  • Precooked meatballs – You can purchase frozen meatballs or use your favorite homemade meatball recipe for this. Either will work well. Just be sure to warm them slightly before adding them to the subs.
  • Hoagie Rolls – Fresh baked rolls are always my favorite! Gluten-free or whole wheat rolls are both good “healthier” options.
  • Marinara Sauce – Jarred sauce is easiest, but homemade sauce is always better.
  • Mozzarella Cheese – Melts to add the perfect amount of gooey cheesiness.
  • Parmesan Cheese – Adds just a hint of saltiness and a nutty flavor.

🔪 How to Make the Best Meatball Subs


Preheat

Preheat the air fryer to 350 degrees for 5 minutes. While it preheats, assemble the sandwiches.

Assemble the Subs

  1. If needed, slice open each roll. Place 4 warmed, precooked meatballs inside each.

👉 PRO TIP: If you’re using frozen meatballs, cook them in the air fryer first for 9-11 minutes, shaking the basket halfway through the cooking time. If using leftover meatballs, warm them for 2-3 minutes.

  1. Top the meatballs with 1/4 cup of marinara sauce and 1/4 cup of the mozzarella and parmesan mix.
  2. Place the assembled subs into the air fryer basket in a single layer. Air fry at 350 degrees for 3-5 minutes or until the cheese is melty and the bread begins to toast. Depending on the size of your fryer, you may be able to cook two subs at the same time. If you have a smaller air fryer, cook them in batches.
  3. Serve immediately and enjoy!

❗ Recipe Tips


  • You can use pre-shredded cheese, or grate fresh cheese from a block.
  • Want to make a slightly healthier sub? Try using turkey meatballs, whole wheat bread, and no sugar added marinara sauce!
  • Love a good toasty sandwich? Try brushing a bit of olive oil or melted butter onto the outside of the rolls before cooking. This should allow them to crisp up nicely.
  • Include a little fresh parsley on top for a pop of color (remember, we eat with our eyes first!)
  • Serve a small bowl of extra marinara sauce on the side for dipping!

🔀 Recipe Variations


Put your own touch on this recipe by swapping out a few of the key ingredients for some fun substitutions. Below are a few of my favorite variations.

  • Loaded Veggie Variation – Pack the sandwiches full of sliced bell peppers, spinach, onion, olives, or mushrooms before air frying. If you want less of a raw veggie crunch, lightly sauté the veggies first in a little olive oil with a sprinkle of Italian seasoning.
  • Pesto Tomato Variation – Swap out the marinara sauce for pesto and add slices of fresh tomato for a salty, herby, and earthy sub.
  • Garlic and Herb Variation – Brush the inside and outside of the rolls with melted butter and sprinkle with garlic powder, oregano, and dried basil before adding the other ingredients.
  • Quadruple Cheese Variation – In addition to the mozzarella and Parmesan, try adding provolone and gorgonzola to create a super cheesy sandwich!

🍚 Storage


Leftovers will keep in the fridge for up to 4 days. I recommend wrapping each leftover sandwich in aluminum foil to prevent them from getting too soggy.

To reheat, pop them back in the air fryer for 2-5 minutes or until warmed through and once again crispy.

Freezer storage is not recommended.

❓ Questions About Air Fryer Meatball Subs


Should I use store-bought or homemade meatballs?

It just depends on your personal preference and what you have on hand. When I’m in a pinch, I use frozen meatballs. However, I do find homemade meatballs to be a bit tastier.

What can I serve with meatball subs?

I love serving these subs with crispy french fries and extra marinara dipping sauce. For a lighter, healthier option, try a fresh garden salad, some roasted veggies, or a fresh fruit smoothie.

What kind of bread is best for meatball subs?

Any kind of long, skinny roll will work well. Hoagies, French or Italian bread, or even hot dog buns will work in a pinch!

How do I keep my subs from getting soggy?

If you find that your sandwiches come out a bit soggy, you can try pre-toasting the bread and using less marinara sauce. Or omit the sauce and serve it on the side for dipping when serving.
