How to Make Mary Berry’s Cauliflower Soup
- Preheat the oven to 400°F and place a large baking sheet inside to heat.
- Chop the cauliflower into bite-sized florets, including the tender stems.
- Toss the cauliflower with salt and pepper and arrange in a single layer on the heated baking sheet.
- Wrap the shallots and unpeeled garlic with olive oil and a pinch of salt in aluminum foil, then place the packet on the baking sheet.
- Roast everything for 30 to 35 minutes, until the cauliflower edges are browned and tender.
- Heat the vegetable broth in a large pot over low heat.
- Transfer the roasted cauliflower, shallots, and garlic (squeezing the garlic from their skins) into the broth.
- Add the thyme leaves and simmer gently, covered, for 15 minutes.
- Let the mixture cool slightly, then transfer it to a blender.
- Blend until smooth, adding the miso paste, Dijon mustard, lemon juice, and olive oil.
- Taste and adjust seasoning with extra salt and a splash more lemon juice if desired.
- Ladle into bowls, drizzle with olive oil, and top with microgreens if using. Serve hot.

Common Mistakes to Avoid
- Skipping the roasting: roasting develops the crucial caramelized flavor.
- Not cooling slightly before blending: blending hot liquids can cause dangerous splashes.
- Underseasoning: taste as you blend and adjust with salt, pepper, and lemon.
- Overloading the blender: work in batches if needed to ensure a silky texture.
- Using low-quality broth: good broth makes a big difference in the final flavor.
Storage and Reheating Instructions
- Storage: Let the soup cool completely, then refrigerate in an airtight container for up to 5 days.
- Freezing: Freeze in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating:
- Stovetop: Warm gently over medium-low heat, stirring occasionally.
- Microwave: Heat in a microwave-safe bowl, stirring halfway through, until hot.
FAQs

Q: How do you thicken cauliflower soup naturally?

Q: Why is my cauliflower soup grainy?
A: The soup can be grainy if the cauliflower isn’t fully softened before blending. Simmer until tender.
