Lamb Shank Massaman Curry
There's a moment, about two and a half hours into cooking this dish, when your kitchen smells so impossibly good that people will wander in from other rooms just to investigate. That's the power of Massaman curry — and when you pair it with slow-cooked lamb shanks, it becomes something truly special.
This is the kind of recipe that looks impressive but doesn't ask much of you. A little browning, a little stirring, then the oven does the rest. What comes out is a pot of fall-apart tender lamb drenched in a rich, fragrant coconut sauce that begs to be mopped up with jasmine rice.
What Makes Massaman Different?
Not all Thai curries are alike. While green and red curries bring the heat, Massaman plays a longer, more complex game. It's mild, deeply aromatic, and carries a warmth that comes from cinnamon, cardamom, and cloves — spices more commonly associated with the Middle East than Southeast Asia.
That's no coincidence. Massaman curry is believed to have arrived in Thailand centuries ago via Persian and Indian spice traders, and the name itself — derived from Mussulman, the Thai word for Muslim — reflects that heritage. The result is a curry unlike any other: rich without being heavy, warming without being fiery, and deeply, deeply satisfying.
Why Lamb Shanks?
You could make Massaman with beef, chicken, or vegetables, and it would still be delicious. But lamb shanks? That's the match you didn't know you were looking for.
Taken from the lower leg, shanks are loaded with connective tissue that slowly breaks down during cooking, turning the meat tender and silky while releasing collagen into the sauce. The result is a curry that's richer, glossier, and more unctuous than you'd ever get with a quicker-cooking cut.
- Hind shanks are larger and meatier — ideal if you're feeding a crowd and serving family-style.
- Foreshanks are smaller and more elegant — perfect if you want to plate one shank per person for a dinner party.
Either way, the long, slow cook is non-negotiable. Give it time, and the lamb will reward you.
Key Ingredients
Here’s a breakdown of the essential ingredients that bring this dish to life:
- Lamb Shanks: The star of the dish. Slow-cooking lamb shanks in a flavourful curry sauce allows the meat to become incredibly tender, with the bone providing extra richness to the dish.
- Massaman Curry Paste: The heart of the dish, made from a blend of herbs, spices, and aromatics like lemongrass, galangal, chillies, and the warming spices mentioned earlier. For convenience, using a pre-made paste like Mae Jum’s Thai Massaman Curry Paste ensures that you get all the authentic flavours without the hassle of making your own.
- Coconut Milk: Coconut milk adds creaminess to the curry, balancing the spices with its mild sweetness and contributing to the rich sauce.
- Potatoes and Onions: These vegetables not only bulk up the dish but also absorb the flavours of the curry as they cook. The potatoes, in particular, offer a delightful contrast in texture to the tender lamb.
- Peanuts: Roasted peanuts are a key ingredient in Massaman curry, offering a crunchy texture and a subtle nutty flavour that enhances the richness of the dish.
- Palm Sugar, Fish Sauce, and Tamarind: These ingredients provide the balance of sweet, salty, and sour flavours that are characteristic of Thai cuisine. Palm sugar adds a gentle sweetness, while fish sauce contributes umami, and tamarind brings a touch of sourness to balance the richness.
Cooking Method
1. Preparing the Lamb Shanks
Begin by preheating your oven to 170°C. Heat a little oil in a saucepan and sear the lamb shanks on all sides. This step locks in the meat’s juices and creates a nice browned surface that will enhance the flavour of the final dish.
2. Creating the Massaman Curry Base
In a wok or large saucepan, heat a tablespoon of the thick layer of coconut milk (taken from the top of the can) and fry the Massaman curry paste for a couple of minutes until fragrant. The heat helps release the essential oils from the paste, intensifying its flavour.
Next, add the fish sauce, palm sugar, and tamarind juice, stirring well to combine. After a minute or so, add the remaining coconut milk and mix everything together.
3. Combining and Slow-Cooking
Pour the Massaman curry sauce and stock into a large oven dish, then place the seared lamb shanks in the centre. Arrange the potatoes and onions around the lamb. Cover the dish with a lid or foil and place it in the preheated oven.
For foreshanks (300-450g each), cook for around 2 hours, with 1 hour covered and another hour uncovered. For larger hind shanks (600-750g each), you will need to cook them for about 2 hours covered and an additional 1.5 hours uncovered.
4. Adding Tomatoes and Peanuts
After the lamb has been cooking for 2 hours, check the meat and turn the shanks so that the other side is submerged in the curry sauce. Add the cherry tomatoes and peanuts to the dish. The tomatoes will bring a sweet and sour burst, while the peanuts add a lovely crunch and nuttiness.
Return the dish to the oven, uncovered, for another hour to 1.5 hours. During this time, the curry sauce will reduce and thicken, intensifying the flavours and creating a beautiful glaze on the lamb shanks.
5. Finishing Touches
Once the lamb is tender and falling off the bone, remove the dish from the oven. You can serve the lamb shank Massaman curry on its own or pair it with steamed jasmine rice to soak up all the delicious sauce. Garnish with freshly chopped coriander or red chillies if you like a bit of extra heat.
Why This Dish Is Perfect for Special Occasions
Lamb shanks are often seen as a more indulgent cut of meat, making them perfect for special occasions or dinner parties. The slow-cooking process may take a little time, but the result is well worth the wait. The lamb becomes incredibly tender, and the rich Massaman curry sauce makes for a luxurious dish that feels both comforting and decadent.
This dish is also ideal for sharing. Since lamb shanks are quite large, one shank can easily serve two people, or you can serve a smaller shank per person if you’re hosting a larger group. With its complex flavours and beautiful presentation, Lamb Shank Massaman Curry is sure to impress your guests.
Customising the Recipe
One of the best things about Massaman curry is its versatility. While lamb shanks work perfectly with the rich sauce, you can also adapt the recipe to use beef, chicken, or even vegetables for a vegetarian version. The slow-cooking method will remain the same, allowing the flavours to develop and the meat or vegetables to become tender.
You can also adjust the spice level to suit your taste. While Massaman curry is typically mild, you can add fresh red chillies or a sprinkle of chilli flakes if you prefer a little heat.
Final Thought
Lamb Shank Massaman Curry is a dish that brings together the best of Thai flavours with the comforting, rich texture of slow-cooked lamb. Whether you’re preparing it for a cosy family dinner or an elegant dinner party, this recipe is sure to impress with its tender, flavourful meat and luxurious curry sauce.
