There’s something reliably comforting about a bowl of soup on a cold day, especially when it’s properly warm, smooth and finished with something that wakes everything up a little.

This roasted cauliflower soup keeps things simple. Frozen cauliflower makes it easy enough for midweek cooking, while roasting brings out a deeper, sweeter flavour that feels far richer than the ingredient list suggests.

The real lift comes from the chipotle oil - smoky, slightly spicy and just sharp enough to cut through the creaminess of the soup without overpowering it.

It’s the sort of lunch or light dinner that feels cosy without being heavy.

Serves 2

Roasted Cauliflower Soup

You’ll Need

• 700g frozen cauliflower
• 2 tbsp olive oil
• 2 garlic cloves, unpeeled
• 1 onion, chopped
• ½ celery stalk, chopped
• 800ml chicken or vegetable stock
• 3 tbsp single cream
• Salt

To Make

• Preheat the oven to 210°C.
• Toss the frozen cauliflower with 1 tablespoon of olive oil and a generous pinch of salt, then spread onto a baking tray. Roast for 25–35 minutes until deeply golden around the edges.
• Meanwhile, heat the remaining olive oil in a saucepan over a medium heat. Add the onion and celery and cook gently until softened.
• Add the roasted cauliflower to the pan along with the garlic cloves, squeezing the softened garlic from their skins as you go.
• Pour in the stock and simmer gently for 15–20 minutes until everything is soft and properly combined.
• Blend until completely smooth, then stir through the cream and keep warm.

Why This Soup Works

Roasting cauliflower changes it completely. The edges caramelise slightly, bringing sweetness and depth that boiled cauliflower never quite manages.

The soup itself stays simple and comforting, while the chipotle oil adds contrast -  smoky heat, richness and just enough sharpness to stop everything feeling too heavy.

Using frozen cauliflower also means the texture stays consistent year-round, making it an easy soup to throw together without much planning.

To Serve

Ladle into bowls and finish generously with the warm chipotle oil.

Serve with cheese scones, toasted sourdough or something crisp enough for dipping.

Easy Swaps

• Use oat cream for a dairy-free version
• Add parmesan before blending for extra richness
• Swap chipotle for chilli crisp if preferred
• Top with crispy onions or toasted seeds for texture

FAQs

Can I use fresh cauliflower?

Yes. Fresh cauliflower works perfectly, though you may need slightly less roasting time.

Is chipotle very spicy?

Chipotle in adobo brings more smokiness than heat, though you can adjust the amount depending on preference.

Can I freeze the soup?

Yes - freeze before adding the cream for the best texture.

What does roasting the cauliflower do?

Roasting brings out sweetness and gives the soup a much deeper flavour than steaming or boiling alone.
