01 - Bring a large pot of salted water to a boil. Cook the angel hair pasta according to package instructions until al dente. Drain, reserving 1/2 cup of pasta water, and set aside.
02 - Pat the shrimp dry and season lightly with salt and pepper.
03 - In a large skillet over medium heat, melt 2 tablespoons of butter with the olive oil. Add the shrimp in a single layer and cook for 1–2 minutes per side until pink and opaque. Remove shrimp to a plate.
04 - In the same skillet, add the minced garlic and red pepper flakes. Sauté for 30 seconds until fragrant.
05 - Pour in the white wine or chicken broth, scraping up any browned bits from the bottom. Stir in the lemon zest and juice. Simmer for 2–3 minutes to reduce slightly.
06 - Return the shrimp to the skillet along with the cooked pasta. Add the remaining 2 tablespoons of butter and chopped parsley. Toss everything together, adding reserved pasta water as needed to create a silky sauce.
07 - Taste and adjust seasoning with additional salt and pepper if needed.
08 - Serve immediately, garnished with lemon wedges and extra parsley.
