A proper low-and-slow project: a whole lamb leg seared hard, then braised for hours with balsamic, a whole garlic bulb and thyme until it falls apart at the touch of a fork.
The braising liquid reduces down into a rich, dark sauce while the lamb rests, and gets spooned generously over shredded lamb and buttery ricer mash. Fresh chives and parsley on top keep it tasting bright rather than heavy.
It's built for meal prep — shred, portion, and freeze what you don't eat straight away.
1 lamb leg, bone-in (plus any smaller trim pieces)
2 tbsp olive oil, for searing
Salt and black pepper
1 brown onion, halved
1-2 carrots, quartered
1 whole garlic bulb, halved crosswise (skin on)
3 sprigs fresh thyme
3 tbsp balsamic vinegar
Stock, enough to come 1/3-1/2 way up the lamb
Water, to top up if needed
1 tbsp cornflour (optional, for thickening sauce)
Mash
1.5kg potatoes, peeled and quartered
Salt, for the potato water
80g butter, softened
150ml warm milk or cream
Salt and black pepper, to taste
To Serve
2 tbsp fresh chives, finely chopped
2 tbsp fresh parsley, finely chopped
Method
Sear the lamb:
Pat the lamb leg (and trim piece) dry, then rub all over with olive oil, salt and pepper.
Sear in a large stock pot over medium-high heat on all sides until well browned.
Remove and set aside.
Caramelise the aromatics:
Reduce heat to medium. Add the onion, carrots and garlic bulb (cut-side down) and cook a few minutes until lightly caramelised.
Deglaze:
Pour in the balsamic vinegar, scraping up the browned bits from the bottom of the pot.
Build the braise:
Return the lamb leg and trim piece to the pot, tucked in beside or under the main leg.
Add the thyme, then pour in stock (topping up with water if needed) so the liquid comes about 1/3 to 1/2 way up the lamb — don't fully submerge it.
Braise low and slow:
Bring to a gentle simmer, cover, and reduce to low.
Braise for around 4 hours, turning the lamb partway through so all sides get a mix of braising liquid and steam contact.
Check the smaller trim piece partway through and remove it early if it turns tender before the main leg.
Rest:
The lamb is done when it easily pulls apart with a fork.
Lift it onto a platter, tent loosely with foil, and rest while you finish the sauce and mash.
Make the sauce:
Strain the braising liquid into a saucepan, discarding the vegetables and garlic skins (or squeeze the roasted garlic cloves into the sauce for extra flavour).
Simmer to reduce slightly.
If serving fresh, mix the cornflour with 1 tbsp cold water and stir into the simmering sauce, cooking 1-2 minutes until thickened.
If freezing a portion, leave that portion unthickened as a plain jus and thicken it fresh when reheating.
Make the mash:
Boil the potatoes in salted water until a knife slides in with no resistance, about 15-20 minutes.
Drain well and let steam off for a minute or two.
While still hot, pass through a ricer back into the empty pot, then fold in the softened butter until melted through.
Gradually fold in the warm milk or cream until you reach the consistency you want — avoid vigorous beating.
Season with salt and pepper.
Shred and serve:
Shred the rested lamb off the bone, discarding excess fat, gristle and bone.
Serve the mash topped with shredded lamb, spoon the sauce over, and finish with a scatter of fresh chives and parsley on top rather than mixed through, to keep them tasting fresh.
Meal prep:
Portion shredded lamb into containers, spooning a little reserved braising liquid over each to keep it moist.
Keeps in the fridge for 3-4 days or the freezer for up to 3 months.
Key Nutrients & Benefits
Lamb leg is rich in high-quality protein, iron, zinc and B12, and the long braise breaks down connective tissue for a tender, fall-apart texture without needing added fat. Garlic and thyme bring antioxidants, and potatoes add potassium and a good dose of energising carbs.
