Ingredients

For the Dauphinoise Potatoes

1kg floury potatoes, peeled and thinly sliced
2 garlic cloves, crushed
500ml double cream
150ml whole milk
100g Gruyère cheese, grated
1 teaspoon salt
½ teaspoon black pepper
Butter, for greasing the dish

How to Make Mary Berry Dauphinoise Potatoes

Prepare the oven: Preheat the oven to 200°C or 180°C fan. Grease a medium baking dish generously with butter to prevent sticking and help the edges brown nicely.
Warm the cream mixture: Place the cream, milk, crushed garlic, salt, and black pepper into a saucepan. Heat gently until warm but not boiling.
Layer the potatoes: Arrange half of the sliced potatoes in overlapping layers across the base of the prepared dish.
Add cream and cheese: Pour over half of the cream mixture and sprinkle with half of the grated Gruyère cheese.
Repeat the layers: Add the remaining potatoes, then pour over the remaining cream mixture and finish with the rest of the cheese.
Bake covered: Cover loosely with foil and bake for 45 minutes until the potatoes begin to soften.
Finish baking: Remove the foil and continue baking for 20 to 25 minutes until golden brown and bubbling around the edges.
Rest before serving: Leave the dish to stand for 10 minutes before serving. This allows the cream to settle and makes portioning easier.

Tips for the Best Dauphinoise Potatoes

How do I stop the potatoes from being undercooked?

Slice the potatoes thinly and evenly, ideally around 3mm thick. Consistent slices ensure every layer cooks at the same rate.

Can I prepare dauphinoise potatoes in advance?

Yes. Assemble the dish several hours ahead, cover, and refrigerate. Bake when ready to serve.

Why is my sauce separating?

Avoid boiling the cream mixture. Gentle heating helps maintain a smooth and creamy texture throughout baking.

Which potatoes work best?

Floury potatoes such as Maris Piper or King Edward create the softest, creamiest texture.
