Preheat oven to 400°F.
Add tomatoes and garlic (cut side up) to a baking dish. Drizzle with olive oil and season with Italian seasoning, salt, and pepper.
Cover with foil and bake for 45 minutes, until the tomatoes burst and the garlic is soft.
Meanwhile, cook pasta according to package directions.
Blend the roasted tomatoes (and all their juices), garlic, and cottage cheese until silky smooth using a food processor or immersion blender.
Toss with the cooked pasta and finish with plenty of Parmesan and fresh parsley.
