What is Potato Dauphinoise?

It’s a French dish often made up of sliced potatoes baked in milk. Traditionally named ‘Gratin Dauphinois’, this dish has taken on a number of different names and a few different tweaks in ingredients too. Here’s what I like in mine:

Potato Dauphinoise Ingredients

  • Milk
  • Cream
  • Nutmeg
  • Garlic
  • Butter
  • Gruyere (to top)

Yup, pretty simple right? It’s one of those recipes that requires such few ingredients but tastes so incredible.

I feel that a 50/50 ratio of milk and cream gives the perfect amount of richness. I also love grilling some gruyere on top at the very end because, erm, just look at that golden crispy goodness!

Tips for the best Potato Dauphinoise

  • Make sure all over your slices are the same thickness so they cook at an even rate.
  • Work in layers of potato and sauce to ensure a full coverage of cream on the potatoes.
  • Ensure you use double/heavy cream and cook at a low temperature to ensure the cream doesn’t curdle.
  • Let it rest for 5-10mins to give it some final thickening time.
  • Serve with fresh chives, because chives are life.
