Step 1

Preheat your oven to 425°F.

Step 2

Place the chestnuts flat side down on the cutting board. With a serrated knife, cut a little slit into the top of each one. Place the cut chestnuts into a medium sauce pan and cover them with filtered water. Bring them to a boil and then drain. Transfer drained chestnuts to a sheet pan and roast in the oven for 15-20 minutes, or until shells are coming away from the innards. Once cool enough to handle, peel chestnuts and set aside, discarding the shells.

Step 3

Lower the oven heat to 400°F. Wipe out the sheet pan used for the chestnuts. Tear kale leaves into slightly larger than bite-size pieces. Drizzle them with the olive oil and maple syrup and season with salt and pepper. Toss and massage the leaves until they are thoroughly coated. Arrange them in a single layer and sprinkle with sesame seeds. Slide the tray into the oven and bake for about 7-8 minutes, or until the kale has crisped and curled up just a little bit. Remove the kale crisps from the oven and allow to cool.

Step 4

Heat the olive oil in a large, heavy pot over medium heat. Add the onions and cook until quite soft, about 5-6 minutes. Add the garlic and stir, cooking for about 30 seconds or until fragrant. To the pot, add the salt, squash, chestnuts, water, sage, and bay leaves. Place a lid on the pot and bring to a boil. Simmer until the squash is tender, about 20 minutes. Carefully purée the soup in batches in a blender, and then return the blended soup to the large pot. Add tamari, salt, and pepper to taste. Bring the blended soup back up to a boil. Serve hot with kale sesame leaves
