Gratin Dauphinois

By Groceree

Also known as Potatoes Dauphinoise · Dauphinoise Potatoes

Potatoes sliced thin and baked in cream and milk in a garlic-rubbed dish. No cheese, no stock, no egg — the starch from the potatoes is what thickens it.

Ingredients

  • floury potatoes1.2 kg
  • double cream400 ml
  • milk300 ml
  • garlic cloves2
  • butter30 g
  • nutmeg¼ tsp
  • salt
  • black pepper

Instructions

  1. 01

    Heat the oven to 160°C. Halve one and rub a gratin dish hard all over with the cut sides, then it generously.

  2. 02

    Peel the and slice them 2 to 3 mm thick, on a mandoline if you have one. Do not rinse them — that starch is the thickener.

  3. 03

    Crush the other and bring it to a simmer in a wide pan with the , , , plenty of and .

  4. 04

    Slide the slices in and simmer for 8 minutes, stirring gently, until the liquid has visibly thickened.

  5. 05

    Tip everything into the dish and press the top layer flat so it is submerged.

  6. 06

    Bake for 60 to 70 minutes, until a knife meets no resistance and the top is deep gold.

  7. 07

    Rest for 15 minutes before serving so it sets enough to cut.

Notes

  • No cheese. A true dauphinois has none; adding gruyère makes it a gratin savoyard, which is a different and also good dish.
  • Never rinse the sliced potatoes. The surface starch thickens the cream, and rinsed potatoes give a watery gratin.
  • Simmering the slices in the cream first is what guarantees they cook evenly and the liquid is already thick going in.
