Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

1 large egg
1 cup breadcrumbs (fresh or panko)
2 cups marinara sauce
1 cup shredded mozzarella cheese
1/2 cup grated parmesan cheese
4 sub rolls, split and toasted
Fresh basil, chopped (for garnish)
1 lb ground beef or a mix of beef and pork (optional addition if making homemade meatballs)
Salt and pepper to taste
1 tsp garlic powder
1 tsp Italian seasoning

Directions

Preheat oven to 375°F (190°C).
In a mixing bowl, combine ground meat (if using), egg, breadcrumbs, garlic powder, Italian seasoning, salt, and pepper. Mix until just combined—do not overwork.
Form the mixture into 12–15 small meatballs and place them on a baking sheet.
Bake the meatballs for 20 minutes or until fully cooked and golden brown.
Meanwhile, warm the marinara sauce in a saucepan over medium heat. Add the baked meatballs and simmer for 5–10 minutes to absorb the sauce.
Open each toasted sub roll and place 3–4 meatballs inside. Spoon additional marinara over the meatballs.
Sprinkle mozzarella and parmesan over the top of each sandwich.
Place the sandwiches under a broiler for 2–3 minutes, just until the cheese is melted and bubbling.
Garnish with freshly chopped basil and serve immediately.

Variations

Make it spicy: Add crushed red pepper flakes to the meat mixture or the marinara for a kick.

Garlic bread rolls: Brush the sub rolls with garlic butter before toasting for added richness.

Storage/Reheating

Storage: Store meatballs and sauce separately from the bread to prevent sogginess. Refrigerate in airtight containers for up to 3 days.

Reheating: Warm meatballs in a saucepan or microwave until hot. Assemble with fresh rolls and broil before serving.
