Ingredients Equipment Method Notes

Ingredients
  

  • 2 lbs russet or Yukon Gold potatoes peeled and thinly sliced
  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 2 cups milk whole or 2%
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ¼ teaspoon garlic powder optional
  • 1 ½ cups shredded cheddar cheese
  • ½ cup shredded Parmesan cheese
  • 1 teaspoon Dijon mustard optional, for extra flavor
  • 2 tablespoons chopped fresh parsley optional, for garnish

Equipment

  • 9×13-inch baking dish
  • Saucepan
  • Whisk
  • Knife or mandoline
  • Mixing spoon

Method
 

  1. Preheat Oven – Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish.
  2. Make the Cheese Sauce – In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1–2 minutes to form a roux. Gradually whisk in milk until smooth. Add salt, pepper, garlic powder, and Dijon mustard. Cook until slightly thickened, 3–4 minutes. Remove from heat and stir in 1 cup cheddar cheese until melted.
  3. Layer Potatoes – Arrange half of the sliced potatoes in the prepared baking dish. Pour half of the cheese sauce over the potatoes. Repeat with remaining potatoes and cheese sauce.
  4. Add Topping – Sprinkle remaining cheddar and Parmesan evenly over the top.
  5. Bake – Cover with foil and bake for 45 minutes. Remove foil and bake another 15 minutes until cheese is bubbly and golden.
  6. Serve – Let cool for 5 minutes. Garnish with fresh parsley if desired and serve warm.

Notes

Make Ahead: Assemble the dish a day ahead, refrigerate, then bake when ready to serve.
Cheese Variations: Swap cheddar for Gruyère, mozzarella, or Monterey Jack for different flavors.
Add-Ins: Layer in cooked bacon, caramelized onions, or sautéed mushrooms for extra richness.
Thin Slices: Use a mandoline for evenly sliced potatoes to ensure even cooking.
