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 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. Serve immediately, garnished with lemon wedges and extra parsley.
