Ingredients

  • 4 tbsp rapeseed oil
  • 2 carrots
  • 2 celery
  • 500g/1lb 2oz roasted chicken bones (optional)
  • 1 garlic
  • 100g/3½oz tomatoes
  • 2 sprigs fresh thyme
  • 2 tbsp chopped parsley
  • 3 large onions
  • 2 tbsp chopped fresh coriander
  • 3 large red peppers
  • 6-8 leftover roast potatoes
  • 50g/1¾oz butter
  • salt and freshly ground black pepper
  • 1 tbsp oil
  • 1 garlic
  • 340g/11¾oz Portobello mushrooms
  • 2 tbsp chopped fresh coriander

Instructions

  • For the casserole, preheat the oven to 180C/160C Fan/Gas 5.
  • Heat 1 tablespoon of the oil in a heavy-based casserole over a medium heat. Add the carrots and celery and fry for 4-5 minutes, or until lightly browned.
  • Add the chicken bones (if using; omit if cooking a vegetarian version of this dish) and fry for a further 2-3 minutes, stirring well.
  • Add the garlic bulb, tomatoes, thyme and parsley stalks and stir again.
  • Pour in 1.2 litres/2 pints water and bring the mixture to the boil. Reduce the heat then simmer for 25 minutes. Strain the resulting stock through a fine sieve, collecting the liquid in a clean saucepan. Simmer until its volume has reduced by about one-third. Keep warm.
  • Meanwhile, heat another tablespoon of the oil in a frying pan over a medium heat. Add the onion and fry for 4-5 minutes, or until softened and lightly browned. Stir in the coriander, then season, to taste, with salt and freshly ground black pepper. Remove from the pan and set aside.
  • Add another tablespoon of the oil to the frying pan, then fry the peppers until just softened (about 3-4 minutes). Season, to taste, with salt and freshly ground black pepper.
  • Spoon half of the onion mixture into the bottom of a pie dish. Top with half of the peppers, then cover with a layer of the sliced roast potatoes, keeping the best shaped slices for the top layer.
  • Repeat the layering process with the remaining onions and peppers, then pour enough of the warm stock into the pie dish to just cover the top layer of peppers.
  • Decorate the top of the casserole with a layer of the remaining potato slices. Brush the potato slices all over with a mixture of the melted butter and the remaining tablespoon of oil.
  • Cook the casserole in the oven for 20-30 minutes, or until the potatoes are crisp and golden-brown and the casserole is bubbling.
  • Meanwhile, for the mushrooms, heat the oil and butter in a large frying pan over a medium heat. Add the garlic and fry for 1-2 minutes, or until softened.
  • Add the mushrooms and fry for 2-3 minutes, or until softened and just coloured. Stir in the coriander just before serving.
  • To serve, spoon the red-pepper-and-onion casserole onto serving plates. Serve the garlic-and-coriander mushrooms alongside, with any remaining warm roast potato slices.
