I’ve made these a bunch of times for game days and backyard hangs, and they never miss. It’s basically a big meatball sub baked into one giant loaf – all the flavor, none of the fuss. You can slice it up and feed a crowd, or just grab a piece and dive in. Every bite of the Meatball Party Sandwich has that perfect combo of garlic butter, melted cheese, and tender meatballs soaked in marinara.

Why You’ll Love It
This Meatball Party Sandwich recipes is comfort food at its best. The meatballs are homemade and full of flavor from the mix of beef, pork, garlic, and herbs. They stay juicy thanks to the breadcrumbs and milk, and when they bake in the sauce, they get even better. Add that to buttery French bread and gooey melted cheese, and it’s hard not to fall in love with this one.

It’s also super easy to prep ahead. Make the meatballs earlier in the day, stash them in the fridge, and throw it all together right before people show up. You can even bake it right on the grill if you’re outside – it holds up great. It’s messy in the best way and guaranteed to get a few “wow” reactions. The meatball party sandwich just doesn't miss!
This Meatball Party Sandwich works for just about anything – parties, football Sundays, or even a random weeknight when you’re craving something big and hearty. It’s the kind of meal that makes you want to grab a cold drink and a few napkins.

Ingredients and Tools
You don’t need much to make the Meatball Party Sandwich happen – just a good loaf of French bread, some mozzarella, provolone, and a few pantry staples. The bread acts like a crispy boat that holds all the sauce and cheese without getting soggy. Melted butter mixed with garlic and parsley gives it that perfect flavor base.
For the meatballs, you’ll need ground beef and pork, breadcrumbs, Parmesan, eggs, milk, and seasonings. It’s a simple mix that delivers big flavor. I like to brown mine in a skillet first to get a little crust on them before finishing in marinara.

A cast iron pan works best for searing, but any skillet will do. You’ll also want a baking sheet, a sharp knife, and a big spoon for loading everything into the bread.
How to Make a Meatball Party Sandwich
Start by heating your oven to 350°F. Mix up your meatballs by combining the beef, pork, breadcrumbs, Parmesan, milk, eggs, garlic, parsley, and seasonings. Use your hands and mix just until it comes together – if you go too far, they’ll turn tough. Roll into balls about 2½ inches wide.
Heat olive oil in a skillet and brown the meatballs on all sides. Once they’ve got a little color, pour in your marinara sauce and bake until they hit 165°F inside. While they finish cooking, grab your French bread and hollow it out a bit to make space for the filling. Brush the inside with melted butter, garlic, and parsley, then toast it in the oven for 5 to 7 minutes.

Once the bread’s ready, it’s time to build. Lay down the provolone slices first so they melt into the bread. Add your hot meatballs and a little extra sauce, then top with mozzarella. Sprinkle some Italian seasoning over the top and bake again until the cheese melts and bubbles.
Let it cool just a minute before slicing. Each piece should have a bit of everything – the crunch, the cheese, the sauce, and those juicy meatballs. It’s messy, but that’s part of the fun.
Serving Tips and Variations
These Meatball Party Sandwiches are a hit as-is, but you can switch things up if you want. For a little heat, add sliced jalapeños or a drizzle of hot honey before baking. If you like it extra cheesy, mix in a bit of sharp provolone or fontina with the mozzarella.
You can also make a smoky version by swapping the marinara for BBQ sauce. It sounds wild, but trust me – it works. Add a few pickled peppers on top, and you’ve got a crowd-pleaser that feels totally different but just as good.

If you’re serving a big group, slice the sandwich into smaller portions and pile them on a platter with some warm marinara on the side for dipping. It’s the kind of food people gather around.
Pro Tips and Recipe Notes
- Use fresh mozzarella if you can – it melts smoother and stretches beautifully.
- Toast the bread before loading it up so it stays crisp under the sauce.
- A mix of beef and pork makes a big difference in flavor and tenderness.
- Make the meatballs ahead to save time, or freeze a batch for later.
- If you’ve got leftovers, wrap them in foil and reheat in the oven until hot again.
