Step 1: Prepare the Pasta

1. In a large pot, bring salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Drain and set aside, reserving 1/4 cup of pasta water for later use if needed.
2. Drizzle 2 tablespoons of olive oil over the cooked pasta to prevent sticking and set aside.

Step 2: Cook the Shrimp

1. Pat the shrimp dry with paper towels, then season with salt, pepper, paprika, and red pepper flakes.
2. In a large skillet, heat 2 tablespoons of olive oil and 2 tablespoons of butter over medium-high heat.
3. Add the minced garlic and sauté for about 1 minute until fragrant.
4. Add the seasoned shrimp to the skillet in a single layer. Cook for 2-3 minutes per side or until the shrimp turn pink and opaque.
5. Remove the shrimp from the skillet and set them aside on a plate.

Step 3: Prepare the Garlic Lemon Butter Sauce

1. In the same skillet, add the remaining 4 tablespoons of butter. Allow it to melt over medium heat.
2. Add 3 cloves of minced garlic and sauté until fragrant, about 1 minute.
3. Pour in the white wine (or chicken broth) and lemon juice. Allow the sauce to simmer for 3-4 minutes, letting the alcohol evaporate if using wine.
4. If you want a creamy sauce, stir in the heavy cream at this point and let it heat for another 2 minutes.
5. Add the reserved pasta water a tablespoon at a time if the sauce needs more moisture. Season with salt and pepper to taste.

Step 4: Combine the Pasta and Shrimp

1. Add the cooked pasta to the skillet, tossing it in the garlic lemon butter sauce to coat evenly.
2. Add the cooked shrimp back to the skillet along with the lemon zest and chopped parsley.
3. Toss everything together gently for about 2 minutes until well combined. Sprinkle with grated Parmesan cheese if desired.

Step 5: Serve

1. Transfer the Garlic Butter Shrimp Pasta to a large serving dish.
2. Garnish with extra parsley, lemon wedges, and a sprinkle of Parmesan cheese.
3. Serve immediately and enjoy a restaurant-quality dish at home.
