Cook spaghetti squash, remove seeds, and scrape out the "noodles" into a large baking dish.
In a large skillet, add ground meat and diced onion and cook until meat is browned and crumbly and onion is tender.
Add pasta sauce, salt, pepper, oregano, basil, and garlic. Mix well.
Mix in the cottage cheese if you are adding, or skip this step.
Add the sauce mixture to the squash and mix well.
Top with shredded cheese and bake at 375°F for 20-25 minutes until cheese is golden and bubbly.
Serve hot! Enjoy!
