How to Make Easy Meatball Sub Recipe

Step 1: Heat the Meatballs

Start by warming your frozen meatballs in the marinara sauce on the stovetop over medium heat. This step not only heats through the meat but allows the meatballs to absorb that vibrant tomato flavor, making every bite tender and juicy. Stir occasionally to ensure even heating and to prevent sticking.

Step 2: Prepare the Sub Rolls

While the meatballs are warming, slice your sub rolls open but leave a hinge on the back for easy filling. If you want to step it up a notch, spread a little garlic butter inside the rolls and toast them lightly under the broiler beforehand for an irresistible crunch and aroma.

Step 3: Assemble the Subs

Once your meatballs are hot and bubbling with marinara, spoon them generously into each prepared sub roll. Don’t hold back—make sure each roll gets plenty of that sauce and tender meat for that classic moist, hearty texture.

Step 4: Top with Cheese and Broil

Sprinkle shredded mozzarella evenly over the meatballs in each sandwich. Place the subs under the broiler for 2 to 3 minutes, watching closely until the cheese melts beautifully and develops those irresistibly golden, bubbly spots. This quick broil adds a gorgeous finish that’s as eye-catching as it is delicious.

Make Ahead and Storage

Storing Leftovers

If you find yourself with leftovers, simply place the meatballs and sauce in an airtight container and store them in the fridge for up to three days. Keep sub rolls separate to avoid sogginess and assemble fresh before reheating.

Freezing

This Easy Meatball Sub Recipe also freezes well. Freeze meatballs and sauce in a freezer-safe container for up to two months. When ready, thaw overnight in the fridge before reheating and assembling. Bread freezes best if wrapped tightly to maintain freshness.

Reheating

Reheat meatballs and sauce gently on the stovetop or microwave until warmed through. To revive that freshly broiled texture, place assembled subs under the broiler for a minute or two until cheese bubbles again. This quick step restores the irresistible finish you love.

FAQs

Can I use homemade meatballs instead of frozen?

Absolutely! Homemade meatballs add a personal touch and you can season them exactly how you like. Just make sure they’re cooked through before warming with the marinara and assembling your subs.

What type of cheese works best for this recipe?

Mozzarella is a classic choice for that melty, mild flavor, but provolone or a mozzarella-provolone blend also works wonderfully. Choose cheeses that melt easily and complement the sauce without overpowering it.

Can I add vegetables to the meatball subs?

Definitely! Sautéed onions, bell peppers, or even mushrooms add tasty layers of flavor and texture. You can mix them into the marinara or place them directly in the sub rolls before adding the meatballs.

How can I make this recipe spicier?

Add a pinch of red pepper flakes in the marinara sauce or top the finished subs with sliced jalapeños for a nice kick. Spicy sausage meatballs are another great option to amp up the heat.

What’s the best way to prevent the bread from getting soggy?

To keep the rolls from soaking up too much sauce and becoming soggy, lightly toast or grill them before assembling. Also, serve the subs soon after assembling for the best texture experience.
