Put your slow cooker to work and take the guesswork out of what to serve for dinner by making turkey meatball subs using store-bought turkey meatballs.

Have you ever arrived home at the end of the day and wondered what you would serve for dinner? 

My family is busy. I have two teenage boys who are heavily involved in afterschool sports and activities.

Dinner sometimes is rushed. While we would all like to sit down together for a meal, sometimes it’s not possible.

Many nights I have one kid arriving home as the other is leaving for his practice.

For the subs, I made a simple rich tomato sauce for the crock pot before adding frozen meatballs. 

It’s that easy!

I prefer to make my own homemade pasta sauce for this meatball sandwich recipe because its so much more flavorful.

I allow the meatballs to slow simmer for a few hours and this easy dinner idea is ready when we arrive home. 

I don’t always have time to make my favorite meatball recipe from scratch, so frozen are the perfect solution.

What I love about this amazing recipe is that it serves double duty.

Turkey meatball subs one night for dinner and the next we reheat and serve what’s left over a bed of pasta.

Frozen meatballs come in all different flavors and many are gluten free.

These meatballs are packed with protein which is important for the growing teenagers in the house.

The whole family will love this delicious meatball sub recipe.

Ingredients

Pick up these simple ingredients from your local grocery store.

Meatballs. Your choice of beef or turkey, fresh or frozen.

Hoagie rolls. They offer a bit more room than hot dog buns. Grab your favorite sub rolls from the bread aisle.

Canned tomatoes. Grab several cans of your favorite brand of fire roasted and crushed tomatoes. Or pick up a jar of marinara sauce instead.

Onion. My favorite is sweet vidalia, but white or yellow work well.

Garlic. Fresh or jarred minced garlic adds great flavor to the sauce.

Parmesan cheese. Sprinkle grated parm cheese over the top of each sub.

Italian seasonings.  Purchase already mixed or use basil, oregano and parsley individually. 

Cheese slices.  Mozzarella and provolone are my favorites for turkey for great flavor. If using beef, try cheddar.

How to make meatball sandwiches

  1. Add the onion, garlic and tomatoes to a crockpot on low heat. 
  2. Mix in the Italian seasonings. 
  3. Add the meatballs on top of the sauce and simmer for 3 to 4 hour. 
  4. Add in the Parmesan cheese and stir until the cheese has melted.
  5. Assemble the subs, adding layers of sauce, meatballs and slices of provolone cheese and mozzarella. 
  6. Place the subs under the broiler. Look for melted cheese and browning buns as a sign to remove from the oven.

What kind of meatballs should I use?

If you don’t have time to make homemade meatballs, the next best thing is fresh pre-packaged tender meatballs from the meat department.

After that, frozen works best. I like to keep a package at all times in the freezer that way I don’t have to make a special trip to the store.

Select ground beef or ground turkey meatballs.

I like to use the turkey meatballs because they are lower in fat. 

And they’re perfect for this easy meatball sub recipe.

The sauce is an easy concoction of fire roasted and crushed tomatoes.

The right mix of spices and Parmesan cheese adds true Italian seasoning to the sauce.

Should you thaw frozen meatballs before cooking?

There is no need to thaw frozen meatballs first. The simmering sauce will keep the meatballs in perfect shape.
