Delicious! Nine years later and people still love it! I always get asked to bring it to gatherings.

First, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
2. Cook the chopped onion and ground beef in a big pan over medium heat until the onion is soft and the meat is browned. Remove any surplus of fat.
3. Melt some butter in a 9×13 inch baking dish. Half of the thinly sliced potatoes should go on the bottom.
After the steak and onions are browned, spread them out equally over the potatoes.
Cream of mushroom soup, milk, salt, and pepper should be combined in a small dish. 5. Toss the potatoes and meat with half of the mixture.
6. Top with a quarter cup of crumbled cheddar cheese.
7. Once the cheese has been layered, add the remaining potatoes. Finally, pour the remaining soup liquid on top.
8. Bake for 30 minutes with the foil covering the dish.
9 After ten to fifteen minutes, take the foil off and top with the remaining cup of cheese. Bake until the potatoes are soft and the cheese is brown and bubbling.
