Ingredients
1 pound (450g) lean ground beef
1 medium yellow onion, chopped
4 medium Russet potatoes, peeled and thinly sliced (approx. 1/8 inch thick)
1 can (10.5 oz) condensed cream of mushroom soup
½ cup sour cream
¼ cup milk
1 teaspoon salt (divided)
½ teaspoon black pepper
1 teaspoon garlic powder
1 ½ cups shredded Cheddar cheese
Optional: Chopped fresh parsley or green onions for garnish
Instructions
1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray.
2. In a large skillet over medium-high heat, cook the ground beef and chopped onion until the beef is browned and the onions are soft. Drain any excess fat.
3. Season the beef mixture with half of the salt, the pepper, and the garlic powder. Spread this mixture evenly across the bottom of the prepared baking dish.
4. Arrange the thinly sliced potatoes in an even layer over the ground beef. (Overlap them slightly if necessary). Sprinkle the remaining salt over the potatoes.
5. In a medium bowl, whisk together the condensed cream of mushroom soup, sour cream, and milk until smooth.
6. Pour the creamy soup mixture evenly over the layer of potatoes. Use a spatula to spread it out to the edges.
7. Cover the dish tightly with aluminum foil. Bake for 60 to 75 minutes, or until the potatoes are fork-tender.
8. Remove the foil and sprinkle the shredded Cheddar cheese over the top.
9. Return to the oven (uncovered) and bake for another 5-10 minutes, or until the cheese is melted and bubbly.
10. Let the casserole rest for 5-10 minutes before serving. Garnish with parsley if desired.
Notes
Potato Tips: Slice your potatoes thinly and uniformly so they cook evenly. If they are too thick, they may remain crunchy even after an hour of baking.
Variations: You can swap the ground beef for ground turkey or sausage. For extra veggies, add a layer of frozen peas or corn between the meat and potatoes.
Soup Substitute: If you aren’t a fan of mushroom soup, Cream of Chicken or Cream of Celery soup works perfectly in this recipe.
Crispy Topping: For a crunch, sprinkle French-fried onions (like French’s) over the cheese during the last 5 minutes of baking.
