Meatball Sub Recipes

Take the time to make some scratch meatballs. They are so handy to have on hand to make a quick meal on a busy night like spaghetti or an Italian meatball soup. You can easily make chicken, lamb, or beef meatballs with ground meat found at your local grocery store.

This is a favorite recipe, I have now made it countless times over the past decade. The first time I made my own meatballs with sauteed vegetables and parmesan cheese inside, it was a game-changer. Besides adding flavor, it keeps the meatballs tender. Classic meatballs have egg and breadcrumbs and don't get the depth of flavor and richness.

Cheesy Meatball Sub Sandwiches

1 package of sliced mozzarella cheese
3 baguettes sliced open, cut into 3 or 4 sections (or sub rolls)
25-30 homemade meatballs (or frozen bag of meatballs)
16 oz Marinara Sauce (or your favorite pasta sauce)

How To Make Meatballs For Subs

When you have some extra time, make homemade meatballs. It is a great way to have multiple easy dinner ideas ready to go. Sure these take a little effort, but they are so worth it. These are nutritious, healthy, and tasty.

3 lbs lean ground turkey (ground beef or Italian pork sausage)
1 small yellow onion
5 carrots
5 celery stalks cut into 2-3" pieces
½ cup finely chopped basil
½ cup finely chopped parsley
1 small can of tomato paste
1 tablespoon olive oil
1 cup breadcrumbs or ground almonds
½ cup grated parmesan cheese

Make the Meatballs

1. Preheat the oven to 400 degrees.
2. Rough chop veggies in batches and pulse in a food processor or grate on a box grater. 1 small onion, 5 carrots, and 5 celery stalks. Process veggies in batches and place ground vegetables into a large mixing bowl as you go.
3. Next dice ½ cup finely chopped basil, and ½ cup finely chopped parsley into the mixing bowl, and toss together.
4. Heat a large pan or heavy skillet, add 1 tablespoon olive oil and saute the veggies for 3 minutes on medium high heat, keep stirring, then turn off the heat.
5. Place the sautéed veggie mixture in a large mixing bowl, and cool. Next, add 3 lbs ground turkey (or ground beef, Italian pork sausage etc.), 1 cup of breadcrumbs (or ground almonds), and ½ cup of grated parmesan cheese.
6. Stir and completely mix with 2 forks to "fluff" the mixture.
7. Line a large baking sheet with parchment paper. Use a 2" ice cream scoop to portion the meatballs. The ice cream scoop makes the meatballs all the same size, and is faster than hand rolling.
8. Preheat your oven to 400 degrees. Bake 25-30 minutes until golden brown with crispy edges.

Italian Marinara Sauce

2 tablespoons butter
1 tablespoon olive oil
1 large yellow onion diced
1 teaspoon Italian seasoning mix
½ teaspoon black pepper
¼ teaspoon red pepper flakes
½ teaspoon garlic powder
½ teaspoon sugar
1 teaspoon sea salt
28 oz can diced tomatoes
6 oz can tomato paste

1. Heat butter and olive oil in a large heavy pan, add diced onions, saute until soft 5 minutes, then all 6 seasonings, canned tomatoes, and tomato paste.
2. Stir until the marinara sauce thickens about 10-15 minutes. Keep marinara sauce warm.

PRO TIP: This marinara sauce is very easy. I recommend you make a double batch and freeze the extra for spaghetti and your favorite meatballs another night, you will look like a kitchen hero on busy weeknights.

Ingredient Tips & Swaps

Meatballs: Grab a bag of Italian-style meatballs at the store or make some the whole family will love using ground turkey, chicken, pork, or beef.

Bread: Try to use good French baguettes or crusty rolls. Split down the middle and cut into 3-4 portions. Hoagie buns, sub rolls, hot dog buns, soft hoagie rolls, sandwich rolls, or slider buns will all work.

San Marzano Canned Tomatoes make incredible chopped tomatoes for the marinara sauce, I highly recommend this brand!

Tomato paste adds a deep level of rich concentrated sweet tomato flavor.

Kinds of Cheese: I used slices of mozzarella, it melts nicely and gets golden which looks great and will make your mouth water. You could use provolone, Havarti, cheddar, Monterey, or pepper jack cheese.

Crockpot Meatball Subs: For an easy marinara sauce shortcut, you can add a jar of spaghetti sauce to a crock pot or slow cooker with frozen meatballs. Add some Italian seasoning, diced onions, and garlic, and let it cook for 4 hours on low. Then just load the tender meatballs and sauce onto buns with cheese and put them under the broiler until melted and golden brown.

Build The Hot Sub Sandwiches

1. Place 3-4 meatballs on the sliced open baguette or roll, and cover with a few spoonfuls of marinara sauce.
2. Top with slices of mozzarella and place meatball sandwiches into the oven on a sheet pan under the broiler until the cheese melts and turns golden about 5 minutes. Keep an eye on these under the broiler so they don't burn!
3. Serve hot and enjoy. You can add some fresh salad, fruit, or a side of chips like tortillas or potato chips.
4. Store any extra meatballs or marinara sauce in an airtight container or use your food saver and tuck them in the freezer for a fast dinner.
