  • 2 pounds Russet potatoes, sliced
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 2 cups buttermilk
  • 2 tablespoons ranch seasoning
  • 2 cups shredded cheddar cheese, divided
  • 1 teaspoon pepper
  • 1 teaspoon salt


  • Preheat the oven to 375°F.
  • Slice potatoes into 1/4 inch thick rounds and layer flat in a large skillet. (I like to use a mandoline to get the slices as even as possible.)
  • In a saucepan, on medium-low heat, melt butter and add the flour to make a roux. Whisk constantly for 5 minutes.
  • As the roux gets darker, slowly add buttermilk, whisking as you pour.
  • Add ranch seasoning, black pepper, and salt. Remove from heat.
  • Stir in 1 cup shredded cheese (I like to switch to a spatula instead of whisk), making sure it is melted.
  • Pour the cheese sauce over the potatoes that are in the skillet.
  • Cover the skillet and cook for about an hour.
  • Uncover the potatoes, add the second cup of cheese, and bake for 25-30 more minutes, or until the cheese is browned.
