1Add the cottage cheese, hard-boiled eggs, Parmesan, milk, cornstarch, garlic powder, Italian seasoning, salt, and pepper to a blender and blend until completely smooth and creamy.
2Pour the sauce into a skillet or saucepan over medium-low heat and cook, stirring frequently, until warmed through and slightly thickened, taking care not to let it boil.
3Toss the sauce with freshly cooked pasta, adding a splash of reserved pasta water if needed to loosen the sauce. Garnish with fresh parsley and extra Parmesan before serving.
