There is nothing more traditional than having Green Bean Casserole for the holidays in my family. To make it easier so that I can spend more time with family during the holidays I decided to give this delicious casserole recipe a try in the slow cooker and came up with this Crockpot Green Bean Casserole recipe.
It is so easy and frees up the oven so that you can make other recipes in it during the holidays. So that is win/win for me! I hope you like it as much as we do!
This wonderful recipe is so good in the crockpot, your guests will not even know that you did not bake it in the oven. You only need 5 simple ingredients for this easy side dish. Yes only 5 and you may have them in your kitchen right now! Combine all the ingredients (except French onions). In your slow cooker and mix well. Cook on High for 2 Hours or Low for 4 hours. Top with French’s Fried Onions for another 30 minutes, or transfer to a 9x13 dish and place in the oven for 15 minutes at 350 Degrees to brown onions. I personally chose just to complete the recipe in my crockpot.
Be sure to try this yummy Crockpot Green Bean Casserole for Thanksgiving, Christmas or any other holiday! This recipe so easy to make and will soon become a family favorite! Trust me when I say that it is the perfect side dish to make for your next holiday dinner.

Yes, they should be drained.

This is a great idea for the holidays because you can free up your oven for all the other side dishes! 🙂

What size of crockpot do you use?
Melissa@StockpilingMoms
6 qt.
Kelly
Does just doing the onions in the crockpot for 30 mins also brown them, or do they only get brown if you put them in the oven? Thanks!
Melissa@StockpilingMoms
You will only brown them if you transfer to the oven.
Becky K
Would like to make this for a potluck for our homeschooling community. Any problems with doubling the recipe?
Melissa@StockpilingMoms
None at all! Enjoy!

I had this at a friend's house and it was so good I decided to make it for my family Thanksgiving. Do I cook it covered or not covered?
Melissa@StockpilingMoms
Covered - always with the lid for a crockpot.
shelby
if i make a double recipe, would the same time be okay or would it need to cook longer?
Melissa@StockpilingMoms
It depends on if you use a larger crockpot.
Shelby
I have a 6 qt. 🙂
Karilyn
It says to add all ingredients except the onions, but don't you add the ones that go into the mix and just not the topped ones you brown? I'm confused lol!
Melissa@StockpilingMoms

the canned beans don't go too soggy?
Melissa@StockpilingMoms
No, they don't 🙂
Carrie
How long would you need to cook this in a 6 Qt crockpot if you are doubling the recipe? TIA!
Melissa@StockpilingMoms
I would just add 2 hours.
Molly
How many ounces should the cans of cream of mushroom soup be?

10.5

It really does save a lot of time/space to make the casserole this way. I appreciate that you kept this recipe very simple for people. I will be making this to take to a Thanksgiving dinner this week, and I will also be transporting two other side dishes in crockpots as well so that I don't have to worry about using their oven. Happy Thanksgiving!
Martina
Could I use frozen green beans instead of canned? Would that create too much liquid?
Melissa@StockpilingMoms
Yes you can. Reduce you liquid by 1/2 cup.
Nancy Ford
Sliced or whole green beans?
Melissa@StockpilingMoms
We used cut whole green beans.
Tracy
Can you use fresh green beans?
Melissa@StockpilingMoms
Yes but you may need to let it cook a little longer. I always blanch them first in hot water before I use them in the slow cooker. They may also produce a little more "water" when cooking.
