My easy Gluten Free Green Bean Casserole was originally titled “Ermahgerd Green Bean Casserole” because ERMAHGERD this holiday dinner staple is so good I nearly shed a tear after scraping up the last few bites!
Now, canned fried onions and cream of mushroom soup have a lock on traditional Green Bean Casserole, but neither are typically gluten free. Problem solved with this re-imagined, gluten free Thanksgiving side dish recipe with major flavor thanks to…
- Crispy Shallots: the crispy shallots I pan fry to top the green bean casserole are a slightly more sophisticated take on canned onion rings and give each bite a craveable, caramelized-onion flavor and crunch. They’re my favorite part of the whole dish.
- No Condensed Soups: true, there are gluten free condensed soups options at the grocery store nowadays, but to my knowledge none of them are gluten-free AND dairy-free, which is important to many, including my family. My homemade, Gluten-Free Cream of Mushroom Soup calls for fridge and pantry staples like gluten-free flour, and chicken stock, and can be easily made dairy free. It creates the most luscious mushroom sauce!
- Garlic-Butter Mushrooms: while I was GF’ing this recipe I figured I might as well improve upon it so I added sizzling, sauted garlic-butter mushrooms into the mix. Trust me when I tell you this is a MAJOR UPGRADE.
Ingredients Needed
- Homemade Cream of Mushroom Soup: I know, I know – opening up a can of soup sounds easier than making a batch from scratch, but this version takes less than 10 minutes and, like I mentioned, is undeniably delicious. It makes each creamy scoop of green bean casserole absolutely irresistible.
- Butter: To saute the sliced mushrooms in. Feel free to use vegan butter to make this a dairy-free green bean casserole. The butter pairs deliciously with the…
- Garlic: Fresh garlic sizzling in butter will not only permeate your home with the most amazing aroma, but also infuse the…
- Mushrooms: Like I said, I think the addition of sauteed garlic-butter mushrooms REALLY elevates this re-imagined classic! I typically use button mushrooms or baby bella mushrooms.
- Homemade Seasoned Salt: Such an easy way to add lots of flavor, plus it’s made with 4 everyday ingredients.
- Green Beans: I prefer canned green beans in this recipe though you can use fresh green beans if you prefer. I’ll outline the method below.
- Shallots: Topping the homemade gluten free green bean casserole with fried shallot rings is just about as good as it gets in life! They are crispy and once sprinkled with a little salt? OH MY WORD. That said, I have saved time by using canned gluten free french fried onions when I can find them, which are awesome too!
- Extra Virgin Olive Oil: We use EVOO to shallow fry the shallot rings.
Canned vs Fresh Green Beans
Let’s address the elephant in the room – canned green beans. Yep, I’m a fan! While I’ve used fresh green beans for Green Bean Casserole in the past, I have to say my heart is with canned. It’s hard to beat the texture, taste, and convenience.
That said, if you MUST use fresh green beans, you’ll need ~4 cups trimmed and chopped green beans. I recommend blanching them for 5 minutes in a large pot (meaning, boil them for 5 minutes then transfer to an ice bath to stop the cooking process) before baking to ensure they cook all the way through. I personally dislike frozen green beans, and do not recommend them for this recipe.
Whether you have to eat gluten free or not, this easy Green Bean Casserole is not be missed this holiday season. I was not kidding when I talked about tearing up when the last bite was gone. Once you try my gluten-free green bean casserole recipe, you will NEVER make another!
How to Make Gluten Free Green Bean Casserole From Scratch
I’ll share step-by-step photos below for how to make my Gluten Free Green Bean Casserole, but here’s a quick overview:
- Step 1: Saute the garlic butter mushrooms in a large skillet then scoop into a casserole dish.
- Step 2: Make the homemade Gluten Free Cream of Mushroom Soup then add to the casserole dish.
- Step 3: Drain canned green beans then add to the casserole dish.
- Step 4: Add a sprinkle of homemade seasoning salt then stir everything to combine and bake until bubbly.
- Step 5: Pan fry shallot rings then sprinkle on top of the casserole and bake for another 5 minutes before serving.
How to Make This Recipe
Start by melting butter in a large, heavy-bottomed skillet over medium-high heat then add sliced mushrooms. Saute until the mushrooms release their liquid, the liquid cooks off, and the mushrooms turn golden brown, 5-7 minutes. Add minced garlic, season generously with homemade seasoned salt and pepper, then saute until the garlic is very fragrant, 1-2 more minutes.
My homemade seasoned salt adds a TON of flavor to this dish and is beyond easy to make – it’s just a mixture of salt, paprika, onion and garlic powders. I hardly ever use regular salt when cooking! You’ll love it.
Scoop the mushrooms into a medium-sized baking dish, like an 8×8″ or similar, then add canned green beans that have been drained, an extra shake of seasoned salt, plus 1 batch Homemade Cream of Mushroom Soup.
Feel free to make the homemade soup several days in advance. Store in an airtight container in the fridge.
Fold everything together using a spatula then preheat oven to 350 degrees and bake until bubbling, about 30 minutes.
While the beans are cooking, wipe the skillet out with wet paper towels or a dish cloth to remove any bits of garlic that might burn and turn bitter during the shallot frying process. Thinly slice shallots then separate the slices into rings.
Heat extra virgin olive oil in the same large skillet over medium-high heat then, once the oil is hot, add half the shallots and fry until golden brown. I like to gently shake the skillet, and stir every now and again, to make sure they fry evenly.
Scoop the fried shallots onto a paper towel lined plate to drain then sprinkle with salt. Fry/drain/salt the remaining shallots.
Note: some of these fried shallots look soggy but I assure you that even the very light golden brown fried shallots are still crispy – YUM!
Last step is to sprinkle the fried shallots on top of the Green Bean Casserole then bake for 5 more minutes. Let the casserole cool for 10 minutes or so then scoop and serve.
Can I Make the Green Bean Casserole Ahead of Time?
This is a great dish to make ahead of time! Saute the garlic-butter mushrooms, make the Cream of Mushroom Soup, and then stir together with the drained, canned green beans in the casserole dish. Cover then refrigerate for up to two days. Uncover and let the baking dish sit at room temperature for 30 minutes before baking according to recipe instructions.

I made this for thanksgiving and it was delicious! i would even say better than the original green bean casserole dish!I’m planning to make it again for Christmas :)
Green bean casserole is a family favorite and this recipe does not disappoint. It is so tasty. This grandma had the crazy idea of adding diced chicken to it for a complete gluten-free, dairy-free casserole. It was a huge hit. Mr. Picky Eater grandson said the only problem was I should have made two. One for him and one for everyone else!!! On the menu again for tomorrow night. Two this time. :-)
Made this and loved it. Shared it with my group. Thanks for the great recipe!
This is my 2nd Thanksgiving bringing this to the family get-together. My sister-in-law is gluten free, but everyone enjoys it. Thank you, Kristen!
Also, for those of you asking, I have made this ahead. I keep the green bean portion in the fridge overnight and even fry the shallots before I leave home – just bring them along and add at final bake ?
I also hope to make this casserole for Thanksgiving. Seems it is always busy in the kitchen that day. Can I make the fried shallots a few days ahead? Any other suggestions on making this casserole a day or so early
I now have a go-to recipe for green bean casserole; thanks, Kristin! This was way better than the original ( and no weird glop!!).
I’m so glad you loved it, Patrice! Thanks for your feedback!
I made this for Thanksgiving since we have a dairy-free family member and OMG it is SO GOOD. I was worried about liking it since traditional green bean casserole is my fav part of the holiday but it was incredible. And I couldn’t stop eating the cream of mushroom soup that was leftover :) Thank you for creating this!
This was awesome! Rave reviews yesterday at thanksgiving dinner! Thanks for an awesome recipe!
[…] farro and butternut squash. And don’t forget to reserve some crispy fried onions from your green bean casserole. Do you have any combination of leftover squash, or sweet potatoes, cranberries, green beans, […]
If I do use fresh green beans over the canned, how do you suggest preparing them to use in the casserole? Just blanch them prior to putting them in the casserole? Thanks!
I would make sure they’re cooked to your preferred level of doneness first since they won’t soften too much in the oven!
I just made the cream of mushroom soup in preparation for Thanksgiving. OMG- it’s a game changer! I could eat the whole batch myself. I can’t wait to try the finished dish. Question- do you think the fried shallots could be made in advance?
If I don’t like mushrooms and leave them out, should I still add the butter and garlic to create a small amount of sauce or for extra flavor in the dish? Thanks! Been looking for a GF green bean casserole for a couple years now!
Nah, it’ll still be plenty good without it!
I’ve found my people! Team Canned Green Beans all the way.
Yeah girl!
This is my favorite thanksgiving side dish! Thanks so much for sharing this recipe. :)
My pleasure, Kristen! I hope you love it if you get a chance to make it!
I can’t wait to try this, thank you for sharing!! Green bean casserole has been the Thanksgiving item I’ve missed most since I had to go gluten free. So looking forward to having it again this year.
Oh my gosh, so glad to hear you’ll be able to enjoy it again! Hope you love it, Liz!
Hello! Any suggestions for substituting the mushrooms? I love them, but my hubby not so much. :) Thank you for all your awesome recipes!
Totally understand (I used to hate mushrooms too.) ;) You can just leave them out!
Love canned green beans!
Definitely love fresh too but you can’t beat the convenience of canned. ;)
Another fan of canned green beans over fresh. The only time I liked fresh green beans is when my mom put them in with ham and potatoes, so they ended up soft and flavorful.
Mmmm, yes! I love fresh roasted or sauteed with bacon and shallots, but you can’t beat canned in casserole!
Yessssssssss!! I love me some canned green beans…I personally HATE the dry texture and lack of flavor of fresh green beans. Thank you for another awesome recipe.
I hope you love it, Beth!!
We were talking about leaving green bean casserole off our menu this year, but this may revive it. Also, I thought I was the only person in the world that liked canned green beans! I only really like fresh green beans when roasted or cooked low and slow forever.
Oh my gosh, please please try this recipe then! Let me know what you think if you give it a go!
