Make incredibly rich and cheesy creamy scalloped potatoes that everyone will ask for again. This delicious side dish recipe gives you tender potatoes in a velvety sauce, perfect for weeknight dinners or holiday gatherings.

Ingredients

Scale
  • 3 lbs Russet potatoes, peeled and thinly sliced (about 1/8 inch thick)
  • 4 tablespoons unsalted butter
  • 1/4 cup all-purpose flour
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon nutmeg
  • 2 cups whole milk
  • 1 cup heavy cream
  • 2 cups shredded sharp cheddar cheese, divided
  • 1/2 cup grated Parmesan cheese

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  2. Place the thinly sliced potatoes in a large bowl. Set aside.
  3. In a medium saucepan, melt the butter over medium heat. Whisk in the flour, salt, pepper, and nutmeg. Cook, stirring constantly, for 1 minute.
  4. Gradually whisk in the milk and heavy cream until the mixture is smooth. Bring the sauce to a simmer, stirring often, until it thickens enough to coat the back of a spoon, about 5 to 7 minutes.
  5. Remove the sauce from the heat. Stir in 1 1/2 cups of the cheddar cheese and all of the Parmesan cheese until melted and smooth. This is your velvety cream sauce.
  6. Pour half of the cheese sauce over the sliced potatoes and gently toss to coat every slice.
  7. Transfer the coated potatoes to the prepared baking dish, arranging them in even layers.
  8. Pour the remaining half of the sauce evenly over the potatoes in the dish.
  9. Sprinkle the remaining 1/2 cup of cheddar cheese over the top layer.
  10. Bake uncovered for 50 to 60 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly.
  11. Let the rich potato bake rest for 10 minutes before serving.

Notes

  • For scalloped potatoes and ham ideas, layer 1 cup of diced cooked ham between the potato layers before adding the final cheese topping.
  • To achieve thin, even slices, use a mandoline slicer if you have one. This helps the potatoes cook uniformly.
  • If the top browns too quickly during baking, loosely cover the dish with aluminum foil for the last 15 minutes.
