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
Although it’s a star in our Dairy-Free Thanksgiving Menu, 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.
Special Diet Notes: Dairy-Free Green Bean Casserole
By ingredients, this recipe is dairy-free / non-dairy, egg-free, nut-free, peanut-free, vegan, and vegetarian.
- For gluten-free, dairy-free green bean casserole, use gluten-free tamari in place of the soy sauce and you can make your own gluten-free fried onions.

- In a medium bowl, whisk together the condensed soup, milk beverage, soy sauce, and pepper. Add the green beans and half (2/3 cup) of the fried onions, and stir to coat.

This recipe is amazing! I made it last year for my lactose-intolerant boyfriend. This year, the family requested it as the only green bean casserole!
That’s wonderful! Happy Thanksgiving Katelyn!
What type of milk beverage do you use for this? I have almond, oat, and coconut milk.
It’s really a matter of personal choice. I like to use unsweetened coconut milk beverage (like So Delicious or generic) because it’s richest, and I feel that it doesn’t have a strong flavor. I don’t like almond milk in savory sauces, but a lot of people do. I’m just not a fan of oat milk, and most varieties are a little sweet, which I don’t like in savory dishes. But I do know that some people use almond milk or oat milk with this recipe! I personally just avoid any sweetness with savory recipes like this one.
Trying to make into a finger food-like option. Has anyone tried this? Maybe using the French fried onions as a crust in muffins cups? Thx for any suggestions =)
That sounds adventurous! Love the fried onions cup idea, but haven’t tried it. You might want to use french-style green beans since they’re thinner and I think would work better in smaller portions than chunky green beans.
How long would it be good for since the cream of mushroom is only good for 2 days in the fridge? Or would it be the same only 2 days in the fridge?
It keeps as well as a traditional green bean casserole would. Just as a general rule, you’re not supposed to keep prepared leftovers for more than two days, and this recipe doesn’t have any preservatives. So I wouldn’t recommend any homemade dish without any type of preservative (ie lemon juice) be kept more than a couple days, but many people do keep them longer.
What is a pounce? Pound? Ounce?
Pounds, haha! I must have edited from ounces. You definitely don’t want to use just an ounce of green beans 🙂
