Slow roasted garlicky leg of lamb with rosemary potatoes

Slow roasted garlicky lamb

 

Lamb is one of our favourite Sunday lunches.  I think with lamb chops, they’re nice when they’re tender and pink in the middle.  With a leg of lamb, though, especially at this time of year, we all prefer it slowly cooked and really falling off the bone.  I serve mine with rosemary potatoes and some of my apple and mint chutney. Delicious.

Slow roasted garlicky leg of lamb

1 leg of lamb (or a half leg, to be honest – works just as well)

Rapeseed oil

2 or 3 cloves of garlic

Preheat the oven to 160 (170)/gas 3.

In a pestle and mortar, bash up the garlic with a generous pinch of salt and pepper until it forms a paste, then add about a tablespoon of rapeseed oil.  Smoosh this paste all over the lamb.

Pop the lamb into a roasting tin and put it in the oven.   In his 2005 recipe for slow roast lamb with chickpea mash,  Nigel Slater recommends adding about 250ml of water after about half an hour, which works really well and helps to make a lovely gravy at the end of it.  I cover it for the first few hours with some foil, too.

Then, just leave the lamb alone for a good five hours.  If you want to leave it longer, turn the heat down a little.  It won’t spoil.

For the rosemary potatoes

Floury potatoes

Sprig or two of rosemary

Peel enough largish potatoes to feed your crowd.  Cut into quarters and bring to the boil in some salted water. Simmer until tender, then drain and set aside.

When the lamb has about 15 minutes to go, drain off all the liquid into a jug.  Skim off all the fat and pour it into a roasting tin (reserve the rest for the gravy).  You really don’t need THAT much, as the potatoes just need to be tossed in it, not drowning in it, but by all means add a bit of extra oil if you want to.

Whack the heat up to gas 7/220 degrees (the lamb will be fine in there just as the oven is heating up) and put the roasting tin into the oven.  After the five hours, take the lamb out, cover with foil and maybe a tea towel and leave it to rest.  Add the potatoes and a tablespoon or so of chopped rosemary to the hot oil.  Remember to wiggle them about occasionally – they’ll take 30 to 40 mins to crisp up.

For the gravy

2 tbsp plain flour

About 250ml lamb or chicken stock

To make the gravy, pour a couple of tablespoons of the leftover meat juices into a saucepan (there’ll still be some fatty stuff in there).  Add a tablespoon or two of plain flour and mix well.  Cook this pasty stuff for a couple of minutes, then start to add the rest of the juices, whisking them in slowly, then you can add in the stock.  Bubble away so it thickens slightly.

And there you have it.  Delicious, falling apart meat, crispy potatoes and yummy gravy.  Happy Sunday.

… and just to prove that it works just as well with a half leg of lamb…

    Just had for early family xmas meal – went down a treat, but could have done with a little more cooking – this may be down to my oven regulator.

    Hi, sounds lovely but I`m slightly confused with timings – you said at beginning of recipe “leave the lamb alone for a good five hours” but then when talking about the roast potatoes you said “At the four hour mark, take the lamb out” ?? help or am I being a bit doh ?!!

      Hi Jan. No, you’re right, that’s my fault. The original recipe was for four hours, which works absolutely fine, but I just found it was even better when left for five so I changed it, but forgot to change that bit! I’ve amended, thanks xx
