Yield

1 9×13-inch casserole

Ingredients

  • 8 — Idaho or russet potatoes, peeled

  • 2 (10.5 ounce) cans — cream of chicken soup

  • 2 cups — sour cream

  • ½ cup — butter, melted

  • 1 cup — chopped green onion

  • 2 ½ cups — shredded Cheddar cheese

  • 1 cup — crushed corn flakes, or more if needed

  • ¼ cup — butter, melted

Directions

  • Preheat oven to 350 degrees F (175 degrees C).
  • Place potatoes into a large saucepan, cover with water, and bring to a boil. Reduce heat to medium-low and simmer potatoes until tender but not mushy, about 15 minutes. Drain and let cool. Cut potatoes into 1-inch thick slices.
  • Whisk cream of chicken soup, sour cream, 1/2 cup melted butter, and green onions in a bowl until thoroughly combined. Whisk cheese into the sauce. Mix corn flake crumbs with 1/4 cup melted butter in a separate bowl.
  • Spread a thin layer of sour cream sauce into the bottom of a 9×13-inch glass baking pan. Spread a layer of potato slices over sauce, followed by a thick layer of sauce. Continue layers, ending with sauce. Sprinkle corn flakes mixture over the top of the casserole.
  • Bake in the preheated oven until casserole is bubbling and the corn flakes topping is crisp, about 45 minutes.
