This roast cauliflower soup is made zingy and bright with the addition of preserved lemon and given an umami hit with miso. This is the perfect warming soup for winter.
You can't get better than a bowl of soup sometimes 🥣
This is such a good January detox soup. Not that I even really believe in the whole detox/new year new you nonsense but after a month of heavy eating and drinking I was so ready for going back to something resembling a vegetable this past week.
I have to be completely honest here and admit that this soup was 100% Will's creation. He took it upon himself to make me lunch and came up with this concoction and it turned out to be completely delicious.
I was slightly apprehensive about the combination, especially the addition of preserved lemon which definitely needs to be used with caution to avoid it overwhelming everything. Everything actually works so well together though and it takes cauliflower soup from something a bit dull to something really special.
Why we love this recipe...
We love that this is a vegetarian soup recipe so it's great for when you're cutting down on meat. You can even leave out the butter to make the whole thing vegan.
It's such an easy recipe to make and most of it is hands off time so you can get on with something else while it's cooking.
While the cauliflower works perfectly on its own in this soup you could add extra veggies if you want to to make it even healthier.
This is a really healthy recipe while still packed with flavour thanks to the miso and preserved lemon.

Cauliflower: This is cut up and roasted until beginning to brown.
Herbs: Rosemary and bay leaf are added to the soup as it simmers.
Preserved Lemon: Just half a preserved lemon is finely chopped and added to the soup for a big hit of freshness.
Stock: Store bought or homemade stock is fine. If you're not worried about it being vegetarian then chicken stock is really tasty.
White Miso: This adds a lovely umami saltiness to balance out the freshness.
