Cook the Pasta: Boil pasta according to package instructions until al dente. Drain and set aside.
Prepare Shrimp: In a large skillet, heat olive oil and 1 tablespoon of butter over medium-high heat. Add shrimp, season with salt and pepper, and cook until pink and opaque (about 2-3 minutes per side). Remove shrimp and set aside.
Make Garlic Butter Sauce: In the same skillet, add the remaining butter and minced garlic. Sauté until fragrant, about 1 minute. Add lemon juice and zest, stirring well.
Combine Ingredients: Add the pasta and shrimp to the skillet, tossing to coat with the sauce. Season with more salt, pepper, and parsley.
Serve: Garnish with parsley and serve immediately.
