  • 250g mushrooms, quartered
  • 15g dried porcini mushroom, soaked in 50ml boiling water
  • 500ml stock made with 2 very low salt chicken stock cubes (we used Kallo)
  • 2 tsp Dijon mustard, plus extra to serve
  • 2 bay leaves


  1. Heat the butter and oil in a large frying pan, cook the onion for 8-10 mins until softened and starting to caramelise. Meanwhile put the flour and a little salt and pepper in a bowl and toss the chicken in it. Add the garlic and chicken to the pan and cook for 4-5 mins more until the chicken is starting to brown.

  2. Transfer to your slow cooker, along with the rest of the ingredients, including the soaking water from the porcini mushrooms. Give it a good stir. Cook on Low for 7 hours or High for 4 hours. Remove the bay leaves and serve with Dijon mustard on the side.

I made it to the recipe except that I used whole grain mustard - because that's what I had. We thought it was delicious. I loved the intensity of flavour that the porcini mushrooms gave. A very important element of the dish. I'm going to make it again for someone who doesn't like mushrooms. I plan to substitute with bell peppers and will add some anchovies to replace the flavour of the porcini mushrooms.

I happened to have this on the go the day it snowed and it was very welcoming! I followed recipe to the letter and it was delicious, I did 7 hours on low and the kids loved it. We agreed we'd like cabbage with it next time.

Lovely. Followed the recipe exactly and it turned out beautifully. Everything was cooked perfectly (I cooked in slow cooker on low for 7+hrs). The kids gobbled it up and both my husband and myself thought it was tasty and satisfying. It was very straightforward to make so it'll be going into the autumn/winter repertoire.

A huge hit in this house, my two year old, four year old and husband all loved it. It's going to be a regular meal here!

I didn't stick completely to the recipe. Didn't have celery or porcini mushrooms so I used an onion and porcini paste. I was worried because the Dijon tasting too strong but by the end it didn't at all. My husband isn't a chicken fan but lived it. Made dumplings with it which went down a treat too!

I followed the recipe exactly except swapped dijon mustard for whole grain - thought it was delicious. It was quite running though - we ate it in bowls instead of plates but none the less very tasty - juice left over made a delicious soup the next day! Will definitely do again.

This is a really warming and tasty casserole which I'd definitely cook again. Had all intention of doing in the slow cooker but didn't have time before work so put it in my pressure cooker, worked a treat too! I did add some dried thyme as noticed a few bland comments.

I would highly recommend this recipe, it was absolutely delicious. I will definitely cook it again with maybe an addition of some white wine.

Can you freeze the leftovers? If so, what’s the best way to reheat?

Thanks for your question. Yes you can! We'd suggest defrosting in the fridge overnight and then reheating in a saucepan on the hob.
