Smoky cauliflower soup with turmeric sweet potatoes and red peppers
This cauliflower soup is the warming equivalent of a great big exotic hug.
Roasting cauliflower until it’s a smoky, caramelised hot mess really makes my day. It’s a simple enough process. You throw some plain old cauliflower in a roasting pan with oil and spices, not really expecting much, but what pops back out of the oven after 30 minutes is a wondrous thing.
Apart from the roasted cauliflower, the cinnamon, cumin, and turmeric work together to bring out the savoury goodness in the vegetables and the sweet potato and red pepper power up the skin-friendly nutrient profile of this lunch or dinner soup.
Turmeric is great at boosting your antioxidant protection against free radicals which is one of the key foundations for heart health, as well as helping with radiant skin, joint, liver and eye health. There are many turmeric supplements available that contain solely the isolate curcumin, but I’m a fan of getting the benefits of a substance in the whole food form whenever possible, so I add turmeric liberally to my cooking.
This soup tastes great on day 1, but it’s even better on day 2, so it makes a perfect packed lunch. I often will double up on this recipe to help prep my lunches for the week.

Recipe Notes
Cilantro and hemp seeds (or pine nuts) also make a nice topping for this and add a bit of protein as well as texture and crunch.
Sounds and looks amazing!
