The Complete Garlic Bread Meatball Subs Recipe

This recipe makes 4 large subs. It can easily be doubled.

Ingredients – For the Meatballs:

1 lb (450g) ground beef (80/20 for juicy meatballs)

½ lb (225g) ground pork (or use all beef)

½ cup (50g) plain breadcrumbs (or panko)

¼ cup (60ml) milk

1 large egg

¼ cup (25g) grated Parmesan cheese

2 cloves garlic, minced

1 teaspoon dried oregano

1 teaspoon dried basil

½ teaspoon salt

¼ teaspoon black pepper

2 tablespoons olive oil (for searing)

2 cups (480ml) marinara sauce (homemade or store‑bought)

Ingredients – For the Garlic Butter Rolls:

4 hoagie rolls or sub rolls (soft, sturdy rolls)

½ cup (113g, 1 stick) unsalted butter, softened

4 cloves garlic, minced (or 1 tablespoon garlic paste)

2 tablespoons fresh parsley, finely chopped

¼ teaspoon salt

Optional: ¼ teaspoon red pepper flakes

For Assembling:

2 cups (8 oz / 226g) shredded mozzarella cheese

¼ cup (25g) grated Parmesan cheese

Fresh basil or parsley for garnish

Equipment:

• Large baking sheet
• Large skillet or Dutch oven
• Mixing bowl
• Cookie scoop or spoon
• Aluminum foil

Step‑by‑Step Instructions

Step 1 – Make the Meatballs

In a large bowl, combine the breadcrumbs and milk. Let sit for 5 minutes until the breadcrumbs absorb the milk. Add the ground beef, ground pork, egg, Parmesan cheese, minced garlic, oregano, basil, salt, and pepper. Mix gently with your hands until just combined – do not overmix, or the meatballs will be tough. Roll the mixture into 1.5‑inch meatballs (about 16‑20 meatballs).

Step 2 – Sear the Meatballs

Heat the olive oil in a large skillet or Dutch oven over medium‑high heat. Add the meatballs in a single layer (work in batches if needed). Sear for 2‑3 minutes per side, until browned on all sides. The meatballs do not need to be cooked through at this stage – they will finish cooking in the sauce.

Step 3 – Simmer in Marinara Sauce

Pour the marinara sauce over the meatballs, stirring gently to coat. Reduce heat to low, cover, and simmer for 15‑20 minutes, until the meatballs are cooked through (internal temperature 165°F / 74°C). Stir occasionally. While the meatballs simmer, prepare the garlic butter rolls.

Step 4 – Make the Garlic Butter Spread

In a small bowl, combine the softened butter, minced garlic, fresh parsley, salt, and red pepper flakes (if using). Mix until smooth and well combined. The garlic butter can be made ahead and stored in the refrigerator.

Step 5 – Toast the Garlic Butter Rolls

Preheat your oven to 400°F (200°C). Split the hoagie rolls open lengthwise, leaving them hinged (or cut all the way through if you prefer). Spread the cut sides generously with the garlic butter mixture. Place the rolls cut‑side up on a baking sheet. Toast for 5‑7 minutes, until the edges are golden and the butter is bubbly. If you want extra crispiness, you can also toast them under the broiler for 1‑2 minutes – watch carefully.

Step 6 – Assemble the Subs

Remove the toasted rolls from the oven. Place the bottom halves on a clean baking sheet or directly on serving plates. Spoon a layer of marinara sauce onto the bottom of each roll. Arrange 4‑5 meatballs on each sub (depending on size). Top with more marinara sauce, then generously sprinkle with mozzarella and Parmesan cheese. Place the top halves of the rolls over the cheese (or leave open‑faced).

Step 7 – Melt the Cheese

Return the assembled subs to the oven (or place under the broiler) for 2‑3 minutes, until the cheese is melted and bubbly. If using the broiler, watch carefully to prevent burning.

Step 8 – Serve

Garnish with fresh basil or parsley. Serve hot, with extra marinara sauce on the side for dipping. These garlic bread meatball heroes are messy, decadent, and absolutely delicious.

Pro Tips for the Best Garlic Bread Meatball Subs

Follow these expert tips for perfect meatball subs on garlic bread every time:

Use a combination of beef and pork – Pork adds moisture and flavor. If you use all beef, choose 80/20 ground chuck for juiciness.

Do not overmix the meatball mixture – Overmixing develops tough proteins. Mix gently until just combined.

Sear the meatballs for deep flavor – The browning creates a flavorful crust that adds complexity to the sauce.

Use a good quality marinara sauce – The sauce is a key component. Use your favorite jarred sauce or make homemade.

Do not skip toasting the rolls – Toasting with garlic butter creates a barrier that prevents the bread from getting soggy, and adds incredible flavor.

Use fresh mozzarella for extra gooeyness – Fresh mozzarella melts beautifully. Low‑moisture mozzarella also works well and browns nicely.

Serve immediately – These subs are best hot out of the oven. The bread will soften over time, so enjoy them right away.
