  • ½ cup breadcrumbs
  • 1 large egg
  • ¼ cup grated onion

  • 1 teaspoon Italian seasoning

For the Sauce and Assembly

  • 2 cups marinara sauce
  • 4 hoagie or sub rolls

How to Make Cheesy Meatball Subs

This recipe is simple to follow and comes together in under an hour.

1. Prepare the Meatballs

Preheat your oven to 400°F (200°C).

In a large mixing bowl, combine:

  • ground meat
  • breadcrumbs
  • egg
  • grated onion
  • garlic
  • Italian seasoning
  • salt and pepper

Mix gently until just combined. Avoid overmixing, which can make the meatballs dense.

Roll the mixture into 1 to 1½-inch meatballs and place them on a parchment-lined baking sheet.

2. Cook the Meatballs

Bake the meatballs for 18–20 minutes, until browned and fully cooked.

Alternatively, you can cook them in a skillet over medium heat, turning occasionally until browned on all sides.

3. Simmer in Marinara Sauce

In a large saucepan, heat the marinara sauce over medium heat.

Add the cooked meatballs and let them simmer for 10–15 minutes, allowing the flavors to blend together beautifully.

4. Prepare the Rolls

Slice the hoagie rolls open without cutting all the way through.

For extra flavor, lightly brush the inside of the rolls with butter and toast them in the oven for 3–5 minutes until slightly crispy.

5. Assemble the Meatball Subs

Place several meatballs into each roll and spoon extra marinara sauce over the top.

Add shredded mozzarella and provolone cheese.

Place the sandwiches under the broiler for 2–3 minutes until the cheese melts and becomes bubbly.

Sprinkle with parmesan cheese and fresh herbs if desired.

6. Serve

Serve the meatball subs immediately while warm and cheesy.

They pair perfectly with your favorite sides.

Recipe FAQs

Can I freeze the meatballs?

Yes! Cooked meatballs freeze very well. Store them in an airtight container for up to 3 months.

Can I use ground turkey or chicken?

Absolutely. Ground turkey or chicken creates a lighter version of the recipe. Adding a small amount of olive oil helps keep the meatballs moist.

How do I prevent soggy rolls?

Toast the rolls before assembling and avoid adding too much sauce.

Broiling the assembled subs also helps crisp the bread.
