There’s nothing I love more than a warm bowl of soup this time of year. The weather has been cooling down to the 50’s and 60’s and that cool breeze is definitely in the air. We’ve been spending most of our days outside soaking it all in! I find myself adding more soup recipes to my weekly menu and this cauliflower roasted soup is requested often. It is so delicious! Even my two year old loves it.

This roasted cauliflower soup is comforting and one you can feel good about eating. It almost reminds me of a loaded potato soup, but much lighter. It really is so good and you can add in your favorite vegetables.

Cauliflower roasted soup -the perfect comfort food for fall!

This recipe starts out by roasting the cauliflower, carrots and celery with a little olive oil and salt and pepper on top. A lot of times we stop there and serve those veggies as a side dish. While the vegetables are roasting, you’ll start cooking the bacon. Then you’ll make the roux by cooking the onion and garlic in butter and then whisking in the flour.
