1. Heat oil in a large pot over medium heat. Add the chopped onion and cook for 5 minutes until softened and starting to turn golden at the edges.
2. Add the minced garlic and grated ginger and cook for 1 minute until deeply fragrant.
3. Add the cubed lamb shoulder and brown properly on all sides — work in batches if needed and give each piece real contact with the pot.
4. Add the chopped tomatoes, turmeric, cumin, coriander, and chili powder. Stir well to coat the lamb and cook for 2 minutes until the spices are fragrant and slightly darker.
5. Pour in the coconut milk and add the cashews. Season with salt and pepper and stir everything together.
6. Cover, reduce heat to low, and simmer for 1.5 to 2 hours until the lamb is completely tender and the cashews have softened into the sauce.
7. Taste and adjust seasoning as needed.
8. Serve over cooked rice and garnish generously with fresh cilantro.

Notes:

• Raw unsalted cashews are essential — roasted ones can turn bitter and salted ones throw off seasoning balance.
• Full-fat coconut milk is non-negotiable — lite produces a thin sauce that can’t carry this curry properly.
• Brown the lamb in batches if needed — crowding the pot means steaming not searing, which kills the flavor depth.
• Old ground spices contribute almost nothing — fresh cumin and coriander make a genuinely noticeable difference here.

Storage Tips:

• Refrigerate in an airtight container for up to 3 days — flavor deepens and improves overnight.
• Freeze for up to 3 months — cool completely before storing in airtight containers.
• Reheat on the stovetop over low heat with a splash of coconut milk or water to loosen the sauce.
• Add fresh cilantro after reheating, never before storing.

Serving Suggestions:

• Serve over basmati or jasmine rice to soak up every drop of that gorgeous cashew coconut sauce.
• Warm naan or roti on the side is perfect for scooping the thick, fragrant sauce straight from the bowl.
• A dollop of plain yogurt on top adds a beautifully cooling contrast to the warmth of the spices.
• A final scatter of roughly chopped cashews alongside the fresh cilantro adds beautiful texture and visual contrast right at the table.

Mix It Up:

• Smooth Lamb and Cashew Curry: Blend half the finished sauce with an immersion blender for a silky, restaurant-worthy texture that completely impresses.
• Festive Spiced Lamb and Cashew Curry: Add cinnamon and cardamom with the other spices for a warmly aromatic holiday version.
• Spicy Cashew Lamb Curry: Double the chili powder and add a fresh chopped green chili with the garlic for a heat-forward version that plays beautifully against the creamy sauce.
• Chickpea and Cashew Curry: Swap lamb for chickpeas and reduce simmer time to 30 minutes for a plant-based version that’s just as creamy and fragrant.

What Makes This Recipe Special: This lamb and cashew curry draws on centuries of Mughlai culinary tradition where nut-based sauces were used to create the kind of opulent, velvety richness that defined royal court cooking across the Indian subcontinent. Cooking whole cashews directly in the coconut milk for the full braising time — rather than adding them as a garnish — allows them to slowly release their natural oils and creaminess into the sauce in a way that transforms it entirely, creating a depth and body that coconut milk alone cannot achieve. Combined with properly caramelized lamb shoulder that becomes genuinely fall-apart tender after two patient hours, this is a curry that rewards every minute of the wait with something truly extraordinary in the bowl.
