Instructions
Soup
In a large pot on medium-high heat, saute the sliced leek in butter or oil until soft, about 8 minutes. Add garlic and cook until fragrant.
Add cauliflower, salt and pepper, nutmeg, herbs, and broth and give it a good stir. Bring to a boil, cover, and turn down to a simmer for 20 minutes or until cauliflower is fork tender. Allow soup to cool until lukewarm before blending.
Use a hand-held immersion blender to blend the soup in the pot until smooth and creamy. Be careful when using a handheld blender in a bot of hot liquid. Alternatively, transfer to a blender and blend until smooth. Add more water or broth until desired consistency is reached.
Crispy Green Onions
In a small saucepan on medium-low heat, heat oil and add chopped green onions. Saute until lightly golden brown and crispy.
Serve soup in a bread bowl or with crusty bread, and top with crispy green onions, a swirl of creme fraiche, or coconut cream- if desired. Enjoy hot!
Notes
Clean Your Leeks: Leeks can trap dirt between layers. Slice first, then rinse thoroughly in a bowl of water to remove all grit.
Blending the Soup: Let the soup cool slightly before blending to prevent burns. An immersion blender is the easiest option!
Prep the Cauliflower: Chop the cauliflower into even, small pieces for faster, more even cooking. Large florets may need extra time.
