- 3 medium onions, thinly sliced
- 6 large waxy potatoes, peeled and thinly sliced
- 1 bunch thyme, leaves picked
- salt and black pepper
- 1 whole lamb shoulder
- 1 garlic bulb, peeled and separated into cloves
- 568ml/1 pint chicken stock
- cooked French beans (or other green vegetables), to serve
- Preheat the oven to 130C/275F/Gas 1.
- In a bowl combine the onions, potatoes and thyme. Season with salt and pepper.
- Layer the potatoes and onions in a roasting tin and place the lamb on top skin-side up.
- Cut small incisions in the lamb using a small knife and stick the whole garlic cloves in the holes, pushing them into the meat to prevent them burning while the meat cooks.
- Pour the chicken stock over and place in the oven for 4-5 hours, or until the potatoes are crisp on top and soft inside.
- When cooked, remove the lamb from the oven, cover with aluminium foil and set aside to rest for 20 minutes.
