Pre-heat your oven to 220C / 200C fan / gas mark 7 / 425F.
Place the olive oil and vegetables in a flameproof, ovenproof pan. (See Note 1.) Fry over a high heat, stirring frequently, until the vegetables are lightly browned – about 4 minutes.
Add the chicken and fry for 1 more minute, stirring frequently.
Meanwhile, make a quick gravy by putting the 2 tablespoons of flour and the crumbled chicken stock cube into a large jug. Add a splash of cold water and stir to make a smooth paste. Then add the boiling water slowly, stirring to ensure there are no lumps.
Pour the gravy into the pan with the vegetables and chicken. Stir and bring to the boil.
Put the lid on the pan and put the stew into your preheated oven. Cook for 30 minutes or until the vegetables are tender.
Serve with mashed potatoes, baked potatoes and/or green vegetables.
Notes
I use a Le Creuset-style cast iron casserole dish, (AKA dutch oven) which can go on the hob and in the oven. If you don’t have a pan that can go on the hob and in the oven, simply start this stew in a regular saucepan and then tip it into an ovenproof dish to go into the oven.
I use a 4 litres capacity / 24cm diameter dutch oven. (4.25 quarts / 9.5 inches) There is certainly some flexibility with this stew, however, so a slightly smaller or larger dutch oven / saucepan / ovenproof dish would still work just fine.
