The roast that cannot be overcooked — give it half a day and it gives up entirely
Most roast anxiety comes from a five-minute window: pull it too early, it's raw; too late, it's leather. This method deletes the window. You give the lamb a hard blast of colour, then drop the oven right down and walk away for the better part of an afternoon. Somewhere in hour three the meat stops resisting altogether — a spoon will do the carving. There's no thermometer stress, no window to miss, and the pan underneath quietly builds the best juices you'll pour all winter. Patience, rewarded.
Ingredients
- 1 Your Farmer grass-fed lamb roast (approx 1.5kg, leg or shoulder)
- 2 tbsp olive oil
- Salt and pepper to season
- 1 brown onion, thickly sliced
- 4 cloves garlic, smashed
- 2 sprigs rosemary
- 300ml chicken or beef stock
- 1 tsp red wine vinegar, to finish the juices
Instructions
Heat the oven to 220°C (200°C fan-forced). Lay the onion, garlic and rosemary over the base of a snug roasting dish or casserole — they'll hold the lamb off the base and flavour the juices.
1 onion4 cloves garlic2 sprigs rosemaryPat the lamb dry, rub it with the oil, season generously and sit it on the trivet.
1 lamb roast2 tbsp olive oilRoast uncovered for 20 minutes, until the surface is taking on real colour.
Pour the stock around the lamb, cover the dish tightly — a lid or a double layer of foil, sealed at the edges — and drop the oven to 150°C. Leave it alone for 3½ hours.
300ml stockUncover and roast a final 30 minutes to burnish the surface. The meat is ready when it gives way to a spoon with no argument — this is deliberately cooked well past pink, into pull-apart territory.
Rest the lamb, loosely covered, for 20 minutes. Meanwhile, skim the fat from the pan juices, mash the soft onions in (or strain them out for a clearer jug), add the vinegar and season to taste.
1 tsp red wine vinegarPull the lamb into thick pieces — no carving knife required — and serve it drenched in the pan juices, with mash or roast spuds to catch what escapes.

Why Low and Slow Cannot Miss
A quick roast and a slow roast are two different bets on the same cut. The quick version chases a five-degree window around medium; this one drives straight past that window and keeps going, until the connective tissue that would make overcooked lamb tough has melted into gelatine instead. That's why it's nearly impossible to get wrong — once the collagen has surrendered, an extra half hour just makes it more tender. Shoulder is the natural fit, marbled and built for the long haul, but the covered dish and the stock mean a leg from a Your Farmer® share lands just as soft. It's the difference between fighting a cut's nature and working with it — the same thinking behind how we farm, honestly.
Swaps and Variations
Swap the stock for dry white wine and the juices turn French. Go lemon juice, dried oregano and extra garlic and you're most of the way to a Greek island. A tablespoon of harissa or a dry spice rub worked on before the first blast takes it somewhere warmer again. Serve it over mash, soft polenta, or stuffed into flatbreads with yoghurt. Beef responds to the same patience — topside in a low oven is that story on the other animal. The roast itself arrives in Share A of the pastured lamb share, from lambs that only ever ate grass.
Storage and Leftovers
This is the best make-ahead roast there is. Cook it entirely, store the pulled meat in its juices, and it keeps 3–4 days in the fridge or 3 months in the freezer — then reheats, covered, at 160°C without any loss of dignity. Day-two lamb, shredded and warmed through those juices with a tin of tomatoes, becomes a ragu for pappardelle that tastes like it took the weekend. It sort of did.

Sirloin with Green Peppercorn Sauce
The steak-restaurant order you can make in one pan
There's a reason the green peppercorn sauce has never left the steak-restaurant menu: it's magnificent, and it takes about ten minutes. The little peppercorns come in a jar of brine, sitting near the capers at the supermarket, and they bring a gentle heat that cream rounds off beautifully. You'll sear the sirloin in a heavy pan, rest it, and build the whole sauce on the browned bits left behind. Two steaks, one pan, and a dinner that feels like a night out.
Warm Eye Fillet and Roast Pumpkin Salad
Two small steaks, three full plates
Here's a quiet bit of kitchen maths. Two 140g medallions doesn't sound like dinner for three — until you roast a tray of pumpkin, sear the fillet medium-rare, rest it properly and slice it thin across the grain. Suddenly every plate gets sweet golden pumpkin, creamy feta, toasted pepitas and a generous fan of the tenderest beef there is. It's the kind of dinner that feels abundant without being heavy, and it makes the smallest pack in the share go further than you'd believe.
Sirloin with Bordelaise-Style Red Wine and Shallot Sauce
Occasion cooking from a bottle of red and a bit of patience
This is occasion cooking, but be clear about what that means: the sauce is red wine, eschalots and stock reduced patiently in a small saucepan, finished with cold butter until it turns glossy. Half an hour, most of it unattended. Meanwhile the sirloin gets a proper sear and a proper rest, and the two meet on a warm plate over mash. It's the kind of dinner restaurants charge dearly for, made from one steak and the open half of a bottle you were drinking anyway.
