This Mary Berry Cauliflower Soup Recipe turns humble cauliflower florets into a sophisticated, velvety starter using a classic roux base and savory chicken stock. Finished with a splash of milk for creaminess without the heavy cream, it offers a light yet deeply comforting flavor profile that is perfect for a refined lunch or light supper.
Mary Berry Cauliflower Soup Ingredients
The Soup Base:
- 1 large Cauliflower: Trimmed and broken into small florets. The stalk can be chopped and used too, as it adds flavor.
- 1 large Onion: Chopped roughly.
- 50g (2 oz) Butter: For sautéing the vegetables and creating the roux.
- 40g (1 ½ oz) Plain Flour: This thickens the soup, giving it a smooth body.
- 900ml (1 ½ pints) Chicken or Vegetable Stock: Hot. A good quality stock is essential for depth.
- 600ml (1 pint) Milk: Adds a creamy, white finish and richness.
- Salt and Freshly Ground Black Pepper: To taste.
- Optional Garnish: Crispy bacon bits or toasted croutons.

How To Make Mary Berry Cauliflower Soup
- Sauté the Onion: Melt the butter in a large saucepan over medium heat. Add the chopped onion and cook gently for about 5 minutes until soft and translucent, but not browned.
- Add Cauliflower: Add the cauliflower florets to the pan. Stir well to coat them in the buttery onion mixture. Cover the pan with a lid and let the vegetables “sweat” over low heat for 10 minutes. This step intensifies the flavor before liquid is added.
- Make the Roux: Sprinkle the flour over the vegetables. Stir constantly for 1 minute to cook out the raw flour taste.
- Add Liquid: Gradually pour in the hot stock and the milk, stirring continuously to prevent lumps from forming. Bring the mixture to a boil, stirring until thickened.
- Simmer: Season with salt and pepper. Reduce the heat to a simmer, partially cover, and cook for 20-25 minutes until the cauliflower is completely soft and tender.
- Blend: Remove from the heat. Allow to cool slightly, then blend the soup using a liquidizer or stick blender until completely smooth and silky.
- Finish: Return the soup to the clean pan to reheat gently. Taste and adjust the seasoning. Serve piping hot.

Recipe Tips
- Sweating the Veg: Don’t rush the initial 10-minute steam with the lid on. This process softens the cauliflower and draws out its nutty sweetness, preventing a watery tasting soup.
- Consistent Florets: Chop the cauliflower into uniform sizes so they cook evenly. Use the stalk—it has tons of flavor—but chop it smaller than the florets as it is tougher.
- Texture Choice: For a rustic texture, reserve a few small cooked florets before blending and stir them back in at the end. For elegance, blend it completely smooth.
- Topping Idea: Mary often suggests serving this with small cheese savory biscuits or a sprinkle of paprika for color.
What To Serve With Cauliflower Soup
- Crusty Baguette: Essential for dipping into the creamy liquid.
- Crispy Bacon: Salty lardons scattered on top add a savory crunch.
- Cheese Straws: A puff pastry cheese twist is a classic accompaniment.
- Chives: Freshly snipped chives add a mild onion bite and visual appeal.

How To Store Cauliflower Soup
- Refrigerate: Store in an airtight container in the fridge for up to 3 days. It thickens when cold.
- Reheat: Warm gently on the stovetop. Whisk in a splash of milk or water if it has become too thick.
- Freeze: This soup freezes well for up to 3 months. Thaw overnight in the fridge. Note that the texture may separate slightly but will come back together when whisked and heated.

FAQs
Yes. You can skip the “sweating” stage and just simmer the frozen cauliflower in the stock and milk, though fresh cauliflower yields a better depth of flavor.
No, because it uses wheat flour for thickening. To make it gluten-free, substitute the flour with cornstarch (mixed with cold water) added at the end, or use a gluten-free flour blend for the roux.
While this recipe uses a boiled/simmered method for a pale, delicate soup, roasting the cauliflower first adds a darker color and a nutty, caramelized flavor that is delicious but different from the classic recipe.
