Jamie Oliver Cauliflower And Leek Soup

Right, so here’s the thing — cauliflower gets such a bad rap. It’s like the beige cardigan of the veg world. Everyone’s got one lurking at the back of the fridge, but no one’s particularly excited about it. Until this soup, that is. This roasted cauliflower and leek number? It’s like giving that cardigan a bold lipstick and sending it dancing into a French bistro. Magic.

The first time I made it, I was half-ignoring the recipe and half-listening to my neighbour rant about her compost bin (as you do). I tossed some veg on a tray, soaked some cashews in whatever I could find, and hoped for the best. And honestly? The smell that came out of the oven was enough to silence even the bin drama. Toasty, sweet, garlicky — you could bottle it.

There’s something almost smugly satisfying about blitzing all those roasted bits into creamy gold with barely any effort. And I know miso sounds posh or precious, but trust me — even a teaspoon lifts the whole thing like a little chef’s kiss.

Why You’ll Love It

• Roasted flavour = big flavour — no bland cauliflower here
• Creamy without cream — cashews do the heavy lifting
• Only one tray and one blender to wash — bless
• Freezer-friendly — if it even makes it that far
• Flexible with swaps — use beans, skip nuts, tweak away
• Proper posh for dinner parties, but dead easy too

Ingredients

• About 2 cups chopped cauliflower
• 2–3 leeks, white and pale green bits only, chopped
• 2 garlic cloves, peeled
• Olive oil, for roasting and blending
• ½ cup raw cashews, soaked overnight (or quick-boiled if you forgot)
• 1½ tsp white or yellow miso paste (or just use salt if you’re out)
• A few leaves of marjoram or thyme — fresh if you’ve got ’em
• 3 cups water (or broth, if you’re feeling extra)
• 2 tbsp more olive oil (goes in at the blending stage)
• ⅛ tsp smoked paprika (or a proper pinch if you like drama)
• Squeeze of lemon
• Salt and pepper, to taste
• Red pepper flakes (optional — but yes)
• Splash of white wine or champagne vinegar, for that finishing zing

How to Make It

Roast your veg to golden goodness:

Preheat the oven to 400°F (200°C). Chuck the cauliflower, leeks, and garlic onto a baking tray. Drizzle with olive oil, sprinkle with salt and pepper, and toss everything about. Roast for 25-ish minutes, flipping halfway. You want golden edges, but if a leek or two gets a bit too crispy, don’t panic — just ditch the black bits.

Prep your blender bits:

In your blender, combine the roasted veg, drained cashews, miso, fresh herbs, lemon juice, and about half the water (1½ cups). Blend until velvety. This might take a minute — literally.

Add richness and final flavour:

Add the remaining water, 2 tbsp of olive oil, and the paprika. Blend again. Taste and tweak — does it need more salt? More lemon? A tiny splash of vinegar to wake it up?

Warm it through gently:

Pour your glorious golden soup into a pan and warm it up over low heat. If it’s too thick for your liking, just loosen it with a splash of water. If it’s too thin, maybe roast another cauliflower next time (kidding — kinda).

Serve it up, fancy or not:

Serve hot, sprinkled with red pepper flakes, maybe a drizzle of olive oil, and absolutely with a hunk of crusty bread. This soup wants bread. Craves it, really.

Common Mistakes and How to Dodge Them

My soup tastes a bit flat — help?
It probably needs acid. Add a squeeze more lemon or that vinegar splash. Works wonders.

I forgot to soak the cashews — now what?
No stress. Just simmer them in hot water for 20–30 mins while your veg roasts. Or blend longer in a high-speed blender.

It’s too thick/thin/just weird. What now?
Too thick? Add water or broth. Too thin? Simmer it a bit to reduce. Weird? Check your miso quantity — a little goes a long way.

Why does it taste like cashew butter?
You probably used roasted or salted cashews. You need plain raw ones, love. Otherwise, it leans too nutty.

Texture’s not silky — help?
That’s the blender. A weaker one can leave it a bit grainy. You can strain it, but honestly, try to embrace the rustic vibe.

Storage and Reheating

• Fridge: Keeps for 4–5 days in a sealed container.
• Freezer: Skip the lemon/vinegar if freezing, then add fresh when reheating. It keeps beautifully for up to 3 months.
• Microwave: 2-minute blast, stir, then another 1–2 minutes.
• Stovetop: Low heat, gentle stir. Add a splash of water if it thickened overnight.
• Air fryer: I mean… don’t. Unless you’re toasting your bread in it.

Frequently Asked Questions

Can I use broth instead of water?
Yes! It deepens the flavour and makes it feel fancier.

Is there a nut-free version?
Absolutely. White beans work a treat. Just make sure they’re soft and drained before blending.

Can I make it ahead for a dinner party?
Yes, and it actually gets better as it sits. Just reheat gently and stir well.

What if I only have dried herbs?
Use ½ tsp dried thyme or marjoram. Add to the blender. Not quite as bright, but still lush.
