Bring a large pot of salted water to a boil. Cook the pasta according to the package directions until it is al dente.

Before draining the pasta, reserve about half a cup of the starchy pasta water. Drain the rest and set the pasta aside.

In a high-speed blender or food processor, combine the cottage cheese, parmesan cheese, minced garlic, milk, salt, black pepper, and onion powder.

Blend on high speed until the mixture is completely smooth and creamy. There should be no lumps remaining.

Place the empty pasta pot back on the stove over low heat. Add the cooked pasta back into the pot.

Pour the blended cottage cheese sauce over the pasta. Toss gently with tongs or a spoon to coat every piece.

If the sauce seems too thick, add a tablespoon or two of the reserved pasta water and stir until you reach your desired consistency.

Heat the pasta for just 1 to 2 minutes until the sauce is warm. Do not let it boil, or the cheese may separate.

Serve immediately with a sprinkle of fresh parsley or extra parmesan cheese.
