Step 1

Preheat oven to 350°. Toast coconut flakes on a rimmed baking sheet, tossing occasionally, until golden brown, 3–5 minutes; transfer to a small bowl. Toast pumpkin seeds on baking sheet, tossing occasionally, until golden brown, 4–6 minutes. Let cool slightly, coarsely chop, and add to bowl with coconut flakes; set aside.

Step 2

Increase oven temperature to 450°. Toss squash, onion, chile, garlic, coconut oil, and vadouvan in a large bowl until squash is coated (it’s okay if the oil solidifies after tossing); season with salt and pepper. Arrange in a single layer on baking sheet and roast, tossing occasionally, until squash and onion are browned and tender, 40–50 minutes.

Step 3

Meanwhile, add cilantro and orange zest to reserved coconut flakes and pumpkin seeds and stir to combine. Season with salt and pepper and cover.

Step 4

Peel garlic, then purée garlic, squash, onion, chile, coconut milk, and 2 cups hot water in a blender until smooth, adding more water if needed. Season with salt and pepper. Serve soup topped with cilantro mixture.
