1bagfrozen meatballs1-ounce meatball size, 26 ounce bag
6hoagie subsgluten-free or low-carb bread works fine
6slicesmozzarella cheese
¾cupgrated parmesan cheese
1cupmarinara sauce+ more for dipping or if you like it extra saucy
1-2handfulsbasil leaves
Instructions
Preheat the air fryer to 375 degrees for 3 minutes.
Pour in the meatballs, keeping them in a single layer and allowing as much room as possible for air to circulate (cook in batches if necessary). Cook for 12-15 minutes, shaking the basket every 3-5 minutes for even cooking.
Open up hoagie buns. Sprinkle parmesan on the inside of the top and bottom.
Once meatballs are finished cooking, remove and set aside on a plate. Carefully place the parmesan-covered buns into the air fryer and allow it to cook at 375 degrees F for 1-3 minutes or until golden brown. This creates a nice barrier, preventing the sauce from making the buns soggy later.
Place toasted buns on a plate, brushing the bottom pieces with marinara sauce. Cover with basil leaves, then top with meatballs. Spoon additional marinara sauce over the meatballs, top with cheese.
Return assembled sandwiches to the air fryer, toasting on 375 degrees for another 1-3 minutes or until cheese has melted. Serve immediately.
Notes
I used 1-ounce frozen meatballs. If you use smaller, 1/2-ounce meatballs, only cook for 10-12 minutes in Step #2.
