Homemade Green Bean Casserole

Campbell’s, French’s, even Paula Dean and the good ole’ Pioneer woman all have a special take on green bean casserole.

But did you know that you can skip the canned soup and still make a delicious, homemade, and just as quick green bean casserole from scratch

I love this side dish recipe because its so simple and difficult to mess up, making it the perfect dish for the entire family to get involved in.

But don’t let its simple ingredients fool you!

Full of flavor and easy to customize with fresh mushrooms and roasted onions, some traditional recipes, like this one, are worth making year after year.

This recipe is savory and also heats up well, making it a perfect left over that tastes the same the next day.

No Soup Green Bean Casserole Recipe

Preheat oven to 400 and grease a casserole dish. Set aside.

It’s totally easy to make green bean casserole with cream of onion or cream of mushroom soup but its also totally unnecessary!

No need to run to the store to see what you have on hand when you can combine delicious fresh (or frozen) green beans in your own marinade of sauce this season.

Add butter and garlic in a skillet and heat on medium until butter is melted.

Stir in flour, chicken broth, whipping, salt and pepper – this makes a roux.

Green Bean Casserole Variations

This casserole can easily be made with and without mushrooms.

You could also use canned. You can use whole, cut frozen green beans as well.

You could also technically just add the onions on the cast iron pan and toss it in to the oven.

But I don’t think serving the skillet is that amazing, especially since you typically make this for holiday meals.

  • 1 cup chicken broth
  • 1 cup whole whipping cream
  • 1/2 teaspoon salt

  • Remove from heat and stir in fresh mushrooms, 1/2 cup French fried onions and (frozen but defrosted) French Style Green beans.
  • Mix all ingredients well.

Notes

  • Note on the casserole dish - I have dishes that go from the stove to the oven and that is the best way to handle this casserole. However, if you do not have that, simply use a pan for the first part of the recipe and transfer to a prepared casserole dish before baking.
  • You can find french style green beans in the frozen section of the store- just leave the bag in the fridge for a few hours to defrost naturally and drain any excess water.
  • In my store they sell 3.5 oz bags of French Fried Onions - I usually grab two and pour one in the mix and one for the topping.

  1. I’m curious if you’ve made this and put it in a casserole the day before and then finish cooking in the oven the next day?

    1. I have not, but there should be no issues. Just do not add the crunchy onions ahead of time.

  2. Would it work with fresh green beans or should they be cooked first?

  3. How can you say from scratch if you are using nasty unhealthy fried onions from the store?!

    1. Trisha Haas says:

      Not all homemade recipes consist of entirely and only homemade items. All these ingredients come from the store in some fashion – short of raising cows and a farm, even the green beans and dairy come from a store. Regarding the onions, if you want to take the time to make fried onions personally to top the recipe, you can. But that’s often unrealistic for a 20 minute meal and would def stretch it out and put a lot more time constraints on a holiday side dish like this. Additionally, we are not a healthy (that term is used differently by different people) site and therefore do not claim any particular recipe falls within a dietary need as each person can decide what that looks like for them.

      This recipe is a from-scratch recipe for most people that use a traditional canned green bean and canned cream of soup and instead replaces with real green beans, real cream, and real mushrooms.

      Its an excellent recipe and if you want to leave out storebought fried onions, that is fine as well.

  4. I would like to make this a day before serving. You mentioned not putting the fried onion rings on top, until ready to bake.
    But what about the fried onion rings already mixed in the dish?

    1. Trisha Haas says:

      The ones in the dish are already in the moisture so to speak so they will be soft. The ones on the top wont be crispy if you pre-add them, which is their role in the recipe. Does that make sense?
