Ingredients Equipment Method Notes

Ingredients
  

  • 2.5 lb Yukon gold potatoes (about 8–9 medium-sized)
  • 2 lb lean ground beef
  • 1 cup sweet yellow onion, finely diced
  • 1 tbsp minced garlic
  • 10.5 oz cream of mushroom soup (Great Value or similar)
  • 1 cup half and half
  • 1 tbsp onion powder
  • 1.5 tsp kosher salt
  • 1 tsp freshly cracked black pepper
  • 3 cups Colby Jack cheese, freshly shredded and divided

Equipment

  • 9x13-inch baking dish
  • large saucepan or Dutch oven
  • Mixing bowl
  • Whisk
  • knife and cutting board
  • Foil

Method
 

  1. Thinly slice the potatoes (about ⅛-inch thick) and place them in water to prevent browning while prepping.
  2. Preheat oven to 350°F (177°C). Lightly grease a 9×13-inch baking dish and set aside.
  3. In a large saucepan or Dutch oven, cook ground beef, diced onions, and minced garlic over medium-high heat until browned. Drain excess oil.
  4. In a mixing bowl, whisk together cream of mushroom soup, half and half, onion powder, kosher salt, and black pepper until smooth.
  5. Drain potato slices. Layer one-third of the potatoes in the baking dish, followed by one-third of the beef mixture and ¾ cup cheese. Pour a third of the sauce over the top.
  6. Repeat with another layer of potatoes, meat, cheese, and sauce.
  7. Finish with a final layer of potatoes and meat. Pour remaining sauce over and top with 1½ cups of shredded cheese.
  8. Cover the dish with foil and bake for 1 hour and 10 minutes. Remove foil and bake uncovered for another 20 minutes until bubbly and golden.
  9. Let the casserole rest for 15 minutes before serving.

Notes

For a richer flavor, try substituting part of the half and half with heavy cream. You can also add sliced mushrooms or green peas for extra texture. Leftovers reheat beautifully in the oven the next day.
