Following the directions on the pasta box, start to cook the pasta. When done, reserve 1 cup of the pasta water and set aside.

In a large sauté pan over medium heat, add the butter and olive oil, and stir to combine and warm. Add the shrimp to the pan and cook until done, for about 2 minutes a side. Don’t over cook. Turn off heat and set aside.

Transfer the cooked pasta to a warm bowl. Add the pesto and gently toss to coat completely. In the same bowl, add the shrimp, including all the sauce from the pan and gently toss. Add ½ cup of the reserved pasta water or more if needed, and half of the parmesan cheese to the pasta, tossing to coat evenly. Top with the rest of the parmesan, red pepper flakes and torn basil. Serve and Enjoy!
