About this recipe: So easy, especially since the slow cooker does all the work! This is a lovely, comforting soup to come home to on a blustery evening.
You don't have caramelise the onions, you can simply melt the butter in your slow cooker, add the onions to coat them and then add all the ingredients and cook. However, caramelising the onions makes for a much, much better soup.
used white wine instead of sherry as thats all i had smells great hopefully will taste great too - 16 Apr 2013
Used English onions and red wine instead of sherry (someone had drunk the sherry) ! It tasted divine, just like a posh restaurants. I will definitely make it again without a doubt. - 02 Feb 2013
