Behold, the ULTIMATE Green Bean Casserole recipe! Featured in magazines across the web and consistently rated THE best green bean casserole recipe EVER, this will convert even the most determined green bean haters! Tender green beans, bacon, cheese, cream, mushrooms and more, this deluxe green bean casserole is made from scratch and is guaranteed to become your go-to from now on!
Green Bean Casserole: The quintessential American side dish for family gatherings, holidays, church socials, potlucks…the recipe clipping that virtually every American woman has had lying somewhere at some point throughout the past gazillion decades. Only this one is different. This one’s the best.  Ever. And it’s made from scratch.
If up until now you’ve just been kind of “meh” towards green bean casserole, prepare to experience a major paradigm shift in attitude. Â This isn’t your Aunt Betsy’s green bean casserole recipe.
I developed this recipe years ago when I had about two pounds of fresh organic green beans and some fresh mushrooms that I needed to use up. As I browsed through my fridge I also noticed some thawed bacon, a block of white cheddar, and some half-and-half cream. The wheels started turning as the blueprint for the ultimate green bean casserole recipe unfolded in my mind. And the rest is history.
This ultimate, from scratch green bean casserole has since become one our most popular recipes every Thanksgiving and Christmas. Multiple websites have praised it and online magazines have linked to it. But most importantly of all, year after year our readers have fallen in love with it. Just read all the rave comments below. Without exaggeration this green bean casserole has literally become world famous. Yes, it’s THAT good!
Even passionate green bean and green bean casserole haters have consistently been converted through this recipe. My brother included. My brother has hated green beans ever since he was old enough to say the word. And he has never once relented. But…he ate this.  He ate THIS!  He ate it…and he liked it!  And as far as I’m concerned that seals the deal. Verdict drawn. Yes. The ULTIMATE Green Bean Casserole.
This recipe take a little longer than the 2 minutes and 38 seconds required to open a can of condensed mushroom soup, mix it with water, toss it with green beans, dump the mixture into a casserole dish, sprinkle with French fried onions, and put it in the oven to bake (ie, the classic recipe first introduced by Campbell’s in 1955). Â But this Ultimate Green Bean Casserole is still quick to make and to say that there is no comparison between the two is the understatement of the century. Â This isn’t called “ultimate” for no reason and we’re confident you’re going to love it as much as we and thousands of others do!
How to Make Gluten Free Green Bean Casserole
You can substitute gluten free flour for thickening the sauce. Alternatively you can dissolve 1 1/2 tablespoons of cornstarch in the chicken stock and then proceed with melting the butter, then adding the half and half and chicken stock/cornstarch, and whisking continually as it simmers until it’s thickened. For the onions you can use gluten free French fried onions.
Can You Freeze This?
We do not recommend it. Creamy sauces have a tendency to break and separate when they’re frozen and thawed and the last thing you want is a watery mess at your dinner table.
Can Green Bean Casserole Be Made Ahead of Time?
Yes! Prep everything and place it in the casserole dish, except for the French fried onions, cover and refrigerate for up to a day before you’re ready to serve it. When you’re ready to bake it, take it out of the fridge and let it sit at room temperature for about 30 minutes. Then sprinkle on the French fried onions and proceed with baking.
This also makes it convenient to bring the assembled casserole (minus the French fried onions) to another location where you’ll be having dinner and then simply add the onions and bake the casserole once you arrive.
Green Bean Casserole Recipe
This recipe begins by frying up bacon along with onions, mushrooms, and garlic. Next we make a roux with butter and flour which will not only serve as a thickener for the cream sauce but will add wonderful depth of flavor. Next we pour in the cream followed by that glorious white cheddar and watch it melt into a rich, luxuriously delicious sauce. Fresh green beans are then folded in the sauce, the mixture is poured into a casserole dish and topped with crispy, crunchy, utterly irresistible French fried onions. It’s baked until bubbly and oozing and then served at the table where it will completely disappear, every last drop of it, within minutes.
Let’s get started!
Fry the bacon in a large skillet over medium-high heat until crispy.
Add the onions and cook for 4-5 minutes until soft and translucent.
Add the mushrooms and garlic and cook for 4-5 minutes until the mushrooms are soft. Â Transfer the bacon/mushroom mixture to a bowl and set aside.
Melt the butter in the same skillet, add the flour, and whisk until combined.
Continue whisking for another minute until the mixture has slightly deepened in color. This will add flavor and cook off the “flour” flavor.
Whisk in the half-and-half and chicken stock and continue to whisk, letting the mixture simmer, until it has slightly thickened.
Whisk in the white cheddar cheese until combined. Add the bacon/mushroom mixture and stir to combine.
Add the salt and pepper. Let the sauce simmer for a couple of minutes, stirring frequently.
Add the blanched green beans and stir to thoroughly combine.
Pour the bean mixture into a 9×13 inch casserole dish.
Sprinkle all of the French fried onions evenly over the casserole.
NOTE:Â Since everything but the French fried onions that go on top is made from scratch, choose some quality ones and avoid using those nasty hydrogenated-oil-packed French fried onions (of course you also have the option of making them yourself!). There are better options out there. Â I had two in my pantry to choose from. Â I went with Lars’ Crispy Onions this time (the 3-pack is the best deal).
Bake, uncovered, for 30 minutes in an oven preheated to 350 degrees F.
Let the casserole sit for about 5 minutes before serving.
ENJOY!

Wendy Fulton says
Hi! When you order the 3-pack of Lars onions, do you use just one of the three on the casserole. Each container is 4oz. The recipe doesn’t say exactly how many ounces to use on the casserole.
Kimberly @ The Daring Gourmet says
Hi Wendy, great question. How much you use just comes down to personal preference. Personally, I love the French fried onions so I tend to be generous but one 4 ounce container is enough to provide an even layer over the casserole.
Cynthia says
Fantastic..made this for a dinner party, I got rave reviews…I gave to credit to The Daring Gourmet…Thank-you for a great receipe!
Kimberly @ The Daring Gourmet says
I’m thrilled to hear that, Cynthia, thanks so much!
Mary Ann Duni says
I’ve been cooking and baking for more years than most of you were even a twinkle in your Dad’s eye (LOL). I just have to say this recipe is absolutely perfect. I only substituted Asiago cheese for white cheddar (family preference) and added a tiny pinch of cayenne and red pepper flakes (again family preferences). Plus it easily converted to a Gluten-Free one…a BIG plus for me. Oh Wow! This recipe literally took me back to my Grandmother’s kitchen. Can’t thank you enough Kimberly for a wonderful memory and recipe. xxxooo
Kimberly @ The Daring Gourmet says
Oh I am so glad, Mary, and really appreciate your experienced vote of approval, thank you!
Audra M. says
“Ultimate” is right, this is the best green bean casserole ever! Making it this weekend for Easter, my third year in a row :)
Kimberly @ The Daring Gourmet says
I’m so glad to hear that, Audra, thank you! :)
MelissaZ says
With Easter around the corner, I’m always in charge of green bean casserole and tired of the same old traditional recipes, but with a room FULL of picky eaters can I change the fresh or frozen to canned? My family doesn’t like crunchy beans as funny as it sounds and they also don’t do mushrooms or chunks of onions can I substitute with onion flakes?
Kimberly @ The Daring Gourmet says
Hi Melissa, sure you can use canned beans and onion flakes will probably be okay, too.
Kate H. says
PHENOMENAL!!!!! That’s the best word I can think of to describe this. Truly the BEST green bean casserole in the world!!
Kimberly @ The Daring Gourmet says
Fantastic, Kate, thanks so much!
Tammy says

Daniel says
I can’t possibly rate this recipe highly enough, it deserves an A++++++!!!!!
Cynthia Allen says
A total smash hit as always, thank you! <3
Jennifer Martin says
Kimberly, i was in charge of the green bean casserole last Thanksgiving and growing up with a family of cooks, I wanted to do something special. I searched and searched and finally came across yours and I hoped this would be my ticket to “wow” my family at the holiday dinner. With limited cooking experience, I took my time prepping and making your recipe (probably 2 hours just making sure I didn’t mess up). While I was cooking it, all I could think about was how it was the most beautiful dish on the planet. When I showed up to Thanksgiving, I felt so proud I had made something spectacular. As I waited for everyone to try your dish I had made, the faces and comments were not disappointing! The upside and downside is that now, three times a year, I am asked “Jennifer, you will bring that green bean casserole as your dish, right?”
To other readers, the Lars Crispy Onions are a little more expensive, but absolutely worth it; I would never use any other kind again.
Going into my 4th time making this. I wanted to make sure I thanked you!
What inspired you to come up with this?
Kimberly @ The Daring Gourmet says
You’ve made my day, Jennifer, thank you! The inspiration? I’ve never been a fan of the typical condensed cream of mushroom soup green bean casseroles and wanted to not only develop one from scratch but bump it up several flavor notches – thus the “ultimate” green bean casserole was born :) I’m so glad it’s been such a hit in your family, thank you!
Cathy nordhues says
Can you make this in a slow cooker?
Becca says
The best green bean casserole in the world!!!!! And I sincerely meant that. I’ve been making this the past two years and it’s always a HUGE hit!
Chelsea says
Could I leave out the bacon or cheese? Have you heard of this making a difference? I’m not a big fan of bacon outside of breakfast ( I know I’m probably the only one) and already have a few cheesy dishes planned so I’d like a contrast.
Kimberly @ The Daring Gourmet says
Hi Chelsea, the bacon and cheese are what really make this dish extra amazing. If you’re worried about this clashing with your other cheese-based dishes, it won’t – I wouldn’t consider this a “cheesy” dish as the cheese melts into the sauce for flavor without being remotely gooey. But yes, if you prefer you can certainly leave out the bacon and cheese.
Chelsea says
Ok… I will give it a shot. This a favorite of mine, but I like the idea of kicking it up a notch.
Katie says
i will be making this for xmas and am very excited, i was wondering if there is s difference in using white cheddar or sharp white cheddar, and which did you use? thank you!
Kimberly @ The Daring Gourmet says
Hi Katie, you can use either, it just comes down to personal preference. If you prefer eating mild cheese go with mild; if you like sharp cheese you can go with sharp. I’ve used both and it tastes awesome either way.
Kimberly Monfort says
I made this delicious dish for Thanksgiving dinner this year. Hands down, it was the most delicious green been casserole any of us ever had! Our family is gluten free and casein free as well, so I used gf flour and dairy free cream. I subbed 1:1 as I followed the recipe. It worked beautifully. This recipe is a keeper!!
Kimberly @ The Daring Gourmet says
Awesome, Kimberly, I’m so glad, thank you!
