Why You’ll Love This Traditional Potato Gratin

This potato gratin isn’t just delicious; it’s versatile and deeply satisfying.

The creamy layers deliver comfort food bliss, while the baked cheese crust gives it the wow factor your guests will remember.

What Kind of Potatoes Work Best for Gratin?

The ideal potato for gratin is starchy and firm. Yukon Golds are a popular choice because they hold their shape well and offer a naturally buttery flavor. Russet potatoes also work beautifully, creating that melt-in-your-mouth softness while absorbing the cream for a rich, full-bodied texture.

Ingredients for the Traditional Potato Gratin

A few humble ingredients come together to make this incredible dish. What matters most is their quality and balance.

Potatoes: Choose starchy varieties like Yukon Gold or Russet for the perfect soft, tender bite.

Heavy Cream: This is where the richness comes in. The cream bubbles and thickens around the layers, creating that velvety finish.

Garlic: Just a clove or two infuses the cream with subtle depth and warmth.

Gruyère Cheese: Melts smoothly and brings a nutty, slightly sharp note that elevates the gratin.

Salt & Pepper: Simple seasoning is key to letting the ingredients shine.

Butter: Used to grease the dish and dot the top for extra golden crispiness.

How To Make the Traditional Potato Gratin

Step 1: Prep the Potatoes

Peel and thinly slice the potatoes. Aim for slices about 1/8 inch thick. A mandoline makes this job quicker and more consistent.

Step 2: Infuse the Cream

In a saucepan, heat the heavy cream with minced garlic, salt, and pepper. Bring to a gentle simmer and let it infuse for a few minutes.

Step 3: Layer the Dish

Butter a baking dish generously. Layer the potatoes evenly, overlapping slightly. After each layer, spoon some of the warm cream and a sprinkle of cheese.

Step 4: Add the Final Touches

Once all the layers are in, pour any remaining cream over the top. Scatter the last bit of cheese and dot with small pieces of butter.

Step 5: Bake to Perfection

Bake uncovered in a preheated oven at 375°F (190°C) for 60 to 70 minutes, or until the top is golden brown and a knife slides easily through the center.

Serving and Storing Potato Gratin

This recipe feeds about six people as a side dish, and it’s always a hit at family dinners or festive gatherings. Serve it hot from the oven, ideally after letting it sit for 10 minutes to firm up a little. The flavors intensify as it rests, making it even better.

If you have leftovers, they store well in the refrigerator for up to 3 days. Reheat in the oven at 350°F to revive that crusty top, or microwave if you’re in a hurry (though the top may soften).
