Ingredients
For the soup
- 450 g (1 lb) cauliflower, cut into florets
- Olive oil, as needed
- A pinch of smoked paprika
- Salt, to taste
- Freshly ground black pepper, to taste
- 5 garlic cloves (whole or crushed)
- 1 leek, finely chopped
- 1 onion, finely chopped

Ingredient Notes
- Cauliflower: Roasting brings out a richer flavor and caramelizes the edges for extra depth.
- White beans: Provide creaminess and protein; canned beans are convenient but rinse to reduce sodium.

- Croutons: Homemade croutons add crunch and aroma; thyme complements the soup well.
Kitchen Tools Needed
- Oven
- Baking tray
- Large pot or deep pan
- Blender or immersion blender
- Knife and chopping board
Step-by-Step Instructions
- Preheat the oven to 200°C (392°F).
- Arrange cauliflower florets on a baking tray, drizzle with olive oil, sprinkle smoked paprika, salt, and pepper. Toss well to coat.
- Roast in the oven for 30–35 minutes until tender and golden, setting aside a small handful for garnish.
- While roasting, finely chop leek and onion.
- Heat a tablespoon of olive oil in a large pot over medium heat. Add leek and sauté 3–4 minutes until soft.
- Add onion and cook another 3–4 minutes until translucent.
- Stir in thyme and chili flakes, frying for about 1 minute to release their flavors.
- Add garlic cloves, cooking for another minute until fragrant.
- Add the cooked white beans and roasted cauliflower (except reserved florets). Pour in vegetable broth or water.
- Simmer gently for 8–10 minutes to meld the flavors.
- Remove whole garlic cloves if used. Blend the soup until completely smooth. Adjust seasoning with salt and pepper.

Pro Tips
- Roast cauliflower with a bit of smoked paprika for a subtle smoky depth.
- Don’t skip frying the spices; it helps unlock their full aroma.
- Blend the soup until silky smooth for the best creamy texture without cream.
- Make croutons ahead and store in an airtight container for up to 2 days.
Lighter Swaps
- Use water instead of vegetable broth for a lighter base, though broth adds more flavor.
- Omit chili flakes to reduce the heat if desired.
- Swap white bread croutons for toasted whole-grain crackers for fewer calories.
Common Mistakes
- Not roasting the cauliflower long enough, which results in bland flavor.
- Overcooking onions until browned rather than softened can alter taste.
- Not blending thoroughly, leaving a gritty texture.
Serving Suggestions
Serve with a simple leafy green salad or a slice of crusty bread for a complete, satisfying meal. The croutons add a nice contrast of crunch against the creamy soup.
Storage Instructions
Store leftovers in an airtight container in the refrigerator for up to 3 days. The soup may thicken; add a splash of broth or water when reheating.
Reheating Tips
Gently reheat the soup on the stove over low heat, stirring occasionally, to maintain its creamy texture without drying out.
