Detailed Directions and Instructions
Prepare the Meatballs
Preheat your oven to 400°F (200°C). In a large bowl, combine ground beef, breadcrumbs, egg, minced garlic, parsley, Italian seasoning, salt, and pepper. Use your hands to mix the ingredients until just combined.
Form and Bake Meatballs
Shape the mixture into meatballs, about 1-inch in diameter. Place the meatballs on a baking sheet lined with parchment paper. Bake for 20-25 minutes, or until they are cooked through and browned on the outside.
Prepare the Casserole Dish
While the meatballs are baking, grease a 9×13 inch casserole dish with cooking spray.
Layer the Ingredients
Spread a layer of marinara sauce at the bottom of the casserole dish. Once the meatballs are done, remove them from the oven and arrange them on top of the marinara sauce in the dish.
Add Bread and Cheese
Layer slices of bread over the meatballs. Use a combination of mozzarella and cheddar cheese to sprinkle evenly on top of the bread. Pour the remaining marinara sauce over the cheese and bread.
Top with More Cheese
Finish with additional cheese on top, ensuring it covers the sauce and bread completely.
Bake the Casserole
Cover the casserole dish with aluminum foil and bake in the preheated oven for 20 minutes. After 20 minutes, remove the foil and bake for an additional 10-15 minutes, until the cheese is melted and bubbly.
Let It Cool
Once cooked, remove the casserole from the oven and allow it to cool for about 10 minutes before serving.
