Ingredients
Method
- Cook the spaghetti in salted boiling water according to package directions. Reserve 1/4 cup pasta water before draining.
- While the pasta cooks, melt the butter in a large skillet over medium-high heat.
- Add the shrimp in a single layer. Season with salt, pepper, and red pepper flakes. Cook 2 minutes per side until pink and curled. Remove and set aside.
- Add the garlic to the same pan and cook for 30 seconds until fragrant.
- Pour in the lemon juice and pasta water. Let it simmer for 1 minute, scraping up any brown bits.
- Add the drained pasta to the skillet and toss to coat in the sauce. Add the lemon zest.
- Return the shrimp to the pan and toss everything together.
- Serve immediately with fresh parsley and grated Parmesan.
Notes
Don't overcook the shrimp — they continue cooking in the residual heat of the pasta. Pasta water is the secret ingredient here. The starch helps the sauce cling to the noodles perfectly. Angel hair works great too if you want an even faster cook time.
