Ingredients

  • 3 pounds Russet or Yukon Gold potatoes, peeled and sliced ⅛-inch thick
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 2 cups whole milk or half-and-half
  • 1/2 cup heavy cream (optional, for extra richness)
  • 2 cups shredded sharp cheddar cheese (divided)
  • 2 cloves garlic, minced (or 1 teaspoon garlic powder)
  • 1/2 onion, finely diced (or 1 teaspoon onion powder)
  • 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 oven to 375°F (190°C). Grease a 9×13-inch baking dish.
  2. Peel and slice potatoes thinly (about ⅛-inch thick). Place in cold water to prevent browning; drain and pat dry before using.
  3. In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1–2 minutes to form a roux.
  4. Gradually whisk in milk and cream (if using), stirring constantly until the sauce thickens, about 4–5 minutes.
  5. Stir in garlic, onion, salt, and pepper. Remove from heat and mix in 1 cup of the shredded cheese until melted and smooth.
  6. Layer half of the sliced potatoes in the prepared baking dish. Pour half of the cheese sauce over the top.
  7. Repeat with remaining potatoes and cheese sauce. Sprinkle the remaining 1 cup of shredded cheese evenly on top.
  8. Cover with foil and bake for 30 minutes. Remove foil and bake for an additional 25–30 minutes until potatoes are tender and top is golden and bubbly.
  9. Let rest for 10 minutes before serving. Garnish with paprika, thyme, or parsley if desired.

Notes

  • Add cooked bacon, sautéed leeks, or jalapeños for variations.
  • Use a blend of cheeses like Gruyère or Parmesan for extra depth.
  • To make gluten-free, use a gluten-free flour blend for the roux.
  • To freeze: assemble but don’t bake. Wrap tightly and freeze for up to 2 months. Thaw before baking as directed.
