1. Preheat the oven to 325°F (160°C). Beginning and ending with potatoes, layer the lamb, onions, and carrots in a large, heavy casserole, seasoning each layer with salt and pepper. Tuck in the thyme and bay leaf. Add the stock and cover.

2. Bake for 1 hour. Uncover and bake 30–40 minutes more, until the potatoes are browned and the meat is very tender. Serve hot.
