prepare vegetables for roasting. to do this, peel and dice the squash if you have not already done so, and peel and chop the carrots into approximately the same size pieces, toss with salt, pepper and a small amount of vegetable oil until evenly coated, then place into a 180°C oven for 40 minutes, turning them over halfway
while vegetables are cooking, dice onions and fry them until just starting to turn brown, before adding them to your intended soup pot. then add the vegetable stock, cover and bring to a simmer
using the remaining oil in the pan, toast off the spices for approximately 30 seconds or until fragrant, and add to your soup pot
take the carrots and squash out of the oven, place the pieces into your soup pot and let simmer until pieces are soft and beginning to fall apart, approximately 20 minutes, though depending on the size of the pieces prior to baking, this may take a shorter amount of time.
taste soup for seasoning before running through a high powered blender or using a handheld blender to reach the desired consistency
