Meatball Marinara Sub Recipe
The Meatball Marinara Sub is a delicious sandwich that you can make at home in just minutes.
Guess what? No one will ever know that you used frozen meatballs.
If you have any sauce left in the baking pan, spoon that into bowls and use that as extra dipping sauce. Just Scrumptious!




Can you cook frozen meatballs in sauce?
Yes, I just add the frozen meatballs to a baking dish and pour the sauce over the top. When the meatballs cook, some of their juice leaks out and adds to the complex flavors of the sauce. This is such an easy way to cook meatballs. Perfect for those times when you did not plan ahead for the meal.
Make the Marinara Sauce and Meatballs in a Slow Cooker
Just add the frozen meatballs and sauce to a slow cooker and cook on low for 3-4 hours or high for 1 ½ hours.
Just before serving you can add the shredded cheese to the slow cooker to melt or top the sub sandwiches with the cheese to melt just before you eat.




What Kind of Cheese is Good for Meatball Subs?
To help make these subs taste more like a hearty comfort food type of meal, I like to use a good melting cheese like mozzarella, provolone, gouda, or parmesan.




What Kind of Sauce Goes on a Meatball Sub?
I like to use a jarred spaghetti sauce, one that is loaded with vegetables. However, whatever your favorite jar of sauce is can be used. I often have one in my pantry for quick meals like this. If you prefer to make your own marinara sauce you certainly can.
How do you reheat a meatball sub in the oven?
Just repeat the oven to 350 degrees F. Place the sub on a baking sheet lined with foil and bake for 15 minutes. The bun will be toasty, and the meatballs and sauce will be hot.




What goes on a meatball marinara sub?
I prefer to keep things simple using just 5 ingredients. Frozen meatballs, marinara sauce, and shredded mozzarella.

Kitchen Essentials
Ingredients
- 26 ounces frozen meatballs I used an Italian style made with beef, pork, and chicken
- 45 ounces spaghetti sauce I used Ragu Chunky Sauce Garden Combination

- 10 Hoagie Rolls
- 10 Tablespoons Butter
Instructions
- Place the meatballs in a 9 X 13 baking dish and pour the marinara sauce over the top.
- Add the shredded mozzarella cheese and bake for 35 minutes until the cheese is melted and the sauce is bubbling in an oven preheated to 375 degrees F.
- While the meatballs are baking, cut the rolls almost in half lengthwise. Spread lots of butter to each roll spreading it on both halves. Place them on a baking sheet with the butter side up and bake for 15 minutes until they are lightly toasted.
- To make the sandwiches, spoon meatballs in the center of the bun adding more sauce as needed.
