Preparing shrimp scampi is a straightforward process. Follow these step-by-step instructions for a perfect dish:

1. Cook the Pasta: In a large pot of boiling salted water, cook the linguine or spaghetti according to package instructions until al dente. Drain and set aside, reserving a cup of pasta water.
2. Prepare the Shrimp: Season the shrimp with salt and pepper.
3. Heat the Oil and Butter: In a large skillet, heat the olive oil and 2 tablespoons of butter over medium heat.
4. Sauté the Garlic: Add the minced garlic and red pepper flakes to the skillet. Sauté for about 1 minute, or until fragrant, being careful not to burn the garlic.
5. Cook the Shrimp: Add the seasoned shrimp to the skillet. Cook for 2-3 minutes, turning occasionally, until they are pink and opaque.
6. Deglaze the Pan: Pour in the white wine or chicken broth and bring to a simmer. Let it cook for 2-3 minutes.
7. Add Lemon: Stir in the lemon juice and zest. If you want a richer sauce, add the remaining 2 tablespoons of butter and stir until melted.
8. Combine Pasta and Sauce: Toss the cooked pasta into the skillet, adding reserved pasta water little by little until desired consistency is reached.
9. Taste and Adjust: Season the dish with salt and pepper to taste.
10. Garnish and Serve: Remove from heat and garnish with fresh parsley. Serve immediately.

By following these steps, you’ll create a dish brimming with flavor and a fantastic presentation.
