Creamy, Garlicky, Crispy & Extremely Delicious Potato Dauphinoise. The Perfect Side Dish.

Potato dauphinoise is seriously one of the best comfort dishes in the world. This recipe is slightly different from what you might usually see from other recipes, and in my opinion, this technique trumps other methods. 

In this one, we create an infusion by heating cream, garlic and thyme together, which creates incredible flavour and aroma and helps reduce cooking times. This potato dauphinoise recipe is ready to be paired with all your favourite proteins or served as a table filler. Please enjoy.

Ingredients

  • 1.2 kg All-Rounder Potatoes
  • 600 ml Thickened Cream
  • 35 g Unsalted Butter Cubed
  • 3 Garlic Cloves Minced
  • 5 g Fresh Thyme Picked & Chopped
  • 260 g Mozzarella Cheese Grated
  • 100 g Gruyère Cheese Grated
  • Salt & Pepper To Taste

Method

  • Preheat oven to 180°C (350°F).
  • In a bowl, combine the grated mozzarella and gruyere to make the cheese mix. Set aside.
  • In a saucepan, add the thickened cream, unsalted butter, minced garlic, thyme and seasoning to taste. Place over medium-high heat, stir to combine, and heat until just hot. Don't allow it to simmer or boil.
  • Neatly lay ⅓ of the sliced potatoes into a 26cm x 18cm baking dish, completely covering the bottom. Pour over ⅓ (200ml) of the cream mix and season to taste. Repeat 2 more times to create 3 layers of potatoes and cream, using all of the cream mix. Don't add any cheese at this stage — it all goes on top.
  • Place a sheet of parchment paper over the top and cover the baking dish with aluminium foil. Bake in the preheated oven for 1 hour. Carefully remove the foil and parchment, cover the top with the full cheese mix, and bake for a further 20-25 minutes or until golden brown and a crust has formed. Remove and let cool for 15-20 minutes (this makes it easier to slice).
  • Slice the dauphinoise into 6-8 portions, carefully scoop out, and serve as a side with your favourite proteins or salads. Dig in.
Chef's Tips
Slice the potatoes as evenly as possible — a mandoline is worth using here, since uneven thickness means some slices are undercooked while others turn to mush.
Don't let the cream mixture come to a simmer or boil before pouring — overheating it before baking can cause the sauce to split in the oven.
Let the dauphinoise rest for the full 15-20 minutes before slicing — it's still setting when it comes out of the oven, and cutting too early will make it fall apart instead of holding neat layers.
Storage & Reheating
Will keep in the fridge for up to 3-4 days in an airtight container. Reheat individual portions in a covered dish in the oven at 160°C (320°F) until warmed through, or in the microwave for a quicker option (texture will be softer). Not recommended for freezing — the cream sauce will split and turn grainy once thawed, and the potatoes lose their texture.

What's The Difference Between Potato Dauphinoise & Potatoes Au Gratin?

Potato dauphinoise and potatoes au gratin are very similar in the way they are made, but there’s a very small change that separates the two. 

Potato dauphinoise is made with uncooked, thinly sliced potatoes cooked in a cream sauce, whereas potato au gratin is made with pre-cooked, thinly sliced potatoes in a cream sauce. The only real difference is one is pre-cooked, and the other isn’t.

    Hi there,

    Love your potato dauphinoise recipe.
    If I make the night before, is it best to add the final layer of cheese when you reheat?

    Thanks

    Jenny
