A recipe for slow-roasted shoulder of lamb with harissa & garlic

Slow roasting a shoulder of lamb with harissa and garlic is one of those incredibly easy and hands-off recipes where the oven does all the work. The lamb roasts slowly for four hours until it falls off the bone. The strained pan juices make a delicious jus to pour over the shredded meat.

This lamb with Middle Eastern flavours is the perfect centrepiece for a feast. I like to serve it with a few sides and tzatziki along with pita bread so people can build their own pockets. Family-style eating like this is the best way. 

Slow-roasted shoulder of lamb with harissa, garlic & rosemary recipe

For years I have been stuck making slow roasted shoulder of lamb with garlic and rosemary and it’s really a great recipe. However adding harissa, thyme, smoked paprika and stock to the pan along with some cut-up root red onions and garlic heads makes a delicious sauce that keeps the meat succulent. This is my new favourite roast shoulder of lamb recipe and I can’t wait to make it again.

I prefer to cook lamb shoulder on the bone. This is where all the flavour lies. You can use a deboned shoulder if you prefer but you may need to adjust the cooking time slightly.

How to make slow-roasted shoulder of lamb

I cook the lamb completely covered for a full four hours. There is no need to even check it. If you feel it needs any additional browning after this time, simply put it back into the oven uncovered for 5 – 10 minutes. I find to browns enough with this method and if your oven is hot enough.

While the lamb rests, strain the pan juices and vegetables through a fine sieve and then strain out the fat. I have included my foolproof and preferred method to skim lamb fat off roasting liquid. See below.

I developed this recipe for Backsberg Pumphouse Shiraz, a full-bodied wine aged for 12 months in predominantly French oak with 10% American oak driving the vanilla and coconut notes. This wine needed a flavour-packed and rich meat dish to pair with it.

TASTING NOTE: On the nose expect old spice, cedar and vanilla. Exhibiting a wonderful velvety depth, this is a powerhouse of a wine with flavours of ripeplum, black cherry, mulberry, liquorice and spiced fruit cake. A generous wine that just keeps giving. Pair with hearty stews and rich roasts.

What to serve with the slow-roasted shoulder of lamb?

I love to serve this with a herby cous cous salad with mint, olives and parsley. You can add any other roasted vegetables to the cous cous such as aubergine, zucchini, red onion and peppers.

Griddle-fried halves of zucchini are my favourite way to prepare this vegetable. I can honestly eat a whole tray. I season the zucchini halves with a salt mix and olive oil, and fry until golden on each side on a griddle pan. This can be served at room temperature.

Roast potatoes. or roast potato wedges are always a great accompaniment with lamb.

A mixed green salad or my spinach salad with grilled zucchini, peas, feta and mint is perfect here and delivers green vegetables and salad in one. Or a Lebanese fattoush salad would be lovely.

I love to make simple tzatziki with thick Greek yoghurt, mint and lemon, or my quick zucchini tzatziki to serve with this lamb along with homemade or store-bought pita bread.
