  • Cutting board
  • Mandoline (optional)
  • Y-peeler (optional)


  • 6 medium Yukon Gold potatoes or yellow potatoes, peeled and thinly sliced
  • 1 small onion sliced, optional
  • 3 Tablespoons Butter
  • 3 Tablespoons Flour
  • 2 cups Whole Milk
  • 1 cup Heavy Cream
  • 2 cups Sharp Cheddar Cheese shredded (divided into 2 portions)
  • 1 teaspoon Seasoned Salt
  • salt to sprinkle between layers of potatoes, about ½ teaspoon each time
  • pepper to sprinkle between layers of potatoes, about ½ teaspoon each time, plus extra for cream sauce


  • Preheat your oven to 350°F. Grease a 9 by 13-inch baking dish and set it aside. Melt butter in a large saute pan over medium-high heat, then add flour. Whisk until a thick paste forms. Slowly add milk, then heavy cream, whisking until the mixture is thick and creamy. Finally, add cheese, seasoned salt, and pepper. Mix until combined to create your béchamel sauce.

  • Use a Y-peeler to peel your potatoes. They are easy to hold and make it easy to quickly peel potatoes.
  • For perfectly sliced potatoes, use a mandoline. A mandoline makes it easy to slice your potatoes to the exact same size, quickly.
  • If you do not have a y-peeler or a mandoline, use a paring knife to peel and cut your potatoes. Peel them facing away from yourself to avoid cutting yourself.
  • Do not boil the potatoes ahead of time. This will make mushy, overcooked potatoes.
  • Add heavy cream and whole milk slowly, while continuously whisking
