Preheat oven to 180C/350F.
Into a baking tray, add in the sweet potatoes, red bell pepper/capsicum, onion, carrot and garlic and spread them into a single layer. Drizzle over generously with olive oil and season well with salt and pepper. Bake for 45min to 1 hour.
Once the veggies are slightly cooled, squeeze out the garlic and transfer the roasted vegetables into a blender with basil, stock and smoked paprika. Blend well until smooth. Add in the heavy cream/coconut cream if desired. Season, top with sesame seeds and parsley, and serve with toasted bread.
