How to Make Creamy Cauliflower and Leek Soup

Step 1: Sauté the Leeks

Start by melting the butter in a large soup pot over medium heat. Add the sliced leeks, making sure to use only the white and light green parts for the best flavor and gentle color. Sauté the leeks for about 5-6 minutes, stirring occasionally, until they are soft and fragrant without any browning. This step encourages their sweet, mellow flavor—a perfect opening act for our Creamy Cauliflower and Leek Soup.

Step 2: Add Cauliflower and Broth

Once your leeks are nicely softened, toss in the chopped cauliflower. This is where the transformation begins! Pour in the vegetable broth, ensuring the veggies are just covered. Bring everything to a gentle boil, then reduce the heat to a simmer. Let it bubble away uncovered for about 20 minutes, or until the cauliflower is beautifully tender. The aroma at this stage is irresistible and hints at the cozy flavors to come.

Step 3: Blend Until Smooth

Turn off the heat and either use an immersion blender right in the pot or carefully transfer the mixture to a blender in batches. Blitz until completely smooth and creamy—this is what gives Creamy Cauliflower and Leek Soup its signature velvety texture. Take a moment to admire that pillowy smoothness!

Step 4: Stir in Cream and Season

Return your blended soup to the pot if needed, and pour in the heavy cream. Stir to combine, and taste for seasoning, adding salt and pepper to heighten every flavor. Heat gently until everything is warmed through. That swirl of cream not only adds luxury but also beautifully balances the delicate earthiness of the soup.

Step 5: Serve and Enjoy

Ladle into bowls while piping hot, and prepare for compliments! Whether you’re sharing Creamy Cauliflower and Leek Soup with family or treating yourself to a quiet lunch, it shines on any table.

Freezing

This soup freezes like a dream! Just hold back the cream if you plan to freeze—add it after thawing for the best texture. Pour into containers or freezer bags, leaving a bit of space for expansion, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.

Warm leftovers gently in a saucepan over low to medium heat, stirring frequently and adding a splash of broth or water if it seems too thick. If you froze your Creamy Cauliflower and Leek Soup, reheat after thawing, then stir in the cream for a perfectly smooth finish.
