Vegan Beef Barley Soup

A Beef Barley Soup made entirely out of vegetables! Portobello mushrooms and dried split peas make this soup meatless and grain-free. This soup is a wonderfully flavorful vegan option to the classic Beef Barley soup. 

Vegan Beef Barley Soup

You won’t believe me when I tell you this recipe for Vegan Beef Barley Soup was an entire fluke of something else I was trying to make.

But it was. A total mess up of Food and Wine’s Split Pea Soup with Portobellos.

You see, me in my brilliant thinking, thought if I added vegetable broth and stock to my split pea soup, it would make it more flavorful. Which it definitely did. However, my split pea soup did not have that beautiful green color I expected it to have.

No, instead I had this brown broth of a soup.

Brown. Not green. Two entirely different colors and not the color I was expecting. By the way, wine was not involved in the making of this soup!

Since it still smelled so wonderful, I decided to try it, thinking it would still taste like a split pea soup. Again I was proven wrong. No this did not taste anything like a split pea soup.

The flavors were more reminiscent of a Beef Barley soup, along with the coloring. A rich brown broth with carrots, celery, barley, and beef.

What?? I never added barley or beef!

It’s amazing how much Portobello mushrooms can mimic beef flavors. And the “barley” were the split peas.

A Beef Barley soup made entirely out of vegetables. By mistake.

I love it when my mistakes turn into something so much more than I originally had planned for them. Now, to make this split pea soup I’ve been craving…

This Vegan Beef Barley Soup is 100% vegetables. The “beef” is the portobello mushrooms, while the split peas are the “barley”. It even has that rich brown color that’s so reminiscent of Beef Barley soups. Gluten-free, meat-free, and grain-free.


  • 1 lb. dried green split peas, soaked overnight
