🔪 How to Make Roasted Cauliflower, Cashew and Tomato Soup
STEP 1 - Roast the Vegetables
Place the cauliflower florets in a bowl, drizzle with olive oil and season with salt and pepper. Toss well, up until all florets are evenly coated in oil, then transfer to a baking tray and bake for 25-30 minutes in a 200°C (400° F) preheated oven. You’ll know cauliflower is cooked to perfection when it turns tender and golden. Roasting intensifies the sweetness and brings out a richer flavour.
STEP 2 - Prepare the Base
Sauté roughly chopped onion and crushed garlic clove(s) in a bit of olive oil and a pinch of salt until onions turn translucent (4-5 minutes on medium heat).
Add the cashew nuts and roast them until golden, stirring constantly to avoiding burning them.
STEP 3 - Simmer and Build Flavour Profile
Pour in the tomato passata and vegetable broth (starting with ½ cup-125g), season with salt, paprika and cayenne pepper, pop the lid on and simmer on medium low heat for 20 minutes.
STEP 4 - Blend the Soup & Enjoy
Once the cauliflower is roasted, transfer the florets to the pot, add nutritional yeast, and blend the soup until smooth with the help of an hand blender. Should the soup result too thick, add more vegetable broth and blend until you're happy with the consistency.
Serve it warm, topped with the remaining roasted cauliflower florets, a grind of black pepper and fresh herbs (dill, parsley and coriander work very well).
