Slow-Roasted Persian Lamb Shoulder with Saffron Butter
Hosting a crowd? This is the dish. Prep it, put it in the oven, forget about it for five hours, and open the lid to lamb that falls off the bone and melts in your mouth.
Every holiday season, this is the recipe people ask me for most. It's perfect for Christmas, Thanksgiving, Nowruz, birthdays and dinner parties: anywhere you want to feed people something unforgettable without standing over the stove. In Persian we'd call it dahan-por-kon, literally "mouth-filling": a real show-stopper. Your guests will go back for seconds, and maybe thirds.
The magic is in two layers of flavour. Underneath, the lamb sits on a bed of onions, garlic, ginger, cinnamon, cloves, rosemary and bay that slowly perfumes the juices. On top, it's rubbed with saffron butter, turmeric, black pepper and lemon, which turns into a deep golden, glossy crust at the end.
Time
Prep: 15 min, plus 1 hour to bring the lamb to room temperature
Cook: 5 h 10 min
Rest: 10 min
Ingredients (serves 6 to 8)
For the lamb
1 whole lamb shoulder, bone in, about 2 to 2.5kg / 4.5 to 5.5lbs
3 tbsp butter, softened (or olive oil for a lighter version)
1/4 tsp ground saffron
2 ice cubes, to bloom the saffron
1 tsp turmeric
1 tsp black pepper
Juice of 1 lemon
Salt, generously
For the aromatic base
3 onions, quartered (skin on, roots trimmed)
2 whole bulbs of garlic, halved across the middle
1 thumb-sized piece of ginger, sliced
4 to 5 whole cloves (just a few: they're strong)
3 sprigs of fresh rosemary
1 to 2 red chillies, whole or halved, depending on how much heat you like
4 bay leaves
2 cinnamon sticks
You'll need
A large cast-iron casserole with a lid, or a deep roasting tray and foil
Method
1. Bloom the saffron
Sprinkle the ground saffron over the ice cubes in a small glass and set aside to melt into deep red-gold saffron water while you prepare everything else.
2. Bring the lamb to room temperature
Take the lamb out of the fridge at least 1 hour before cooking. Meat straight from the fridge cooks unevenly: the outside overcooks before the inside warms up.
3. Preheat the oven
150°C fan / 170°C conventional / 325°F / Gas 3.
4. Make the aromatic base
Scatter the onions, garlic, ginger, cloves, rosemary, chillies, bay leaves and cinnamon sticks over the bottom of the casserole or roasting tray. This is the bed the lamb sits on, and every one of these will flavour the juices.
5. Make the saffron butter rub
In a small bowl, mix the softened butter, saffron water, turmeric, black pepper, lemon juice and a generous amount of salt into a paste.
6. Rub the lamb
Pat the shoulder dry with kitchen paper. Rub the saffron butter into every surface: top, bottom, sides and into every fold. Use your hands and work it in properly.
7. Seal it tightly
Lay the lamb skin-side up on the aromatics. Put the lid on firmly, or cover the tray with two layers of foil tucked tightly around the edges. The seal is everything: this is slow braising, not roasting, and the steam needs to stay inside.
8. Five hours. Don't touch it.
Put it in the oven and walk away for 5 hours. No checking, no peeking: every time you open it you lose heat and moisture. When it's ready, the lamb will be fork-tender and falling off the bone.
9. Make the golden crust
Take off the lid or foil and turn the oven up to 180°C fan / 200°C conventional / 400°F / Gas 6. Return the lamb, uncovered, for about 10 minutes, until the top is deep golden and glossy. Keep an eye on it: every oven is different, and you don't want it to burn after 5 hours of patience.
10. Rest, then pull
Let the lamb rest in the pan for 10 minutes. Pour off the juices (strain them if you like: they're liquid gold), then pull the meat apart with two forks right in the pan and spoon the juices back over. Nooshe jan!
Three ways to serve it
The centrepiece: bring the whole casserole to the table with the lid on and lift it in front of your guests. Serve with Persian saffron rice and tahdig, fresh herbs (sabzi khordan), torshi and Salad Shirazi.
The sandwich: pile the pulled lamb into warm flatbread (barbari or sangak) with sliced red onion, chopped parsley, a squeeze of lemon and a spoon of yoghurt. The pan juices make it sing. Honestly, I sometimes make the whole thing just for this.
The feast platter: pulled lamb on a big board with roast potatoes, flatbread, herbs and pickles, family-style, so everyone helps themselves.
Hami's tips
Make it ahead: cook it the day before, cool and refrigerate in its juices, then reheat covered at 150°C fan for about 45 minutes and do the 10-minute crust just before serving.
Leftovers keep in the fridge for 3 days, and they're even better in the sandwich.
