Cauliflower-Cashew Soup with Crispy Buckwheat

This velvety cauliflower and cashew soup with crispy buckwheat is a sophisticated take on a plant-based classic. By simmering the cauliflower with cashews and vegetable stock, the soup achieves a rich, creamy texture without the need for dairy. The addition of dry white wine and fresh thyme provides an elegant depth of flavour, making it a wonderful starter for a winter dinner party or a comforting, healthy lunch during the colder months.

What sets this vegan soup apart is the savoury, toasted garnish. A mixture of buckwheat groats, finely chopped cauliflower and cashews provides a satisfying crunch and a hint of smoky heat from the paprika. This nutritious dish can be made in advance and kept in the fridge for two days, or frozen for up to a month, making it a practical choice for batch cooking.

How to make Cauliflower-Cashew Soup with Crispy Buckwheat

Heat 60ml oil in a large heavy pot over medium. Add shallots, garlic, bay leaves, and thyme; season with salt. Cook, stirring occasionally, until shallots are translucent, 6–8 minutes.

Add wine, bring to a boil, and cook until reduced by half, about 4 minutes.

Set 3/4 cup cauliflower aside; add the rest to pot along with cayenne and 110g cashews; season with salt.

Cover pot, reduce heat to low, and cook, shaking pot occasionally, until cauliflower is fork-tender and vegetables have released all their water, 20–25 minutes (check occasionally to make sure vegetables are not browning; reduce heat if they are).

Add stock and season with salt and black pepper. Bring to a boil, reduce heat, and simmer, partially covered, until cauliflower is falling apart, 20–25 minutes. Discard bay leaves. Remove from heat and let cool slightly.

Meanwhile, finely chop reserved 3/4 cup cauliflower and remaining 2 tablespoons cashews. Heat remaining 60ml oil in a small skillet over medium. Add cauliflower, cashews, and buckwheat; season with salt. Cook, stirring often, until cauliflower and cashews are golden brown and buckwheat is browned and crisp, 5–8 minutes. Remove from heat and stir in lemon juice and paprika. Let cool slightly.

Working in batches if needed, purée soup in a blender until very smooth. Return to pot and reheat over mediumlow, stirring and adding more stock to thin if needed (soup should be the consistency of double cream). Taste and season soup again if needed.

Serve soup topped with toasted cauliflower-buckwheat mixture.

Do ahead: Soup can be made 2 days ahead (or 1 month if frozen). Let cool; transfer to airtight containers and chill.
