Delia Smith Dauphinoise Potatoes Recipe

The Delia Smith Dauphinoise Potatoes Recipe is a timeless French classic featuring thinly sliced potatoes baked slowly in a rich, creamy garlic-infused sauce until irresistibly tender. It’s the sort of elegant side dish that pairs beautifully with roast meats, steaks or festive dinners, adding a touch of indulgence to any meal.

A good dauphinoise should have layers of soft, buttery potatoes surrounded by silky cream beneath a beautifully golden, lightly crisp top. Slowly baking the potatoes allows them to absorb the cream, garlic and seasoning while developing a delicate, melt-in-the-mouth texture. Using a balance of cream and milk creates a luxurious dish that’s rich without feeling overly heavy, making this classic recipe a perfect accompaniment for both everyday meals and special occasions.

How to Make Delia Smith Dauphinoise Potatoes Recipe

Prepare the Cream

Preheat the oven to 160°C (140°C fan). In a saucepan, gently heat the double cream, whole milk, garlic, salt, black pepper and nutmeg until just warm, allowing the flavours to infuse.

Layer the Potatoes

Butter a baking dish, then arrange a layer of thinly sliced potatoes over the base. Pour over a little of the warm cream mixture. Continue layering the potatoes and cream until everything has been used, finishing with a layer of cream.

Add the Butter

Dot the top with small pieces of butter to help create a rich, golden crust during baking.

Bake the Dauphinoise

Cover the dish with foil and bake for 1 hour. Remove the foil and continue baking for another 30 minutes until the top is golden brown and the potatoes are completely tender.

Check for Doneness

Insert a knife into the centre of the dish. It should slide through the potatoes easily with no resistance.

Rest Before Serving

Leave the dauphinoise to rest for 10 minutes before serving so the layers can settle.

Serve and Enjoy

Serve warm as a side dish with roast meats, steak or roasted vegetables.

Final Touch

The finished dauphinoise potatoes should have a beautifully golden, lightly crisp top with layers of soft, buttery potatoes beneath, infused with creamy garlic flavour. Rich yet perfectly balanced, this elegant French classic is the ideal accompaniment to both everyday meals and special occasions.

Recipe Tips

• Use a mandoline slicer for uniform potato slices — this ensures even cooking.
• Warm the cream mixture gently to avoid curdling — overheating can cause the cream to separate.
• Layer the potatoes evenly — uneven layers can lead to uneven cooking.
• Rest the dish before serving — this helps the layers set and makes serving easier.
• Avoid overbaking — check from 1 hour 20 minutes to prevent drying out.
• Dotting with butter creates a crispy top — without it, the top may remain pale and soft.
• Use waxy potatoes for the best texture — they hold their shape better than floury varieties.
