1. Cook the pasta following the packaging instructions for al dente pasta. Drain and set aside.
2. Add the cottage cheese, skim milk, and Parmesan to a high-speed blender or food processor. Blend on high speed until creamy, thick, and smooth. Set aside.
3. In a medium saucepan over medium heat, add olive oil and sauté the garlic until fragrant (about 30 seconds to 1 minute).
4. Pour the blended cottage cheese mixture into the saucepan and bring to a gentle simmer. The sauce will thin out quickly, which is normal. Reduce to low heat.
5. In a small bowl, whisk cornstarch with cold water. Whisk in the warm sauce and cook until the cottage cheese sauce thickens.
6. Stir in the cooked pasta and cook for a few extra minutes until warm and coated with the sauce.
7. Serve with freshly chopped parsley over any pasta you love.
