Chilly Weather – Caramelized Onion, Fennel & Mushroom Soup

One of the joys of entering a new season is breaking out our favorite recipes for said season. For Fall, that list includes soups & sandwiches for weekend lunches or light dinners. As I posted a new grilled cheese recipe on Tuesday, today is, you guessed it, a new soup! This soup could be considered a vegan version of French Onion Soup.  The addition of fennel adds both flavor and a touch of sweetness. Mushrooms (in both of this week’s recipes) add depth and a savory umami component to recipes.

While mushrooms have been used as medicine and food since the time of the Ancient Egyptians, it wasn’t until the early 1700s that the edible fungi were successfully cultivated in France. It took another century for the practice to spread to the United States. Of the estimated 10,000 species of ‘shrooms in North America, only about 250 are known to be edible. White button, cremini, and portabello mushrooms are all the same mushroom, they are just at different levels of maturity. They comprise ninety percent of the mushrooms bought in the US. And most of what we cook with in our home.

P.S. If you like French Onion Soup, and don’t need a vegan version, this Alsatian Onion Soup is far better!

Add fennel fronds for garnish & a touch of color!

Ward off the chilly weather with some great soup!  ~Linda
