What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 1 large head cauliflower cut into florets
- 1 medium yellow onion diced
- 4 cups vegetable broth
- 0.5 cup heavy cream
- 3 tablespoons unsalted butter
- 1 teaspoon ground nutmeg
Step by step instructions
Step 1: Roast the Cauliflower
Preheat your oven to 400 degrees Fahrenheit. Spread the cauliflower florets on a baking sheet, drizzle with a little olive oil, and roast for 20 minutes until they are golden and tender. Roasting adds a deep nutty flavor that sets this soup apart from boiled versions.
Step 2: Saute the Onion
While the cauliflower roasts, melt the butter in a large pot over medium heat. Add the diced onion and cook for about 6 minutes, stirring occasionally, until it is soft and translucent. Season lightly with salt and pepper during this step.
Step 3: Simmer and Blend
Add the roasted cauliflower to the pot along with the vegetable broth. Bring the mixture to a gentle boil, then reduce heat and simmer for 10 minutes. Use an immersion blender to puree the soup until completely smooth and creamy. Stir in the heavy cream and ground nutmeg.
Step 4: Season and Serve
Taste the soup and adjust seasoning with additional salt and pepper as needed. Ladle into bowls and garnish with a swirl of cream, freshly cracked black pepper, and chives or croutons if desired. Serve hot.

Common mistakes to avoid
Watch out for these pitfalls that can affect your results:

- Blending hot soup in a sealed blender without venting which can cause dangerous pressure buildup
