ULTIMATE BEAN GREEN CASSEROLE. 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! We promise!
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. 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). 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. 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!
Can I Make Gluten Free Green Bean Casserole?
Yes! 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 Green Bean Casserole?
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.
The Ultimate 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. 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: 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. I had two in my pantry to choose from. 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!

My first try is in the oven but from tasting along the way, I am sure this will be my go-to recipe forever!
I deviated from the recipe a bit and likely used too much butter for the roux but added extra flour, cream and chicken broth since I was making two packages of green beans. As a result, I decided not to add any cheese but will try it next time I make this. I also used panko bread crumbs instead of fried onions. I also added fresh parsley and ground sage as I find they highlight the mushroom umami nicely.
I’d only add a note to include the parboiling of fresh green beans in salt water in the recipe. Otherwise, awesome recipe! Thanks so much!!
Vicki says
I don’t usually write comments on websites, but I have made this recipe for the past four years and it has been a hit every year (I know I look forward to eating it every Thanksgiving:)). Thank you for this delicious dish! It’s fresh, creamy, and full of those warm savory flavors that everyone enjoys.
I follow this recipe exactly, except for the salt. I found that adding 3/4 tsp. of salt is a bit too salty, but 1/4tsp per recipe (or a little less) is perfect.
Thank you again and have a very happy Thanksgiving with your familiy!
Kimberly Killebrew says
Thank you so much, Vicky, I’m absolutely thrilled that this recipe has become a tradition in your home! <3
Jamie says
This is the 4th year I’ve been making this for thanksgiving. It is the ABSOLUTE BEST!! My family looks forward to it every year. ❤️
Kimberly Killebrew says
So awesome, thank you so much, Jamie! :)
Jean says
If I wanted to use store bought canned beans, how many cans would be needed?
Kimberly Killebrew says
Hi Jean, two 15 ounce cans of beans are roughly the equivalent of one pound of fresh.
Angelina says
My absolute go-to for the last 6 years
Although I’ve been using what I like to call bacon butter ( slow rendered fat from bacon) but essentially the same recipe…
I wish I could find these fatly cut bacon strips though… I’ve gone to the market and asked for thick cut bacon, and it’s just bacon …
Any advice on how to make a request to get the thickness of the bacon right?
Kimberly Killebrew says
That is so awesome, Angelina, thank you very much! :) In the U.S. our bacon options are limited. In the UK for example you can find bacon rashers that truly are thick. It seems that some brands of thick cut bacon are a little thicker than others and it really just comes down to experimenting until you find one you like.
Anonymous says
I use Wright’s thick cut bacon…Sams club…a little speedy but worth it…Walmart should carry too
Mary Jo says
I have a question. How many cans of drained green beans would I use in this recipe? My mom cannot eat fresh ones.
Kimberly Killebrew says
Hi Mary Jo, two 15 ounce cans are roughly the equivalent of a pound of fresh beans.
Tracy Bowser says
By far the best green bean casserole. In fact, I hated green bean casserole until I made this several years ago for Christmas for those that did like it. I decided to try it for myself.It was amazing. I do make it without the mushrooms because I don’t like them.
Kimberly Killebrew says
I’m so thrilled to hear that, Tracy, thank you! :)
debbie says
Has anyone tried using this as a sauce for pasta? I had made this recipe and its amazing but wondering how it would be with pasta?
Kimberly Killebrew says
I think that sounds like a fabulous idea, Debbie! :)
Mrs Behan says
Can I use the same sauce for tuna noodle casserole? I think it might work but not sure…
Kimberly Killebrew says
Absolutely, Mrs. Behan, I think that would be delicious!
Allison Collier says
Love love love, I’ve been making this for yours from your recipe thanksgiving and Christmas! It’s a hit! The only thing I don’t use is the flower, I add two cans of cream of mushroom. Full disclosure, I hate other peoples green bean casserole lol but I love this recipe and so do the kids lol
Patricia L Rose says
Perfect! Exactly what I wanted! I’m not fond of can soups, I use them once in a while but for the holidays I make the sauce myself! I went by the recipe except the onion topping, I crushed the onions up with some crackers and added butter, I love this recipe! It’s a keeper! Thank you!
Eliseus says
THANK YOU KIMBERLY! I’ve been baking this casserole every Holiday season for the past 3 years and I can confirm this dish is enjoyed by ALL who try it… no joke. If you enjoy the old Campbell’s recipe, or green bean casserole in general, then you’ll flip out over this recipe and you owe it to yourself to try it at least once – it will likely not be your last. Here are a couple pointers/tips I’ve learned after making this for years:
CAPACITY – I usually prepare this recipe X3 which will feed a large group. You will need 2 trays, there’s just no way around it, plan accordingly. You’ll also likely run into capacity issues with the skillet when preparing this quantity. As a result, I’ve had to skip the step where you combine the green beans with the rue/sauce and let them simmer together before pouring into baking tray. Instead, I must put the blanched Green Beans in the baking tray and then pour in the rue/sauce, mix and then bake. I’ve tried both adding time to the bake to get all the ingredients to marry or baking as the recipe calls, haven’t received complaints for either.
INGREDIENT DEVIATION – Sometimes Cremini mushrooms are hard to find. I’ve used white button, white button with baby bellas, White Button with baby bellas and Cremini and I’ve done JUST baby bellas. There’s so much going on with this casserole, so many varying depths of flavor that you won’t lose any of the impact with different mushrooms. Sprinkling some shredded sharp cheddar on the top before adding the crispy onions and baking adds a little twist. I’ve also tried 1:1 sharp cheddar with white cheddar to great effect. For beans, I’ve used canned & frenched, regular and haricots vert. No complaints regardless, but my absolute favorite is Frenched haricots verts (julienned French green beans). It takes a little longer to prepare but well worth it.
Bottom line. If you’ve always wanted to have a dish for gatherings that you’re known for – and haven’t found one – give this puppy a try! This casserole will create buzz and everyone will ask if you’re going to bring “your” Green Bean Casserole from now on!
Dollie says
Can mozzarella cheese substitute for White cheddar?
Kimberly @ The Daring Gourmet says
Hi Dollie, you can really use any cheese you like. Mozzarella will just have less flavor and it will have the typical stringy texture that mozzarella has if you don’t mind that in this casserole.
