Chicken hotpot with leeks in a creamy whole-grain mustard sauce made from a roux without cream and topped with a layer of crispy potatoes.
Cooking this dish takes around an hour and a half, but you can do all of the preparation in advance and throw it in the oven to cook when you are ready.

Potato Topped Creamy Chicken and Leek "Pie"
Us Brits definitely have a thing for a savoury "pie", and they are not all wrapped in pastry!
We, of course, have a rich vein of mashed-topped pies like shepherd's pie and cottage pie. Then, unusual derivations like my sausage and mash pie and fish finger pie, you seriously need to try these!
Then we have a hotpot, in the UK this means a pie or stew topped with a scalloped potato lid.
The most famous of these is arguably the Lancashire hotpot, a wonderful lamb dish that I adore!
This creamy chicken and leek hotpot joins other similar ideas like my sausage hotpot, vegan mushroom hotpot, minced beef hotpot, spicy minced lamb hotpot, and a spicy beef hotpot. The panacalty is a dish from the North East of England, and in many ways it is so similar to a hotpot as to make no difference
Whilst being creamy, this hotpot uses no cream, and the base of the sauce is a roux, a deliciously creamy white sauce made from butter, flour and milk, very much like my chicken gratin recipe.
The filling gets flavoured by thyme and a little wholegrain mustard before being chucked in the oven until baked to perfection.

Frequently Asked Questions
Do I have to use a mandolin?
No, you can slice the potatoes by hand. Just take care to cut them evenly because they can cook unevenly if you don't!
Do I have to use wholegrain mustard?
No, not at all, use any mustard that you have at home; however, wholegrain mustard tends to be on the mild side, so you may want to reduce the quantity if you are using something more "pokey".
Can I prepare this in advance?
Kind of yes. You can put together the filling for the hotpot up to 24 hours in advance, but I would not slice the potatoes until you are ready to cook.
Alternatively, you can bake this to completion and then cool and cover it with foil; it will last in the fridge for 2-3 days. To reheat, just slide it into a low-medium oven (150°C or 300°F) until piping hot.
Can I use sweet potatoes to top this dish?
I got asked this question on social media and had to try it out. It was not to my taste personally because the creamy filling and sweet potato did not complement each other too well.

Serving Suggestions
This hearty, creamy chicken hotpot has most of what you need to fill yer belly, and as a result, the only thing you need to add is some greens.
The pictures here show it served with roasted tenderstem broccoli. Anything roasted in the oven is perfect because it is already hot, so why not use it?
Sticking with the same theme, you could throw some roasted savoy cabbage on the side or even roasted miso Brussels sprouts.
I you are not leveraging the oven, consider dishes like buttered cabbage, green beans amandine or some Air Fryer asparagus.

Creamy Chicken and Leek Hotpot Recipe
Ingredients
- 350 g Skinless and Boneless Chicken Thighs 12oz
- 1 tablespoon Cooking Oil
- 350 g Leeks 3 Cups (prepared volume)
- 75 g Butter 3 tablespoon
- 50 g Flour ¼ Cup + 1 tablespoon
- 500-550 ml Milk 2-2¼ Cups
- ¾ teaspoon Salt
- 1 Pinch White Pepper
- 2 tablespoon Wholegrain Mustard
- 1 tablespoon Fresh Thyme Leaves
- 10 g Fresh Parsley ⅔ Cup
- 500 g Potatoes 3-4 medium
Instructions
- 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.

- Allow to sit for 5 minutes. I like to sprinkle with parsley before serving.

Hi Lori... yes, this is not one that will make your average "dietitian" smile with glee.
I create balance in my diet by eating and cooking lots of lower fat/lower calorie dishes, but on occasion, a bit of a blow out is more than welcome.
Enjoy Brian

Hi Lesley...
Technically you could freeze this and it will be fine, however it will not be at its best and would be a little drier than I would like it to be.
You could add a splash of chicken stock when you are reheating the dish, to help it out a little.
Enjoy Brian :)

This is absolutely delicious and easy to make. I made it for a group of 44-46 people…..yes I know I am bonkers for volunteering but the feedback I got made it all worthwhile. Clean plates, seconds served and not one adverse comment. But a few points to note… this recipe states for two people who must have big empty bellies 🤣. It easily does Four people, especially as the usual amoun5 of uncooked chicken per person is around 125g So I just upscaled the recipe 11 times for 44 people and there was plenty for seconds as well I also mad3 the sauce using cornflour 30g per 500ml milk to avoid messing around with making a roux. Much easier. Just mis all the seasonings etc in the milk and warm up milk, add butter then add cornflour mixed in a some of milk (cold) then add slowly to warm milk and bring to a simmer stirring well. It’s so much easier but you must use less cornflour than plain flour. I also recommend reducing the amount of salt to half teaspoon table salt per 500ml as I prefer to use sea or rock salt for seasoning chicken. It’s also possible you forget to use all the salt in this recipe for the sauce instead of using some of it for seasoning the chicken! So thank you for this recipe… it will become a regular in our house. Cheers
