Ingredients
  

  • 4 russet potatoes sliced thin
  • 1 sweet onion sliced thin
  • 3 tablespoons butter
  • 2 tablespoons garlic minced
  • ¼ cup flour
  • 1 ¾ cup chicken broth
  • 2 tablespoons mayonnaise
  • ¾ cup heavy cream
  • 1 cup shredded cheddar cheese + more for topping
  • 2 teaspoons pepper
  • 2 teaspoons fresh parsley finely chopped

Instructions
 

  • Preheat the oven to 350°F. Thinly slice the potatoes to be about a quarter to a half-inch in thickness. I used a mandolin slicer, but this can also be done by hand (it will just take some extra time!).
  • Spray a baking dish with cooking oil, then arrange the potatoes in the pan so they are just overlapping.
  • In a medium frying pan, melt the butter, then add the garlic. When the garlic is fragrant, add the flour and whisk constantly.
  • Slowly pour in the chicken broth and whisk until a creamy sauce has formed. Add the mayonnaise and heavy cream, followed by the cheddar cheese, pepper, and parsley.
  • Arrange the sliced onions on top of the potatoes as a second layer. Pour half of the creamy sauce over the potatoes and onions. Arrange another layer of potatoes, then pour the remaining cheese sauce over the top.
  • Bake for one hour. Remove at the hour mark and sprinkle a generous amount of cheddar cheese over the top of the baked potatoes, then return to the oven for an additional 10 minutes. Serve while hot for a great side dish to any meal. Enjoy!
