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.
