Pre- and Probiotics: Healthier French Onion Soup Recipe

Try our healthier twist on a classic restaurant favorite. This soup compared to traditional French onion soup has less salt, less fat and a depth of layered flavor that is super delicious.

Onions are prebiotics (any allium veggie that comes from a bulb) that help feed probiotics naturally. Probiotics are the healthy bacteria in our gut, often called the “second brain”, prebiotics are the fertilizer that feeds probiotics.

Not only is this soup delicious, the pre- and probiotics in it help absorb nutrition, get rid of waste, impact health, weight, focus and hormones.
