Green Bean Casserole has been a family favorite for millions of happy Thanksgiving diners for decades. Even now as we go to other family holiday get togethers with extended family, it always makes an appearance on the table. One reason only, it is SO DELICIOUS…easy AND kid friendly.

Green bean casserole was invented by Campbell’s Soup in 1955 because it wanted to create recipes that could utilize its cream of mushroom soup (Note: You can also use our Homemade Cream of Mushroom Soup for this recipe). With the addition of crispy onions on top it became a hit around households and with kids because of the crunchy topping.

Now, let’s discuss this recipe, because there are a lot of swap options available here even though we make this green bean casserole from scratch. Making a green bean casserole with fresh green beans isn’t as difficult as it may seem. Once you trim the green beans it only takes 5-7 minutes in your microwave to soften them as you would find in the canned variety.

Frequently Asked Questions:

Why Use Fresh Green Beans? Well as with anything the less ingredients you have the more important it becomes to use the absolute best quality ingredients you can. Canned green beans are certainly an option (and an easy one) but fresh or frozen are preferred by me because I know those beans haven’t been sitting for long. The fresher the better.

Why Use Cream of Mushroom Soup? This is a matter of nostalgia. There’s a version of the recipe  out there that has a homemade cream sauce with large sautéed mushrooms. Certainly delicious, I’ve actually made it before and it is in fact delicious, but it isn’t that flavor we all grew up with.

This green bean casserole recipe is like the kind you had as a kid but BETTER. The homemade condensed soup is a great alternative made with whole ingredients and the fried onions from the onion loaf recipe are the perfect topping.

Using fresh green beans only has one downside, trimming. Do all green beans have strings? Yes, they do but they are not as tough as they used to be so simply trimming off the end with the stem is enough to make these green beans perfectly tender for you to enjoy.

Should you slice the green beans in half? That is completely up to you, most people who make green bean casserole tend to just use regular canned green beans but if you’d like to slice them in half use a paring knife to carefully slice lengthwise down the middle. The cooking time will be decreased by about five minutes as the green beans aren’t as thick.

Ultimate Green Bean Casserole from Scratch

What Goes Into Green bean casserole:

Cream of Mushroom Soup:

The recipe calls for two cans of it. Pictured in this recipe is my homemade version (doubled) of cream of mushroom soup, but you can certainly use the canned variety. I make my homemade version and freeze it for use in these types of recipes.

If using the homemade version and you’ve got it frozen, I’d add 1/4 cup of milk to it when gently reheating.

French’s Fried Onions:

Many years ago I started making Tony Roma’s Onion Loaf for us to enjoy at home. This was a mixture of onions, milk and pancake mix that becomes the most delicious crispy fried onions you’ve ever eaten. The only thing you have to do is once you’ve fried up the onions, use some of them in the mixture then top them after the green beans are done cooking for five minutes in the oven.

I highly recommend enjoying these onions as the topping to your Green Bean Casserole recipe, but again the French’s Green Bean Casserole variety is a classic and would work out just fine too.

Slow Cooker Green Bean Casserole:

We LOVE this recipe made in the slow cooker. Double the recipe and cook on low for 5-6 hours before topping with the onions just before serving. Don’t mix in any of the onions of this version and don’t cook any longer once you top with the onions.

  1. I just made 2 of this recipe, one using fresh, & the other using canned. So I’m interested to see how they compare. How do you go about cutting up the fresh green beans? The canned French are so much smaller/skinnier.

    1. If you’re using an American green bean which is a bit thicker, you can just cut them up into pieces. Look for ones labeled haricot vert if you want more of a slimmer style. Hope this helps!

  2. Sabrina,

    If made a day in advance, what is your recommendation for reheating the next day? Would love to try it for Thanksgiving dinner on Thursday – with fresh green beans, for sure!

    Thank you…

    1. I would bake in the oven on low until heated through. Or you can assemble the day before and cook as normal. Hope this helps!

  3. i am confused about the cream of mushroom soup recipe do i have to make a double batch for the green bean casserole, because you say to use 2 cans of soup but your recipe says it makes one can of soup??

    1. Correct, my recipe for cream of mushroom soup makes the equivalent of 1 can. If you are using it for my green been casserole you will need a double batch because the green bean recipe calls for 2 cans of soup. Hope this clears up any confusion!

    1. I was planning on using frozen green beans because I have to work the morning of thanksgiving. Would letting them thaw in the fridge have the same effect as cooking them to thaw?

      1. Yes, that would work just make sure that they are completely thawed and pat dry. You don’t want any extra liquid from them still being in even the slightly frozen state. It’ll make your casserole soupy. Enjoy!

  4. If slow cooking, skip the microwave part with the fresh beans and throw them right into the cooker? Can’t wait to make :}

  5. Hello there. Im just curious what is your opinion on size glass baking dish?
    My thought was to cut this recipe in half were having a rather small thanksgiving this year. I though tour option would be best! Thanks Sabrina!!!


    1. I used a 9×13 baking dish for this recipe but if you’re cutting it half, just use a smaller size. Enjoy and Happy Thanksgiving!

    1. I made this last year, using your homemade cream of mushroom soup recipe. I was thinking of making this for a party at work. How would you recommend cooking this and transporting using a crock pot? There is no way to heat it in an oven at work. Could I bake it in the oven before work and then put it in a crock pot to take?

      1. When is your party? I have a slow cooker version coming early next week. Can you wait until monday? I have a full slow cooker friendly version you could take. I’m doing final testing tomorrow.

        1. Hi Andrea,

          You motivated me to finish this recipe for you last night, so I posted it this morning instead of the pineapple meatball recipe I was going to post. Enjoy!
