Roasted cauliflower soup
The perfect roasted cauliflower soup recipe to start Autumn right
As I’m posting this, it is the FIRST OFFICIAL DAY OF AUTUMN! That can only mean it’s S season. Soup season, Slow cooker season and Spiced pumpkin lattes all around! The leaves are turning, the Gimore Gals are out in full force, it’s a great time to be alive.
Now, in honour of soup season, we’re starting off with this beautiful roasted cauliflower soup. We’re not prolonging the cauliflower rice thing, no, we’re using cauliflower how it should be…in a rich and delicious soup. You also can’t beat a good cauliflower cheese – my Christmas version is absolutely ridiculous, in the good kinda way.
Why you’ll be all over this roasted cauliflower soup…
Umami flavours – the white miso paste gives you that unami goodness that balances the dish and gives it a little edge.
Garlic – because when has garlic ever made a dish worth? I’ve suggested 4 cloves, but do your thing.
Double cream – the addition gives you a velvety, rich soup that feels that little bit indulgent.
Roasted cauliflower – the secret to this soup is roasting the cauliflower til golden, giving you an added depth of flavour.
Thyme and bay leaves – my herbs of choice, however you can a little spice too if you like your soups to have a kick.
I’m fully invested in soup season, give me more inspo…
I’m glad you’re here. If like me, you’ve fallen down the soup rabbit hole and crave more and more, then why not try my curried cauliflower soup if you’ve got some spare cauli leftover? We don’t waste any food here, so whip up another batch and stockpile for the next rainy day.
Or, my Thai squash soup blends beautifully aromatic flavours with a load of veg. Perfect to devour ahead of cold and flu season. Trust me, if you deliver this up, fresh and steaming, to any ill relatives or friends, they’ll be forever in your debt.
Now, if you’d prefer a spice free dish, you need to try my French onion soup, inspired by the iconic Julia Child. Don’t forget that the cheesy, delicious toasted topping is non-negotiable.
Cauli at CHRISTMAS
Yes it’s September, no it’s not too early to be thinking about Christmas. Santa gets the elves working year round, so no harm in planning out the most MONSTROUS cauliflower cheese you’ve ever seen. You don’t want your reputation to be tarnished by a sad, watery side dish. Oh no no no, we’re bringing out the big guns for this bad boy. All the cheese, all the garlic, all the drama.
Final thoughts…
If you’re looking for a soup to see you through the autumnal months, that is both luxurious and packed full of veggie goodie, this is the recipe you’ve been waiting for. The swirl of miso makes this soup a little different and will convince even devout veg avoiders that this is a masterpiece. Give it a go and report back.
