2 ½ lb(s) kabocha, butternut, red kuri, or other deep orange winter squash
2 lb(s) sweet potatoes (orange or yellow-fleshed)
1 ¼ lb(s) celeriac
1 Tbsp coconut or olive oil
1 ½ cup onion, chopped
1 cup apples - peeled, cored and chopped
3 large cloves garlic, minced
tsp mild curry powder
½ tsp whole coriander seeds
¼ tsp whole fennel seeds
½ tsp sea salt
Freshly ground black pepper to taste
1 ½ Tbsp grated ginger
3 cup vegetable stock
1 cup water
1 can (400 ml) coconut milk (regular, not light)
1 Tbsp freshly squeezed lemon juice
1. Preheat oven to 450 degrees.
2. Place squash, sweet potatoes, and celeriac on a baking sheet lined with parchment paper. Bake for 55-75 minutes, or until tender when pierced with a skewer or sharp knife. (Baking time will vary depending on the size of the vegetables. Smaller sweet potatoes and squash will be tender earlier, whereas larger ones and also the celeriac will take longer time to soften. Remove those that are tender earlier while the others continue to cook) Once tender, let cool enough to handle. While vegetables are cooking/cooling, prepare other ingredients.
3. In a large soup pot, heat oil over medium heat. Add onion, apple, garlic, curry powder, coriander seeds, fennel seeds, salt, and pepper. Cover and cook for 7-9 minutes, stirring occasionally, until onions have softened.
4. Once roasted vegetables are cool enough to handle, slice squash and discard seeds. Scoop the flesh away from the peel and add to your soup pot. Cut peel away from sweet potatoes and celeriac (celeriac peel is thicker, so trim away a little of the thick, coarse peel. If the celeriac still seems a touch firm, cut it in smaller chunks so it can simmer and more quickly soften in the soup pot.) Add fresh ginger (start with 1 tbsp), stock, and water, bring mixture to a boil, reduce heat and let simmer covered for about 10 minutes, or until all the vegetables are quite tender.
5. After this time, use an immersion blender and puree the soup until smooth. Stir in the coconut milk and lemon juice and taste test. If you'd like additional ginger, stir in the remaining ½ tablespoon.
6. Season with additional salt and pepper if desired, and serve.
7. Note: You can change the proportions of squash, sweet potatoes, and celeriac as you choose. Simply keep a total weight of about 6-7 lbs, which will give you roughly 10 - 11 cups of roasted vegetable flesh (after removing skins and seeds). Note that some squash will have more flesh and less seeds (ex: butternut) than other squash that will have a larger seed cavity and less flesh (ex: red kuri squash), so measuring out the cups of roasted flesh is helpful to determine how much you are actually using.
