Servings 8 servings


  • 3 tbsp. butter
  • 3 tbsp. flour
  • 1 ½ tsp. salt
  • 2 c. milk
  • 1 c. cheddar cheese shredded
  • 5 c. potatoes thinly peeled and sliced
  • ½ c. onion chopped


  • Begin by heating your oven to 350°F and preparing a 2-qt. baking dish by spraying it with cooking spray. Next, melt the butter in a saucepan over low heat. When the butter is melted, whisk in the flour, salt, and a dash of pepper until it's smooth. Then slowly add in the milk while continuing to whisk and allow the mixture to come to a boil. Let the mixture boil for a few minutes so that it thickens before stirring in the cheese and allowing it to melt.
  • Once the cheese has melted, remove from heat and stir in the potatoes and onion until combined. Put the mixture into your prepped baking dish and cover with foil before baking for an hour. After an hour, remove the foil and bake another 30-40 minutes or until the potatoes are tender. Top with additional cheese if desired and serve!
