Potatoes Dauphinoise

Last Updated on 11/01/2022 by richard

Potatoes Dauphinoise or gratin dauphinois is a French dish of sliced potatoes baked in milk or cream, using the gratin technique.


It originates from the Dauphiné region in south-eastern France, situated between the Alps and the Rhone valley.


English speaking countries like the USA or here in the UK assume that anything gratin means baked with a layer of cheese on top. In France there is NO cheese in gratin dauphinois. The addition of cheese or eggs would relegate the dish to food for peasants. I must be a peasant, I like cheese.

Additionally, a traditional French gratin dauphinois contains no garlic but does require the baking dish to be rubbed with a clove of garlic to give a subtle hint to the flavouring.

This recipe does have a cheese topping, but at the risk of offending the French, I will take my chances.

  7. Pack the potato slices on their side
  8. Double the cream, use cream and crème fraîche
  9. Nutmeg, a grating adds a touch of sweet spice

  • 500 ml Double cream
  • 500 ml Milk full fat
  • 3 cloves Garlic
  • 8 potatoes large Maris Piper or Desirée
  • 100 g Cheese grated gruyère or cheddar


  • Pre-heat oven to 190°C/170°C fan/gas 5.
  • Tip the double cream, milk and garlic cloves into a large saucepan and bring to a simmer.
  • Slice the large potatoes very finely, about 3-4mm, add them to the cream and simmer for 5 mins or until just cooked.
  • Gently stir to separate the potato and stop it sinking and catching on the bottom of the pan.
  • Remove the potatoes with a slotted spoon and place in a wide shallow ovenproof dish. Season with salt and pepper between each layer until they are about 5cm in depth.
  • Pour over the garlic-infused cream (discarding the garlic) – just enough to seep through the layers and leave a little moisture on the surface.
  • Scatter over the grated cheese, then bake for 30 mins until the potatoes are soft and browned – increasing the heat for the last 10 mins to brown the crust.
