Ingredients

  • 2 kg russet or Yukon Gold potatoes, peeled and thinly sliced (about 3 mm thick)
  • 4 tablespoons unsalted butter
  • 4 tablespoons all-purpose flour
  • 3 cups whole milk
  • 1 cup heavy cream
  • 1 ½ teaspoons salt
  • 1 teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon ground black pepper
  • ¼ teaspoon ground nutmeg
  • 1 ½ cups shredded cheddar cheese
  • ½ cup grated mozzarella cheese
  • ¼ cup grated Parmesan cheese

Instructions

  1. Preheat oven to 180°C (350°F). Lightly grease a large baking dish with butter.
  2. In a saucepan over medium heat, melt the butter. Add flour and whisk for 1 minute until smooth and bubbling.
  3. Slowly whisk in the milk, then add the cream. Continue whisking until thickened, about 4–5 minutes.
  4. Add salt, garlic powder, onion powder, black pepper, and nutmeg. Remove from heat and stir in half the cheddar cheese until melted.
  5. Layer half of the sliced potatoes in the baking dish. Pour half the sauce evenly over the potatoes.
  6. Repeat with remaining potatoes and sauce. Sprinkle remaining cheddar, mozzarella, and Parmesan cheese over the top.
  7. Cover loosely with foil and bake for 60 minutes. Remove foil and bake another 30–40 minutes until golden and bubbly.
  8. Let rest for 10 minutes before serving.

Notes

  • Slice potatoes evenly to ensure even cooking.
  • For extra flavor, add herbs like thyme or swap cheddar for Gruyère.
  • To prevent curdling, avoid boiling the sauce after adding cheese.
  • This dish can be assembled a day ahead and baked fresh before serving.
