Preheat the oven to 425 degrees F (220 degrees C). Lightly grease a rimmed baking sheet with olive oil.
Cook meat in large skillet over medium-high heat until fat is rendered and meat is brown and crumbled. Add onion, ½ teaspoon salt, ¼ teaspoon pepper and ¼ teaspoon garlic powder, and cook until softened.
Stir in sauce and bring to a simmer. Simmer for 10 minutes.
Meanwhile, bring a large pot of salted water to a boil, and cook pasta until tender with a bite, according to package directions. Drain and stir pasta into sauce. Spread mixture onto prepared baking sheet.
Stir cottage cheese and 1 cup Italian cheese together with remaining salt, pepper, and garlic powder. Dollop cheese mixture over pasta mixture and spread remaining Italian cheese over the top.
Bake in the preheated oven until bubbly and lightly browned and crisp around the edges, 20 to 25 minutes.
