Roast Leg of Lamb


Roast leg of lamb is a comforting, hearty, filling food which is very simple to cook.  In my opinion, the secret to a good Roast leg of lamb is juicy, sweet lamb, which is a little bit crispy on the edges, and thick, rich gravy. It is perfect for a Sunday Roast and as a main course for either dinner parties or family meals.

It is relatively easy to cook and if you are lucky enough to have leftovers you can use it the next day accompanied by a side dish, like Ratatouille. Leftover lamb can be frozen for future use.

1 It is very important not to overcook lamb. The times given in my recipe are for French style (medium) and Greek style (well-done). I would recommend cooking lamb French style and when you cut it decide whether is it cooked enough for you. If yes it is great, if not put it in the oven for further cooking.

2 When making gravy, if stock evaporates too much add a little bit of boiling water, let it soak for a couple of minutes (while you are cutting the lamb) and scrape  the tray with a wooden spoon (spatula)

3 If you are cooking roast vegetables at the same time put them in only for the last 45-55mins of the lamb being in the oven

4 Use a reasonable quality red wine because when you soak the lamb in the wine it gives its flavour to the meat, which can affect the quality of the taste.
