Why We Love This Meatball Sub Bake
I have to tell you that there is nothing like using homemade meatballs in this easy weeknight dinner and I encourage you to try it at least once. Our Perfect Meatballs use ground beef or a ground beef pork blend to make the most incredible meatballs and I kid you not.
Ground meat, panko or bread crumbs, and a few other ingredients make these the best meatballs which is why they’re called perfect!
Whatever sauce you choose to use consider simmering it for a time after adding some chopped, sauteed vegetables.
I grab a skillet, add some oil and allow it to heat up over medium heat. The oil must be shimmering or when a drop of water is flicked in it dances or sizzles.
Then add your vegetables of choice, about half a cup or as much or as little as you desire. Saute until tender and add to your tomato sauce before adding it to your meatball sub bake.
The secret to this recipe being so simple is the refrigerated biscuit dough. It stands up to being baked with all the sauce in this recipe, and it adds a unique flavor and texture that makes this recipe something extra tasty that the family will love.
History of the Meatball Sandwich
I want to take a moment to talk about a North American favorite, the meatball sandwich. You might be asking yourself why a meatball sandwich would be termed as a North American favorite when it obviously come from Italy. Well, that’s the first thing we’re covering. Meatball sandwiches aren’t actually an Italian invention. At least not technically.
Believe it or not, no one knows exactly where or when this sandwich was invented, but most agree that it was sometime during the turn of the 20th century and that it was most definitely born in the United States.
It’s universally agreed that the meatball sandwich is an Italian-American invention first created by Italian immigrants. This is why the classic sandwich is made up of an Italian roll filled with meatballs, red sauce, and mozzarella cheese or provolone cheese.
Of course, these days you can find all manner of meatballs and cheeses used in meatball sandwiches. You can also find, you guessed it, meatball sandwich variations like this Italian meatball bake.

This recipe is so easy that I not only make it for weeknight dinners, but I’ve also been known to whip up a batch for potlucks, as well. I firmly believe that making this dish is always the right decision when you need something to feed a crowd.

Tips for Making the Meatball Sub Casserole
You’ll find the full printable recipe for this super easy meatball sub bake below, but there are a few simple tips to keep in mind. This is a super easy dish, as most casseroles are, but you’ll want to read over the tips for this Italian meatball bake carefully to ensure that you create the best final product possible.
Bake the Meatballs Before Adding Them to the Casserole
You do have to actually cook the meatballs for a short time before adding them to the rest of the Italian meatball casserole recipe. The directions below are for frozen meatballs so if you’re using homemade meatballs, you’ll have to adjust accordingly.
Coating the Biscuits
Since the canned biscuits will be layering the bottom of the dish, you want to be certain to coat them in the seasoning. They’re going to provide the “crust” as well as a delicious texture. They really do become more like Italian bread than biscuits when they’re cooked at the bottom of this casserole.
How to Know When the Casserole is Done Cooking
Since the meatballs are already cooked at this point, you just need to be certain that the bottom layer of biscuits is cooked all the way through. This should take about 40 minutes of time for this to happen.
Your cheese is melted nicely too.
If you find that the biscuits aren’t done cooking, just pop them back in the oven and cook in 5-minute intervals until the biscuits are done.
Fun Topping Ideas
Don’t forget that you can add your favorite toppings to this recipe as well. I love to add parsley, but you can add more cheese, chopped onions, some more tomato sauce, or even some bits of crumbled-up bacon. It’s totally up to you as to what you want to add as toppings.
Vegetables to add to Tomato Sauce
The great thing about this sub recipe is that you can add in as much, or as little as you want. This gives you the flexibility to easily change up the taste and flavor fast and with minimal effort on your part.
Some simple ideas on how to get more veggies into your diet are shown below. These veggies can all be added to the tomato sauce after they’re ideally sauteed.
- sweet bell peppers or hot peppers
- green beans
- yellow squash
- jarred roasted red peppers
Can I use homemade meatballs for this recipe?
You can if you have the time! I love that this recipe uses frozen meatballs but you can easily make homemade meatballs as well. I’ve actually done it both ways but I always use this method when I’m short on time – and it tastes delicious, too.
What side dishes go well with this delicious meatball bake?
I always whip up a delicious side salad recipe with this dish as well as some garlic bread or cheesy breadsticks. Since the casserole is hearty and full of flavor, you don’t really need to add anything too heavy to this dish.
I will say though that it’s important to be certain to have dessert! Don’t forget to make Andes Mint Cupcakes with Irish Buttercream Frosting as the perfect cupcake dessert to pair with this dish.
