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!

OH MY GOODNESS!! This is the BEST! I was never a fan of the green bean casserole but we had an abundance of beans from our garden this year and needed to do something with them. After trying this recipe, it became my go to!
Thank you so much!
Kimberly @ The Daring Gourmet says
That’s wonderful, Lexie, I’m so glad you enjoyed it, thank you!
Ruth says
Hello! I want to make this for Thanksgiving this year, however I need to leave out the bacon. Any suggestions on a replacement? I don’t eat mushrooms so I will leave those out (or add extra onions) and replace the soup with cream of onion, but I’m not sure how to replace the fat and flavor from the bacon. Oftentimes I can get away with olive oil, but that won’t work in this dish. Thanks in advance for your help. Can’t wait to try it!!!
Alyssa says
I would recommend turkey bacon and extra butter. Make sure to cook the turkey bacon in some butter to pow up the flavor. You could also try sausage if that is an option. I would go for sage sausage if you went that route. Other than that, I’m not sure what else could substitute. I think having no mushrooms would def alter flavor, but my sister is dating a mushroom hater and they just add more chicken flavoring to hide the deficit
Nicole says
Best green bean casserole I’ve ever had! It was the star dish of my entire meal. Usually I see these at holidays with the pans still pretty full but I was almost bummed when I had such few leftovers! A must to have in my saved recipes!
Kimberly @ The Daring Gourmet says
Fantastic, Nicole! I’m so glad it was a smash hit, thanks so much for the feedback!

Since making this GBC last Christmas, my family requested it for Thanksgiving and Christmas again this year. They now expect it every holiday season. My picky husband and picky teen daughter usually have at least 3 helpings of this GBC. Since we typically have ham readily available for our holiday meal, I’ve subbed ham slices for bacon. Thank you for sharing this awesome GBC recipe.
Kimberly @ The Daring Gourmet says
That’s wonderful, I’m so glad your family enjoys this, thank you!
William Moore says
This recipe for green bean casserole looks awesome. That being said, I use chopped Spanish chorizo in my green bean casserole. Don’t use the Mexican chorizo which is like fresh sausage and is very greasy. Spanish chorizo on the other hand is dried and smoked and ready to eat right out of the package. I also try to keep it low carbohydrate, use light cream and fresh mushrooms instead of canned cream of mushroom soup which tends to have added thickeners and is high in carbohydrates and sodium. As for the onions, caramelized onions are better than those dried onion rings used in ordinary green bean casserole. If you like, shredded or grated Parmesan cheese on the top.
Jennifer Owen says
I made this for Thanksgiving and it was so well received that I got asked to make it for Christmas.

Wonderful, Jennifer, thank you so much for the feedback!

Gabi says
Kim, your green bean casserole is a crowd pleaser. I’ve finally found my favorite recipe!
Kimberly @ The Daring Gourmet says
Fantastic, Gabi, thank you! :)
Patty says
Can you use canned green beans? Or frozen?
Kimberly @ The Daring Gourmet says
Hi Patty, you can use either. Here’s what one of our readers recently recommended if using frozen: “If fresh green beans sell out, get about 25% more of the weight in frozen beans, and steam them in the bag half of what is instructed, then throw into the ice bath.”
Kim says
This is a game changer! I just made this for our family Thanksgiving and EVERYONE loved it. My father n law does not eat green bean casserole, but agreed to try mine…he had seconds! I did not add mushrooms (only because I’m the only one in my family who will eat them) and I did not blanch the beans, just boiled 1/2-3/4 done. Otherwise I followed as written. I will NEVER make green bean casserole any other way, ever again. Thank you so much!
Kimberly @ The Daring Gourmet says
That SO awesome, Kim, I’m happy that your dad and everyone loved it, thanks so much!
Travis says
I have searched high and low for a green bean casserole that meets and exceeds my wildest casserole dreams and this is it. Most of the recipes I use are sourced from Bon Appetit, Ina Garten and the New York Times, however, I have tried many versions of their GBC over the years and they just didn’t do the trick–this recipe does. I followed the recipe exactly as written, using extremely high quality ingredients, with one exception: I omitted the mushrooms, as I strongly dislike them. Instead, neurotically, I added additional 12 ounces of bacon and onions (yes, I used a scale) to account for the absence of the mushrooms. I also sauteed the onions slowly for a little longer than suggested to caramelize them add an additional depth of flavor. The end result was out-of-this world. If you are looking for a GBC, look no further, because this is absolutely it.
Kimberly @ The Daring Gourmet says
That’s absolutely fantastic, Travis, thanks so much!!
Stephen Gagnepain says
I’m calling it Awesome Sauce, in my recipe book. I made the exactly as posted (except light cream instead of half and half) it was excellent! Then I realizei , with a little extra liquid it would make a great cream of mushroom soup, then i also thought it would be good with Brussels Sprouts sauteed with the onions! …and how would some jalapenos go??? This is gonna be fun!!!
Kimberly @ The Daring Gourmet says
Great ideas, Stephen, those would all be delicious! Thanks so much for the feedback!
Natalie Rusanovsky says
Just made this first time, put in a whole pack of center cut bacon and the dish won over the turkey!!
Kimberly @ The Daring Gourmet says
So awesome, Natalie, thanks so much for the feedback!!
Sherron says
I grew up with the traditional green bean casserole with mushroom soup and canned green beans every Thanksgiving. I hated it so much I have never made it as an adult. I have sautéed green beans with slivered almonds instead. This year I was asked to bring the green bean casserole to a friend’s house for thanksgiving. I couldn’t say no but I just couldn’t bring myself to make that dish. I found this recipe with fresh green beans, mushrooms and bacon – I mean how can you go wrong with bacon? Plus a white sauce instead of cream of mushroom soup. I made a test run and it was quite good so I made this casserole again for Thanksgiving yesterday and it was a big hit even though it wasn’t piping hot. It still had that great fresh flavor and – bacon!
Kimberly @ The Daring Gourmet says
That’s wonderful, Sherron, I’m so glad your courage paid off and that you were able to find a green bean casserole you enjoyed – thanks so much!
Michael says
Awesome recipe. Everyone loves it! I have made it many times and have a few notes.
One or two extra slices of bacon. Center cut, thick cut bacon is the way to go. No maple or pepper flavor.
If fresh green beans sell out, get about 25% more of the weight in frozen beans, and steam them in the bag half of what is instructed, then throw into the ice bath. People wont know the difference and it saves a lot of prep time, especially when making 3x the amount.
Fresh ground nutmeg. Yes.
Make your own crispy onions. Slice them thin on the mandolin and toss them in the oven on a sheet pan 3x over 20 minutes.
A combo of baby bella and white button shrooms makes a big difference.
Kimberly @ The Daring Gourmet says
Fantastic, Michael, thank you, and thanks also for the tips and feedback!

I never did one with bacon or cheese. It turned out perfect.
