Ingredients

  • Torpedo rolls: Sub rolls for their sturdy and crispy texture, perfect for holding all the toppings
  • Cooking spray: Use a canola oil spray to ensure golden and crisp bread without excess grease
  • Softened butter: For spreading over the rolls and pairing beautifully with the garlic
  • Minced garlic: Fresh garlic adds bold flavor to the rolls
  • Shredded mozzarella cheese: Melts beautifully and adds creaminess with a slight stretch
  • Your favorite pasta sauce: The base for coating the meatballs, choose one with a flavor you love
  • Frozen meatballs: A major time saver that still delivers delicious results

How To Make Garlic Bread Meatball Subs

Cook the Meatballs:
Place frozen meatballs in your slow cooker. Pour your favorite pasta sauce evenly over the top. Cook on high for 2 hours, stirring occasionally to ensure even heating.
Preheat the Oven:
Set your oven to 400°F or 200°C. Line a shallow baking sheet with foil for easy cleanup and spray lightly with cooking spray.
Make Garlic Butter:
In a small bowl, combine softened butter with minced garlic until smooth. This will ensure every bite of bread is packed with flavor.
Prepare the Rolls:
Carefully slice each torpedo roll open lengthwise. Spread a generous amount of garlic butter on the inside of each roll. Arrange them on the prepared baking sheet and give the tops a light spray of cooking oil.
Toast the Bread:
Bake the rolls in the oven for about 5 minutes or until lightly toasted. This step gives the bread structure and added crunch.
Assemble the Subs:
Remove toasted rolls from the oven. Fill each with several warm meatballs, spoon enough sauce over the meatballs for flavor, and sprinkle shredded mozzarella generously on top. For extra indulgence, add more sauce and cheese if desired.
Melt the Cheese:
Place the subs back into the oven and bake for about 3-5 minutes, until the cheese is perfectly melted, bubbly, and tempting.
Serve:
Serve your hot meatball subs on a platter, paired with extra sauce for dipping if you like. Enjoy every cheesy, garlicky bite.

Mozzarella is my favorite ingredient to use here because not only does it melt like a dream, but its creamy flavor complements the garlic-spiked bread and saucy meatballs so well. My kids even like sprinkling extra cheese on their plates to dip pieces of bread into.

Storage Tips

If you have leftovers, keep the bread and meatballs separate. Store meatballs with sauce in an airtight container in the refrigerator for up to 3 days. The rolls are best enjoyed the day they are made, but they can be toasted again for a quick refresh.

Ingredient Substitutions

No mozzarella? Use provolone cheese for a slightly sharper flavor. If you are out of sub rolls, French bread works wonderfully.

Serving Suggestions

Pair with a fresh green salad or roasted vegetables for a balanced meal. If you want something extra indulgent, consider serving alongside crispy seasoned fries.
