I get lots of recipe questions throughout the year, but never more than in the lead-up to Thanksgiving. One question that comes up often is, “How do I make gluten free onion rings for my Grandma’s Green Bean Casserole??!” And while we’re at it, “How do I make gluten free Green Bean Casserole?!” Or even better: “How do I make gluten free onion rings and green bean casserole gluten free AND dairy free?!”
For heaven’s sake, please don’t give up on favorites like onion rings and green bean casserole at Thanksgiving. I have gluten free and yes, dairy free recipes for all your traditional family recipes like this one, just search my blog and I’ll bet you’ll find it: gluten free pumpkin cheesecake, gluten free pumpkin pie, flaky gluten free pie crust, gluten free cinnamon rolls, gluten free stuffing, gluten free sweet potato casserole, gluten free pecan pie … the list goes on of all the things you CAN make gluten free and even dairy free!
And for other recipes like your grandma’s gravy, just use my gfJules™ Flour in place of regular flour — easy peasy.
So settle in and start searching for all the things you’re going to make this year, starting with this easy recipe for gluten free green bean casserole with homemade onion rings. My version is crispy and light and never greasy because it’s baked! Sound like a winner? It is!
While this gluten free green bean casserole recipe is super simple, feel free to use your favorite family recipe instead. Just sub in my gfJules ™ All Purpose Gluten Free Flour for any flour called for in the recipe and be sure to use only gluten free soups and other ingredients.
It all starts with the homemade gluten free onion rings, and that couldn’t be easier!
Just slice, toss in my gfJules Flour and arrange on a parchment lined cookie sheet.
I like to spray them with oil before sticking them in the oven to enhance the crispness. I’m sure these would also turn out great in an air fryer!
Toss them a couple times while they bake so they don’t burn, but get nice and crispy! Of course, you can always just FRY these the old fashioned way. It’s all up to you!
Then comes the green beans. Fresh is always best, but my mother used to make this casserole with canned beans and no one seemed to care/notice/complain.
I like to add fresh mushrooms, but you can skip these if you’re super mushroom-averse.
The fun part is making the roux! Bet you didn’t think you could do that with gluten free flour, did you?
It thickens up beautifully with my gfJules Flour!
Once all the component parts are ready, you mix them all together (saving some pretty onions for the top, of course) and bake!
And because I know you’re going to ask, this beautiful “gluten free” wood cutting board is from Words With Boards® Combine that with an embossed stainless gluten free serving spoon and you have a dish everyone will know is gluten free (no mixing the spoons and cross-contaminating our beautiful casserole!).

Wishing you and yours a very happy and tasty Gluten Free Thanksgiving!
Gluten Free Onion Rings & Green Bean Casserole
This old fashioned green bean casserole is made new again as a dairy free and gluten free green bean casserole everyone will love! Perfect addition to your gluten free Thanksgiving table!
Ingredients
Green Bean Casserole
- 1 pound green beans, canned or fresh, rinsed, trimmed and halved
- 2 Tbs. unsalted butter or non-dairy substitute (Green Valley Organics® lactose free butter or Earth Balance® Buttery Sticks)
- 2 large portobello mushrooms, sliced (this is to taste -- up to 2 cups diced works, or omit entirely)
- ½ tsp. freshly ground black pepper
- ½ tsp. garlic powder
- ¼ tsp. ground nutmeg
- 1/3 cup dairy or non-dairy sour cream (Follow Your Heart® Vegan Gourmet® Sour Cream)
- 2 Tbs. gfJules ™ All Purpose Gluten Free Flour
- 2 cups cream of mushroom soup (Imagine™ Portobello Mushroom Creamy Soup is gluten-free & vegan)
"Fried" Gluten Free Onion Rings
- 1 medium onion, sliced thinly
- 1/3 cup gfJules ™ All Purpose Gluten Free Flour
- 1/4 tsp. sea salt
- non-stick cooking spray (Winona Pure™ Olive Oil spray)
Instructions
To make the "fried" onions, preheat oven to 375° F. Line a baking sheet with foil and spray well with cooking spray. Set aside.
If your sliced onions aren't very wet, dip in water or milk or spray with oil. Combine the sliced onions and dry ingredients in a large bowl, tossing until totally coated with flour. Transfer onto baking sheet and separate the onion ring slices as much as possible.
Bake for 15-20 minutes, tossing one or two times while cooking to a golden brown.
Remove to cool while making your casserole. If the onions aren't browning enough, broil briefly or toss lightly in oil in a skillet before topping casserole.
Once cooled, break apart into smaller pieces for sprinkling on top of the casserole.
To make the casserole, increase oven temperature to 400° F. If using fresh beans, boil in lightly salted water for 5 minutes, then rinse with cold water and drain. If using canned beans, rinse and set aside.
In a large saucepan, melt the butter and toss in sliced mushrooms and pepper. Stir over medium heat for 5 minutes, then add spices and flour, stirring to coat.
Cook an additional minute then add the sour cream and soup and lower the heat to medium-low.
Cook while the mixture thickens, approximately 5-8 minutes more. Remove from heat and stir in half of the fried onions and all of the drained beans.
Pour mixture into a large casserole and cook for 15 minutes, or until bubbly (+ 15 minutes longer if using fresh beans, or until desired tenderness).
Sprinkle the remaining onions on top and bake for an additional 5 minutes. Serve warm.
Be sure to pin this one for later!
Jules – Can I just use a store bought cream of mushroom soup (like Pacific Foods) or do I need to add the mushrooms, flour, sour cream, etc., to get the recipe to come out like “regular”?
Hi Pam, I use both the soup and the flour, sour cream etc. You can certainly skip the extra mushrooms, but I really like the consistency of the casserole with more than just soup.

I saw Gluten Free Fried Onions for green bean casserole at Aldi’s and our local grocery store, Giant, this week. Those not having luck with the onions can pick up a can and still make green bean casserole.
I love that not only are those onion rings GF but they’re also baked rather than fried!
I wish I had read the comments first before trying. The flour didn’t stick to most of my onion rings despite them being moist (the flour did stick to my fingers lol) and so mine didn’t turn out very well. I wound up throwing the batch away. I’ll try again another time and use the milk trick. Would butter spray (like Pam) work too as an adhesive?
Hi JB – sorry the flour didn’t stick to the onions as well as it did your hands!
You can try anything like water or milk or oil, so spray Pam *(no flour in the Pam!) could help.
If using frozen green beans, would you thaw or blanch them first? This recipe sounds perfect!
Hi Beth – I hope you get to try it! As for the frozen beans, yes, I would recommend thawing them and perhaps even blanching before using them. They would probably be ok just with the thaw, but blanch if you want them to be nice and soft in the casserole. Enjoy!
I make gluten free cream of *** soup for.casseroles with Knorr concentrated broth combined with 1 1/2 C water. Wisk 2 T cornstarch with a small can of evaporated milk. Bring the broth to a boil. Stir in the milk stirring until thickened and smooth.
How does the flour stick to the onion rings? I don’t see any type of liquid adhesive.
Hi WagnerJB, the onions are moist enough to cause the flour to stick, but if you find that they are too dry, you can always wet the rings in milk or water first. Enjoy!
Sorry to bother you…I now read that Imagine Foods has a gluten free, dairy free mushroom soup. Thanks for all your help – this sounds delicious!
Pacific Foods has a wonderful condensed cream of mushroom soup, as well as cream of chicken and cream of celery. Our Target, which has a grocery section, carries it, but I have also found it at Ralph’s (Kroger if you’re on the East Coast). Here’s a link so you can see the box: http://www.pacificfoods.com/our-foods/condensed-soups Works GREAT in green bean casserole!
Fantastic, Rene! Thanks for the info!
No worries, Bobbie! Glad you found it!
Hi Jules – any substitute for cream of mushroom soup? I’m lactose intolerant as well as gluten intolerant. Thanks. B
I am thrilled to find a recipe for gf onion rings! I have missed green bean casserole very much, not just because of no gy onion rings, but because I don’t know how to make gf mushroom soup. Do you have a recipe for gf mushroom soup? I hope I haven’t missed it!
Hi Mary Margaret, I haven’t published a recipe for cream of mushroom soup, so you haven’t missed it! If you search the internet and find one that sounds good though, just use my Jules flour in place of the wheat flour they use for the roux – works great! OR, you could just buy one of the brands I have listed in the intro as gluten-free soups for the casserole. Enjoy the recipe!!!
I was wondering if you have a favorite cream of mushroom soup that you can recommend? Would this be condensed? Thanks for a great sounding recipe, as usual!
Hi Jamie – in the intro, I list 3 good brands to try. You can probably only easily find one or two of those, so grab them when you can and see which you like best! Enjoy!
Thank you! Green bean casserole is always a staple at my family’s thanksgiving dinner but this is my first year being gluten-free
I was afraid I wouldn’t be able to have one of my favorite thanksgiving dishes!
That’s wonderful, Caroline! So glad you’ll be able to have one of your favorite Thanksgiving dishes safely again!
