01 - Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve 1/2 cup pasta water, then drain.
02 - Pat shrimp dry and toss with salt, black pepper, and red pepper flakes.
03 - In a large skillet, heat 1 tbsp butter and 1 tbsp olive oil over medium-high heat. Add shrimp and cook 1–2 minutes per side until pink and just cooked through. Remove shrimp to a plate and set aside.
04 - Lower heat to medium. Add remaining butter and olive oil to skillet. Sauté garlic for 30 seconds until fragrant.
05 - Stir in lemon zest, lemon juice, and wine (or broth). Simmer for 2 minutes, scraping up any browned bits.
06 - Return shrimp (and any juices) to the skillet. Add drained pasta and toss well to coat, adding reserved pasta water a little at a time until the sauce is silky. Stir in parsley. Taste and adjust seasoning as needed.
