Everyone in town orders sandwiches from them for any kind of event, because they’re cheap and they are such a crowd pleaser.

We get delivery from them about once a month and I usually just split a gondola with my husband, but a few months I decided to branch out. I got a meatball sub.

Y’all, I honestly think it was the first time I’d ever ordered a meatball sandwich! I. am. obsessed. Like, super obsessed.

How to make crockpot meatballs:

I like this recipe because it uses the slow cooker. Keep life simple and enjoy a meatball sandwich. Right? 😉

So, you’re going to toss all of your good stuff (ground beef, ground pork, bread crumbs, Parmesan, and some seasonings) into a large bowl and get to mixing.

I normally use my hands to mix meatballs together. This way you don’t overmix and end up with tough meatballs.

Roll the meat mixture into meatballs and pop them on a cookie sheet.

We’re going to stick these in a hot oven for 10 minutes, just to be sure they get a little brown on the outside and they hold together well in the crockpot. This will also help get a little fat off of them before we add them to the sauce. They’ll finish cooking in the crockpot.

You could add these meatballs to plenty of different sauces in your slow cooker, but we’re going for meatball subs and that means tomato sauce today!

Crockpot Italian Meatballs:

These are Italian meatballs, my friends! That means we need a nice tomato sauce to cook these little guys in.

Grab your favorite slow cooker (here’s mine! <– Affiliate link) and start adding the ingredients for the sauce.

You’ll want to start with a jar of marinara. I normally use Rao’s, but your favorite brand will work just fine.

You’ll also add in a can of crushed tomatoes, plenty of minced garlic, some onion powder, and a little dash of red pepper flakes. You can add more red pepper, if you want a spicier meatball sub.

Stir your tomato sauce together and add those meatballs in.

Cover and cook on low for 4 hours.

I top my slow cooker meatballs with plenty of fresh parsley.

Meatball Sub:

Grab some hoagie rolls, my friend. It’s time to turn those slow cooker meatballs into a delicious meatball sandwich.

Open up your bread and spread the insides with butter. Sprinkle on a little garlic salt.

Pop the bread under the broiler for a minute or two until it’s as toasty as you’d like.

To assemble the sandwich, add a few meatballs to the bread. I can normally fit 3 meatballs per roll, but it will depend on the length of the bread you buy.

Top the meatballs with a little extra sauce and then some fresh mozzarella slices. Sprinkle on a little more parsley and return all this to the broiler for a minute to let the cheese get a bit melty.

Homemade meatballs made in the crockpot are perfect for stuffing inside a toasty hoagie roll. These meatball subs are a favorite around here.

Ingredients

For the meatballs:
  • 1 pound ground beef
  • ½ pound ground pork
  • 1 cup Italian style bread crumbs
  • 1/4 cup powdered Parmesan
  • ¼ cup chopped parsley
  • 2 cloves garlic minced
  • 1 onion minced
  • 1 egg
For the sauce:
  • 28 ounce jar marinara
  • 15 ounces crushed tomatoes
  • 4 cloves garlic minced
  • 1 teaspoon onion powder
  • ¼ teaspoon red pepper flakes
  • 1 teaspoon salt
  • ½ teaspoon sugar
For the subs:
  • 4 hoagie rolls
  • 4 tablespoons butter softened
  • 2 teaspoons garlic salt
  • 8 slices fresh mozzarella cheese
  • 1 tablespoon parsely minced

Instructions

To make the meatballs:
  1. Preheat oven to 400 degrees. Spray a rimmed baking sheet with non-stick spray.
  2. Add the ground beef, pork, bread crumbs, Parmesan, parsley, garlic, onion, and egg to a large mixing bowl and combine well with your hands. Do not overmix.
  3. Separate the mixture into 12 equal sized chunks and roll into meatballs.
  4. Place meatballs on prepared baking sheet and bake for 10 minutes.
To make the sauce:
  1. Add all of the sauce ingredients to a 6 quart slow cooker and stir well to combine.
  2. Remove the meatballs from the oven and place in the slow cooker with the sauce.
  3. Cover and cook on low for 4 hours.
To make the subs:
  1. Open the hoagie rolls and butter the insides of each roll.
  2. Sprinkle evenly with the garlic salt, about ½ teaspoon per roll or to taste.
  3. Place opened hoagie rolls on a large baking sheet under the broiler and broil until as toasted as you’d like. Keep a close eye on the bread as it will go from toasted to burnt very quickly.
  4. Remove the bread from the oven and add meatballs to the bread. Top with a spoonful of sauce.
  5. Top each sandwich with 2 slices of fresh mozzarella and a sprinkling of parsley.
  6. Return to the broiler for 1 minute to let the cheese soften.
  7. Serve immediately.

Recipe Notes

Add more red pepper flakes for a spicier tomato sauce. 

Use Hawaiian rolls to make meatball sliders instead of subs.
