  • 500ml chicken stock
  • 4 tbsp vegetable gravy granules


  1. Put the veg and chicken in a slow cooker. Pour the stock over and around the chicken thighs, then mix in the gravy granules to thicken it up (the sauce will be quite thick – use less gravy if you prefer a runnier casserole).

  2. Switch the slow cooker to low and leave to cook for at least 4 hrs, or up to 8 hrs – try putting it on before you go to work, so that it’s ready when you get home. Season well, then serve.

Really enjoyed this! I had veg stock and chicken gravy granules in so used them and added a bit of salt and rosemary. Love how easy it is!

Meh - needs tweaking. Very bland in flavour and gravy too watery. Will try making up gravy granules and then adding the stock cube to that. Needs garlic and herbs. Will try adding mushrooms and possibly bacon next time for flavour. It's fine and may suit kids as is, but the whole point of slow cooking is that there's loads of time for the flavours to develop and this recipe really misses that point!

Could this instead be cooked in the oven, in a casserole dish, if you needed it faster? Btw I like the gravy thick. I tried this in the slow cooker and it was delicious, but I'm concerned the gravy will dry out in the oven

This was actually really tasty; much tastier than I expected. I added a lot more carrots and also an onion as I didn't have a leek. I added peppers too for some extra vegetables. There was lots of broth left so you could always have some bread to soak up the juices too.

Perfect for making in batches as it is so easy and tastes even better after freezing and re-heating.

This was really easy to prep with no browning before putting in the slow cooker. I didn’t bother chopping up the chicken thighs as by the time we ate, the meat was falling apart anyway. The gravy granules are an essential as without it, the dish would be more soupy.
