What Kind of Potatoes Work Best for Gratin?

For the creamiest texture with just the right bite, choose starchy varieties like Russets or Yukon Golds. These types hold up well during baking, soaking up the garlicky cream while still keeping their shape.

How To Make the Crispy Parmesan and Gruyere Potato Gratin

Step 1: Prep and Preheat

Preheat your oven to 375°F (190°C). Butter a baking dish generously and set it aside.

Step 2: Slice the Potatoes

Using a mandoline or sharp knife, thinly slice the potatoes to about 1/8 inch thick. Uniform slices ensure even cooking.

Step 3: Make the Garlic Cream Sauce

In a small saucepan, combine heavy cream, minced garlic, salt, pepper, and a few thyme sprigs. Heat gently until warm and fragrant (do not boil). Remove thyme before using.

Step 4: Assemble the Layers

Arrange a layer of potatoes on the bottom of the dish. Pour over a bit of the warm cream sauce, sprinkle with a mix of Parmesan and Gruyere. Repeat layers until ingredients are used up, finishing with a cheese topping.

Step 5: Bake Until Golden

Cover with foil and bake for 40 minutes. Remove foil and continue baking for 20 more minutes until the top is golden brown and bubbly.

Step 6: Rest Before Serving

Let the gratin rest for 10 minutes before serving. This allows the layers to set and makes slicing easier.

How to Serve and Store Crispy Parmesan and Gruyere Potato Gratin

Serve this gratin warm right out of the oven, when the cheese is perfectly melted and the top is crisp. It’s an excellent choice for dinner parties, family holidays, or cozy Sunday meals.

Store any leftovers tightly covered in the fridge for up to 4 days. Reheat in the oven to maintain the crispy top, or microwave in a pinch.
