Creating Creamy Shrimp Scampi Pasta is straightforward if you follow these simple steps:

1. Cook the Pasta: In a large pot of salted boiling water, cook the linguine or spaghetti according to package instructions until al dente. Drain and set aside, reserving about ½ cup of pasta water.

2. Sauté the Shrimp: In a large skillet, heat 2 tablespoons of butter and 2 tablespoons of olive oil over medium heat. Add the shrimp and season with salt and pepper. Cook for 2-3 minutes on each side until they turn pink and opaque. Remove the shrimp from the skillet and set aside.

3. Prepare the Sauce: In the same skillet, add the remaining butter and olive oil. Stir in the minced garlic and red pepper flakes (if using). Sauté for about 1 minute until fragrant, being careful not to burn the garlic.

4. Add Liquids: Pour in the chicken broth and bring to a simmer. Let it cook for about 2 minutes to reduce slightly.

5. Make it Creamy: Stir in the heavy cream, lemon juice, and lemon zest. Allow the sauce to simmer for another 3-5 minutes until it thickens slightly.

6. Combine Pasta and Shrimp: Add the cooked pasta and sautéed shrimp back into the skillet. Toss everything together to coat the pasta evenly in the sauce.

7. Finish with Cheese: Stir in the grated Parmesan cheese and mix until melted and combined. If the sauce is too thick, add some reserved pasta water to reach your desired consistency.

8. Season to Taste: Taste the dish and adjust seasoning with salt and pepper as needed.

9. Garnish: Remove from heat and garnish with chopped fresh parsley.

10. Serve: Plate the Creamy Shrimp Scampi Pasta and enjoy immediately!
