Pre-heat your oven to 180℃
Roughly chop your vegetables and add them to a large roasting pan along with your garlic cloves. I leave the skin on the sweet potato but you can peel it if you prefer!
Add a healthy drizzle of extra-virgin olive oil, ensuring all your vegetables are evenly coated
Season with salt, pepper, smoked paprika and mixed herbs
Cook for 40-45 minutes
Once roasted, transfer your vegetables to a blender. Add the harissa paste, basil leaves and creme fraiche (or cream). Blend until smooth
Transfer your soup to a large saucepan. Add your stock (as much or as little as you like depending on how thick you like your soup). Cook on the hob until heated through
Serve your soup with an extra drizzle of creme fraiche, chilli flakes and black pepper. Enjoy!
