Introduction
Few sandwiches are as satisfying as a hot, cheesy meatball sub. Juicy homemade meatballs are simmered in rich marinara sauce, tucked into toasted sub rolls, and covered with melted mozzarella and Parmesan. The result is a warm, saucy sandwich with crispy edges, tender meatballs, and plenty of cheesy goodness.
This recipe is simple enough for a weeknight meal but hearty enough for game day, parties, or a casual weekend dinner.
Ingredients
For the Meatballs
- 1 pound ground beef
- ½ cup breadcrumbs
- ¼ cup grated Parmesan cheese
- 1 large egg
- 2 cloves garlic, minced
- 1 teaspoon Italian seasoning
- ½ teaspoon salt
- ½ teaspoon black pepper
- 2 tablespoons finely chopped fresh parsley
- 2 tablespoons milk
For the Sandwiches
- 4–6 sub rolls or hoagie rolls
- 2 cups marinara sauce
- 1 ½ cups shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
- 2 tablespoons butter, softened
- 1 clove garlic, minced
- 1 tablespoon chopped parsley, optional
- 1 tablespoon olive oil, for cooking
Instructions
1. Make the Meatballs
Preheat the oven to 400°F (200°C).
In a large bowl, combine the ground beef, breadcrumbs, Parmesan, egg, garlic, Italian seasoning, salt, pepper, parsley, and milk.
Mix gently with your hands until everything is evenly combined. Avoid overmixing, as this can make the meatballs tough.
Shape the mixture into small meatballs, about 1½ inches in diameter.
2. Cook the Meatballs
Heat the olive oil in a large oven-safe skillet over medium-high heat.
Add the meatballs and brown them on several sides for about 5–7 minutes.
Transfer the skillet to the oven and bake for approximately 10–12 minutes, or until the meatballs are cooked through.
Alternatively, you can bake the meatballs on a lined baking sheet for about 15–18 minutes.
3. Simmer in Marinara Sauce
Transfer the cooked meatballs to a saucepan and pour in the marinara sauce.
Bring the sauce to a gentle simmer and cook for 10–15 minutes, allowing the meatballs to absorb some of the sauce and become extra flavorful.
4. Prepare the Rolls
Preheat the oven to 400°F (200°C).
Slice the sub rolls lengthwise, being careful not to cut completely through them.
Mix the softened butter with minced garlic and parsley.
Spread the garlic butter lightly over the inside of each roll.
Place the rolls on a baking sheet and toast for about 3–5 minutes, just until lightly crisp.
5. Assemble the Sandwiches
Place 3–4 meatballs inside each toasted roll, depending on their size.
Spoon plenty of marinara sauce over the meatballs.
Sprinkle generously with shredded mozzarella and Parmesan.
6. Melt the Cheese
Return the assembled sandwiches to the oven.
Bake for about 5–7 minutes, or until the cheese has melted completely.
For a beautifully browned top, switch to the broiler for the final 1–2 minutes, watching carefully so the bread doesn’t burn.
Serve immediately while hot.
Tips for the Best Meatball Subs
- Don’t overmix the meatball mixture. Gentle mixing keeps the meatballs tender.
- Brown the meatballs first. This adds extra flavor and gives them a delicious outer crust.
- Toast the bread lightly. It helps prevent the roll from becoming soggy from the sauce.
- Use plenty of sauce. The marinara brings all the flavors together.
- Choose sturdy rolls. A good hoagie or Italian-style roll holds the meatballs much better than soft sandwich bread.
- Broil carefully. The cheese can go from perfectly golden to burnt very quickly.
Variations
Italian Sausage Meatball Subs
Replace half of the ground beef with Italian sausage for a richer, more flavorful meatball.
Spicy Meatball Subs
Add crushed red pepper flakes to the meatball mixture or marinara sauce.
Extra Cheesy Subs
Add provolone, Parmesan, and mozzarella for an especially cheesy sandwich.
Chicken Meatball Subs
Use ground chicken instead of beef for a lighter alternative.
Mushroom Meatball Subs
Sauté sliced mushrooms with garlic and add them underneath the meatballs before topping with cheese.
Make-Ahead Option
The meatballs can be prepared and cooked up to 2 days ahead. Store them in an airtight container with the marinara sauce in the refrigerator.
When you’re ready to make the sandwiches, simply reheat the meatballs and sauce, then assemble and toast the subs.
Storage and Reheating
Store leftover meatballs and sauce separately from the bread whenever possible.
Refrigerate for up to 3–4 days.
For best results, reheat the meatballs and sauce in a saucepan over medium-low heat. Toast fresh rolls and assemble the sandwiches just before serving.
What to Serve With Meatball Subs
These sandwiches pair especially well with:
- Crispy French fries
- Potato wedges
- Coleslaw
- Caesar salad
- Italian green salad
- Roasted vegetables
- Garlic bread
