How to Make Cauliflower Leek Soup Step-by-Step

1. Prepare the Veggies
   Slice the leeks and rinse thoroughly to remove any grit. Chop the cauliflower into small florets for even cooking.
2. Sauté Aromatics
   In a large pot, heat olive oil over medium heat. Add the leeks and cook for 6-8 minutes until softened. Stir in the garlic and thyme and cook for another minute until fragrant.
3. Add Cauliflower and Beans
   Add the chopped cauliflower and rinsed cannellini beans to the pot. Stir well to coat with the aromatics.
4. Pour in Broth and Simmer
   Add vegetable broth, ensuring the veggies are mostly covered. Bring to a boil, then reduce heat and simmer for 15–20 minutes until the cauliflower is tender.
5. Blend Until Smooth
   Remove the pot from heat. Use an immersion blender or carefully transfer the soup to a blender in batches. Blend until silky smooth.
6. Season and Brighten
   Return the soup to the pot. Stir in lemon juice, salt, and pepper to taste. Reheat gently if needed before serving.

Extra Tips for the Perfect Soup

• Don’t skip rinsing leeks: They often hide dirt between layers
• Blend in stages: If using a countertop blender, don’t overfill — hot soup can splatter
• Adjust texture: Add more broth if it’s too thick, or simmer uncovered to reduce
• Taste as you go: Add salt and acid gradually for balanced flavor
• Storage: Keeps well in the fridge for 4–5 days, or freeze for up to 3 months

Creative Pairings and Fun Variations

• Toppings: Crispy chickpeas, croutons, or a swirl of coconut cream
• Sides: Pair with crusty bread, garlic toast, or a simple green salad
• Spicy twist: Add red pepper flakes or a dash of smoked paprika
• Herbaceous version: Blend in fresh parsley or basil for a greener take
• Make-ahead: Ideal for batch cooking and freezing in portioned containers
