Description

These Creamy Au Gratin Potatoes are the ultimate comfort food, featuring thinly sliced potatoes layered with a rich, cheesy cream sauce. Baked until golden and bubbly, this dish is perfect as a hearty side for holiday dinners, family gatherings, or any time you’re craving something warm and indulgent.

Ingredients

Units Scale
  • 4 large russet potatoes, peeled and thinly sliced
  • 2 cups shredded sharp cheddar cheese
  • 1 cup grated Gruyère cheese (optional for extra richness)
  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 2 cups whole milk, warmed
  • 1 cup heavy cream
  • 2 cloves garlic, minced
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon paprika (optional for garnish)
  • Fresh thyme or parsley for garnish (optional)

Instructions

  1. Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
  2. Prepare the sauce: In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute. Stir in the flour and cook for 1–2 minutes until lightly golden.
  3. Add the dairy: Slowly whisk in the warm milk and heavy cream, stirring constantly to avoid lumps. Cook until the sauce thickens, about 3–5 minutes. Season with salt and pepper.
  4. Add the cheese: Remove the sauce from heat and stir in 1½ cups of the cheddar and ½ cup of Gruyère (if using) until melted and smooth.
  5. Layer the potatoes: Arrange half of the sliced potatoes in the prepared baking dish. Pour half of the cheese sauce over the potatoes. Repeat with the remaining potatoes and sauce.
  6. Top and bake: Sprinkle the remaining cheddar and Gruyère on top. Lightly dust with paprika for color if desired. Cover with foil and bake for 45 minutes.
  7. Finish baking: Remove the foil and bake for an additional 20–25 minutes until the top is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
  8. Garnish and serve: Let the dish rest for 10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Notes

  • For a deeper flavor, add caramelized onions or cooked bacon between the layers.
  • You can substitute Yukon Gold potatoes for a creamier texture.
  • Make ahead: Assemble the dish up to 1 day in advance and refrigerate. Add 10–15 minutes to the baking time if baking from cold.
