Rate This Recipe

We’re taking a simple bag of Trader Joe’s Italian meatballs and turning it into a delicious meal of homemade meatball subs! This Trader Joe’s meatball recipe is EASY, filling, family-friendly, and made with just 5 ingredients. While I’m using ingredients from Trader Joe’s to make this meatball sub recipe, you don’t have to shop at Trader Joe’s, these ingredients are available at any store!

I am a big fan of meatball subs, but I rarely made them at home – until now! I’m not sure what took so long, they’re so easy to make, especially this version that leans on prepared ingredients from Trader Joe’s (Hi, Trader Joe’s frozen Italian meatballs!) , these easy meatball subs don’t take much effort at all.

What’s in a Meatball Sub?

We’re keeping the ingredients simple in these homemade meatball subs:

  • Meatballs – There are a few Trader Joe’s frozen meatballs to choose from! There are Beef, Turkey, Party (Mini) Size, and Meatless varieties of meatballs at most Trader Joe’s, but I typically just stick with my favorite. Out of all of the meatballs at TJ’s, the Trader Joe’s Italian meatballs (beef) is my favorite and the one I usually buy. While I love making my own turkey and quinoa meatballs, the turkey meatballs from Trader Joe’s are not my favorite (I think they end up a bit dry and tough!), so I usually stick with the beef ones.
  • Best Bread for Meatball Sub: I prefer Italian bread for meatball subs, and instead of serving it sub-style, I like to toast the slices (with garlic butter for extra flavor!) so that they don’t get too soggy with the sauce. Using sliced bread also makes this meatball & marinara sub MUCH easier to eat. Sliced sourdough bread would also be a good option and Trader Joe’s has a pretty good sourdough loaf.
  • Meatball Sub Sauce: In my opinion, there’s only one sauce for easy homemade meatball subs…Trader Joe’s marinara! You could use pizza sauce or tomato sauce in a pinch, but marinara is best. If you don’t want your sub to get too soggy, you can also leave it off the sandwich and serve it on the side as a dipping sauce.
  • Meatball Sub Toppings: As with most toppings, you can keep it simple, or go all out. In this homemade meatball sub recipe I kept the meatball sub toppings simple. In addition to the basics (Trader Joe’s Italian meatballs, marinara sauce, and cheese) red pepper flakes, grated parmesan cheese, and thinly sliced basil or Italian parsley would add a little extra flavor.
