When the weather is cold, there's nothing quite like a comforting bowl of steaming hot, creamy soup.
Once the cauliflower has roasted this soup can be made in a large saucepan and then blended with a stick blender.
I prefer to use my blender as there's no messing about with extra pots and gadgets, which means there's less to wash up!
If you've never roasted cauliflower before why not?!
Roasting cauliflower gives it a delicious sweetness and tastes so good you'll wonder why you didn't try it before.
The roasting pan I used is a ScanPan which is absolutely the best.
Can I make this soup without a blender?
Yes, you can! If you haven't got a blender you can just cook this in a large saucepan on the stovetop and once cooked, blend with a stick blender.

This sounds delicious, I am going to try it this weekend. I have never tried roasting cauliflower before!
ReplyDeleteTotally agree that roasting is the way forward. Always good to have a new soup recipe at hand.
ReplyDeleteI need need need to roast more cauliflower. Indeed I need to eat more of it in general. We tried to grow some at the allotment but slugs ate all the seedlings! Boo!
ReplyDeleteI LOVE roasted cauliflower! So much flavour. I love the idea of adding the cheese to this soup too, sounds lovely. Think I might make this this weekend, I have cauliflower in the fridge!
ReplyDeleteRoasting cauliflower is a recent concept for me. Why has it taken me so long? Cauliflower cheese soups sounds like a great idea. I couldn't agree more re the 9200A blender - it's fab.
ReplyDeleteWe love cauliflower soup but I have never made it with roasted cauliflower, does it change the taste much???
ReplyDeleteHi Nayna
ReplyDeleteYes it does - roasted cauliflower is sweeter and has a slightly nutty taste, give it a go!
