To me, Thanksgiving dinner isn’t complete without a Green Bean Casserole.  Growing up, green bean casserole was my favorite part of the meal – you know, the old fashioned Campbell’s Casserole made with Cream of Mushroom Soup and French’s Fried Onions.

The problem is that Campbell’s Cream of Mushroom soup has MSG and all kinds of unsavory additives, stabilizers, and fake junk inside. It was a sad day for me when I found this out.  How was I supposed to have Thanksgiving without my beloved, savory Green Bean Casserole?  Over the years, I’ve  tried to come up with solutions and have finally mastered a perfect all-natural version.   Well, a perfect Vegan version because although I do eat limited dairy products, I try to avoid them and substitute whenever possible.

The mushrooms and sweet onion combine with the Portobello mushroom soup to create a delicious, creamy sauce with just the right kick.  The natural French Fried Onions are a must, there is just enough to give the casserole the right crunch and texture but not overwhelm the taste.  An added plus is that this is vegan and pretty low on points without sacrificing any of the comfort-food-holiday-flavor we have all come to love and crave!


  •  This recipe isn’t really difficult, the only element that is time-consuming is the preparation of the string beans.  DO NOT SKIP THIS or try a shortcut.  Cutting the beans in this way allows them to get just the right texture and makes this a casserole, not a dish of green beans with sauce around it.  Trust me, as much as this is a pain in the arse, it is worth it!
  • A must have is Imagine’s Natural Creamy Portobello Mushroom Soup.  I purchased it at Whole Foods but have also seen it at Fred Meyer, Safeway, Wegman’s and in other grocery store’s natural food sections.  Unfortunately, I haven’t seen it at Trader Joe’s.   This Vegan Portobello Mushroom Soup is used as the base for the sauce.
  • French Fried Onions – I don’t have a brand preference but if you live near a Trader Joe’s, buy theirs.  They are relatively inexpensive and the jar is 8 ounces.  Otherwise, just buy them in the natural section of your grocer to avoid the crazy additives. Whole Foods sells Lars Crispy Fried Onions in a 4 ounce container and I have also seen another brand or two there.
  • TIP: To save time, prep your onion, garlic, mushrooms, and green beans the night before or early in the morning.
