Preheat oven to 500°F and grease an oven safe casserole dish.
In a large prep bowl, add ground beef, almond flour, onion powder, garlic powder, salt, basil, oregano, parmesan cheese and eggs. Mix with hands until completely incorporated.
Pinch a bite size amount of ground beef and roll it into a ball. Press on a flat surface to form a patty. Place a cube of the cut mozzarella sticks and wrap the beef around it, ensuring there are no gaps or crevices. Continue until all of the meatballs have been formed and place into your casserole dish.
Bake in the oven for 15 minutes. Then remove casserole dish and set your oven to broil.
Pour jar of marinara sauce over meatballs and sprinkle the top with shredded mozzarella. Place dish under the broiler until cheese has melted and browned (about 5 minutes).
Remove dish from oven and garnish with chopped Italian parsley.
