Prepare the Squash: Preheat the oven 400 F. Cut both ends off the squash, peel it, then cut in half crosswise so you have the top and bottom as two pieces. Slice each piece in half down the center vertically, so that you now have 4 pieces of squash. Use a spoon to scoop out and discard the seeds and pulp. Cut the squash into ¾-inch pieces.
Roast Squash: Transfer squash to a baking sheet. Drizzle with 1 tsp oil, then season with 1 tsp of the curry powder and a pinch of salt and pepper. Toss to coat. Roast on the middle rack of the oven for 24-28 min, stirring halfway, until tender and golden-brown. Roasting the squash caramelizes the natural sugars, intensifying the flavour.
Saute Shallot: While the squash roasts, in a large pot, heat 1 tbsp coconut oil over medium heat. When the pot is hot, add the shallots. Cook for 3-5 min, stirring often, until tender.
Add Ginger, Garlic & Spices: Add garlic, ginger, 1 tsp curry powder and curry paste. Cook for another 1-2 mins, stirring constantly, to toast the spices.
Add Liquids & Chickpeas: Add tomatoes, chickpeas, coconut milk and 1 cup of the broth, scraping bottom of the pot to loosen all the brown bits. Season with salt and pepper. Bring to a simmer over high heat. Once simmering, reduce heat to medium-low. Cook for 12-15 mins, until slightly reduced.
Optional - Blend Curry: If you'd like the curry to be thicker, scoop about 2 cups of the curry into a blender and add about 1 cup of the roasted butternut squash. Blend until smooth then pour back into the pot. You can also pulse an immersion blender in the pot a few times after adding the squash but before adding the spinach. This step is optional.
Finish Curry: Add the spinach, soy sauce and coconut sugar. Cook for another 2-4 min, stirring occasionally, until spinach wilts and flavours are combined. Add the butternut squash, lime juice and chopped cilantro. Adjust the consistency with additional broth, if desired.
Serve Curry: Divide curry between bowls alongside rice of choice. Top with remaining more cilantro, lime and peanuts, if desired.
