  1. Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes. Drain and cool. Peel and slice potatoes into thin rounds.
  2. Melt butter in a saucepan over medium heat. Saute green onions in hot butter until tender, 3 to 4 minutes. Stir sour cream, condensed chicken soup, Cheddar cheese, and salt into onion mixture until completely combined.
  3. Preheat oven to 375 degrees F (190 degrees C).
  4. Arrange potato slices in the bottom of an 8x8-inch baking pan. Pour cheese sauce over potatoes.
  5. Bake in the preheated oven until brown around the edges, about 45 minutes.

This was perfect, but I agree with a little less butter. The flavors were just what I was looking for. I added ham cubes to it and sent it home for my daughter and her family!

I made this for Christmas dinner. Everyone loved it, even the picky eaters. Was asked for the recipe. Leftovers were also good. (There wasn't too much left.)
