    This frozen meatball sub recipe is a favorite dinner on busy days during the school year -- especially during football season! It's a simple recipe with minimal prep time that is easy, budget friendly and delicious!

    Instead of spending money on takeout, you can make these meatball subs at home for a lot less. Another reason why it's a favorite recipe! All you really do is add the ingredients to your slow cooker, and it does the work for you.

    You can also cook frozen meatballs in the Instant Pot. But on busy nights when we're on different dinner schedules, this crockpot meatball sub recipe works better.

    Ingredients

    You only need a few simple ingredients to make easy crockpot meatball subs. If you don't have them at home, you can find them in your grocery store.

    • Frozen meatballs -- I used pork and beef Italian meatballs here, but all beef meatballs, turkey meatballs or any kind works
    • Marinara sauce -- We love Rao's, but use your favorite jar of spaghetti sauce
    • Seasonings -- garlic powder, Italian seasoning, parsley for extra flavor
    • Hoagie rolls -- or any thick crusty rolls
    • Cheese -- we love provolone cheese and mozzarella cheese. Parmesan cheese works as a topper

    Note -- You can use homemade meatballs if they're already cooked for homemade meatball subs. I have an awesome homemade meatball recipe, but I love frozen meatballs for convenience.

    How to Make Slow Cooker Meatballs with Jar Sauce

    First, spray the bottom of the crock pot with non stick cooking spray. You can use olive oil or crock pot liners if you like.

    Next, add the frozen meatballs in a single layer on the bottom of the slow cooker.

    Then, pour the jar of pasta sauce over the meatballs. Sprinkle the garlic powder, Italian seasoning and dried parsley on top of the sauce.

    Spread the tomato sauce evenly over the meatballs. Then, place the lid on the crock pot.

    Cook Time

    Cook the frozen meatballs for 2 to 3 hours on high or 4 to 6 hours on low or until they are heated through.

    Stir meatballs and sauce once or twice during the cooking process.

    Meatball Sandwich Recipe

    To make meatball sandwiches, slice open the hoagie rolls, and place a slice or slices of provolone cheese on the bottom of the roll so that it covers the top and bottom.

    Spoon a few meatballs and sauce over the cheese, and close the roll so that the top of the cheese melts over the meatballs. Serve with extra sauce for dipping!

    You can top with mozzarella cheese if you like for extra cheesy meatball subs.

    Toast the soft hoagie bun first if you like crispy bread for subs or if you're using hot dog buns. If you're using thick crusty sub rolls or crusty bread, it's not necessary.

    Place the subs on a baking sheet and bake for 2 or 3 minutes in a hot oven for gooey melted cheese. Yum!

    How to Store and Reheat

    Store leftover meatballs in an airtight container in the refrigerator for up to 4 days. Reheat meatballs in the microwave until steaming.

    You can freeze meatballs and sauce in freezer safe container for up to 3 months for best taste.
