Meatball Sub Casserole is a super easy casserole dish that tastes like a meatball sub but in casserole form. So good and a family favorite!
A FAMILY-FRIENDLY DINNER RECIPE
Raise your hand if you love meatball subs? Now how would you like to take all those flavors you love about a meatball sub and turn it into a casserole? Well, here ya go folks. This was the best tasting casserole I have had in a while. Not only was it super easy to make but the flavors blended so well together. The whole family loved it!
TIPS FOR MAKING MEATBALL SUB CASSEROLE:
- Homemade meatballs can be used in this dish; however, you want them to be fully cooked before adding them to this dish. This is a family friendly meal and using the pre-made meatballs really makes this quick to make.
- I would definitely serve this with a salad. Perhaps a big, green salad full of veggies and maybe topped with my Copycat Olive Garden Salad Dressing And for dessert, how about some No-Bake Strawberry Tiramisu?
- For a softer casserole, don’t toast the bread first. For a more firm casserole, toast the french bread slices first.
- For a twist, try using thawed garlic Texas toast rather than the Italian bread.
- Store any leftovers (covered) in the refrigerator for up to 3 days. You can also freeze leftovers, as long as it is properly wrapped, to protect against freezer burn, for up to 3 months.
- I haven’t tried freezing this meal before cooking. You might be able to do it but you’d have to definitely add onto baking time so you’ll have to play that by ear and check it periodically to make sure the middle is fully cooked.
INGREDIENTS NEEDED: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE)
- Italian bread – French bread can be used here. Basically you don’t want a bread that is too soft or it will get too soggy.
- cream cheese – it’s really important that your cream cheese be fully softened or it will end up with lumps in it when you try to mix it.
- mayonnaise – I know mayonnaise might seem weird in here but I need you to trust me on this. It adds additional creaminess and another layer of flavor that really makes this creamy filling taste so good!
- Italian seasoning – if you don’t have Italian seasoning, you can just combine a bit of dried basil and dried oregano.
- shredded mozzarella cheese – I just buy the pre-shredded mozzarella cheese but you can certainly shred yours by hand if you prefer.
- frozen meatballs – I go with the Italian style meatballs and they do need to be thawed. I usually just put the bag in my refrigerator the night before I make this. They actually thaw out pretty quickly so you can also leave them out on the counter for an hour or two as well.
- pasta sauce – I am a fan of Rao’s pasta sauces but I know they can be on the pricey side so use what you enjoy or can afford. It will still work great!
HOW TO MAKE MEATBALL SUB CASSEROLE:
Preheat oven to 350F degrees. Arrange bread slices in a single layer in an ungreased 9×13-inch baking dish. Just fill in any gaps with smaller bits of bread. I did have a couple slices of bread leftover since my loaf of Italian bread was pretty wide. I used those extra slices to make some garlic bread to serve with this.
In a bowl, combine cream cheese, mayonnaise and seasonings.
Spread mixture over bread slices.
Sprinkle with 1/2 cup of the shredded mozzarella cheese on top.
Gently mix together spaghetti sauce and meatballs.
Spoon this mixture the over cheese layer.
Sprinkle with remaining cheese.
Bake uncovered for 30-35 minutes. If you notice it is getting too brown, you can always cover the dish loosely with a bit of aluminum foil.
Allow to cool for a few minutes then slice and serve!

- For a firmer bread base, I recommend toasting the bread first. You can place the dish into the oven (on the broiler setting) and toast both sides. It should only take a minute or two.
- Note: frozen meatball packages come in varying sizes – anywhere from 18 ounces to 32 ounces. This recipe will accommodate most of those sizes. As long as you are grabbing a standard size bag and not a family size bag, it will work.
