Create the best Italian Meatball Sub at home with this easy, tested and perfected recipe! In this epic sub sandwich, a warm, crusty roll is filled with juicy, tender meatballs, flavorful marinara sauce, and plenty of melty cheese. It truly is the best sandwich ever, and super easy to make with leftover Italian meatballs!
Add the cooked meatballs and marinara sauce to a large saucepan on the stove and simmer for 10 minutes.
Slice the demi baguettes in half lengthwise through the middle. Top the bottom half of each baguette with two slices of mozzarella cheese, cut in half lengthwise, and overlapping on the bread. Place the top half of the baguette on top of the cheese. Place in the oven for 5 minutes.
Remove the baguettes from the oven, remove the top half of the bread, then add 6 meatballs tossed in marinara sauce to each demi baguette (or add all of them to a whole baguette).
Top each of the sandwiches with another two slices of mozzarella cheese, cut in half lengthwise, and overlapping on top of the meatballs. Place the sandwich back in the oven for another 3-5 minutes, or until the cheese has melted over the meatballs.
Remove the meatball subs from the oven, partially remove the top piece of bread, sprinkle the meatballs with parmesan cheese, and add basil leaves if you’d like. Slice both in half, so you end up with four sandwiches for serving.
Notes
Refer to the blog post above for my easy homemade Italian meatball recipe. You can also use frozen meatballs, just make sure they're fully cooked before starting this recipe.
This meatball sub sandwich is best served hot and fresh out of the oven. You can store leftover saucy meatballs in the fridge for up to 5 days and make a fresh sandwich whenever you’re ready for another one!
