Introduction

This fall-apart Massaman lamb shoulder is a rich and aromatic dish perfect for cozy dinners. Slow-roasted with fragrant spices and coconut milk, the lamb becomes tender and bursting with flavor. Serve it with jasmine rice for a comforting meal that feels special yet easy to prepare.

Ingredients

• 2–2.25 kg (4–4.5 lb) lamb shoulder, bone-in, excess fat trimmed but leaving a thin layer
• 114 g (4 oz / ½ cup) Maesri Massaman curry paste (or other brand)
• 400 g (14 oz) can full-fat coconut milk
• 3 cups low-sodium chicken stock or broth
• 1 onion, halved then cut into 1 cm (½ inch) thick wedges
• 2 cinnamon sticks (or ½ tsp cinnamon powder)
• 2 star anise (optional)
• 600 g (1.2 lb) small baby potatoes, whole
• 2 large red chillis, finely sliced diagonally (optional)
• 1 cup lightly packed coriander leaves and sprigs (cilantro), highly recommended
• Jasmine rice (or basmati) to serve

Instructions

1. Step 1: Preheat your oven to 220°C (425°F) or 200°C (fan-forced).
2. Step 2: In a pan, whisk together the Massaman curry paste, coconut milk, and chicken stock until smooth and lump-free.
3. Step 3: Place the lamb shoulder in the pan and turn it to completely coat in the sauce. Position the lamb upside down so the meaty or fat side is facing down.
4. Step 4: Arrange the onion wedges, cinnamon sticks, star anise, and baby potatoes around the lamb. Cover the pan tightly with foil.
5. Step 5: Roast in the oven for 1 hour at 220°C (425°F), then lower the temperature to 180°C (350°F) or 160°C fan and continue roasting for another 3 hours until the lamb is fall-apart tender.
6. Step 6: Remove the foil and check tenderness by shredding the meat with forks. If it’s not tender enough, cover and keep cooking until it is.
7. Step 7: Turn the lamb over, spoon some of the sauce over it, and bake uncovered for an additional 30 minutes or until the surface is deep golden brown.
8. Step 8: Let the lamb rest for 10–15 minutes. Skim off any excess fat from the surface and discard.
9. Step 9: Stir the sauce gently (it will be somewhat runny) and transfer everything to a serving dish. Garnish with sliced chillis and coriander leaves if desired. Serve with jasmine rice.

Tips & Variations

• Using bone-in lamb shoulder with a thin fat layer helps keep the meat moist and flavorful during slow cooking.
• If you don’t have star anise, the dish will still taste great without it.
• Instead of baby potatoes, try using whole baby carrots or sweet potatoes for a different twist.
• The sauce can be thickened by simmering it on the stove after cooking, but keeping it slightly runny balances the rich flavors.
• Serve with basmati rice for a nuttier flavor variation instead of jasmine rice.

Storage

Store leftover lamb and sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the oven to avoid drying out the meat. This dish also freezes well for up to 2 months; thaw overnight in the refrigerator before reheating.

FAQs

Can I use boneless lamb shoulder instead?

Yes, boneless lamb shoulder will work, but cooking times may be slightly shorter. Keep an eye on the tenderness to avoid overcooking.

Is this dish spicy?

The Massaman curry paste is mildly spiced and aromatic rather than hot; adding sliced red chillis is optional if you prefer a little heat.

Ingredients

Scale 1x2x3x

Lamb and Curry:

• 2–2.25kg (4 – 4.5 lb) lamb shoulder, bone in, excess fat trimmed but leave a thin fat layer
• 114g (4 oz / 1/2 cup) Maesri Massaman curry paste (1 can) or other brand
• 400g (14 oz can) coconut milk, full fat
• 3 cups low sodium chicken stock/broth

Vegetables and Spices:

• 1 onion, halved then cut into 1 cm (1/2″) thick wedges
• 2 cinnamon sticks (or 1/2 tsp cinnamon powder)
• 2 star anise (optional)
• 600g (1.2 lb) small baby potatoes, whole (do not cut into cubes)
• 2 large red chillis, finely sliced diagonally (optional)
• 1 cup lightly packed coriander leaves and sprigs (cilantro), highly recommended

To Serve:

• Jasmine rice or basmati rice

Instructions

1. Preheat the oven: Set your oven to 220°C/425°F (200°C fan-forced) to prepare for the initial roasting stage.
2. Prepare the curry sauce and lamb: Whisk together the Massaman curry paste, coconut milk, and chicken stock in a pan until smooth and lump-free. Place the lamb shoulder into the mixture and turn it to coat well. Position the lamb upside down in the pan, with the meaty, fatty side down.
3. Add vegetables and spices: Arrange the onion wedges, cinnamon sticks, star anise, and whole baby potatoes around the lamb. Cover everything tightly with foil to trap moisture.
4. Roast slow-cook: Roast the covered dish at 220°C/425°F for 1 hour, then reduce the oven temperature to 180°C/350°F (160°C fan) and continue roasting covered for an additional 3 hours. This slow roasting tenderizes the lamb.
5. Check tenderness: Remove the foil and test the lamb with forks; it should be very tender and fall-apart. If not, recover and continue roasting until tender.
6. Brown the lamb: Turn the lamb over so the meaty side faces up. Spoon sauce over the lamb, then return it to the oven uncovered and bake for 30 minutes or until the lamb develops a deep golden color and a slight crust.
7. Rest and serve: Let the lamb rest for 10-15 minutes after removing it from the oven. Skim off any excess fat from the surface of the sauce and discard. Stir the sauce well to mix flavors. Transfer the lamb, potatoes, and sauce to a serving dish, garnish with sliced red chillis and fresh coriander leaves. Serve alongside fragrant jasmine or basmati rice for a complete meal.

Notes

• Note 1: Leaving a thin layer of fat on the lamb shoulder helps keep the meat moist and flavorful during cooking.
• Note 2: Maesri is a popular brand of Massaman curry paste; however, other brands can be used if desired.
• Note 3: Full-fat coconut milk ensures a rich and creamy curry sauce.
• Note 4: Use small baby potatoes whole instead of cubed to maintain texture and prevent them from disintegrating.
• Note 5: The initial high heat roasting creates a crust and seals in flavors before the long slow cooking.
• Note 6: If the sauce is too thin after cooking, it can be reduced by simmering uncovered; if too thick, add a little extra stock to loosen.
• Note 7: This dish pairs beautifully with light, fluffy jasmine or basmati rice to soak up the rich sauce.
