Ingredients You’ll Need
These ingredients are simple but play crucial roles in shaping the rich taste, texture, and even a pop of color in your Mini Meatball Subs Recipe. Each element is carefully chosen to balance hearty, savory, and cheesy goodness.
- 1 lb ground beef: The juicy base for your meatballs, offering rich flavor and protein.
- ¼ cup breadcrumbs: Adds structure and tenderness to the meatballs.
- 1 egg: Acts as a binder to keep the meatballs perfectly firm yet tender.
- 2 tablespoons grated Parmesan cheese: Infuses a sharp, nutty flavor that deepens the meatballs.
- 2 cloves garlic (minced): Brings bold aroma and a savory punch to every bite.
- 1 teaspoon Italian seasoning: A fragrant blend that elevates the entire dish with classic herbal notes.
- ½ teaspoon salt: Enhances the flavors without overpowering them.
- ¼ teaspoon black pepper: Adds just the right amount of mild heat.
- 1 tablespoon olive oil: Used to brown the meatballs perfectly and add richness.
- 2 cups marinara sauce: The heart of the dish, delivering tangy tomato comfort.
- 12 slider buns or small sub rolls: Soft and fluffy, ideal for holding all that meaty goodness.
- 1½ cups shredded mozzarella cheese: Melts beautifully to create that irresistible cheesy topping.
- Chopped fresh parsley (optional, for garnish): Adds a fresh, bright pop of green and subtle freshness.
How to Make Mini Meatball Subs Recipe
Step 1: Prepare the Meatball Mixture
Start by combining ground beef, breadcrumbs, egg, Parmesan cheese, minced garlic, Italian seasoning, salt, and black pepper in a large bowl. Mix everything gently until just combined to avoid tough meatballs. Then, roll this mixture into 1-inch meatballs — these little guys will pack the perfect punch of flavor and fit snugly in your slider buns.
Step 2: Brown the Meatballs
Heat olive oil in a large skillet over medium heat. Once hot, add your meatballs and cook them until golden brown on all sides, which usually takes about 6 to 8 minutes. Browning not only locks in flavor but also gives the meatballs a delightful texture that contrasts with the soft bun later.
Step 3: Simmer in Marinara Sauce
After browning, pour in the marinara sauce and reduce the heat to low. Allow the meatballs to gently simmer for 10 to 12 minutes. This step ensures they are fully cooked through and soak up the savory tomato flavors, making every bite juicy and comforting.
Step 4: Assemble the Subs
Arrange your slider buns on a baking sheet. Place 2 to 3 meatballs along with some marinara sauce into each bun. Generously sprinkle shredded mozzarella cheese over the meatballs to create that mouthwatering, melty top layer.
Step 5: Bake Until Cheese Melts
Pop the baking sheet into a preheated oven at 375 degrees Fahrenheit and bake for 5 to 7 minutes, just until the mozzarella is melted, bubbly, and perfectly golden. This final touch seals all the flavors in and gives a gorgeous texture that you can’t wait to sink your teeth into.
How to Serve Mini Meatball Subs Recipe

Garnishes
A sprinkle of chopped fresh parsley does wonders here, adding a burst of color and a subtle freshness that brightens the richness of the meatballs and cheese. You can also experiment with a dash of crushed red pepper flakes if you enjoy a little heat.
Side Dishes
Keep your mini meatball subs company with sides like crispy garlic fries, a fresh Caesar salad, or even classic coleslaw. These sides balance the hearty subs and offer texture contrasts, making your meal feel complete and satisfying.
Creative Ways to Present
Serve these mini meatball subs on a large platter with toothpicks to make them perfect party finger food. You could also line them up on a wooden board with small bowls of extra marinara sauce for dipping — it’s both practical and visually inviting!
Make Ahead and Storage
Storing Leftovers
Place any leftover mini meatball subs in an airtight container and refrigerate for up to 3 days. Keeping the buns separate or wrapping them tightly prevents sogginess, maintaining that delightful texture when you reheat.
Freezing
You can freeze assembled subs before baking by wrapping them tightly in foil or plastic wrap and storing them in a freezer-safe bag. They’ll keep well for up to 2 months, perfect for quick meals whenever the craving hits.
Reheating
For the best results, reheat your subs in an oven set to 350 degrees Fahrenheit for about 10 to 15 minutes or until warmed through and the cheese is melted again. Microwaving works in a pinch but may leave the buns a little soggy.
FAQs
Can I use different meats for the meatballs?
Absolutely! Ground turkey or chicken are excellent lighter alternatives that still taste fantastic with marinara and cheese. Just adjust cooking times accordingly to ensure they’re fully cooked.
Can this Mini Meatball Subs Recipe be made vegetarian?
Yes, you can substitute the meatballs with vegetarian or plant-based meatballs available at most grocery stores to keep the same great flavor and texture.
How can I make the subs spicier?
Add crushed red pepper flakes to the meatball mixture or sprinkle some on top before serving. You could also mix a bit of hot sauce into the marinara for an extra kick.
What’s the best bread to use if I can’t find slider buns?
Small hoagie rolls or dinner rolls make great substitutes as long as they’re soft and easy to bite into. You could lightly toast them to enhance texture.
Can I prepare the meatballs ahead of time?
Yes! You can make the meatballs a day in advance and keep them refrigerated or even freeze them before simmering in the sauce. This saves time on busy days.
