Amazing ingredients selection
- Potatoes: Go for Yukon Gold or Russet types for their starch content that creates the ideal texture. Look for firm ones without sprouts and smooth skin.
- Heavy cream: Pick full-fat cream with at least 30% fat for that unbeatable richness. Farm-fresh cream adds subtle notes that make your gratin even tastier.
- Cheese: Traditional Gruyère brings nutty flavors that work perfectly with potatoes. Grate it yourself instead of buying pre-shredded for better melting.
- Garlic: Pick firm, fresh cloves with no green shoots. French or pink garlic offers milder, more complex flavor than standard white varieties.
- Nutmeg: Try to use a whole nutmeg and grate it right when cooking to release all those aromatic compounds that gently flavor your mixture.
Step-by-step guide
- Getting ready:
- First, heat your oven to 180°C and butter your baking dish generously. This key step stops potatoes from sticking and makes serving easier. Using a traditional clay dish helps spread heat evenly and gives that rustic charm when you bring it to the table.
- Potato prep:
- Carefully peel your potatoes, removing all eyes and blemishes. The secret to great gratin is even slices. A mandoline set to 3mm works best for perfectly uniform slices that'll cook evenly throughout.
- Cream mixture:
- In a thick-bottomed pot, pour in your heavy cream and milk. Add finely chopped garlic and a touch of freshly grated nutmeg. Warm it gently without boiling so the flavors can develop and infuse the cream. This step subtly flavors the whole dish.
- Building your gratin:
- Lay down your first potato layer in the dish, slightly overlapping them like fish scales. Add a little salt and pepper, then pour some of your cream mixture on top. Keep going until you've used everything up, finishing with the flavored cream.
- Baking it right:
- Cover your dish with foil for the first part of baking. This lets the potatoes cook evenly in the steam. Then take off the foil for the final cooking time to get that signature golden top that makes this dish so special.

Wonderful serving ideas
This gratin pairs beautifully with roasted meats like crispy-skinned farm chicken or herb-crusted leg of lamb. For a lighter meal, just add an endive salad with walnuts and walnut oil dressing. For special occasions, I serve it in individual ramekins for a fancier presentation that always impresses my guests.
Tasty variations
You can make this Dauphinois your own based on what you like or what's in your kitchen. For a heartier version, add smoked bacon bits between the potato layers. Cheese lovers will enjoy adding aged Comté or Beaufort for stronger flavor. If you want more herbs, try infusing the cream with fresh thyme sprigs and a bay leaf, just take them out before you build the layers.

Smart storage
To keep your gratin at its best, let it cool completely before covering and putting it in the fridge. It'll stay good for up to three days. When reheating, it's better to use an oven preheated to 150°C for about 20 minutes rather than a microwave which would make the texture too soft. If you want to freeze it, do so before the final baking, then cook it straight from frozen by adding 15 minutes to the original time.
Frequently Asked Questions
- → What kind of potatoes work best for potato gratin?
- Yukon Gold or Russet potatoes are ideal because they're starchy, allowing them to soak up the cream while holding their shape.
- → Can I prepare potato gratin ahead of time?
- Yes, assemble it up until baking, then store it in the fridge for up to 24 hours. Just bake it cold, adding 10–15 minutes to the cooking time.
- → How can I stop the cream from spilling over during baking?
- To catch any spillover, place the dish on a baking sheet. Also, don’t fill it to the brim—leave about an inch of space.
- → Can potato gratin be frozen?
- Freezing isn’t ideal as the cream might split when thawed. Instead, keep it refrigerated and enjoy it within three days.
- → Is there a lighter alternative to cream for the gratin?
- Mix light cream with milk for fewer calories, though the dish will be less rich. Avoid using only milk as it will make it watery.
