Meatball Marinara Subs are hearty, cheesy, and loaded with flavor—featuring juicy meatballs simmered in marinara, nestled in toasted sub rolls, and topped with melty mozzarella. Perfect for an easy dinner or game day crowd-pleaser.

Ingredients

  • 1 lb ground beef (or beef/pork blend)
  • 1/2 cup breadcrumbs
  • 1 egg
  • 1/4 cup grated Parmesan cheese
  • 2 cloves garlic, minced
  • 1 tsp Italian seasoning
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 2 cups marinara sauce (store-bought or homemade)
  • 4 sub rolls or hoagie buns
  • 1 1/2 cups shredded mozzarella cheese
  • 12 tbsp butter or olive oil (for toasting rolls)
  • Optional: chopped fresh basil or parsley for garnish

Instructions

  1. Preheat oven to 375°F (190°C).
  2. In a large bowl, mix ground beef, breadcrumbs, egg, Parmesan, garlic, Italian seasoning, salt, and pepper until just combined.
  3. Form into 1½-inch meatballs and place on a baking sheet.
  4. Bake for 18–20 minutes, or until browned and cooked through.
  5. Meanwhile, warm marinara sauce in a saucepan over medium heat.
  6. Add cooked meatballs to the sauce and simmer for 10 minutes to blend flavors.
  7. Slice sub rolls and lightly toast with butter or olive oil in the oven or a skillet until golden.
  8. Fill each roll with 3–4 meatballs and spoon extra marinara over top.
  9. Sprinkle shredded mozzarella over each sub and return to oven for 5–7 minutes, until cheese is melted and bubbly.
  10. Garnish with basil or parsley if desired and serve hot.

Notes

  • Use frozen meatballs and jarred sauce for a quick version.
  • Toast rolls before assembling to prevent sogginess.
  • Try provolone or a cheese blend for added flavor.
  • Meatballs and sauce can be made ahead or frozen.
