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:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
