These comforting meatball subs feature tender, juicy meatballs in a flavorful homemade marinara sauce topped with melted mozzarella, all served in a sturdy hoagie roll. Perfect for a quick, satisfying weeknight meal or casual gatherings.
Do not overmix the meatball mixture to keep meatballs tender. Use fresh garlic for best flavor. Toast rolls lightly to prevent sogginess. Broil cheese carefully to avoid burning. Meatballs can be made ahead and frozen before baking; add extra cooking time if baking from frozen.
