A Note from the Chef
This isn’t a weeknight rush job; it’s a weekend celebration dish. The ancient method of “confit” — slow-cooking in fat — transforms a robust lamb shoulder into something extraordinary: meat that is impossibly tender, richly flavored, and falls apart at the nudge of a fork. We’ve paired it with a bright, sticky glaze of roasted garlic, wholegrain mustard, and honey to cut through the richness. The result is dramatic, deeply satisfying, and well worth the wait.
Ingredients
For the Lamb & Confit:
1 whole bone-in lamb shoulder (approx. 2-2.5 kg / 4.5-5.5 lbs)
4-5 large sprigs of fresh rosemary
6-8 sprigs of fresh thyme
1.5 kg (3.3 lbs) duck fat, goose fat, or a high-quality olive oil (enough to submerge)
1 whole head of garlic, halved horizontally
2 large brown onions, roughly chopped
2 large carrots, roughly chopped
3 bay leaves
1 tbsp black peppercorns
Flaky sea salt and freshly ground black pepper
For the Roasted Garlic Honey Mustard Glaze:
1 whole head of garlic
2 tbsp olive oil
60 ml (4 tbsp) runny honey
60 ml (4 tbsp) wholegrain mustard
1 tbsp Dijon mustard
Zest and juice of 1/2 a lemon
Salt and pepper to taste
To Serve (Optional):
Creamy mashed potatoes or crispy roast potatoes
Buttered seasonal greens (like kale or cavolo nero)
A robust red wine, such as Syrah or Rioja
Instructions
Part 1: Preparation & Slow Confit (5-6 hours)
1. Prep the Lamb (Optional Overnight Step):
Pat the lamb shoulder completely dry with paper towels. Using a sharp knife, score the fat cap in a cross-hatch pattern, about 1cm deep. Generously season all over with flaky sea salt. Place on a rack set over a tray, cover loosely, and refrigerate for at least 2 hours, or ideally overnight. This draws out moisture and seasons the meat deeply.
2. Preheat & Assemble:
Preheat your oven to 135°C (275°F). Take a large, heavy ovenproof dish or Dutch oven, just big enough to hold the lamb snugly. Scatter the chopped onions, carrots, the halved head of garlic, bay leaves, peppercorns, and herb sprigs over the base. Place the seasoned lamb shoulder on top, fat-side up.
3. The Confit Process:
Gently melt your chosen fat in a saucepan until just liquid. Carefully pour the warm fat over the lamb until it is almost completely submerged (the very top of the fat cap can peek out). Cover the dish tightly with a lid or a double layer of foil.
4. The Slow Cook:
Place in the low oven and leave, completely undisturbed, for 5 hours. This is a test of patience—no peeking! The magic happens slowly in the gentle heat.
5. Check for Tenderness:
After 5 hours, carefully remove the lid/foil (mind the steam). Test the lamb by inserting a fork and twisting gently; the meat should offer no resistance and begin to pull apart easily. If not, return to the oven, checking every 30 minutes until perfect.
Part 2: The Glaze & Final Roast (45 minutes)
6. Make the Roasted Garlic Glaze:
While the lamb cooks, prepare the glaze. Wrap the whole head of garlic for the glaze in foil with 1 tbsp olive oil. Roast in a corner of the oven (or at 200°C/400°F for 40 mins) until soft and golden. Once cool, squeeze the sweet cloves into a bowl. Mash with a fork and whisk in the honey, wholegrain mustard, Dijon mustard, lemon zest, and juice. Season with a pinch of salt and pepper. Set aside.
7. Crisp the Lamb:
Once the lamb is tender, increase the oven temperature to 200°C (400°F). Using two large slotted spoons or spatulas, carefully transfer the lamb to a clean, foil-lined baking tray. Reserve the precious confit fat and vegetables for another use (see notes!).
8. Apply the Glaze:
Using a pastry brush, generously coat the entire surface of the lamb with the roasted garlic honey mustard glaze.
9. The Final Roast:
Return the glazed lamb to the hot oven, uncovered, for 20-30 minutes. Baste once or twice with any remaining glaze. The goal is a sticky, caramelized, and deeply bronzed exterior.
10. Rest:
Remove the lamb from the oven, transfer to a warm platter, and tent loosely with foil. Let it rest for a full 30 minutes. This allows the intense heat to redistribute, ensuring juicy, tender meat.
Part 3: To Serve
11. Presentation:
After resting, the lamb is too tender to slice traditionally. Use two forks to pull apart large chunks, or gently carve if it holds together. Drizzle with any resting juices from the tray.
Serve immediately on a large platter, with your chosen sides, and perhaps an extra spoonful of the glaze on the side.
Chef’s Notes & Leftovers
Fat is Gold: Do not discard the strained confit fat! It is packed with flavor. Store it in the fridge and use for roasting potatoes, frying eggs, or as the base for an incredible gravy.
Leftover Magic: Shredded confit lamb is incredible in pies, pasta, on flatbreads, or in a hearty salad the next day.
Safety First: Always ensure the lamb is fully submerged in fat during the confit process to prevent any risk of bacterial growth.
