How to Make Cheesiest Meatball Sub Bombs Recipe
Step 1: Prepare the Meatballs
Start by preheating your oven to 375 degrees Fahrenheit and line a baking sheet with parchment paper to keep things mess-free and easy. In a large bowl, combine the ground beef, breadcrumbs, Parmesan cheese, egg, minced garlic, Italian seasoning, salt, and black pepper. Mix just until everything comes together—over-mixing can make the meatballs tough. Then roll the mixture into 12 evenly sized meatballs for consistent cooking.
Step 2: Bake the Meatballs
Place your meatballs on the lined baking sheet, spacing them apart so they cook evenly. Pop them in the oven for about 15 to 20 minutes until they are fully cooked through and have a gorgeous golden brown finish on the outside, which adds a beautiful texture contrast to the soft inside.
Step 3: Assemble the Subs
While the meatballs bake, slice your sub rolls horizontally—but only halfway through, so the sub stays intact. Spoon a generous layer of marinara sauce on the bottom halves of each roll. Place 2 warm meatballs inside each sub, then pile on the shredded mozzarella and provolone cheeses evenly over the top of the meatballs. This layering sets the stage for cheese-filled bliss.
Step 4: Melt the Cheese
Return your assembled subs to a baking sheet and place them back into the oven for another 5 to 7 minutes. This step is the magic moment when the cheeses melt into gooey, bubbly perfection that cradles the meatballs, making this the ultimate Cheesiest Meatball Sub Bombs Recipe experience.
Step 5: Garnish and Serve
Once your subs come out of the oven, sprinkle the fresh chopped parsley over the top for a pop of color and a fresh herbal note that balances the rich flavors beautifully. Now, they’re ready to enjoy immediately, piping hot and oozing cheesy goodness.
How to Serve Cheesiest Meatball Sub Bombs Recipe

Garnishes
Adding chopped fresh parsley is a simple yet effective way to brighten the subs. For additional flair, you might sprinkle a little extra grated Parmesan or a few red pepper flakes for heat, depending on your mood. These little touches can bring a fresh or spicy dimension to your already spectacular dish.
Side Dishes
This recipe pairs wonderfully with classic sides like crispy garlic bread or a crisp green salad tossed with a tangy vinaigrette. A side of roasted veggies also complements the richness of the meatball subs and rounds out your meal perfectly.
Creative Ways to Present
Feeling fancy? Cut the subs into smaller sliders for a party platter that invites sharing and lets guests try multiple bites. You could also serve the meatballs on toasted baguette slices and drizzle with extra marinara for an informal appetizer-style presentation that’s sure to be a hit.
Make Ahead and Storage
Storing Leftovers
If you have any subs left over, wrap them tightly in foil or plastic wrap and store in the fridge for up to 2 days. This helps keep the bread from drying out while maintaining the delightful flavors and textures.
Freezing
To freeze for longer storage, assemble the subs without baking the cheese step, then wrap each sub tightly in plastic wrap and aluminum foil. Freeze for up to 3 months. When ready to eat, thaw overnight in the fridge before baking to melt the cheese.
Reheating
The best way to reheat these glorious subs is in the oven at 350 degrees Fahrenheit wrapped in foil to keep everything moist and to re-melt the cheese evenly—usually for about 10-15 minutes. Microwaving is possible but may result in soggy bread and unevenly melted cheese.
FAQs
Can I make the meatballs ahead of time?
Absolutely! You can prepare and bake the meatballs a day ahead, then assemble and finish baking the subs just before serving. This makes entertaining a breeze.
What if I want a lighter version of this recipe?
Swap out the ground beef for ground turkey or chicken to lighten the fat content without sacrificing flavor. The cheeses and marinara will still give you plenty of richness.
Can I add extra vegetables to the subs?
Yes! Sautéed onions, bell peppers, or mushrooms are fantastic additions. Just add them inside the sub before the final bake for an extra layer of taste and texture.
Is this recipe gluten-free?
The classic recipe uses regular sub rolls and breadcrumbs, so it’s not gluten-free. But you can use gluten-free bread and gluten-free breadcrumbs to adapt it.
How spicy is this recipe?
The Cheesiest Meatball Sub Bombs Recipe has a mild flavor profile, focusing on cheese and Italian seasonings. You can spice it up by adding crushed red pepper flakes to the marinara or meatball mix.
