This roasted cauliflower soup with roasted garlic and spinach is packed full of nutrients, and is a healthy low carb entree to keep you warm and satisfied.
Cauliflower is huge in the low carb world, because it has the starchy quality of a potato, but it only contains about 29 carbs for the entire head, vs 37 carbs for an average potato. So while we are trying to eat more healthy, I made this roasted cauliflower soup with roasted garlic and baby spinach.
Roasting cauliflower gives it a nice nutty flavor. All you have to do is clean and cut it up. It's always a good idea to try to make your pieces uniform so that they cook equally in the oven. Throw in a head of garlic drizzled with EVOO and wrap it in aluminum foil. While a head of garlic may seem like a lot, the roasted flavor is much milder than fresh garlic, and remember that it's going in a large pot of soup.
Adding baby spinach gives this dish a boost of vitamins and nice color. Did you know that spinach is high in protein? While I like the flavor of spinach, it really doesn't have a strong presence in this soup but it adds a ton of nutrients.

This looks so good! I have a cauliflower soup recipe I make that I love. I hadn't thought of adding spinach...I think it would really add some good flavor. I'll be saving this to try.

Hi Jenny,
I think there's a good chance that you'll love the spinach addition if you already love cauliflower soup. I hope you get a chance to try it.
