240 calories/serving


900 g lamb's leg
2 cloves garlic
1 tbsp olive oil 15 mL

1 onions, coarsely chopped 200 g
2 sprigs rosemary, fresh 10 g
1/2 cup red wine 125 mL

Before you start

You should estimate 3 ½ h per kilo of meat.

A baking dish or casserole with a tight-fitting lid is necessary for this recipe.


  1. Preheat the oven to 140°C/275°F.
  2. Peel the garlic cloves and slice them in half lengthwise. Cut small slits in the surface of the lamb with a sharp knife and put a piece of garlic into each slit.
  3. Heat the oil in a casserole or roasting pan over medium heat. Brown the lamb thoroughly on each side until golden, about 7-8 min. Add salt and pepper, then remove the lamb from the pan and set aside.
  4. Coarsely chop the onion and sauté in the same pan, 4-5 min until translucent and soft. Put the lamb back into the pan, add the rosemary sprigs and wine. Cover and cook in the middle of the oven. Calculate 3 ½ h per kilo of meat. When ready, the meat will fall apart when inserting a fork.
  5. Serve.

You were correct about this recipe - it does fall off the bone. Of the 8 people for Easter dinner, 2 loved it, 2 liked it and would have it again and 4 of us found it to be overcooked. The next day, I cooked a smaller lamb the traditional way (open pan with wine and vegetables) until cooked medium (some parts medium rare) and the 4 of us were in heaven. The suggested carrot and leek side dish was fantastic.
