Ingredients:
- 4 large russet potatoes, peeled and thinly sliced
- 2 cups heavy cream
- 1 cup whole milk
- 2 cups shredded Gruyère cheese
- 1 cup shredded sharp cheddar cheese
- 3 cloves garlic, minced
- 1 teaspoon fresh thyme leaves
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon nutmeg
- 2 tablespoons unsalted butter, for greasing the baking dish
- Fresh parsley, chopped (for garnish)
Preparing the Cream Mixture
1. In a medium saucepan, combine the heavy cream and whole milk. Place it over medium heat and bring it to a gentle simmer. Be careful not to let it boil, as we just want to warm it up. 2. Once the cream mixture is warm, add the minced garlic, fresh thyme, salt, black pepper, and nutmeg. Stir well to combine all the flavors. Let it simmer for about 5 minutes, allowing the garlic to infuse its flavor into the cream. 3. After 5 minutes, remove the saucepan from the heat and set it aside to cool slightly. This will help the flavors meld together beautifully.Preparing the Potatoes
4. While the cream mixture is cooling, its time to prepare the potatoes. Using a mandoline slicer or a sharp knife, slice the peeled russet potatoes into thin, even slices, about 1/8 inch thick. This ensures they cook evenly and become perfectly tender. 5. As you slice the potatoes, place them in a large bowl of cold water to prevent browning. This also helps to remove excess starch, which can make the gratin gummy. 6. Once all the potatoes are sliced, drain them and pat them dry with a clean kitchen towel. This step is crucial for achieving that crispy texture we all love.Layering the Gratin
7. Preheat your oven to 375°F (190°C). While the oven is heating, grease a 9×13-inch baking dish with the unsalted butter, making sure to cover the bottom and sides well. 8. Begin layering the gratin by placing a single layer of potato slices at the bottom of the baking dish. Overlap them slightly to ensure even coverage. 9. Sprinkle a layer of Gruyère cheese over the potatoes, followed by a layer of sharp cheddar cheese. Dont be shy with the cheese; its what makes this dish so delicious! 10. Pour a portion of the cream mixture over the cheese layer, making sure to cover it evenly. Repeat this process: add another layer of potatoes, followed by cheese, and then cream. Continue layering until all the potatoes, cheese, and cream mixture are used up, finishing with a layer of cheese on top.Baking the Gratin
11. Once youve completed the layering, cover the baking dish with aluminum foil. This will help the potatoes cook through without burning the top. 12. Place the covered baking dish in the preheated oven and bake for 45 minutes. This initial baking time allows the potatoes to soften and absorb the flavors of the cream and cheese. 13. After 45 minutes, carefully remove the foil and continue baking for an additional 30-35 minutes, or until the top is golden brown and crispy. You can check for doneness by inserting a knife into the center; it should slide in easily if the potatoes are cooked through. 14. If you want an extra crispy top, you can broil the gratin for an additional 2-3 minutes at the end, but keep a close eye on it to prevent burning.Tips for Perfecting Your Gratin
– For added flavor, consider incorporating other herbs like rosemary or chives into the cream mixture.
