- Preheat your oven to 375°F (190°C).
- In a large bowl, combine the ground beef, breadcrumbs, egg, Parmesan cheese, oregano, garlic powder, salt, and black pepper. Mix until well incorporated.
- Form the mixture into 1-inch meatballs and place them in a 9x13 inch baking dish.
- Pour the marinara sauce over the meatballs, making sure to cover them evenly.
- Sprinkle the shredded mozzarella cheese over the top.
- Bake for 30-35 minutes, or until the meatballs are cooked through and the cheese is melted and bubbly.
- Let the casserole cool for 5 minutes before serving.
Notes
The key to a successful meatball casserole lies in the science behind the ingredients. The egg and Parmesan cheese help the meatballs hold their shape and stay moist during the baking process. Baking the meatballs in the sauce, rather than simmering them on the stovetop, results in a more cohesive and flavorful dish. The oven's dry heat helps the sauce thicken and the mozzarella cheese to melt into a gooey, irresistible topping.
