Vegetables
- 1 small to medium-sized cauliflower
- ½ large kabocha squash (or a small onion squash or a chunk of Crown Prince)
- 1 large onion, roughly chopped
- 1 head garlic
- 2 tablespoons roughly chopped sage (plus a few finely ribboned leaves to finish)
Other Ingredients
- 2 tablespoons olive or vegetable oil
- 1 liter vegetable stock (hot or warm)
- 1 teaspoon salt
- 1 teaspoon black pepper
- Optional garnish: drizzle of coconut milk
- Preheat Oven and Prepare Tray: Preheat your oven to 390°F (200°C) and line a large baking tray with foil to prevent sticking and make cleanup easier.
- Prepare Cauliflower: Remove any damaged or tough leaves from the cauliflower and trim the stalk’s end. Roughly chop the entire cauliflower—including stem, leaves, and florets—and spread evenly on the prepared tray.
- Prepare Squash and Garlic: Peel and deseed the kabocha squash, then cut it into bite-sized chunks and add to the tray. Cut the top off the garlic head, place it on a piece of foil, drizzle with 1 tablespoon olive oil, and loosely wrap the foil around it to roast.
- Add Onion, Sage, and Oil: Scatter the roughly chopped onion and chopped sage over the veggies on the tray. Drizzle with remaining olive oil, season with salt and pepper, and toss everything together to coat.
- Roast Vegetables: Roast the vegetables and garlic at 390°F (200°C) for about 45 minutes, stirring halfway through. Roast until the vegetables are soft and caramelized, especially the cauliflower, for richer flavor.
- Blend Soup in Batches: Once roasted, blend half the vegetables with half the hot vegetable stock in a blender until smooth. Transfer to a large saucepan. Repeat with the remaining vegetables and stock. Optionally, reserve some roasted cauliflower for garnish.
- Adjust Consistency and Season: Combine the two batches of puréed soup and add hot water as needed to reach your desired thickness. Taste and adjust seasoning with more salt and pepper if necessary. Reheat gently if needed.
- Serve and Garnish: Ladle the soup into warmed bowls. Top with reserved roasted cauliflower, a few fresh sage leaves, and a drizzle of coconut milk if desired for added creaminess and flavor.
Notes
- Using warm or hot stock helps blend ingredients to a smooth texture quickly without cooling the soup too much.
- Roasting vegetables adds natural sweetness and depth of flavor to the soup.
- The soup can be thinned or thickened by adjusting the amount of stock or water added.
