* 1/2 teaspoon salt
* 1/4 teaspoon black pepper

### For the Casserole:

* 1 large loaf Italian bread (or similar crusty bread), sliced into 1-inch thick pieces
* 24-28 pre-made meatballs, cooked and ready to go (or use the homemade recipe above)

## Step-by-Step Instructions: Making the Meatball Sandwich Casserole

Now that we have all our ingredients ready, let’s walk through the steps of creating this mouthwatering casserole. We will start with how to make the meatballs from scratch but feel free to skip this section if you plan on using pre-made meatballs

### Part 1: Making the Homemade Meatballs (Optional)

If you’re using pre-made meatballs, skip to Part 2. But if you want to take your casserole to the next level, homemade meatballs are the way to go!

1. **Combine the Ingredients:** In a large bowl, combine the ground beef, ground Italian sausage, breadcrumbs, Parmesan cheese, parsley, minced garlic, egg, milk, Italian seasoning, salt, and pepper. Use your hands to gently mix everything together until just combined. Be careful not to overmix, as this can result in tough meatballs.
2. **Form the Meatballs:** Roll the mixture into 1-inch meatballs. You should get about 24-28 meatballs from this recipe.
3. **Cook the Meatballs:** There are several ways to cook the meatballs. Here are a few options:
* **Oven-Baked:** Preheat your oven to 400°F (200°C). Place the meatballs on a baking sheet lined with parchment paper. Bake for 20-25 minutes, or until the meatballs are cooked through and browned.
* **Pan-Fried:** Heat a tablespoon of olive oil in a large skillet over medium heat. Add the meatballs to the skillet in batches, being careful not to overcrowd the pan. Cook, turning occasionally, until the meatballs are browned on all sides and cooked through.
* **Simmered in Sauce:** Add the meatballs directly to the marinara sauce in a large pot or Dutch oven. Bring to a simmer and cook for at least 30 minutes, or until the meatballs are cooked through and the sauce has thickened slightly. This method infuses the meatballs with even more flavor.

### Part 2: Assembling the Meatball Sandwich Casserole

Now that your meatballs are cooked and ready, it’s time to assemble the casserole!

1. **Prepare the Bread:** Lightly brush both sides of each slice of Italian bread with olive oil. This will help the bread become golden and toasty in the oven. Alternatively, for a softer bread base, skip toasting.
2. **Arrange the Bread:** Arrange the bread slices in a single layer at the bottom of a 9×13 inch baking dish. You may need to tear or cut some of the bread slices to fit snugly in the dish. They should cover the entire bottom of the dish as much as possible.
3. **Add a Layer of Sauce:** Spread about half of the marinara sauce evenly over the bread slices. Make sure to cover all the bread so it doesn’t dry out during baking.
4. **Arrange the Meatballs:** Arrange the cooked meatballs evenly over the sauce-covered bread. Distribute them so that each bite will have a meatball.
5. **Top with Remaining Sauce:** Pour the remaining marinara sauce over the meatballs, making sure to coat them well.
6. **Add the Cheese:** Sprinkle the mozzarella cheese evenly over the sauce and meatballs. Then, sprinkle the Parmesan cheese over the mozzarella cheese.
7. **Bake the Casserole:** Preheat your oven to 375°F (190°C). Cover the baking dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for another 15-20 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
8. **Let it Rest:** Let the casserole rest for 10-15 minutes before slicing and serving. This will allow the cheese to set slightly and make it easier to cut.
9. **Garnish and Serve:** Garnish with fresh basil leaves, if desired. Serve hot and enjoy!

## Tips and Variations for the Best Meatball Sandwich Casserole

* **Use High-Quality Ingredients:** The better the quality of your ingredients, the better the flavor of your casserole. Choose good-quality ground beef, Italian sausage, marinara sauce, and cheese.
* **Don’t Overmix the Meatball Mixture:** Overmixing the meatball mixture can result in tough meatballs. Gently combine the ingredients until just combined.
* **Toast the Bread:** Toasting the bread slices before assembling the casserole will help prevent them from becoming soggy. Brush with garlic butter for extra flavor.
* **Add Vegetables:** Sauté some chopped onions, bell peppers, or mushrooms and add them to the casserole for extra flavor and nutrients.
* **Use Different Cheeses:** Experiment with different types of cheese, such as provolone, fontina, or Asiago.
* **Make it Spicy:** Add a pinch of red pepper flakes to the meatball mixture or sauce for a spicy kick.
* **Make it Gluten-Free:** Use gluten-free breadcrumbs and gluten-free bread to make this casserole gluten-free.
* **Use Different Types of Meat:** Try using ground turkey or ground chicken instead of ground beef and Italian sausage.
* **Add a Creamy Layer:** For an extra decadent casserole, spread a layer of ricotta cheese or creamy pesto between the sauce and the cheese.
* **Different Bread Options:** Consider using ciabatta rolls, hoagie rolls, or even garlic bread slices instead of Italian bread.
