Ingredients
Method
- **Boil.** Cook spaghetti in heavily salted water until al dente. Reserve 1 cup pasta water, then drain.
- **Sear shrimp.** Heat 2 tbsp butter and olive oil in a large skillet over medium high heat. Pat shrimp dry, season with salt and pepper, and sear 90 seconds per side. Transfer to a plate.
- **Sauce.** Reduce heat to medium. Add remaining butter, garlic, and red pepper flakes. Cook 1 minute until fragrant.
- **Deglaze.** Pour in white wine (if using), lemon juice, and 1/2 cup pasta water. Simmer 2 minutes.
- **Combine.** Add spaghetti and shrimp back to the pan. Toss with lemon zest and parmesan, adding more pasta water as needed to make a silky sauce.
- **Serve.** Sprinkle with parsley and extra parmesan. Serve immediately.
Notes
Use fresh shrimp or properly thawed frozen shrimp. Partially frozen shrimp release water and prevent browning. Save 1 cup of pasta water before draining. Do not forget. It is the secret to silky sauce. Store leftovers in an airtight container in the fridge for up to 2 days.
