Baked Sweet Potato Cauliflower Soup

Thanksgiving was so great. I luxuriated in a long weekend off work filled with quality family time, catch ups with old friends, and a lot of food.

Not only did we sit down to the usual Thanksgiving feast (prepared by yours truly #humblebrag #girlwithherhandoutemoji), but we also frequented all of our family favorite restaurants, the first of which being Barnaby’s.

Barnaby’s is most known for its classic sandwiches, addictive fries, and colossal salads. And if you get really lucky, you’ll find yourself there on Baked Potato Soup night. My little sister came home from college early and surprised my parents with her presence last Monday night at Barnaby’s, and Barnaby’s surprised us back with an unexpected Baked Potato Soup appearance.

After I stole a few ultra-rich, over the top creamy bites from my sister, I started brainstorming ways I could recreate the cozy, soupy experience at home in a healthier way.

After a few simple swaps– sweet potato + frozen cauliflower in for white potatoes; chicken broth + cashew milk + a smidge of butter in for heavy cream & a LOT of butter– and all the usual toppings (come on, a girl’s gotta live), we were in business. Ready? Lezgo.
