Made this today. I followed the recipe and found the end result really tasty and satisfying. I wouldn't tweak or substitute anything, I loved it. I did however cook it on high for 4 hours.

Not mad on this. Easy to throw together (I chucked it in the slow cooker the night before, kept it in the fridge overnight and put it on in the morning for about 10 hours), but I wasn't keen on the mustard and porcini mushrooms which gave it a heavy flavour. My husband found it bland. It was ok but I prefer casseroles with a dollop of sweetness from redcurrant jelly etc. If you're a mustard lover then this might be for you! As others have said, it was full of liquid. I put it on the hob (my slow cooker dish is ok for the hob too), added some corn flour and let it thicken up before serving. After 10 hours of cooking the chicken had shredded but was nice enough like that. I leave for work way too early to just cook things for 6 or 7 hours.

Reading reviews that it was watery I went for about 250/300mls water and it still cooked fine. I also blitzed the onion carrot and celery in a mini chopper (I do this anyway because my partner has crohn's) and chucked it in the frying pan after the chicken, which definitely also thickened the sauce. With these tweaks honestly one of the nicest casseroles I've ever made, slow cooker or not. (Although I wasn't using low sodium stock cubes.)

This looked and smelled awful all day but was pleasantly surprising to eat! I had to thicken up the vast amount of liquid with some cornflour but that wasn't a dealbreaker. To be fair I put everything in at the same time and didn't pre-cook anything and it was still really good.

I prepped this on a sun eve to cook on a Monday whilst I was at work. Turned out perfect, (season well) no treaks needed. Don't forget some crusty bread to mop it all up!

If anyone finds a recipe bland, add a little fish sauce, it gives that savoury boost to most dishes. I use it sparingly as is quite strong but really makes a meal.

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.

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.
