Ingredients:

  • 3 tablespoons butter
  • 1 small onion, finely diced
  • 1 clove garlic, minced or grated
  • 1 teaspoon of chopped fresh thyme (or substitute with 1/2 teaspoon of dried thyme)
  • 3 tablespoons flour (use gluten-free flour if needed)
  • 1 1/2 cups milk
  • 1 1/2 cups Gruyère cheese, shredded
  • 1 pinch nutmeg (optional)
  • Salt and pepper, to taste
  • 4 pounds potatoes, peeled and thinly sliced

Instructions:

  1. Preheat the Oven:
    • Preheat your oven to 375°F (190°C).
    • Coat a 9×13-inch baking dish with butter or a non-stick spray to prevent sticking.
  2. Prepare the Cream Sauce:
    • In a medium saucepan, melt the butter over medium heat.
    • Add the finely diced onion and cook until softened, about 4-5 minutes.
    • Add the minced garlic and thyme, and cook for another minute until fragrant.
  3. Make the Roux:
    • Dust the onions and garlic with flour, ensuring an even coating.
    • Stir well to combine, cooking for about 1 minute until the flour turns a light golden color.
  4. Add the Milk:
    • Slowly add the milk while continuously whisking to avoid any lumps.
    • Keep cooking the sauce, stirring often, until it reaches a thicker consistency, which should take around 3 to 4 minutes.
  5. Incorporate the Cheese:
    • Reduce the heat to low and slowly add the shredded Gruyère cheese to the sauce, stirring until the cheese is melted and the sauce is smooth.
    • Incorporate a dash of nutmeg (if desired) and adjust the flavor with salt and pepper to your liking.
    • Remove from heat.
  6. Layer the Potatoes:
    • Arrange half of the sliced potatoes evenly in the prepared baking dish.
    • Drizzle half of the cheese sauce over the potatoes, ensuring it is distributed uniformly.
    • Layer the remaining potatoes on top, and finish by pouring the rest of the cheese sauce over them, making sure all the potatoes are covered.
  7. Bake:
    • Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and continue baking for an additional 30-40 minutes, or until the potatoes are tender and the top is golden brown and bubbling.
  8. Rest and Serve:
    • Let the Potato Gratin rest for 10 minutes before serving to allow the sauce to set. Serve warm as a delicious side dish with your favorite main course.
