A whole butternut squash is cubed and tossed with walnut oil, cumin, coriander, crushed chillies, Madras curry powder, salt and pepper, then roasted hot to caramelise the edges and toast the spices. Meanwhile, a base of red onion, ginger, fresh chilli, garlic and coriander stalks softens in oil with another hit of curry powder, then meets diced tomatoes and chickpeas in the slow cooker for a low simmer. The roasted squash goes in for the last stretch so it keeps its shape, and the curry is served over turmeric rice scattered with the reserved coriander leaves.
Slow cooker notes: Tim's original is hob-and-oven. The slow cooker version keeps the 40-minute squash roast at 190C because that is where the spice and caramelisation come from. The aromatics are still softened in a pan first to bloom the curry powder, then the base goes into the slow cooker with the tomatoes and chickpeas for a long low cook. The roasted squash joins for the last 30 minutes only, to stop it falling apart.

Method
Heat the oven to 190C. Cube the butternut squash and toss in a roasting tray with the walnut oil, cumin, coriander, crushed chillies, Madras curry powder, salt and pepper until evenly coated.
~8 minRoast for 40 minutes until tender and caught at the edges. Set aside.
~40 minWhile the squash roasts, sweat the red onion, ginger, chilli, garlic and coriander stalks in a pan with oil on a medium-low heat until soft and caramelising.
~10 minStir in the second 2 tsp of Madras curry powder and let it bloom for a minute.
~1 minTip the softened base into the slow cooker. Add the diced tomatoes and drained chickpeas.
~2 minCover and cook on low for 4 to 5 hours or on high for 2.5 to 3 hours, splashing in boiling water or stock if it looks dry.
~300 minStir the roasted butternut squash through and continue on low for 30 minutes so the squash warms through but holds its shape.
~30 minCook the rice with the half teaspoon of turmeric for the yellow colour. Serve the curry over the rice with the reserved coriander leaves on top.
