A British hot pot is a little like a pie with a scalloped potato topping; this chicken hotpot features a creamy mustard sauce made from a roux using no cream and lots of leeks.

Heat a 30cm or 12" frying pan (nonstick if possible) over a medium-high heat and add the cooking oil. Season the chicken thighs with a little of the salt and then sear on both sides until golden, then remove and set aside. This will take 2-3 minutes on each side.
Whilst the Chicken is cooking, clean the leeks and cut them into 1cm (½") thick coins.
Return the pan to the heat and add the leeks, and soften them for 10 minutes over a medium heat, stirring occasionally, then remove to a bowl.
Return the pan to a medium-low heat and melt 50g (3 Tbsp) of the butter. Add the flour and stir until the mix forms a paste, then add the milk little by little to form a lump-free white sauce.
Remove the sauce from the heat and add the remaining salt, a generous sprinkle of white pepper, the thyme, wholegrain mustard and parsley. Have a taste and adjust the seasoning to your taste.
Cut the chicken thighs into 1cm (½") thick strips and add them to the white sauce with the sauteed leeks and mix it all together, then transfer to a 21cm x 16cm x 4.5cm or 8″ x 6″ x 2″ baking dish (1 Litre).
Cut the potatoes into 5-6mm (¼") thick slices, using a mandolin here really helps, but watch your fingers.
Add a layer of potatoes to the top of the hotpot and dot with the remaining butter, add a pinch of coarse sea salt and place in the oven and cook at 200°C or 400°F for 45 minutes.
If you want a little extra crispiness on the potatoes, slide the hotpot under the grill or broiler for 3-5 minutes at a high temperature.
Allow to sit for 5 minutes. I like to sprinkle with parsley before serving.
