How to Make Truffle Potato Gratin with Gruyere & Smoked Cheddar
-
Preheat the oven to 375°F (190°C). This ensures that your gratin will cook evenly, resulting in a beautifully golden top as it bakes.
-
Peel and slice the white washed potatoes thinly, about 1/8 inch thick. A mandoline would work wonders here for uniformity and even cooking.
-
Combine the milk, thickened cream, nutmeg, salt, pepper, thyme, sage, and garlic in a saucepan. Heat gently over medium until warm but not boiling, allowing the herbs to infuse their flavors.
-
Layer half of the sliced potatoes in a generously greased baking dish. Pour half of the creamy milk mixture over the potatoes, then sprinkle half of the grated cheeses on top.
-
Repeat the layering process with the remaining potatoes, milk mixture, and cheeses. This creates the perfect balance of creamy potato and melted goodness throughout the dish.
-
Drizzle with white truffle oil, allowing it to sink into the layers slightly for that gourmet touch. A little goes a long way!
-
Bake in the preheated oven for 50-60 minutes, until the top is golden brown and the potatoes are tender when pierced with a fork. The scent will be heavenly!
Optional: Garnish with fresh thyme leaves for an added pop of flavor and color.

Make Ahead Options
These Truffle Potato Gratin with Gruyere & Smoked Cheddar are perfect for meal prep! You can slice the potatoes and prepare the creamy milk mixture up to 24 hours in advance, storing them separately in the refrigerator to keep the potatoes from browning. Simply layer the potatoes and filling as directed, but cover with plastic wrap or aluminum foil until you’re ready to bake. When you’re set to serve, just preheat your oven, assemble the gratin, and bake for about 50-60 minutes until golden and bubbly. This approach not only saves you precious time on busy nights but ensures that your dish is just as delicious as if made fresh!

Expert Tips for Truffle Potato Gratin
Even Cooking: Ensure your potatoes are cut uniformly; aim for 1/8 inch thickness. This prevents some pieces from being undercooked while others are overdone.
Infuse Flavors: Allow the milk mixture to warm without boiling. This helps the herbs and garlic release their flavors, enhancing the overall taste of your truffle potato gratin.
Watch the Cheese: Grate your cheeses freshly for the best melt. Pre-packaged cheese can contain anti-caking agents that affect the creaminess of your gratin.
Truffle Oil Caution: Drizzle white truffle oil sparingly after baking. Too much can overpower the dish, so one-half tablespoon is just right for that gourmet touch.
Golden Top: Keep an eye on the baking time, as ovens can vary. Aim for a golden brown crust, which indicates perfect crispness.

Truffle Potato Gratin with Gruyere & Smoked Cheddar Recipe FAQs
What type of potatoes should I use for the Truffle Potato Gratin?
Absolutely! For the best results, it’s recommended to use starchy white washed potatoes like Yukon Gold or Russets. These varieties have the right amount of starch, which helps create that creamy, luxurious texture you’re aiming for. Avoid waxy potatoes, as they won’t break down properly and may result in a firmer gratin.
How should I store my leftover Truffle Potato Gratin?
Very! Store your leftovers in an airtight container in the fridge for up to 3 days. If you’re keen to enjoy it later, you can freeze it too. Just ensure it’s completely cooled, then wrap it tightly in plastic wrap and aluminum foil. This prevents freezer burn and preserves flavor!
Can I freeze Truffle Potato Gratin?
Absolutely! For freezing, individual portions work best. After cooking, let the gratin cool completely, then slice it into servings. Wrap each portion tightly in plastic wrap, then place them in a freezer-safe container or bag. It can be stored for 2-3 months. When you’re ready to enjoy, thaw overnight in the fridge before reheating.
What should I do if my gratin isn’t browning on top?
Very! If your gratin isn’t browning, a simple solution is to increase the oven temperature to 400°F (200°C) for the last 10-15 minutes of baking. You can also broil it for a couple of minutes—just keep a close eye on it to prevent burning. A golden top is a foolproof sign of deliciousness!
