Cauliflower Leek & Cheddar Soup

We all have most likely heard of potato leek soup…but have you heard of CAULIFLOWER leek and CHEDDAR soup?!?!?! If you have, then…have you ever MADE IT YOURSELF?!?! Well, even if you have, you need to try my recipe because it’s just that good.

Not going to lie, I was surprised when I did a poll on what recipes you guys wanted to kick off Fall (even though it was still 90 degrees outside…) and the majority of you wanted soup. Soup was the last thing I wanted during the hot September (I call it leftover August) transition period, but alas, I made some hot delicious soup. And guys,… you were right. Soup was the move. 

Here’s the thing: if you don’t like onion/garlic/leek things, you won’t like this soup! It’s an allium party with some cauliflower.

Something else I want to note is that this soup can be *thick.* The thickness depends on how much cauliflower you get in your head of cauliflower. If you feel like you have a small head of cauliflower, only use 4 cups of stock. If you have a larger one, have 5 cups prepared. Most boxes of stock come with 4 cups, so to avoid buying 2 and leaving one opened but still full, I recommend using a chicken bouillon and dissolving it into 5 cups of water.

Heat a large stock pot over medium heat. Add the butter. Once the butter melts, adjust the heat to medium high and add the leeks. Season with a generous pinch of kosher salt. Let them cook and sweat for 2-3 minutes, until bright green, slightly caramelized and softened. Add the onion and another pinch of kosher salt. Cook for another 2-3 minutes.

Remove the cauliflower and garlic from the oven. Squeeze the roasted garlic out of the bulb and into the pot. Add the cauliflower, reserving 5-7 small florets for topping.

7.

Pour the chicken stock and lemon juice into the pot. Taste the stock and add another pinch of kosher salt, if necesary for your taste. Place the lid on the pot and simmer for 20 minutes.

Mark as complete
8.

Remove the pot from the heat. Transfer the soup to a blender (if it won't all fit in the blender, do this in two batches.) Blend until smooth. Add the cheddar to the soup and then blend again for about 40 seconds, until creamy.

Mark as complete

Notes

Most boxes of chicken stock come with 4 cups. To avoid buying 2 boxes of chicken stock and not finishing the second one, I prefer to dissolve chicken bouillon into 5 cups of water! You can use vegetable bouillon or chicken.
