Step-by-step method

  1. 01

    Heat the oven to 180°C. Split leeks and wash between their layers, then slice. Soften in oil for about 8 minutes.

  2. 02

    Slice peeled potatoes evenly, about 3 mm thick. Mix milk, cream, chopped garlic, salt and pepper.

  3. 03

    Layer potatoes and leeks in a shallow baking dish. Pour in the liquid, cover and bake for 30 minutes.

  4. 04

    Uncover, add cheese and bake for about 25–30 more minutes. A knife should pass easily through potatoes in the centre; cook longer if needed, protecting the top.

Cheese colour alone does not show doneness: test potatoes in the centre and allow for dish depth.
