Creating Hobo Casserole with Ground Beef & Potatoes is simple. Follow these steps for a delicious outcome:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Cook the Ground Beef: In a large skillet, heat a drizzle of olive oil over medium heat. Add the ground beef and cook until browned. Drain excess fat if necessary.
3. Add Onion: Add the diced onion to the skillet with the cooked beef. Sauté for about 3-4 minutes, or until the onion becomes translucent.
4. Mix in Vegetables: Stir in the frozen mixed vegetables and Worcestershire sauce. Cook for an additional 2-3 minutes until the vegetables are heated through. Season with salt and pepper to taste.
5. Prepare the Casserole Dish: In a greased 9×13-inch baking dish, layer half of the sliced potatoes on the bottom.
6. Add Meat Mixture: Spread the ground beef and vegetable mixture over the potatoes, ensuring an even layer.
7. Layer Remaining Potatoes: Top the meat mixture with the remaining sliced potatoes.
8. Add Soup: Pour the cream of mushroom soup over the top layer of potatoes, spreading it evenly with a spatula.
9. Cover and Bake: Cover the dish tightly with aluminum foil and bake in the preheated oven for 45 minutes.
10. Uncover and Cheese: Remove the foil, sprinkle the shredded cheese on top, and return to the oven. Bake for an additional 15 minutes, or until the cheese is melted and bubbly.
11. Cool and Serve: Allow the casserole to cool for a few minutes before serving. Garnish with finely chopped fresh parsley if desired.
