Waaaay back at the beginning of this blog, I posted this Cauliflower & Leek Soup that is still one of our most popular recipes. I used cashews to make it creamy without actual cream, but since then I’ve realized that blended cauliflower can become SO creamy and delicious all by itself. Sometimes less is more, and I love the pure simple flavor of this new all-vegetable roasted cauliflower soup.
I start by roasting the whole cauliflower – florets, cores, greens and all. Waste not want not! I also roast shallots and garlic before blending it all with a bit of miso, Dijon mustard, lemon juice, and thyme for flavor. As always, the soup tastes better the second day, so it’s a perfect make-ahead meal. This one is sure to be on our rotation all winter long.
Happy roasted cauliflower soup-ing!
- 1 medium head cauliflower (about 2 lbs.)
- 2 shallots, peeled and sliced into quarters
- 4 unpeeled garlic cloves
- 4 cups (32 ounces) vegetable broth
- Leaves from 5 fresh thyme sprigs
- ½ tablespoon white miso paste
- ½ tablespoon Dijon mustard
- 3 tablespoons extra-virgin olive oil
- 2 tablespoons fresh lemon juice
- Sea salt and freshly ground black pepper
- Preheat the oven to 400°F and line a large baking sheet with parchment paper.
- Trim the cauliflower head into florets and cut the core into pieces. Spread the cauliflower and the shallots on the baking sheet and toss with a drizzle of olive oil and pinches of salt and pepper.
- Wrap the garlic cloves, along with a drizzle of olive oil and a pinch of salt, in a piece of aluminum foil and place it on the baking sheet with the vegetables. (The garlic will roast this way making it soft and the flavor less strong).
- Roast for 30 to 35 minutes or until the cauliflower is browned around the edges. Remove from the oven and let cool slightly. Set aside 1½ cups of the smaller cauliflower florets for garnish.
- In a blender, combine the roasted cauliflower, shallots, peeled garlic, vegetable broth, thyme leaves, miso paste and Dijon mustard and blend until smooth.
- Add the olive oil, lemon juice and a pinch of salt and pepper and blend. Taste and adjust seasonings adding more salt, pepper and lemon juice. If the soup is too thick, add water, a few tablespoons at a time and blend to desired consistency.
- Serve with a drizzle of olive oil and the reserved cauliflower florets.
- Note: the soup will thicken as it sits. If you’re reheating the soup, stir in a bit more water for a thinner consistency, if desired.
