Ingredients
 

  • 2 pounds potatoes, peeled and very thinly sliced

For the Cheese Sauce

  • 1 tablespoon butter
  • 1 shallot
  • 1 tablespoon garlic, minced
  • 1 1/2 cups whole milk
  • 1/2 cup heavy cream
  • 1 cup sharp cheddar cheese, shredded
  • 1/4 cup parmesan cheese
  • 1 1 ounce Ranch seasoning packet

Topping

  • 1 cup sharp cheddar cheese, shredded

Instructions
 

  • Preheat oven to 400 degrees F. Spray an 11 x 7-inch baking dish with cooking spray and set aside.
  • In a deep skillet or sauce pan combine the butter over medium heat, add the shallot and garlic and sauté until fragarant. Stir in the milk, heavy cream, cheeses, and Ranch seasoning.
  • Bring the mixture to a simmer, stirring occasionally. When the mixture has thickened remove from the heat and set aside.
  • Layer the thinly sliced potatoes in a greased casserole dish. Pour the cheddar sauce over the potatoes and tilt back and forth so it is evenly distributed. Cover the dish with foil and bake 25 minutes.
  • Remove the foil and add the remaining cheese. Bake an additional 10-15 minutes until the potatoes are fork tender and the cheese is golden.
  • Allow the dish to rest at least 10 minutes before serving.

Notes

Cooking time may vary slightly based on the thickness of your potatoes. To check potatoes, stick a fork or knife for tenderness.
