💡 Let’s Make Things Easy, okay?

Make delicious Italian Meatball Sub Sandwiches the easy way with frozen meatballs and jarred pasta sauce. 

Choose between homestyle, Italian-style, or turkey meatballs for your recipe. 

Any jarred spaghetti sauce will do, but I like to use Prego Traditional.

And add a touch of McCormick Perfect Pinch Italian Seasoning for extra flavor. 

To save time, heat the sauce and meatballs in your slow cooker. 

Cook on low for 3-4 hours or high for 2-3 hours. 

Since the meatballs are pre-cooked, just make sure they are heated through. 

For easy cleanup, cover your baking sheet with aluminum foil and give it a spray of nonstick cooking spray. 

No worries about the cheese spilling over – cleaning up will be a breeze. Enjoy these mouthwatering Italian subs with minimum effort and maximum taste!

You can use any jarred spaghetti sauce that you like.

I usually go with Prego Traditional pasta sauce then kick it up with a teaspoon or so of Italian seasoning, like the McCormick Perfect Pinch Italian Seasoning.

That’s my secret to many great Italian dishes.

To save time, the sauce and meatballs can be heated in your Crock-pot.

Try cooking on low for 3-4 hours or high for 2-3 hours.

The frozen meatballs are already pre-cooked so you’ll just want to make sure they are heated through.

🔑 Key to Success #1 – Use Frozen Meatballs for Convenience

The great thing about using frozen meatballs is that they’re already cooked and seasoned to perfection. 

Choose between homestyle, Italian-style, or turkey meatballs for your recipe. 

Not only do frozen meatballs save you time and effort, but they also deliver on taste. 

They’re made with high-quality ingredients and are packed with all the flavors you crave in an Italian sub sandwich.

Whether you prefer traditional beef and pork meatballs or opt for a lighter chicken or turkey version, the frozen aisle has got you covered. 

All you have to do is pop them in the oven, heat them up on the stovetop over low or medium heat, or make crockpot meatballs in your slow cooker.

And let’s not forget about the juicy, tender texture that hot meatballs bring to the table. 

It’s the perfect complement to the crusty bread and melty cheese that make Italian subs so irresistible.

​If you have leftover meatballs, they’ll be perfect in this easy meatball sub recipe.

Or you can make your own homemade meatballs using any of your favorite meatball recipes.

🔑 Key to Success #2 – Use Your Favorite Spaghetti Sauce

Using your favorite tomato sauce is the second key to revolutionizing your meatball sandwich recipe. 

Just like the frozen meatballs, the right sauce can take your sandwich to a whole new level of deliciousness. 

The rich tomato flavors in your favorite jar of spaghetti sauce will infuse every bite of your Italian sub, bringing a burst of tanginess to the sub party.

The acidity and sweetness of jar of marinara sauce will balance out the savory meatballs and creamy cheese, creating a flavor combination that will make your taste buds sing. 

Don’t be afraid to experiment with different varieties of store-bought marinara and find the one that perfectly matches your personal preference.

🔑 Key to Success #3 – Melty Cheese and Toasty Bread

When it comes to choosing the right cheese for your Italian sub, you have a myriad of options. 

Fresh mozzarella is a classic choice, with its creamy texture and mild flavor that pairs beautifully with the other ingredients. 

Provolone is another popular choice, providing a slightly sharper taste that cuts through the richness of the meatballs and sauce.

Simply place slices of provolone cheese over the meatballs and sauce then toast as directed. 

The bread is the foundation of any great sandwich, and when it comes to Italian subs, toasting is key. 

A lightly toasted roll adds a delightful crunch and brings out the flavors of the fillings even more. 

Whether you prefer a soft, fluffy roll or a crusty baguette, make sure you toast up your sub before serving.

In a pinch, you can throw together your Italian subs on any hoagie buns or even toasted hot dog buns.

Top the sub rolls with 4-5 meatballs and extra sauce then layer on your cheese. 

The meatball sandwiches need to bake in a 400 degree F oven for about 10-15 minutes, just until the sandwich rolls start to crisp up and the cheese melts.

What to Serve with Italian Meatball Subs

A well-chosen side dish can complement the flavors of the sub and elevate your overall dining experience.

One classic option to serve with Italian meatball subs is a fresh green salad. 

The crispness of the greens provides a refreshing contrast to the rich and savory flavors of the meatballs and is perfect topped shaved Parmesan cheese. 

If you’re looking for something heartier to serve alongside your Italian meatball subs, consider making a batch of crispy oven-baked fries. 

The crispy exterior and fluffy interior of the fries make for the perfect contrast to the soft and tender meatballs. 

You can sprinkle them with some Italian seasoning or grated Parmesan to tie in the flavors of the sub.

For those who enjoy a touch of elegance with their sandwiches, serving Italian meatball subs with a side of roasted vegetables is a winning choice. 

Roasting vegetables like zucchini, bell peppers, and eggplant brings out their natural sweetness and adds a delightful smoky flavor. 

Drizzle them with some extra virgin olive oil, sprinkle with salt and pepper, and roast them until they are caramelized and tender.

No matter which side dish you choose, this meal is sure to be one that the entire family will ask for again and again.
