  1. Preheat oven to 425 degrees F (220 degrees C).
  2. Heat garlic bread with spread side up on a baking sheet in the preheated oven until warm and golden brown, 10 to 12 minutes. Set aside to cool.
  3. Reduce oven temperature to 350 degrees F (175 degrees C).
  4. Bring spaghetti sauce to a boil in a large pot. Place frozen meatballs into sauce. Reduce heat to low and simmer until meatballs are heated through, about 20 minutes.
  5. Tear garlic bread into bite-size pieces and spread into bottom of a 9x13-inch baking dish. Pour spaghetti sauce and meatballs over garlic bread, coating bread with sauce and distributing meatballs evenly. Spread mozzarella cheese over top in a layer, followed by a layer of Parmesan cheese.
  6. Bake casserole until cheese has melted, 20 to 25 minutes.

  • Cook's Note:
  • If you are using the frozen garlic toast that is already sliced packaged in boxes, I usually need 2 boxes. I have even used the frozen garlic bread with cheese, and it is great too!

I seriously wanted this to be as great as it sounded, but I thought, "hmm bread under sauce for 20+ minutes sound gloopey". I should have listened to my inner voice. My spaghetti sauce was delish, my homemade meatballs were delish--I should have served them BESIDE some garlic bread. I would cook & cut my garlic bread into bigger squares and serve them under the meatballs & sauce just no extra cooking step.

This was a quick and tasty meal. I am not sure how it will reheat as the bread was starting to get soggy, but overall very good. Next time I will add some peppers and onions. Thanks for a great recipe.

This is a great idea! Thanks! I added more flavor by making homemade meatballs and sauce and I mixed up some mozzarella cheese with some garlic herb spread and spread that on the bread (I used a baguette from the bakery-not the frozen bread). Baked it until the cheese was bubbly and then I topped that with the meatballs and the sauce and some more mozzarella along with a little bit of italian bread crumbs and then baked until the cheese melted. It was really quick, easy and delicious! Thanks!

I lined garlic bread around dish and put sausage with meatballs in center easy and great.

Loved it! I used jalapeno bagels instead of the french bread and added Frenches Fried onions to the top right before it was done. My son who doesn't normally like casseroles loved it

it was good, but bread got soggy and needed more flavor..maybe put a couple spices into it next time.
