A velvety, creamy roasted cauliflower soup made with simple ingredients and no heavy cream. Roasting brings out deep flavor, while garlic, thyme, and a touch of lemon create a comforting, balanced soup perfect for any time of year.
Preheat the oven to 220°C / 425°F. Line a baking tray with parchment paper.
Place the cauliflower florets and chopped core onto the tray. Drizzle with olive oil, season with salt, pepper, and vegetable seasoning (if using), and toss to coat.
Wrap the garlic cloves in foil with a drizzle of olive oil. Do the same with the chopped onion. Place both foil parcels on the tray with the cauliflower.
Roast for 25–30 minutes, or until the cauliflower is tender and golden on the edges.
Simmer
Bring the vegetable stock to a gentle simmer in a large pot.
Add the roasted cauliflower, onion, and peeled garlic cloves to the pot along with fresh thyme (if using). Simmer for 15–20 minutes to allow the flavors to develop.
Blend
Remove from heat and allow to cool slightly.
Blend the soup until smooth using an immersion blender or stand blender. Return to the pot if needed and keep on low heat.
Finish and serve
Stir in the lemon juice, coconut cream (if using), and cook’s tip ingredients (turmeric paste and Dijon mustard, if using).
Taste and adjust seasoning as needed. Serve warm with your choice of garnishes.
Notes
Roasting the vegetables adds a deeper, richer flavor, but you can skip this step and cook everything in one pot if needed.
Coconut cream is optional — the soup is naturally creamy without it.
Adjust the consistency with extra stock if needed.
