Preparation time

Cooking time

1 hour




  • 1 tbsp vegetable oil
  • 500g/1lb 2oz boneless, skinless chicken thighs, diced
  • 200g/7oz onion, chopped
  • 450ml/ ¾ pint chicken stock
  • 2 tsp wholegrain mustard
  • 1 tsp English mustard
  • 2 tsp runny honey
  • Salt and freshly ground black pepper
  • 200g/7oz parsnips, cut into chunks
  • 250g/9oz carrots, cut into chunks
  • 350g/12oz potatoes, cut into chunks
  • 1 tsp dried thyme
  • 100g/3 ½ oz green cabbage, finely shredded
  • 2 tbsp chopped fresh parsley


National Trust properties grow autumnal root vegetables in abundance, and some, like Attingham Park in Shropshire, even have a Harvest Fair. This simple dinner recipe makes the most of this fantastic British produce.

Preheat the oven to 180°C/350°F/gas mark 4. 

Heat the oil in a large frying pan, add the chicken to the pan, a few pieces at a time, until they are all in the pan, then fry, stirring for 5 minutes over a medium to high heat until evenly browned.

Scoop out of the pan with a draining spoon and add to a casserole dish.

Add the onions to the meat juices in the frying pan and fry gently for 10 minutes until softened and just beginning to turn golden around the edges.

Mix the stock with the mustards, honey and a little salt and pepper. Pour into the frying pan and bring to the boil.

Add the parsnips, carrot and potatoes to the chicken then sprinkle with the thyme. Pour over the onion and stock mix then cover and cook in the oven for 45 minutes or until the vegetables are tender and the chicken is cooked through.

Add the cabbage to a saucepan of boiling water, blanch for 2 minutes then drain well. 

Stir into the casserole, taste and adjust the seasoning if needed then sprinkle with the chopped parsley. Spoon into bowls and serve with warm crusty bread and butter.

Cooking tip

Getting plenty of flavour in the onions in the early stages of cooking will add a lovely sweet flavour to the dish.
