Keto friendly roasted leg of lamb

If you know me then you know the only way for me to do lamb is nice and slow on a webber charcoal bbq.

But as I get older and it gets colder out, I am not in as big a hurry to bbq in the winter. When I came across this recipe and had to try it.

This recipe comes from a website called which has, who knew, an keto diet app you can download. I will give it a try over the weekend, and add an update later on the app.

Now I am not giving up the webber, but at -15C, I’d much rather be in the kitchen.

  • 1 lamb leg whole (~ 2 kg / 4.4 lb) – this will yield about 50% cooked meat
  • 1/4 cup balsamic vinegar 60 ml/ 2 fl oz – avoid sweet syrupy types of balsamic
  • 1/4 cup apple cider vinegar or Homemade Fruit Vinegar 60 ml/ 2 fl oz
  • 4 cloves black aged garlic or fresh garlic If you can't find black garlic, use freshly sliced white garlic.
  • 1-2 sprigs fresh rosemary
  • 1/2 tsp sea salt or to taste
  • 2-3 cups water
  • 4 heads small lettuce to serve 400 g/ 14.2 oz

  • Peel the garlic and slice it into smaller pieces.
  • Place the lamb leg into a baking dish. Add balsamic vinegar, fruit vinegar, sliced garlic and rosemary. Season with salt and add water.
  • Cover with a lid and place the lamb in the oven for about 30 minutes per pound. 2 hours for a 4 lb leg.
  • After 2 hours, take the lid off, baste with the vinegar juices, and increase the temperature to 200 °C/ 400 °F (fan assisted), or 220 °C/ 425 °F (conventional). Cook for another 30-45 minutes, basting with the juices once or twice again.
