For the Garlic Bread Layer:
1 baguette, sliced
1/4 cup unsalted butter, melted
2 cloves garlic, finely chopped
1 teaspoon Italian seasoning
Salt and pepper, to taste
Casserole Toppings:
3 cups marinara sauce
2 cups shredded mozzarella cheese
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 180°C (350°F) while you prepare the ingredients.
Step 2: Make the Meatballs
In a mixing bowl, combine:
Ground beef
Chopped garlic
Breadcrumbs
Egg
Chopped parsley
Salt and pepper
Mix thoroughly until all ingredients are well incorporated. Shape the mixture into small, evenly sized meatballs.
Step 3: Cook the Meatballs
Heat 1 tablespoon of oil in a large skillet over medium heat.
Cook the meatballs in two batches, about 6–7 minutes per batch, until they’re browned on all sides and cooked through. Remove from the pan and drain excess oil.
Step 4: Prepare the Garlic Bread Base
Grease a large baking dish. Layer the bottom with slices of baguette.
In a small bowl, mix together:
Melted butter
Garlic
Italian seasoning
Salt and pepper
Brush this mixture generously over the bread slices in the pan.
Step 5: Assemble the Casserole
On top of the garlic bread:
Sprinkle 1 cup of shredded mozzarella
Pour half of the marinara sauce
Add the cooked meatballs
Cover with the remaining marinara sauce
Top with the remaining 1 cup of mozzarella cheese
Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake for 12–15 minutes, or until the cheese is melted and bubbly.
For extra golden cheese, broil for an additional 2–3 minutes at the end.
