Making Cheesy Ground Beef Rice Casserole is a straightforward process when you follow these steps:

1. Preheat Your Oven: Set your oven to 350°F (175°C).
2. Brown the Beef: In a large skillet over medium heat, add olive oil. Once hot, add ground beef and cook until browned, about 5-7 minutes. Drain excess fat if necessary.
3. Add Onions and Garlic: Stir in the chopped onions and minced garlic. Cook for about 2-3 minutes until onions become translucent.
4. Combine Ingredients: In the skillet, add the uncooked rice, beef broth, cream of mushroom soup, mixed vegetables, onion powder, garlic powder, salt, and pepper. Stir well to combine.
5. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish. Spread it evenly.
6. Add Cheese: Sprinkle the shredded cheddar cheese evenly over the top of the mixture.
7. Bake: Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 25 minutes.
8. Uncover and Finish Baking: Remove the foil and bake for an additional 10-15 minutes or until the cheese is melted and bubbly.
9. Let It Rest: Take the casserole from the oven and let it cool for a few minutes before serving.
10. Garnish: If desired, sprinkle fresh parsley over the top for a colorful presentation.

By following these steps, you can create a delicious and cheesy ground beef rice casserole that will impress your family and friends.
