I love butternut squash soup. Its really simple to make if you have stock prepared.
All you have to do is heat up a duch oven with olive oil, throw diced celery, onion and carrot along with the cubed butternut squash and whatever herbs and spices you like. I also add a few tbsp of brown sugar.
Then after frying for 5 mins, cover it with stock and let it simmer for 40mins. At the end, blend it in a blender or with a hand-blender.
Its like 10mins of active work and you get 2-3 quarts of really healthy soup.
