Easy Hobo Casserole is a hearty, one-dish meal that layers ground beef, sliced potatoes, carrots, and green beans in a creamy mushroom sauce. It’s baked until the vegetables are tender and topped with melted cheese for a comforting finish. Perfect for busy weeknights, this casserole serves six and delivers classic meat-and-potatoes flavor with minimal prep.
In a large skillet, brown ground beef with the onion until the beef is fully cooked. Drain off excess grease.
In a large mixing bowl, combine the beef, sliced potatoes, carrots, and green beans. Add to a greased 9 x 13-inch baking dish and spread out evenly.
In the same bowl you mixed the veggies and meat together, whisk the cream of mushroom soup, milk, salt, pepper, and Italian seasoning. Pour the mixture over everything in the dish.
Cover the dish tightly with foil and bake for 45 minutes.
Remove the foil, sprinkle cheese over the top, and bake uncovered for another 15 minutes, or until cheese is bubbly and vegetables are fork-tender.
