This gluten-free green bean casserole tastes like the real deal stuff you remember and loved every Thanksgiving. The homemade fried onions take it to another amazing level and only take a few minutes to make!
Gluten-Free Green Bean Casserole
Green bean casserole has always been one of my all time favorite Thanksgiving day foods. It is as classic as our gluten-free turkey and gluten-free crescent rolls and as delicious too!
I personally love that with this recipe, you don’t have to forfeit those crispy, crunchy fried onions just because you are avoiding gluten.
I recommend making a big batch and saving some for toppings burgers with!
What to serve with green bean casserole
Our creamy gluten-free mashed potatoes and gluten-free gravy are always a hit when served up with this green bean casserole and our apple sausage gluten-free stuffing!
This sugar free pecan pie from All Day I Dream About Food and these simple roasted parsnips from Healthy Seasonal Recipes both look like something worth trying too!
Our gluten-free cinnamon rolls may not be one of our traditional gluten-free Thanksgiving recipes but they sure are great on Christmas morning.
Gluten-Free Cream of Chicken Soup
Most cream of chicken soups are not gluten-free. If you want to buy one from the store, Pacific gluten-free cream of chicken soup is the best option.
If you are wanting to make a batch of homemade gluten-free cream of chicken soup, we have a great recipe that is wonderful in recipes like this and our gluten-free tater tot casserole as well as on its own.

Tips for making your green bean casserole the BEST…
- Don’t use purple onions when making fried onions as they turn out a bit dark and unpleasant looking. Stick with white or yellow.
- Prepare the homemade fried onions up to three days in advance to save yourself time on Thanksgiving. Be sure to let them fully cool before storing them in an airtight container or ziplock bag.
- Use Pacific brand cream of mushroom or chicken soup as it is gluten-free and not too think in consistency.
- Be sure to season both the fried onions batter and the casserole itself with a bit of cracked black pepper. It adds a great depth of flavor!
Fresh or Canned Green Beans?
You may wonder why I use canned green beans instead of fresh. The truth is that I love a classic green bean casserole and the fresh just don’t give it that same flavor that grandma’s did.
What can I say, I am a very nostalgic person. If you like fresh, most certainly feel free to use them.
No matter which you choose, one thing is certain. Everyone will love this dish! I dare you not to eat all those homemade fried onions before you get them into the casserole.

I tried this casserole on thanksgiving and it was super yummy! I loved having the gluten free onion rings on top. Even those who don’t have a sensitivity to gluten loved it!
This looks great! I've actually NEVER had green bean casserole, so I never knew what I was missing, but I think I might give it a go this year! 🙂
