Ingredients
- 2 pounds potatoes thinly sliced (see note 1)
- 3 tablespoons butter
- 2 tablespoons all-purpose flour
- 1 1/2 cups milk
- Salt and freshly ground black pepper
- 1 dash cayenne pepper
- 1 1/2 cups sharp cheddar cheese grated, divided (see note 2)
- paprika for garnish
Instructions
- Preheat oven to 350 degrees. Coat a 1-quart casserole dish with nonstick spray.
- In a small saucepan over medium-high heat, melt butter until foaming. Whisk in flour until cooked through, about 1 minute. Whisk in milk until smooth. Bring sauce to a boil, reduce heat, and cook until thickened.
- Stir in 1 cup cheese and season to taste with salt, pepper, and cayenne if using (I like 1 teaspoon salt , 1/2 teaspoon pepper, and a dash of cayenne).
- Layer half the sliced potatoes in bottom of prepared casserole dish. Top with half the cheese sauce. Layer the second half of potatoes and top with remaining cheese sauce.
- Add remaining 1/2 cup cheese on top and sprinkle with paprika, fresh chives, or thyme. Bake uncovered until heated through and the cheese and melted and browed, about 1 hour. Let stand 10 minutes before serving.

Notes
- Potatoes: Starchy russets are the best potatoes for Au Gratin potatoes.
- Cheese: A block of cheddar, shredded, seems to work best. Pre-shredded cheese can contain ingredients that prevent the cheese from melting smoothly. However, if you have a brand of shredded cheese that you rely on, go ahead and use it.
- Yield: This recipe makes 8 servings of Au Gratin potatoes, 1/2 cup per serving.
- Storage: Store leftovers covered in the refrigerator for up to 4 days.
- Slow Cooker: Prepare the liner of the pot as you would the casserole, then build the dish following the same instructions. Cover and cook on LOW for 8-10 hours. They don’t get as toasty or crispy on the top, but they’ll still taste delicious.
