This Thanksgiving we wanted to make a classic green bean casserole only, you know, gluten-free and vegan. And we wanted to include those crispy french-fried onions, which are part of what makes it so classic! Guess what! We found gluten-free french fried onions (and they’re organic, to boot! Link below!)

The next thing to deal with was the sauce. The traditional, classic green bean casserole calls for cream of mushroom soup – Campbell’s cream of mushroom soup, to be exact, which is neither gluten-free nor vegan! It’s not surprising, really, that the classic recipe calls specifically for Campbell’s cream of mushroom soup, because green bean casserole was invented by a Campbell’s employee! That’s right, green bean casserole (originally called “green bean bake”) was invented by Campbell’s employee Dorcas Reilly. Here’s what Sheila Miller, Campbell Soup’s test kitchen manager, has to say about her:

Green Bean Casserole was created by a Campbell Soup Company employee, Dorcas Reilly, at our Camden, New Jersey headquarters in 1955. She was one of the first full-time members of Campbell’s Home Economics department—now known as the Campbell Test Kitchen, where I work. Fun fact: Dorcas was my manager at Campbell back when I first joined the company out of college in the late 1980s, and even attended my wedding in 2001!” (Source: Campbell’s Soup website)

Well, guess who already has an awesome, easy gluten-free vegan cream of mushroom soup recipe? That’s right, us! Of course, our cream of mushroom soup recipe isn’t condensed like the stuff you get straight out of the can from Campbell’s, so we had to tinker with it a bit. And tinker we did, and that’s how we came up with our killer classic green bean casserole recipe! Here it is!

Gluten-Free Vegan Classic Green Bean Casserole


3 cups raw cashews
2 cups filtered water
1 small can sliced mushrooms, drained
2 cans green beans, drained, or equivalent cooked fresh green beans
2 teaspoons soy sauce, Braggs aminos, or tamari
1/2 teaspoon pepper
1 1/3 cups gluten-free vegan french fried onions

Here’s a picture of the organic, vegan, gluten-free french fried onions, you can get them on Amazon here.

Preheat oven to 350°.

Put the cashews and water in a high-speed blender and blend on high for 3 minutes, or until creamy. If you don’t have a high-speed blender such as a Vitamix or Ninja, then you may want to presoak the cashews for an hour or more.

Reserve half of the onions (so 2/3 cup), and then mix the rest of the onions and all of the other ingredients together, and place in a casserole dish.

Bake uncovered for 25 minutes. Remove casserole from oven, and sprinkle the remaining 2/3s cup french fried onions on top of the casserole. Return to oven for 5 more minutes. Remove from oven and serve.
