Asked on 7 Dec 2022 by Eleanor Shutie

Hi
I am making gratin Dauphinoise potatoes for 16 people. Can I make this the night before? It is for lunch. Do I need to quadruple the recipe and if using two large dishes how Long should I cook it for? What size dishes do you recommend? Can you advise please? Many thanks Eleanor

Hello Eleanor, 

Yes do 4 times the recipe.

About 28cm oval dishes. 

I think it may need 10 – 15 extra minutes in the oven.

I would not make it the day before but to get ahead I would…

  • Peel, slice and rinse the potatoes and then keep them submerged in water in a lidded container in the fridge.
  • Crush the garlic and mix with the milk, cream and seasoning and keep in a lidded container in the fridge.
  • Butter the dish and cover it and leave in a cool place.

Then on the day, give the cream mixture a good stir and then drain, dry and layer up the potatoes with the cream in the dish, and bake, perhaps as I said allowing an extra 10 – 15 minutes.

Kind regards

Lindsey
