Potatoes cooked in stock with lamb fat drippings are mouth-watering. Once the potatoes caramelise and are served with succulent soft lamb and delicious gravy it makes this a recipe not to be missed. Allow it to slow cook, it will be worth the wait.

Kitchen Tip!  Use left over lamb in wraps, with tzatziki, lettuce and fresh mint.

25 mins
4 hours
Serves: 6 portions
2.2kg whole leg of lamb
4 garlic cloves, halved
1tsp each paprika, dried thyme, coarse black pepper, salt
2 large onions, quartered
1kg waxy potatoes, sliced into 3 cm thick slices
Fresh rosemary or thyme stalks
650ml hot beef or lamb stock
3tbls lamb fat (from the lamb)
40g Bisto powder
100ml red wine
1 – 2 tsp redcurrant jelly
1tsp Worcestershire sauce
1tsp Dijon mustard


1              Preheat the oven to 220’C

2              Put the lamb on a board and make a few slits in the skin at random spaces, insert the garlic into the holes. Put into a roasting pan and put into the hot oven and roast for 20 minutes on each side until browned. Take it out the oven and set aside.

3              In a larger, deep roasting pan, add the onions and potatoes and mix together. Season with salt, pepper and fresh herb stalks. Add hot stock to the tin.  Place the lamb with the smooth side up – on top of the potatoes. Cover tightly with foil.

4              Reduce the temperature of the oven to 160’Cand cook for 3 ½ – 4 hours, or until the lamb is completely tender. Remove the lamb from the pan and put it onto a board. Strain excess fat from the pan into a bowl. Set aside.

4              Increase the oven temperature to 220C .  Put 2 knobs of butter over the potatoes and onions and put the pan back into the oven to brown the potatoes for 20 to 25 minutes.

5              Gravy:  Spoon 3 TBLS of the set aside fat, into a saucepan and heat. Add the red wine, Bisto powder and stock and whisk well. Bring to the boil, and then reduce to a simmer. Add the redcurrant jelly, Worcestershire sauce and mustard. Whisk until smooth and thickened.

6              Carve the lamb and serve with gravy and potatoes and onion.  A mixture of steamed green vegetables can be served on the side.
