Lactose-free gratin dauphinois


Gratin dauphinois is a great classic of French gastronomy. It can be eaten as a side dish (with grilled meats in summer, for example) or as a main course with a salad. You can also prepare a lactose-free gratin dauphinois !

The secret of the gratin's melt-in-the-mouth texture lies in the reaction that occurs during cooking between the starch in the potatoes and the mixture of cream and milk. The gratin must be melt-in-the-mouth but the potatoes must remain firm. And it works really well with plant-based milk and cream!

How do you make a good lactose-free gratin dauphinois?

Step 1 - Ingredients :

For 4 people:

  • 1 kg firm-fleshed potatoes.
  • 1 clove of garlic.
  • 40 cl oat milk
  • 40 cl cream of oatmeal.
  • Lactose-free margarine.
  • 1/2 nutmeg.
  • Black pepper.
  • Salt.

Stage 2 - preparation :

  • Preheat your oven to 150°c.
  • Peel the potatoes and rinse them in clean water. Cut them into thin slices with a knife or a mandolin. Do not put the potatoes back into the water once they have been sliced.
  • Rub a baking dish with the halved garlic clove and brush the dish with margarine. Lay the potatoes flat in the dish in several layers. 
  • In a bowl, mix the oat milk, oat cream, grated nutmeg, two grindings of black pepper and a pinch of salt.
  • Cover the potatoes with the cream and milk mixture. You should just see small potato wedges sticking out. 
  • Bake in the oven for 2 to 2 1/2 hours. To check the cooking time, plunge a sharp knife into the heart of the gratin, it should sink in without resistance.
  • You can prepare the dish in advance and reheat it for 20 minutes at 150°c before serving.
