This homemade vegan and gluten-free green bean casserole is a simple take on the Thanksgiving classic, making it one everyone can enjoy!
The number one requested Thanksgiving recipe I got was for a dairy-free and gluten-free green bean casserole. I am stoked to say...I did it!! And this recipe was SO MUCH EASIER than I thought it would be!
Many of my recipes are pretty simple. I don't like dealing with complicated recipes, long ingredient lists, or having lots of dishes to wash (I seriously have such a low dish-washing patience threshold). The thing that made me nervous about attempting a vegan and gluten-free green bean casserole free that was also free of the eight most common food allergens was my fear that the recipe would get crazy complicated since everything would be recreated from scratch.
Fortunately, I did it, and in less than ten ingredients at that!! And not trying to toot my own horn or anything, but my husband said this is now one of his absolute favorite NTF recipes.
Vegan, gluten-free green bean casserole recipe notes:
- The sauce is made with any milk substitute of your choice. Rice milk is free of all top eight most common allergens, but you can use whatever you prefer and what suits your needs. Do me a favor though, and make sure whatever milk/ milk substitute you're using is unsweetened and unflavored. 😉
- The sauce is thickened with ground flax seed. You can see the ground flax seed in the sauce, but it's a great natural, fiber-rich way to thicken without using flours that may contain gluten. You can alternatively substitute ground chia seeds, too (white chia seeds will be less noticeable visually).
- Coconut aminos are used in place of more traditional soy sauce. You can certainly use soy sauce if you prefer, but coconut aminos are naturally gluten-free, soy-free and lower in sodium than most traditional soy sauce.
I also would be remiss if I didn't talk about fried onions for a minute.
Gluten-free fried onions: homemade vs. store-bought?
So, full transparency, I totally tried making my own fried onions for a crunchy topping. And they were fine, but in all honesty? Those crunchy fried onions found in a can this time of year still taste best. I saw gluten-free fried onions available at several stores around Thanksgiving, including Aldi where I bought these (they just had a few ingredients and were also vegan, FYI).
If you can't find gluten-free/ allergy-free fried onions, feel free to use this method to make your own: Just slice an onion into half moons, spray with a tiny amount of nonstick spray and toss with ground flax seed and salt. Bake at 400 degrees for 15-20 minutes or until crispy.
