Indulge in a plate full of linguine and prawns bathed in garlicky Parmesan cream sauce for dinner tonight. Sprinkle with extra cheese and lemon zest to brighten it up.
Bring a large pot of water to a boil. Add 1 tablespoon salt and the pasta; cook until al dente, according to package directions. Reserve 3/4 cup cooking water, then drain pasta.
Heat a large straight-sided skillet over high heat. Add butter and let melt. Add shrimp and garlic, season with salt and lemon zest, and cook until just opaque, 2 to 3 minutes. Remove shrimp from pan, leaving garlic. Add cream and simmer on medium for 5 minutes.
Remove garlic cloves. Stir in drained pasta and cheese. Mix in pasta water to achieve a creamy consistency, then season with salt, pepper, and lemon juice. Add shrimp and serve sprinkled with cheese and lemon zest.
