Tortellini Alfredo with Shrimp

Thaw frozen shrimp in a colander by running cold water over them.

Heat 1 teaspoon butter in a skillet over medium-high heat. Saute shrimp until they are bright pink on the outside and the meat is opaque, 3 to 4 minutes, making sure not to overcook.

Combine remaining butter, heavy cream, cream cheese, and leek in a saucepan over medium heat. Let simmer until melted and mixed well, about 5 minutes. Stir in Parmesan cheese, garlic powder, salt, and pepper. Let Alfredo sauce simmer over low heat for 15 to 20 minutes. Add tortellini and heat through, about 5 minutes. Toss shrimp into the sauce, coating well. Top with parsley and serve.
