  1. Preheat oven to 400 degrees F (200 degrees C). Spray a 9x13-inch baking dish with cooking spray.

  4. Pour tomatoes, 3/4 cup Parmesan cheese, oregano, basil, garlic, and salt over spaghetti squash; mix well. Sprinkle remaining 1/4 cup Parmesan cheese on top.
  5. Bake in the preheated oven until golden and bubbly, 45 to 60 minutes.
