Cheesy Meatball Subs are the perfect combo of juicy meatballs, gooey melted cheese, and warm, soft bread all rolled into one delicious sandwich. The meatballs are hearty and flavorful, and the cheese adds that extra creamy touch that makes every bite so satisfying.
I love making these on a busy night when I want something comforting but easy to put together. It’s one of those meals that feels like a treat but doesn’t take too long to cook. Plus, you can customize the cheese or add peppers and onions if you want a little twist.
The best way to enjoy these subs? Right out of the oven when the cheese is all melty and the bread is slightly toasted. I like to serve them with a side of crispy fries or a simple salad, and it always makes for a happy, filling meal that everyone asks for again and again.

Key Ingredients & Substitutions
Ground Beef & Pork: A mix of beef and pork adds juiciness and flavor. If you want leaner meat, try all beef or turkey. For vegetarian options, use plant-based meatballs.
Breadcrumbs: They help keep meatballs tender. You can swap with oats or gluten-free crumbs if needed.
Parmesan Cheese: Adds a salty depth to meatballs. If you don’t have Parmesan, Pecorino Romano or Asiago work well.
Marinara Sauce: Using good quality marinara makes a big difference. Store-bought is fine, but homemade adds extra freshness. You can even spice it up with red pepper flakes.
Cheese: Mozzarella melts perfectly for that gooey texture. Feel free to use provolone or Monterey Jack for a different taste.
Sub Rolls: Choose soft rolls with a sturdy crust to hold everything together without getting soggy. Italian hoagie rolls or French rolls work great.
How Do I Make Tender, Flavorful Meatballs That Hold Together?
Getting meatballs tender but firm can be tricky. Here’s how I do it:
- Use a gentle hand when mixing ingredients—overmixing makes meatballs tough.
- Breadcrumbs and egg act as binders to keep the meatballs from falling apart.
- Make sure your meatballs are evenly sized for cooking consistency.
- Baking is an easy, less messy way to cook meatballs evenly without frying.
- Simmer the baked meatballs in sauce for a few minutes so they soak up flavor and stay moist.
Equipment You’ll Need
- Baking sheet – perfect for cooking meatballs evenly without added fat.
- Parchment paper – keeps meatballs from sticking and makes cleanup easy.
- Large mixing bowl – to mix meatball ingredients gently without overworking.
- Skillet or saucepan – to warm the marinara sauce and simmer meatballs together.
- Broiler-safe baking sheet – for melting cheese on subs without burning the bread.
- Sharp knife – to slice the sub rolls cleanly and evenly.
Flavor Variations & Add-Ins
- Swap beef for ground turkey or chicken for a lighter sandwich option.
- Add chopped sautéed onions and bell peppers to the meatballs for extra flavor.
- Use provolone or pepper jack cheese instead of mozzarella to change the taste profile.
- Toss meatballs in spicy arrabbiata sauce if you like a bit of heat.

How Much Time Will You Need?
This recipe takes about 10 minutes to prep, 20 minutes to bake the meatballs, plus a few more minutes simmering and assembling the subs. Overall, you’ll be ready to eat in about 35-40 minutes total.
Step-by-Step Instructions:
1. Preheat your oven
Set your oven to 375°F (190°C) so it’s ready for baking the meatballs.
2. Make the meatballs
In a big bowl, mix together the ground beef, breadcrumbs, Parmesan, parsley, egg, minced garlic, oregano, salt, and pepper. Stir gently to combine but don’t overmix—it keeps the meatballs tender.
3. Shape and bake the meatballs
Roll the mixture into 12 equal meatballs and place them on a baking sheet lined with parchment paper. Bake for 15-20 minutes until they’re cooked through and slightly browned.
4. Warm up the sauce and simmer
While the meatballs bake, heat your marinara sauce in a skillet on medium heat. When the meatballs are done, add them to the sauce and let them simmer for 5 minutes. This keeps the meatballs juicy and flavorful.
5. Prepare the rolls and assemble
Slice each sub roll lengthwise, but don’t cut all the way through so they hold together. Spoon 3 meatballs with some sauce into each roll.
6. Add cheese and melt
Top each sub with mozzarella cheese, then place them on a baking sheet under the broiler for 2-3 minutes until the cheese is melted and bubbly—keep an eye on them so they don’t burn.
7. Garnish and serve
Sprinkle some fresh basil on top if you like, and serve your cheesy meatball subs warm. They’re perfect for a filling and delicious meal enjoyed by all!
Can I Use Frozen Meatballs for This Recipe?
Yes, you can use frozen meatballs to save time! Just thaw them in the refrigerator overnight and gently warm them in the marinara sauce before assembling your subs.
What’s the Best Way to Store Leftover Meatball Subs?
Wrap leftover subs tightly in foil or plastic wrap and refrigerate for up to 3 days. Reheat in the oven at 350°F for 10-15 minutes to keep the bread from getting soggy.
Can I Substitute the Sub Rolls?
Absolutely! Any sturdy sandwich roll or even a baguette works well. Just make sure it’s soft on the inside but firm enough to hold the meatballs and sauce without falling apart.
How Do I Make This Recipe Spicier?
Add red pepper flakes to the meatball mixture or use a spicy marinara sauce. You can also top the subs with sliced jalapeños for an extra kick!
