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!

ULTIMATE Green Bean Casserole (1)

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!

ULTIMATE Green Bean Casserole (2)

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!

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. Transfer the bacon/mushroom mixture to a bowl and set aside.

ULTIMATE Green Bean Casserole (6)

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.

ULTIMATE Green Bean Casserole (7)

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.

ULTIMATE Green Bean Casserole (8)

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).

ULTIMATE Green Bean Casserole (9)

Bake, uncovered, for 30 minutes in an oven preheated to 350 degrees F.

Let the casserole sit for about 5 minutes before serving.

  • 3 slices thick-cut bacon , diced
  • 1/2 cup finely chopped yellow onion
  • 2 cloves garlic , minced
  • 12 ounces fresh button or cremini mushrooms , chopped
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 1 cup half-and-half
  • 1 cup chicken broth
  • 1/2 cup shredded white cheddar cheese
  • 3/4 teaspoon salt
  • 1/4 teaspoon freshly ground black pepper
  • 1 pound fresh green beans , trimmed, halved, and blanched (boil 5 minutes, place beans in ice water for a couple of minutes, drain)
  • 1 can quality French fried onions
  • or gluten free French fried onions


  • Preheat the oven to 350 degrees F.

  • Fry the bacon in a large skillet over medium-high heat until crispy. Add the onions and cook until soft and translucent, about 4-5 minutes. Add the mushrooms and garlic and cook for another 4-5 minutes until the mushrooms are soft. Transfer the mixture to a bowl.

  • Melt the butter in the same skillet and whisk in the flour. Once combined, continue whisking for another 2 minutes until the mixture has slightly deepened in color. Add the half-and-half and chicken broth while constantly whisking to prevent lumps. Once slightly thickened, add the cheese and whisk until melted and combined.

  • Next add the mushroom/bacon mixture along with the salt and pepper. Let the sauce simmer for a couple of minutes, then add the green beans. Stir to combine.

  • Pour the bean mixture into a 9x13 casserole dish and sprinkle the French fried onions all over the top. Bake uncovered for 30 minutes until bubbling and the onions are golden and crispy. Let sit for 5 minutes before serving.



Preparing in Advance: Everything can be done in advance except for adding the crispy onions, otherwise they'll get soggy. Add those just before baking. Also, let the casserole sit for at least 30 minutes after removing it from the fridge before baking.
