Healthier Green Bean Casserole; Gluten Free, Dairy Free, Soy Free, Nut Free, Egg Free Recipe

It’s a few days before Christmas and I still haven’t made any of the allergen free Christmas cookies that I make every year (a great basic recipe can be found here), I still haven’t posted the Maple Sweetened Cranberry Sauce that I created for Thanksgiving, and I’m just now getting to posting this….luckily, like the original 1950s recipe, this gluten free, dairy free, soy free, nut free Green Bean Casserole recipe has only a few ingredients! Looks yummy huh?

Healthy, GLuten Free, Dairy Free, Soy Free, Nut Free  Green Bean Casserole

I’m constantly experimenting to try and make some of my favorite childhood recipes not only healthier but also gluten free, dairy free, soy free, and nut free. Throughout most of the year it’s fun. Around the holidays, I start to feel a bit overwhelmed.   So many recipes, so little time! So when Aloha’s social media started looking for inspiration for a gluten free, dairy free, soy free, nut free spin on a dish to pass, I decided that I would take this opportunity to FINALLY test out the gluten free, dairy free, soy free, nut free green bean casserole recipe I’ve been dreaming up. Feel free to check out their website for more healthy recipes, here  – take note though that they are not all allergen free so be sure to thoroughly check the ingredients! Also, if you are thinking about using their products be sure to pay close attention to the ingredients. If you can’t have legumes (like me), a lot of their products have peas and also use chick peas (for vitamin k).

Do you know the history of the green bean casserole?  It was created in the mid-50s in the Campbell’s Soup test kitchen (surprise surprise right?) It was basically designed to be any easy side dish that people could make with things they had on hand. I remember it tasting so good, but honestly -it’s my nightmare. Cooking with only things that you have on hand in your pantry? Not the epitome of healthy.  Take a look at the ingredients of Cream of Mushroom soup and you’ll find that only the first two are good for your health:


Like I said, my nightmare! It literally makes me queasy when I read those ingredients! So what’s in my recipe?

Green Bean Casserole; gluten free, dairy free, soy free nut free, corn free recipe

Green Bean Casserole, the Healthy, Gluten Free, Dairy Free, Soy Free, Nut Free Version

makes about 12 servings


2 lbs fresh green beans, trimmed and washed

1 lb sliced mushrooms, washed

2 1/2 large onions

6 tbsp Arrowroot Starch/Flour (or corn starch)

1 tsp black pepper

2 tsp kosher salt + additional for seasoning water

1 carton Imagine Organic Creamy Portobello Mushroom Soup

2 tbsp Coconut Secret Coconut Aminos Soy-Free Seasoning Sauce

3-4 tbsp Sweet White Rice Flour (glutinous rice flour) for thickening – you could use more arrowroot starch or cornstarch but you may have to play with the proportions. I use sweet rice flour because it freezes well)

Avocado Oil (or other high heat cooking oil)


Preheat oven to 450 degrees and get a large pot of water boiling to blanch your green beans. First you’ll need to get the “fried” onions cooking in the oven. In a small bowl, mix arrowroot powder, salt and pepper.  Drizzle avocado oil (or other high heat cooking oil) on 2 baking sheets. Slice your onions into 1/4″ thick slices (be sure you don’t slice too long before you’re going to make this dish. Tried that once, doesn’t work!), toss them in the arrowroot powder to coat, shake off excess, and spread in a single layer on the baking sheets. Bake at 450 degrees for 7 or so minutes, flipping half way through. Once they’re done, turn the oven down to 400 degrees. While they’re baking you can get together everything else…

Making Gluten Free, Dairy Free, Soy Free Fried Onions for Green Bean Casserole

By now the pot of water for the green beans should be boiling. Season the water with about a teaspoon of salt and dump in the green beans. Boil for 10 minutes. In a saute pan, cook mushrooms in a little avocado oil until fully cooked. Drain green beans and place them into your casserole dish. In the same pot you boiled the green beans in, add the carton of Creamy Portabello Soup and bring to a simmer, stir in coconut aminos. In a small bowl, whisk together one ladle of the soup and 3 tbsp of sweet rice flour. Whisk mixture into the pot. Once thickened slightly stir in mushrooms and green beans, gently fold in 1/2 of the “fried” onions. Place into your casserole dish, top with the other 1/2 of your fried onions and bake for 20-25 minutes at 400 degrees. Enjoy!
