Ingredients You’ll Need
Gathering simple, fresh ingredients is the key to making these mini meatball subs taste just right. Each component plays a crucial role, from the juicy meatballs to the creamy cheese and zesty marinara that brings everything together with vibrant color and flavor.
- 1 lb ground beef (or a mix of beef and pork): The base for tender, juicy meatballs with rich flavor.
- 1/2 cup breadcrumbs (preferably Italian-style): Adds texture and helps the meatballs hold their shape perfectly.
- 1/4 cup grated Parmesan cheese: Gives a salty, nutty depth to the meat mixture.
- 1 egg: Acts as a natural binder to keep the meatballs tender.
- 1 tsp dried oregano: Infuses the meatballs with an earthy, aromatic warmth.
- 1 tsp garlic powder: Delivers a subtle punch of savory garlic flavor.
- 1/2 tsp salt: Enhances all the other flavors beautifully.
- 1/2 tsp pepper: Adds just the right amount of mild heat.
- 2 tbsp chopped fresh parsley (optional): Brings a fresh, green note that brightens the meatballs.
- 1/4 cup milk: Keeps the meatballs moist and tender throughout baking.
- 12 mini sub rolls or slider buns: The perfect vessel for your meatball masterpiece.
- 2 cups marinara sauce: Rich and tangy tomato sauce that coats the meatballs wonderfully.
- 1 1/2 cups shredded mozzarella cheese: Melted to bubbly, cheesy perfection for that irresistible finish.
- Fresh basil (optional, for garnish): Adds a pop of color and a fragrant touch to serve.
How to Make Mini Meatball Subs with Marinara and Mozzarella Recipe
Step 1: Preheat Your Oven
Start by setting your oven to 400°F (200°C). Line a baking sheet with parchment paper or a silicone baking mat to ensure the meatballs won’t stick and bake evenly. This warm oven environment will cook your meatballs to juicy, golden perfection.
Step 2: Make the Meatballs
In a large mixing bowl, combine your ground meat with the Italian-style breadcrumbs, grated Parmesan, egg, oregano, garlic powder, salt, pepper, fresh parsley if using, and milk. Mix everything just until combined — avoid overworking the meat to keep your meatballs tender and juicy. Shape the mixture into small 1 to 1 1/2 inch meatballs and arrange them on your prepared baking sheet.
Step 3: Bake the Meatballs
Pop the baking sheet into your preheated oven and let the meatballs bake for 12 to 15 minutes. You want them lightly browned on the outside and cooked through internally. This step ensures a savory crust with a moist center that will soak up that delicious marinara later.
Step 4: Prepare the Sauce
While the meatballs are baking, warm your marinara sauce over low heat in a small saucepan. Once the meatballs are out of the oven, gently transfer them into the simmering marinara and toss to coat them evenly. This locks in moisture and infuses the meatballs with that classic tomato flavor.
Step 5: Assemble the Subs
Slice your mini sub rolls or slider buns in half without cutting all the way through, so they hold the filling snugly. For an extra touch, lightly toast the buns in the oven for 2 to 3 minutes — this adds a fantastic crunch and keeps them from getting soggy.
Step 6: Build the Subs
Nestle 2 to 3 sauced meatballs inside each bun. Spoon over some extra marinara to keep every bite saucy and tender, then pile on the shredded mozzarella cheese generously. Don’t be shy — this cheese brings everything together with its creamy melt.
Step 7: Melt the Cheese
Return your assembled mini subs to the oven for about 5 minutes, or until the mozzarella is melted and bubbling delightfully. This finishing bake melds the flavors and textures, turning your sandwich into the ultimate comfort food treat.
Step 8: Serve Your Mini Meatball Subs with Marinara and Mozzarella Recipe
Pull those golden, cheesy subs from the oven, garnish with fresh basil leaves if you have them, and serve warm. Each bite delivers a satisfying blend of meaty, tomatoey, and cheesy goodness that’s impossible to resist.

Garnishes
Adding fresh basil or chopped parsley on top brightens the dish and adds a lovely herbal aroma. For an extra indulgent touch, sprinkle some grated Parmesan cheese or drizzle a little olive oil just before serving.
Side Dishes
These mini subs pair beautifully with crisp side salads, roasted vegetables, or even classic garlic fries. A bowl of crunchy coleslaw or a fresh Caesar salad also works wonders to balance out the richness of the sandwiches.
Creative Ways to Present
Bring a fun twist by serving these mini subs as part of a sandwich platter with an assortment of dips like pesto, spicy mayo, or extra marinara. You can also layer them on a baking tray for a casual party spread where everyone can grab their own warm, gooey treat!
Make Ahead and Storage
Storing Leftovers
Leftover meatball subs are best stored in an airtight container in the refrigerator and eaten within 3 days. Keep the subs intact if possible, or store components separately to maintain freshness.
Freezing
If you want to freeze these Mini Meatball Subs with Marinara and Mozzarella Recipe, wrap each sub tightly in plastic wrap and then foil to prevent freezer burn. They will keep well for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
To reheat, bake the subs in a preheated 350°F (175°C) oven for about 10-15 minutes or until warmed through and the cheese is melty again. You can also use a microwave for convenience but baking preserves the toasted texture of the bread.
FAQs
Can I use turkey or chicken instead of beef for the meatballs?
Absolutely! Ground turkey or chicken can be a leaner alternative. Just be sure to not overcook as they tend to dry out faster, and consider adding a bit more milk to keep the meatballs moist.
Is it possible to make these meatballs gluten-free?
Yes! Swap out the regular breadcrumbs for gluten-free breadcrumbs, and double-check that your marinara sauce is gluten-free. The subs themselves might need gluten-free buns to keep the whole sandwich safe for those with gluten intolerance.
Can I prepare the meatballs in advance and freeze them before assembling?
Definitely. You can shape and bake the meatballs ahead of time, then freeze them on a tray before transferring to a sealed container or bag. This way, you can quickly thaw and assemble the subs when ready.
What’s the best way to keep the rolls from getting soggy?
To prevent soggy rolls, lightly toast or grill the buns before assembling. Also, avoid soaking the bread in too much sauce by spooning marinara carefully over the meatballs rather than directly onto the bread.
Can I add other toppings to these mini subs?
Of course! Sautéed onions, roasted peppers, or pepperoni slices make fantastic toppings that add extra flavor and texture. Feel free to get creative and customize your subs to your liking.
