This is a thick, luxurious soup with some additional texture, flavour and colour added by a layer of roasted vegetables. The cauliflower gives the soup good density, and its surface tension is increased by the arrowroot. The thinly sliced potatoes work like a raft distributing the weight of the roasted vegetables, themselves lightened by loosing their water weight through roasting.
For the roasted vegetables
4 small yellow potatoes, thinly sliced (about 1 1/2 cups)
1 small red pepper, cored, seed and thinly sliced (about 1/2 cups)
1 scallion, minced (reserve about 3″ of green for garnish)
2 cups of shredded cabbage
4 small cremini mushrooms, stemmed and thinly sliced (about 50g)
1T of cooking oil
2t of lemon juice
1/2t of coarse sea salt
Sea salt and black pepper to taste
For the soup
1T of cooking oil
1/4t of coarse sea salt
1T of garlic, minced
3 cups of cauliflower florets
2 cups of vegetable stock
2 cups of unsweetened soy milk
2T of nutritional yeast
1T of arrowroot powder whisked with 2T of water
Sea salt and black pepper to taste
Start with the roasted vegetables, then make the soup
Preheat the oven to 400F.
Slice the potatoes in about 1/8″ slices, lengthwise. Reserve the ends; throw them in with the soup.
Slice the red pepper in about 1/4″ slices, and the mushrooms in about 1/8″ slices.
Mince the scallions and shred the cabbage (I use coleslaw mix).
Whisk the oil, lemon juice and sea salt.
Toss the sliced vegetables in their lemon and oil dressing.
Spread the vegetables evening on an oven pan with sides.
Roast for about 30 – 40 minutes or until everything is lightly browning.
Season the vegetables to taste.
While the vegetables cooking, make the soup.
Bring the oil to heat with 1/4t of coarse sea salt.
Add the garlic and saute for 2 minutes.
Add the cauliflower and potato ends and saute for about 5 minutes until the pan is lightly browning.
Add the stock and the soy milk.
Return the pan to a low boil and simmer for about 25 minutes or until the cauliflower is tender.
Add the nutritional yeast.
Puree the soup.
Season to taste.
Whisk the arrowroot with the water.
Return the soup to low heat.
Add the arrowroot mixture slowly stirring continuously until it thickens.
Let the soup stand about 5 minutes and let the vegetables rest at least five minutes before serving.
To serve, arrange the potatoes in a thin layer on the surface of the soup (like a raft).
Carefully spoon the other roasted vegetables onto the potatoes, trying not to sink them, although if they sink a little, it’s not a crisis. You should still have enough vegetable to make a nice, nuanced presentation.
Garnish with the sliced scallions greens.
Makes two large bowls or four smaller ones.
