Ingredients

  • 4 large russet potatoes, thinly sliced
  • 1 medium onion, finely chopped
  • 3 cloves garlic, minced
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 2 cups milk
  • 1 1/2 cups shredded cheddar cheese
  • 1/2 cup shredded Parmesan cheese
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon ground nutmeg
  • 1 teaspoon fresh thyme (or 1/2 teaspoon dried thyme)
  • 1/2 cup breadcrumbs (optional for topping)
  • Fresh parsley, chopped (optional for garnish)

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish or a similar-sized casserole dish.
  2. Prepare Potatoes: Peel and thinly slice the potatoes using a mandoline or a sharp knife to about 1/8 inch thick. Set aside.
  3. Make the Sauce:
    • In a medium saucepan, melt the butter over medium heat. Add the chopped onion and garlic, and sauté until soft and fragrant, about 3-4 minutes.
    • Stir in the flour and cook for another 1-2 minutes until it forms a paste (roux) and is lightly golden.
    • Gradually whisk in the milk, ensuring there are no lumps. Continue to whisk until the mixture thickens, about 5 minutes.
    • Remove from heat and stir in the cheddar cheese and Parmesan cheese until melted and smooth.
    • Season with salt, black pepper, nutmeg, and thyme. Adjust seasoning to taste.
  4. Assemble:
    • Arrange half of the sliced potatoes in an even layer in the prepared baking dish.
    • Pour half of the cheese sauce over the potatoes, spreading it evenly.
    • Repeat with the remaining potatoes and cheese sauce, ensuring all potatoes are covered with the sauce.
  5. Top and Bake:
    • If using breadcrumbs, sprinkle them evenly over the top.
    • Cover the dish with aluminum foil and bake in the preheated oven for 45 minutes.
    • Remove the foil and bake for an additional 25-30 minutes, or until the potatoes are tender and the top is golden and bubbly.
  6. Serve: Allow the dish to cool for about 10 minutes before serving. Garnish with freshly chopped parsley if desired.
