👩🏻🍳 Here’s how to make it
Creamy Cauliflower Cheese Soup recipe step-by-step
- Prepare the vegetables: In a large soup pot over medium heat, melt the butter with the olive oil. Add the chopped onion and sweat gently until soft and translucent, about 8–10 minutes. Stir in the minced garlic, cauliflower florets, chopped courgette and carrots and cook a few minutes until everything is coated and beginning to soften.
- Cook the soup: Pour in the vegetable stock, bring to a simmer and cook until the vegetables are tender, about 15–20 minutes.
- Blend and season: Blend the soup until smooth using an immersion or upright blender. Return to the pot and stir in mixed spice, chilli powder, milk and shredded cheddar. Warm gently while whisking until the cheese melts and the soup is homogenous. Thin with additional milk or water if needed, and adjust salt and pepper to taste.
- Prepare toppings: If using pancetta, fry lardons in a small skillet with a little olive oil until crisp, then drain. Tear sourdough into chunks and brown in the rendered fat or in olive oil until crunchy to make croutons.
- Serve: Ladle the soup into bowls, top with crispy pancetta (or roasted chickpeas for a vegetarian option), add the croutons and scatter extra shredded cheddar or herbs if desired.
📖 Variations
- Vegetarian: Skip the pancetta and use roasted chickpeas or toasted nuts as a crunchy topping.
- Dairy-free: Swap milk for a plant-based alternative and use dairy-free cheese or nutritional yeast for a savory finish.
- Adjust heat: Reduce or increase chilli powder to suit your taste.
- Herb swap: Replace thyme with rosemary, sage or dill for a different aromatic profile.
- Cheese choices: Gruyère, Parmesan or a melty vegan cheese all work well for varied flavour notes.
💡 Chef’s Guide: Expert Tips
Simple techniques lift this soup: sweat the aromatics slowly, blend until silky, and add cheese gradually off the heat to avoid graininess.
- Roast the cauliflower for a deeper, caramelized flavour before adding it to the pot.
- Pinch of nutmeg complements the cheese and enriches the creamy notes.
- Infuse the milk with a bay leaf while warming for a subtle, layered aroma—remove the bay before blending.
🍯 Storing and reheating leftovers
- Fridge: Cool and store in an airtight container for up to 4 days.
- Freezer: Freeze in suitable containers for up to 3 months. Thaw overnight in the fridge before reheating.
- Reheat: Warm gently on the stovetop, stirring occasionally. Add a splash of milk or stock if the soup thickens on reheating.
