Roasted Cauliflower Soup Recipe
This delicious roasted cauliflower soup is packed full of roasted vegetables. It’s creamy but healthy, made without any cream! The perfect comfort food to warm you up on a cold winter evening.
I am not a huge fan of the cold (I may live in Tucson, but during most of December and January, I wear secret pants to stay warm). My favorite thing about cold days is that it gives me an excuse to curl up under a blanket and eat soup. (You don’t eat your soup under a blanket? Weird.). Now, don’t get me wrong, soup can be good on warm days too. However, there’s something about a steaming hot bowl of soup on a chilly day that just warms my soul.

Thick and hearty
I like all kinds of soup (barring all spicy varieties), but my favorite soups? They have to pass the bread bowl test. If you were to give me a list of soups to choose from, I would always pick the thick, hearty soups that could be served in a bread bowl (and not soak through and disintegrate the bread). Usually, that would involve soups like loaded baked potato, broccoli cheese, or tomato bisque. But, if you will also notice, most of those soups involve cheese or cream and they tend to be a bit heavy on the calories.
So, I avoided both the cheese and the cream. Yet I still ended up with a thick, creamy soup that also happens to consist mostly of vegetables. This roasted cauliflower soup tastes as if it’s full of calories, but isn’t!
I love it when I can eat healthy without feeling like I’m eating healthy.
Kind of like the gummy multivitamin that I take every morning. It gives me an excuse to eat candy with breakfast.
I’ve made many cauliflower soups before. However, the secret to making this one so flavorful is roasting the cauliflower first. It gives it just a touch of sweetness by caramelizing the sugars in the vegetable and really intensifies the flavor.
Blending cooked cauliflower makes for a fairly thick and creamy soup already. But I add Greek yogurt to not only make it even creamier. As an added benefit, it bumps up the protein, which is always a major bonus.
I was so glad I’d made a batch of this early on in the week. Just when I thought we were done with the cool and rainy days, the clouds came back and I had my blanket and leftover soup at the ready.

A must-try on my list. Need to get the yogurt and garlic. Thanks for being there for us! Have a blessed day, “bride-to-be!”
You are so welcome, Patty! I hope you like this recipe as much as I do! Thank you so much for your sweet words. I hope you have a beautiful weekend!
Thank you for this recipe. I have made it quite a few times. Just to change it up on occasion I do roast a few carrots with the cauliflower and it gives the soup a nice rich color.
I’m so glad you enjoy it, Kathy! What a great idea to add roasted carrots, as well. I will definitely have to try that as it gets closer to soup season. Thanks so much for your comment!
First – Yum! Second – gummy vitamins for the win!!!
Oh yum, this looks great! The yogurt is such a smart idea. Also: roasting the cauliflower. You can’t beat it! 🙂
