How to Make Mini Meatball Subs Recipe

Step 1: Mix the Meatball Ingredients

Start by preheating your oven to 375°F (190°C). In a large mixing bowl, gently combine the ground beef, breadcrumbs, egg, Parmesan, minced garlic, Italian seasoning, salt, and black pepper. The key is to mix just until everything is incorporated without overworking the meat, which keeps the meatballs tender and juicy.

Step 2: Form and Bake the Meatballs

Shape the mixture into 18 to 20 small meatballs, about the size of a tablespoon each. Place them evenly spaced on a baking sheet lined with parchment paper. Bake for 15 to 18 minutes, or until cooked through and lightly browned. This baking method ensures a hands-off way to get perfectly cooked meatballs without frying mess.

Step 3: Warm and Simmer in Marinara

While the meatballs are baking, pour the marinara sauce into a saucepan over medium heat until warmed through. When the meatballs finish baking, transfer them gently into the simmering sauce. Let them soak and simmer for about 5 minutes, allowing those flavors to mingle and the meatballs to soak up all that delicious tomato goodness.

Step 4: Assemble the Subs

Slice your mini sub rolls horizontally but leave a hinge so they stay intact. To each sub, add about three meatballs with some sauce, spooning generously to keep things saucy and flavorful. Sprinkle shredded mozzarella cheese over the top before placing the filled subs on a baking sheet.

Step 5: Melt the Cheese

Pop the assembled subs into the oven for an additional 5 to 7 minutes, or until the mozzarella is melted, bubbly, and golden in spots. This final bake gives the subs an irresistible cheesy finish that ties the whole sandwich together.

How to Serve Mini Meatball Subs Recipe

Garnishes

Sprinkle freshly chopped parsley over the melted cheese right after baking. This simple garnish not only adds a stunning pop of green color but also refreshes the palate, balancing the richness of the meat and cheese beautifully.

Side Dishes

Mini Meatball Subs pair wonderfully with crispy potato chips or a crisp green salad to balance the comfort with some fresh crunch. For a heartier meal, garlic roasted vegetables or a warm Caesar salad complement the Italian flair perfectly.

Creative Ways to Present

For a party or casual gathering, array these mini subs on a large platter with toothpicks for easy grabbing. You can also serve them open-faced for a fun twist or add a drizzle of balsamic glaze or a sprinkle of chili flakes for guests who like a bit more kick.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers, wrap the subs tightly in foil or place them in an airtight container. They’ll stay fresh in the refrigerator for up to 3 days, making them a great option for next-day lunches;

Freezing

You can freeze the assembled subs before baking. Wrap each sub individually in plastic wrap and foil and freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge and then bake until heated through and cheese is bubbly.

Reheating

To reheat, place the subs in a preheated 350°F oven for about 10 to 15 minutes, or until warmed through. This will keep the bread from getting soggy and restore that fresh-from-the-oven feeling.

FAQs

Can I use store-bought meatballs for this recipe?

Absolutely! Using store-bought meatballs is a fantastic shortcut that saves time without sacrificing flavor. Just be sure to warm them thoroughly in marinara sauce before assembling your subs.

What can I substitute for the Italian seasoning?

If you don’t have Italian seasoning on hand, a combination of dried oregano, basil, and thyme works perfectly. Feel free to adjust proportions to your taste to keep that classic flavor profile.

Can I make these subs gluten-free?

Yes! Simply substitute the buns with your favorite gluten-free mini rolls and use gluten-free breadcrumbs. The rest of the recipe remains the same and just as delicious.

Is it possible to bake the subs all at once instead of two steps?

While you can bake assembled subs from scratch, baking meatballs separately first helps ensure even cooking and juiciness. The second bake melts the cheese without overcooking the meatballs, but if you’re in a hurry, assembling and baking at once works in a pinch.

How do I keep the meatballs from falling apart?

Precise measurements of breadcrumbs and the egg in the mixture are key, as is gentle mixing. Avoid overhandling the meatball mixture, and baking rather than frying helps them hold their shape while staying tender inside.
