Crockpot Green Bean Casserole - Family Fresh Meals Holiday recipe

Here’s how you make green bean casserole in the slow cooker!

For a lot of families, green bean casserole is the traditional veggie dish that you have to have on your Thanksgiving table. This is a deceptively simple recipe – just green beans in a cream-soup sauce, topped with French-fried onions – but the whole is definitely greater than the sum of the parts. For some reason no one can explain, the blend of creamy soup and crunchy onions elevates plain old canned green beans to the level of art.

The only problem with making this as part of your Thanksgiving meal is that there are so many other parts of the meal you have to worry about at the same time. This casserole isn’t hard to make at all, but it takes about half an hour – and it’s hard to find that half an hour when you’re busy trying to juggle turkey, stuffing, gravy, potatoes, and cranberries. In the rush to get everything onto the table at the same time, it’s easy for the veggies to slip your mind.

So, once again, the Crockpot is here to save the day. Whenever you have a spare minute, you can just mix your beans and sauce up right in the pot, sprinkle the onions on top, and put it on high. In a couple of hours, your casserole will be piping hot and topped with a gorgeous, crunchy crust. And if it turns out the rest of the meal isn’t ready at that point, the dish can sit happily on the warm setting until you need it.

In fact, the Crockpot makes this holiday recipe so easy and good, you’ll want to enjoy it all year round.

    I’d like to try this with fresh green beans, I guess I should Blanche them first. Will let you know.

  2. This is one of my favorite side dishes for both Thanksgiving and Christmas!

    1. Probably a dumb question…do I need to melt the butter before adding it? Thanks!

  3. I noticed the recipe in the article says 3 cans of green beans and the recipe in the printable version says 2. Can you clarify which it is?

    1. I am so sorry about that Nicole. It is 3.

        Can I please get your original recipe not using condensed soup. It was great and I want to make it again. Thank you! Melanie

        1. Yes Melanie, I will email it to you 🙂

          1. May I please have this recipe using prepared soup? Thank you!

          2. Just omit the heavy cream if you are using prepared soup.

  4. The onion topping doesn’t get soggy?

    1. That is something I am wondering as well.

    2. I am wondering the same. Maybe you’re supposed to cook with the lid off?

      1. If you are worried about the onions getting soggy (they will not be as crispy as the oven version), you can add the topping on at the very end of the cooking before serving.

    I made this on Monday night, did not want to try anything new on Thanksgiving, it turned out wonderfully!! I am so doing this on Thanksgiving Day!!!

    1. 5 stars
      So glad you loved it Theresa!!

  6. Does it really only serve 4? Typically crock pot recipes serve a lot more than that. We will have about 17 at the table. I can’t imagine that I need to make 4 times as much as this recipe? I figured I would double it & that would be enough…especially considering all the other side dishes at Thanksgiving. Can you tell me what you think?

    1. Oh my gosh Kim, that should read 8. I will make sure that is changed right now 🙂

  7. 4 stars
    Would it be possible to double this recipe? I have a work lunch and this would be the perfect recipe and the perfect way to have it ready at that time. Thanks, Amanda

    1. Yes! Make sure you have a large crockpot… a 6qt should be big enough 🙂 You might need to increase the cooking time by 30 mins or so. I hope that helps!

  8. McKenzie White says:

    We are making this for thanksgiving next week, I’m excited! Wondering if I can substitute the cream for milk? Thanks!

  9. I followed the instructions precisely. Doubled everything as it was for a large group of people. It turned into soup. Had to dump the the whole pot. I could have just cried.

    1. Hmmm. That is strange Desiree. I can only speak for the recipe as written, not doubled, but I would like to figure this out. Did you remember to double the flour as well? With 3 cans of green beans to 1 can of soup, it’s seems odd that it was soupy. Sorry again that your double batch did not turnout 🙁

      1. Do you add a can of milk for the condensed cream of mushroom soup and more milk? Then drain the green beans, right?
