What is Green Bean Casserole?
Green Bean Casserole is 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.
The BEST Green Bean Casserole Recipe
This ultimate, from scratch green bean casserole has since become one our most popular recipes every Thanksgiving and Christmas. Dozens of 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 the hundreds of rave reviews below. Without exaggeration this green bean casserole has literally become world famous. Yes, it’s THAT good!
Ingredients
I developed this recipe years ago when I had about two pounds of fresh 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 cream. The wheels started turning as the blueprint for the ultimate green bean casserole recipe unfolded in my mind. And the rest is history.

Why You’ll LOVE This Green Bean Casserole Recipe
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). Ā 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. Ā This isn’t called “ultimate” for no reason and we’re confident you’re going to love it as much as we do and thousands of my readers have since I first published it in 2013!

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!). Lars’ Crispy Onions imported from Holland, for example, is made without hydrogenated oils and if you have an ALDI nearby they also carry ones imported from Holland without the hydrogenated oil.

Bake, uncovered, for 30 minutes in an oven preheated to 350 degrees F.
Let the casserole sit for about 5 minutes before serving.

Enjoy!

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 It 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.

Just a note – your ingredient list doesn’t include the crispy fried onions. Fortunately, I had read the whole blog (how could I not when the pictures are mouth watering!!) but when I got to the store with the list, I saw no onions.. Luckily, I remembered them from your pictures!
Thanks for catching that, I’ve added it to the list of ingredients!
This recipe was a complete success. The first time I made it, I didn’t have quite enough of this, and had a little too much of that, and it came out fantastic anyways. It was so popular that it was immediately requested again three days later. I get my green beans from an Asian market as they are generally higher quality than the Walmart variety when the finished product is done. However, they require more cleaning and much more aggressive end removal.
So, I wound up making this in huge batches and freezing up to 4 casseroles for a “month’s worth”. This works really well as long as the mushrooms are fully cooked- I let the pre-green bean mushroom soup simmer longer than given; I leave the onion topping off until right before they go into the oven. As long as it’s fully defrosted, the cooking times are the same if not shorter. We haven’t been able to notice any decrease in quality, and this is practically a meal in and of itself.
We tend to do batch cooking on a few days out of the month, and I was so happy that we could do it with this! My sister has always been a green bean casserole fiend, but her husband hated them. This recipe went over equally well with both! I was so excited to find this website as well; we are looking forward to trying all sorts of your other recipes.
Thank you!
Laura, you’ve made my day :) I’m absolutely thrilled that it was such a success and even won over your green-bean-casserole-hating brother-in-law! I really appreciate the detailed feedback on how you went about freezing it successfully – that is fantastic to know and will be very helpful to anyone else interested in freezing it. Thank you!! And welcome to The Daring Gourmet! Best, Kimberly
First time making a green bean casserole, used to shudder at the thought. Coming from a Greek family, we only made fresh green beans sautƩed in tomato and onion sauce. You recipe came out incredible and I used our green beans fresh from our garden. Thank you for a splendid recipe.
I’m so thrilled to hear that, Elena, thank you! And how wonderful that you were able to use those magnificent fresh green beans from your garden!
This was absolutely fantastic! I’m such a big fan of green bean casserole and have been craving it, but didn’t want to settle for the boring and processed traditional recipe, and wanted to utilize the fresh green beans I just picked up from the market! I served it with a grilled ham steak, and made a glaze with 1/4 cup fresh maple syrup, tablespoon dijon mustard, and tablespoon cider vinegar. Christmas in July! Yum!!
Tiffany, that sounds fantastic and your family/friends are a lucky bunch! You’ve got me seriously craving that entire meal right now :) So glad to hear the casserole was a hit and thank you for the feedback!
Made this for Easter and had to email the recipes to everyone as they LOVED it!!!! I wanted to make a Green Bean Caserole but did not want to use a soup!!!! This is now my FAV!!
Fabulous, I’m so happy it was such a big hit! Thanks for the feedback!
I made this this week. I made a vegetarian version (no bacon, vegetable broth) for my daughter and the baconlicious version for the rest of the family. They loved it!! Even the carnivores liked the veggie version. Thanks so much!
Wonderful! I’m happy to hear that both versions were a hit in your family. I’m still in shock that even my life-long green bean hating brother enjoyed this casserole. He said the flavor was so good that it made the green beans tolerable :) Thanks for your feedback, Robin! Best, Kimberly
hey…. are these store brought French Fried Onions- or do you have a recipe for these???
Hi Karen! Yes, they’re store bought – if you scroll down through the prep pictures you’ll see the ones I used (some fantastic ones imported from Europe with no junk ingredients). I make most everything from scratch, but there are some items, like with these, where they’re so good store bought, and made with clean ingredients, that I save myself the time and use them.
That fact is, nobody who had the dish was used to fake cheese. My friend was recently forced to go without dairy or soy due to her baby’s allergies. Bacon was actually used! Maybe that saved it. Still everybody liked the dish…you should be proud! BTW I did give away the fake cheese to my friend after that. Next time I totally will follow your recipe, exactly.
Haha! I’m totally proud of you, Ayako! Yes, make it the “right” way next time and you’ll love it! :)
