Ingredients

  • 1 kg Potatoes (such as Maris Piper) Peeled and very thinly sliced
  • 1 Onion Peeled and very thinly sliced
  • 250 ml Vegetable stock
  • 5 g Fresh thyme (1 tbsp) Leaves only
  • 50 g Butter
  • Salt and freshly ground black pepper

Instructions

  • ‌Preheat your oven to 180℃ fan/200℃/Gas Mark 6/400F.
  • Grease a 20 x 20 cm oven proof dish using some butter.
  • Spread a thin layer of onions in the bottom of the dish, then cover with some potatoes, a sprinkling of fresh thyme, salt and pepper and several small knobs of butter.
  • Continue layering as above until the dish is full, making sure you end on a potato layer.
  • Carefully pour the stock into the dish, add the final knobs of butter and a good seasoning of salt and pepper.
  • Place the dish on to a baking sheet, cover with foil and bake for 30 minutes, then remove the foil and cook for a further 20-30 minutes until the potatoes are cooked through and the top is golden and crispy.

Notes

Potatoes: US potatoes that can be used as substitutes for Maris Piper are Burbank russet or Desirée. 
Butter: You should use a half stick of butter if you're in the US. 
Slicing: It’s important to slice the potatoes very thinly for this recipe. I used this handy chopping device for the job, which saved time.
Herbs: If you can, use fresh herbs here as they will give a much better flavour. Dried herbs tend to work better when cooked in a larger volume of liquid. If you do need to use dried herbs, halve the amount in the recipe.
