I know Halloween is tomorrow, but I’m already thinking about Thanksgiving side dishes.

It’s my first Thanksgiving back in the States after two years in Canada. The last two years I prepared the whole feast on my own and served WAY too much food to my family of 6.

I couldn’t resist. It was so hard to watch all my friends and family on social media enjoying a Thanksgiving break, while it was just a normal Thursday up in Canada.

Crock Pot Side Dishes for Thanksgiving

One saving grace was being able to use my crock pot for side dishes. I actually used my friend’s awesome triple crock pot to make my Crock Pot Sweet Potato Casserole, Sausage Stuffing and Macaroni and Corn Casserole. That left my oven wide open for homemade rolls and and my perfectly roasted Turkey.

What I didn’t get to make was a classic green bean casserole. But this year, I am totally making it… and it’ll be in my slow cooker too!

I stuck with the classics of cream of mushroom soup, Worcestershire sauce, and of course green beans. But rather than using the canned version I went with fresh.

I did this because after 4 hours in a crock pot, the canned green beans would be straight mush. The fresh green beans are cooked perfectly after 4 hours and are still tender without tasting like baby food.

I also didn’t add the french’s fried onions until the very end because I didn’t want them to become mushy either.

One thing I did add was a little bit of grated parmesan cheese, which I think made a great addition.

Crock Pot Green Beans Are Easy To Make

Just toss in all the ingredients except the onions and turn it on low for 3 hours. After three hours, toss in half of the onions and stir. Crank the heat up to high for one hour, stir, then add the remaining onions and you’re ready to serve!

  1. I followed this recipe to a T and I had to throw it away. After 4 hours, the green beans were still hard and everything was watery. Not sure what I could have done wrong.

    1. Oh man, I’m so sorry the green beans didn’t get soft even after 4 hours!? That is very bizarre, I honestly don’t know what could have gone wrong? Was the crock pot getting enough heat?

    When we make this for the work potluck, we do used the canned beans but we only have the crockpot on for about an hour as all we are doing is heating it up. I believe that sis puts it on high for the hour.

    I tried this for the first time hoping that I have found the answer to cooking my favorite casserole while the turkey takes up all the oven space. I was very disappointed with this recipe after 4 hours on high the beans were still not done. I would definitely pre-boil the beans first. I have never had any luck with vegetables in the slow cooker before I should have known. I do like the addition of Parmesan cheese in the recipe it was different than the one I usually use.

    1. Sorry your green beans weren’t done to your liking. I am a fan of a more firm green bean than a mushy one, which is why I like to use fresh green beans for this recipe. You could definitely substitute the fresh green beans for canned or, like you said, pre-boil them to you desired texture. Hope that helps!

    What size crock pot did you use? I know this says serves 6, and I have about 11 people. I want to try to double the recipe but I am nervous about size and time. What do you think I should do? I have a 4.5 quart crock pot.

    this recipe is wrong!!!!! Needs 2 cans of soup,not 1, disappointed I had to fix it and then extra time in pot caused them to be a little soggy. Good taste though

    1. I’m sorry you didn’t get the desired outcome. I think that the extra soup is probably personal preference, it would definitely make it more of a soupy/soggy consistency, rather than more focused on the beans. But if that’s the way you like it, then go for it! 🙂

    I don’t know how it happened, but somehow you forgot cheddar cheese… I can’t imagine a green bean casserole without cheddar. Otherwise a perfect recipe for when the oven is occupied!!!
