1small yellow onionfinely diced
1½cupsgrated cheddar cheese
1poundapprox. 450 g lean ground beef
½cupfull-fat milk
½teaspoongranulated garlic
½teaspoonground black pepper
½teaspoonkosher salt
1can10.5 oz condensed cream of mushroom soup
Fresh chopped parsleyoptional, for garnish
Instructions
Preheat your oven to 375°F (190°C). Prepare a 9x13-inch baking dish by lightly greasing it with oil or non-stick spray.
In a medium skillet set over moderate heat, cook the ground beef along with the diced onion. Stir occasionally until the beef is fully browned and the onions are tender. Drain any rendered fat from the pan. Season the mixture evenly with salt, black pepper, and garlic powder.
In a separate small bowl, combine the condensed mushroom soup and the milk. Whisk thoroughly until the mixture is smooth and lump-free.
In the greased baking dish, layer half of the potato slices across the bottom. Distribute half of the beef and onion mixture evenly over the potatoes. Drizzle half of the creamy soup sauce over the top. Repeat the layering process with the remaining potatoes, beef mixture, and sauce.
Sprinkle the shredded cheddar cheese uniformly over the final layer.
Cover the dish securely with aluminum foil and place it in the oven. Bake for 60 to 70 minutes, or until the potatoes are soft and easily pierced with a fork.
Remove the foil and continue baking for an additional 10 to 15 minutes, allowing the cheese on top to turn golden and slightly crisp.
After baking, let the casserole stand at room temperature for 5 to 10 minutes before cutting into portions. If desired, finish with a sprinkle of freshly chopped parsley before serving.
Notes
For enhanced flavor, try adding a pinch of smoked paprika or Italian seasoning to the ground beef during cooking.
