  • 5 med potatoes about 6 cups cubed
  • 1 cup sour cream
  • 1 10.5-ounce can cream of mushroom soup canned or homemade
  • 8 ounces ham diced, 1 3/4 cups
  • 1 cup cheese shredded, Colby Jack or Cheddar
  • 1/2 tsp garlic powder
  • 1/4 tsp onion salt
  • 2 cups cornflakes
  • 1/4 cup butter melted


  1. Preheat the oven to 350º F.
  2. Put cubed potatoes in a 4 qt. pot and cover with cold water. Put on stove over medium high heat and boil. Once they come to a boil, turn on the timer for about 10 minutes.

  3. While the potatoes are boiling, mix the sour cream, soup, ham, cheese, garlic powder, and onion salt in a medium bowl. Set aside.
  4. In a small bowl, mix the cornflakes with the melted butter. Set aside.
  5. Poke a few potatoes with a fork to check for doneness. If they are done, drain them and pour in an 8×8 baking dish. Put the cheesy mixture on top and stir around so all the potatoes are covered.
  6. Then add the cornflakes on top of the potatoes. You can put more cheese on top of the cornflakes if desired. I like it with just the cornflakes, though.
  7. Bake for 35-40 minutes or until cheese is melted and bubbly. Let stand for about 5-10 minutes before serving.
