Thanksgiving is that one time of year when everyone in the family demands you to serve green beans. Green bean casserole has been an American favorite for the holidays since Campbell’s created their classic recipe in the 1950s. Their version uses condensed cream of mushroom soup, which contains dairy. But our dairy-free green bean casserole uses my dairy-free condensed cream of mushroom soup recipe. Don’t worry, it’s just as easy and every bit as delicious!
Dairy-Free Green Bean Casserole that’s Just Like Campbell’s
This wonderful side actually makes a great anytime dish, and can be prepared at the last minute. The condensed soup takes minutes to whip up, and the casserole is just a throw together that you can toss right in the oven.
And I have two additional options for mushroom lovers and mushroom haters. If your family simply adores buttons, creminis, or even shiitakes, you can saute 8 ounces of sliced mushrooms for a few minutes in a little oil, and stir them in with the green beans. If your family can’t stand mushrooms, omit them! or you can go a different flavor route with dairy-free condensed cream of celery soup.
Fun fact: French’s Fried Onions are dairy-free, soy-free, and vegan. They do contain wheat, which is why I’ve shared a gluten-free option below.
