Scalloped Potatoes Recipe

Ingredients

  • 4 tablespoons butter
  • 4 tablespoons flour
  • 1 medium onion chopped
  • 3-4 cloves garlic minced
  • 3 cups whole milk
  • 1 tablespoon chopped fresh thyme
  • 1 tablespoon chopped fresh parsley
  • ⅛ teaspoon cayenne pepper
  • Kosher salt and fresh ground black pepper to taste
  • 3 lbs Yukon Gold Potatoes thinly sliced

Instructions

  • Preheat oven to 350 degrees. Grease a 9×9 inch or not-deep 2-quart casserole dish. 
  • Melt the butter in a skillet over medium heat. Add the onion and cook until soft. Then reduce the heat and add the garlic, cooking for 1 minute while stirring constantly. 
  • Whisk in the flour and cook for 2 minutes. Slowly add the milk whisking to combine. Cook over low heat until thickened, whisking frequently. Do not let it boil. 
  • Whisk in about 2/3 of the thyme and parsley and all of the cayenne pepper. Season with kosher salt and fresh ground black pepper to taste. 
  • Layer 1/4 of the sliced potatoes in the bottom of a greased casserole dish. Pour 1/4 of the sauce over the top of the potatoes and spread it out with a spoon or spatula. Repeat the layers 3 more times ending with the cream sauce. Top with the remaining fresh herbs.
  • Cover the casserole with aluminum foil and bake for 45 minutes. Remove the foil and bake uncovered for 30-45 minutes or until the potatoes are tender and the casserole is bubbly on the edges. Turn the broiler on the last 1-2 minutes of cooking to brown the top. Sprinkle with fresh herbs.
