Creating your Cheesy Loaded Meatloaf Casserole with Vegetables is a straightforward process when you follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 375°F (190°C). This ensures that your casserole will cook evenly.

2. Prepare Vegetables: If using fresh vegetables, chop them finely and set them aside. For frozen vegetables, ensure they’re thawed.

3. Mix Meat Mixture: In a large bowl, combine the ground beef, breadcrumbs, chopped onion, bell pepper, minced garlic, egg, Worcestershire sauce, salt, pepper, oregano, and ½ cup of shredded cheddar cheese. Mix until all ingredients are well incorporated.

4. Add Vegetables: Fold in the mixed vegetables to the meat mixture, ensuring they are evenly distributed.

5. Transfer to Baking Dish: Lightly grease a 9×13-inch baking dish and transfer the meat mixture, pressing it down evenly.

6. Prepare Topping: In a separate small bowl, whisk together the milk and ketchup until smooth. Pour this mixture over the meatloaf in the baking dish.

7. Top with Cheese: Scatter the remaining shredded cheddar cheese over the top, adding extra for a cheesier finish if desired.

8. Bake: Place the baking dish in the preheated oven. Bake for 1 hour, or until the meat is fully cooked and reaches an internal temperature of 160°F (71°C).

9. Let Rest: Once done, remove from the oven and allow it to rest for 5-10 minutes before slicing. This helps firm up the casserole for easier serving.

10. Slice and Serve: Use a sharp knife or spatula to slice into squares and serve warm.

As you follow these steps, you’ll find that making Cheesy Loaded Meatloaf Casserole with Vegetables is not only simple but also incredibly rewarding.
