This soup is comfort in a bowl. 🥣 In just about 45 minutes, you’ll have a piping hot bowl of deliciously velvety, flavorful, and healthy soup ready to enjoy. Comfy chair, fuzzy blanket, and a good book optional, but highly recommended.

I absolutely love the creaminess that roasted cauliflower lends to soups. If this weren’t a keto soup recipe, the cauliflower alone would be enough to make it a creamy soup, but on keto, we get to amp up the creaminess with butter and heavy whipping cream. Yum! Add some chicken broth for flavor and top with crumbled bacon for total soup bliss.

  • It’s total comfort food. Yummy!
