Leek & Potato Gratin

We adore a classic potato dauphinois, there’s no better side on a cold, winters day. This twist with lovely leeks is so delicious! We all know that leeks and potatoes are made for each other, and this dish proves it once again. Use your favourite milk or cream, (we used oat cream here) but not too much or you’ll end up making soup. Here is a guide, but this is definitely one of those recipes where you should be flexible and feel your way with amounts. Enjoy!

Ingredients (serves 4)

  • 800g potatoes, very thinly sliced
  • a 250g leek, halved lengthways then rinsed and cut into chunks
  • 500ml milk/cream
  • 1 tsp salt
  • pepper to taste
  • 1/2 tsp ground nutmeg
  • 1 tsp garlic powder (or a crushed clove of garlic)
  • 1 tbsp bouillon powder
  • 1 tbsp Dijon mustard

Method

  1. Turn your oven on to 200C and find a deep baking dish with a lid.
  2. Tumble in your cut potatoes and leek, separate the leek leaves so that they can be evenly distributed through the gratin.
  3. In a measuring jug, whisk together the rest of the ingredients then pour over the vegetables. Mix well to coat each slice in the seasoning then press down into an even layer.
  4. Place the lid on (or use baking parchment/foil/a flat baking sheet if you are using a baking dish without its own lid) and bake until the potatoes are soft. This usually takes around 30 minutes but test with a fork after 20 minutes.
  5. Remove the lid and bake uncovered for 15 more minutes to brown the top (and you can add cheese or breadcrumbs at this stage too if you fancy). Enjoy!
