Bring a large pot of salted water to a boil over high heat. Once boiling, add 8 ounces of your preferred pasta and cook according to package instructions until al dente, typically 9-11 minutes. When done, reserve ½ cup of pasta water in a bowl and then drain the pasta, setting it aside while you prepare the rest of the dish.

In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Season 1 pound of large, peeled, and deveined shrimp with 1 teaspoon of salt, ½ teaspoon of black pepper, and optional ¼ teaspoon of red pepper flakes. Add the shrimp to the skillet, cooking for 1-2 minutes on each side until they're pink and opaque. Remove the shrimp from the skillet and set aside, leaving the flavorful oil behind.

Using the same skillet, add the trimmed and cut asparagus and sauté over medium heat for 3-4 minutes. Stir frequently until the asparagus is bright green and tender-crisp, achieving a vibrant color and texture that complements the shrimp beautifully.

Return the sautéed shrimp to the skillet with the asparagus, and add the drained pasta you prepared earlier. Toss everything together gently, ensuring that the shrimp and asparagus are evenly distributed throughout the pasta.

Stir in 1 cup of basil pesto into the pasta mixture, combining thoroughly. Pour in a splash of the reserved pasta water to help create a creamy coating that binds the pesto to the pasta.

Mix in ½ cup of grated Parmesan cheese and, if you like, 1 teaspoon of lemon zest to brighten the dish. Stir until the cheese is melted and distributed evenly.

Spoon your delicious Creamy Pesto Shrimp Asparagus Pasta onto warm plates. Optionally, top with extra Parmesan cheese and freshly cracked black pepper for an added touch of flavor.
