Step 1

Bring a large pot of salted water to a boil and cook the pasta until al dente, according to package instructions. Reserve 1 cup of the pasta water. Use a colander to drain the pasta. Return to pot or place in a large serving bowl.

Step 2

In a blender or food processor, combine the pesto, cottage cheese, and 1/2 cup of reserved pasta water. Blend until smooth. Season with salt and pepper, to taste.

Step 3

Add the creamy pesto sauce to the pasta and stir until pasta is well coated. Garnish with crushed red pepper flakes, fresh basil, and Parmesan cheese, if desired. Serve warm.
