Heat the oven to 160°C.
Heat some oil in a casserole dish, brown the lamb and set aside the lamb to a plate. Sauté the onions and carrots in the pan with a little more oil. Sprinkle over the flour, cook for three minutes, add the worcestershire sauce, pour in the stock then bring to the boil.
Add the lamb and bay leaves, and then turn off the heat. Arrange the sliced potatoes over the meat, and then drizzle with a little more oil. Cover, then place in the oven and bake for 1½hrs until the potatoes are cooked.
Arrange on a plate with the lamb on top of the potatoes and spoon on the stock, vegetables and a sprinkle of chopped parsley.
Freezing and defrosting guidelines
Once the dish has cooled completely, transfer it to an airtight, freezer-safe container, seal and freeze for up to 1-3 months. To serve, defrost thoroughly in the fridge overnight before reheating. Loosely cover with foil and bake until dish is thoroughly heated through. Reheat until piping hot.
