Creating a delicious Cheesy Loaded Meatloaf Casserole with Vegetables is easy when you follow these simple steps:

1. Preheat the oven to 350°F (175°C). Grease a 9×13-inch casserole dish.
2. Prepare the Meat Mixture: In a large bowl, combine the ground beef, breadcrumbs, 1 cup of shredded cheese, mixed vegetables, chopped onion, minced garlic, eggs, Worcestershire sauce, oregano, salt, and black pepper. Mix well until all ingredients are fully incorporated.
3. Form the Meatloaf: Transfer the meat mixture into the prepared casserole dish. Shape it into a loaf form, ensuring it is evenly spread.
4. Add Marinara Sauce: Pour the marinara sauce over the top of the meatloaf. Spread it evenly to ensure every bite is flavorful.
5. Top with Cheese: Sprinkle the remaining cheese on top of the marinara sauce, adding a beautifully cheesy crust.
6. Bake: Place the casserole in the preheated oven and bake for 35-45 minutes. The meatloaf should be cooked through and the cheese should be bubbly.
7. Rest: Once baked, remove the casserole from the oven and let it rest for about 10 minutes before slicing. This helps the loaf hold together better.
8. Slice and Serve: Cut into portions and serve warm, ensuring everyone gets a piece of the cheesy goodness.

These steps ensure you’ll have a mouthwatering casserole ready to impress everyone at the table.
