Meatball Sub Casserole

Winter is STILL here, can you believe it? Oh. My. Goodness. Supposedly Punxsutawney Phil didn’t see his shadow this year but I’m telling you…

I feel like it will never end!

Seriously though, I know it’s the end of February and March is right around the corner. This is the hardest part of the season. You’re waiting for spring, but March is usually the snowiest month and by now.

I’m seriously over it. You can relate right?

That’s why we need more casserole recipes in our life! Delicious recipes that are easy to make and will warm you up on a cold day! Lasagna Casserole, Baked Spaghetti Casserole or Cheesy Chicken Noodle Casserole all great choices so I’m adding one more – Meatball Sub Casserole!

This is a hearty, yummy casserole perfect for those cool days that seem to be here to stay.

I knew when I saw this I had to try it. It comes together so fast and easy. I used pre-made meatballs, toasted the bread a little so it would stay firm. I did wonder when I was making this if I was going to end up with a soggy mess.

This is also what my mom asked when I told her about this! I’m proud to report that it doesn’t turn into a soggy mess!

Casserole Recipes

My family loves casseroles and so do I! Although we refer to them as “Hot Dishes” since we are from Minnesota.

It’s funny how I’ve had to change my lingo since I started this blog ?

What do I need to make Meatball Sub Casserole

loaf french bread
cream cheese
mayonnaise
Italian seasoning
pepper
mozzarella cheese
frozen meatballs
pasta sauce

What are the three main parts of a casserole?

Meat, sauce and cheese! Heavenly huh? But a casserole needs the right dish. A great casserole dish will be oven safe. Some are deep, others are more shallow. Metal is usually lighter, ceramic can be heaven once it’s filled.

I like a dish that is pretty enough to go from the oven right to the table. Here are some of my favorites!

For all you farmer’s wives out there this would be a PERFECT casserole to bring out to the meal and would have the guys coming back for seconds. I know if you are anything like us you are always on the look out for new meals to bring out!

How to make Meatball Sub Casserole

Preheat the oven.
Arrange slices of bread in one layer in the casserole dish. If there are gaps, fill them in with smaller chunks of bread.
Next combine cream cheese, mayonnaise and seasonings.
Spread over bread slices. Sprinkle with shredded mozzarella cheese.
Combine the spaghetti sauce and meatballs. Spoon over cheese. Sprinkle with remaining cheese.
Bake until hot and bubbly!

Can I add a second layer of everything in a large roaster to feed a crowd? Or will that make it really soggy?

  I think it would work since the bread is toasted but I can’t guarantee this!

I’m going to use texas garlic toast instead of french bread and air fryer toaster oven instead of oven. Any suggestions for these changes?

  I would bake the garlic toast before putting it on the bottom.
