Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions (usually 8-10 minutes). Drain and reserve 1 cup of pasta water.

Step 2: Sauté the Shrimp
In a large skillet, heat the olive oil over medium-high heat. Season the shrimp with salt and pepper. Add the shrimp to the skillet and cook for 2-3 minutes per side, until pink and opaque. Remove from the skillet and set aside.

Step 3: Make the Creamy Garlic Sauce
In the same skillet, melt the butter over medium heat. Add the minced garlic and cook for 1-2 minutes until fragrant, being careful not to burn the garlic. Pour in the heavy cream and bring it to a simmer. Let it cook for 3-4 minutes until it thickens slightly.

Step 4: Add the Parmesan and Season
Stir in the grated Parmesan cheese, salt, and pepper. If you prefer a spicy kick, add red pepper flakes. Stir until the sauce is smooth and creamy.

Step 5: Combine Pasta and Shrimp
Add the cooked pasta to the skillet, tossing it in the sauce to coat evenly. If the sauce is too thick, add a little reserved pasta water to thin it to your desired consistency. Add the cooked shrimp back into the skillet and toss to combine.

Step 6: Serve and Garnish
Serve the pasta hot, garnished with fresh chopped parsley and an optional extra sprinkle of Parmesan cheese.
