In a blender, blend cottage cheese, milk, Parmesan, garlic powder, nutmeg, and pepper until smooth. Set aside. The mixture will have a liquid consistency but will thicken when it cooks.
Fill a saucepan with water and bring to a boil. Cook the pasta according to package instructions. Remove from the saucepan and strain.
Pour the sauce into a large skillet over low heat. Heat the sauce 2 to 3 minutes then add the cooked pasta and dried parsley, tossing to combine. Taste and add salt if needed. Some cottage cheese brands are saltier than others
Serve hot with the chopped fresh parsley and more Parmesan as desired on top.
Notes
Heat the Alfredo sauce over low heat to avoid curdling it.
The sauce will thicken as it cooks, so don’t try to thicken the blended sauce even if it appears too thin to you.
Store leftovers in the refrigerator for 3-4 days, but they do not freeze well.
