    Instructions
    
                - Preheat oven to 400°F. Adjust the oven rack to the middle position and butter a casserole pan. Set aside.
 - Meanwhile, combine ground beef, keto breadcrumbs, parmesan, parsley, egg, garlic powder, onion powder, salt and black pepper in a large salad bowl. Then, add the sauteed onions and mix everything well to combine.
 - Use a small cookie scoop to form the meatballs all the same size. Place the meatballs in the prepared casserole dish.
 - Bake them for 15 to 20 minutes or until fully cooked. Remove the meatballs casserole from the oven and drain the grease.
 - Top with marinara sauce and shredded cheese.
 - Place the meatballs casserole back in the oven. Bake for an additional 5 minutes until the cheese has fully melted.
