Ingredients
  

  • 1 lb lean ground beef
  • 1 small onion diced
  • 2-3 medium Russet potatoes peeled and thinly sliced
  • Salt and pepper to taste
  • 1 can (10.75 oz) condensed cream of mushroom soup
  • 1/8 cup milk or up to 1/2 cup for saucier finish
  • 1 tsp Worcestershire sauce optional
  • 4-6 slices American cheese or 1 cup shredded cheddar
  • 1 1/2 cups French-fried onions

Equipment

  • 8x8 or 9x9-inch baking dish
  • aluminum foil
  • small mixing bowl
  • whisk

Method
 

  1. Preheat oven to 350°F (175°C).
  2. Press raw ground beef evenly into the bottom of an 8x8 or 9x9-inch baking dish. Season generously with salt and pepper.
  3. Sprinkle diced onion evenly over the beef.
  4. Layer thinly sliced potatoes over the onions, overlapping slightly. Season with additional salt and pepper.
  5. Place cheese slices over the potatoes, covering as much surface area as possible.
  6. In a small bowl, whisk together cream of mushroom soup, milk, and Worcestershire sauce (if using) until smooth.
  7. Pour soup mixture evenly over the cheese layer, spreading to the edges.
  8. Cover dish tightly with aluminum foil. Bake for 1 to 1 1/2 hours, or until potatoes are fork-tender.
  9. Remove foil and sprinkle French-fried onions evenly over the top.
  10. Bake uncovered for 5 minutes until onions are golden brown and crispy.
  11. Let rest for 5 minutes before serving.

Notes

Storage: Refrigerate leftovers in an airtight container for up to 4 days. Reheat in microwave or oven at 350°F for 20 minutes covered. Freezes well for up to 3 months. Make-Ahead: Assemble completely, cover, and refrigerate up to 24 hours before baking. Add 10-15 minutes to baking time if starting from cold. Substitutions: Use ground turkey or chicken instead of beef. Swap American cheese for cheddar, Monterey Jack, or pepper jack. Use cream of chicken or celery soup in place of mushroom.
