Made with simple ingredients and ready in under an hour, these meatball marinara subs feature juicy beef meatballs in toasted sub buns with lots of marinara and rich mozzarella cheese.
Preheat oven to 400F and lightly grease a medium sheet pan.
In a large bowl, combine ground beef, breadcrumbs, egg, garlic, salt, and pepper. Scoop mixture into 1-in meatballs and place on prepared sheet pan.
Evenly pour marinara sauce over meatballs and bake at 400F 25-30 minutes until meatballs register 165F.
Cut sub buns about 3/4th of the way, fanning open and arrange in a 9x13 baking dish. Brush inside of buns with melted butter and sprinkle with garlic powder. Broil buns under high 1-2 minutes until lightly toasted.
Spoon about 3 meatballs and some marinara sauce into each toasted bun. Top meatballs with mozzarella and Parmesan.
Broil meatball subs under high 2-3 minutes until cheese is melted and lightly browned. Top meatball subs with basil and serve immediately while warm. Enjoy!
