the sauce is smooth, about 2 minutes. Season with salt and freshly ground black pepper to taste. If the sauce is too thick, add a splash of reserved pasta water to loosen it.1 cup heavy cream, 1 cup Parmesan cheese, salt, black pepper
- Return the cooked shrimp to the sauce, followed by the fettuccine, tossing well to coat the pasta evenly with the rich Alfredo sauce.1 lb fettuccine pasta, 1 lb large shrimp
- Serve the dish immediately, garnished with fresh parsley for a vibrant finish.2 tablespoons fresh parsley

Frequently asked questions
Can I use pre-cooked shrimp to save time?
You can, but the texture suffers. Pre-cooked shrimp are already fully done, so any additional heat makes them rubbery — if you use them, just stir them into the finished sauce for 30 seconds to warm through, nothing more.
What can I use instead of heavy cream?
Half-and-half works and produces a thinner, lighter sauce. Avoid milk on its own — it doesn’t have enough fat to stay stable in the pan and the sauce is likely to separate.
Do I have to use fettuccine, or will other pasta shapes work?
Other shapes work fine. Linguine and pappardelle behave similarly to fettuccine; shorter shapes like rigatoni or penne also hold the sauce well in the ridges. Avoid very thin pasta like angel hair — it gets lost in a sauce this heavy.
How do I keep the sauce from getting gluey when I toss in the pasta?
Add the pasta while the sauce is still loose and over low heat, and toss quickly. If it seizes up, a spoonful of reserved pasta water stirred in will bring it back to the right consistency.
Is there a way to make this less rich without changing the recipe too much?
Reduce the cream to three-quarters of a cup and add a quarter cup of pasta water in its place. The sauce will be slightly less thick but still coats the pasta well, and the overall dish feels a bit lighter.
Can I make a larger batch and portion it out for multiple meals?
Yes, and it scales up cleanly — just use a wider pan so the shrimp sear rather than steam. Store portions in individual airtight containers so you can reheat one serving at a time without repeatedly warming the whole batch.
