Creating this delicious Hobo Casserole is a breeze if you follow these steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).

2. Cook the Beef: In a large skillet, heat the olive oil over medium heat. Add the ground beef and onions, cooking until the meat is browned and the onions are translucent. Drain excess grease.

3. Season the Beef: Stir in garlic powder, salt, and black pepper. Mix to combine well.

4. Layer the Ingredients: In a greased 9×13 inch casserole dish, begin layering the ingredients. First, place the sliced potatoes evenly across the bottom. Next, add the cooked beef mixture, followed by the frozen mixed vegetables. Finally, spread the cream of mushroom soup over the top.

5. Cover and Bake: Cover the casserole dish with aluminum foil. Bake in the preheated oven for 30 minutes.

6. Add Cheese: After 30 minutes, remove the foil and sprinkle the shredded cheddar cheese over the top. Return to the oven and bake for an additional 5-10 minutes, or until the cheese is melted and bubbly.

7. Let It Rest: Once done, remove from the oven and let it rest for 5 minutes before serving.

These straightforward steps will ensure you achieve a flavorful Hobo Casserole perfect for family dining.
