Ingredients for Slow Cooker Green Bean Casserole
GREEN BEANS: Use Frozen green beans or canned (and drained). If using fresh green beans, boil them for 4 minutes and the cool them in ice water.
SAUCE: Condensed cream of mushroom soup makes this dish super easy, but you could also use any ‘cream of soup’ like celery, potato, or chicken.
TOPPING: Crispy fried onions add a little salty crunch to this recipe, but you can also sprinkle on some seasoned bread crumbs or crushed pork rinds for a lower-carb dish.
VARIATIONS: We love an addition of cooked and crumbled bacon or a handful of shredded cheddar cheese for extra flavor!

Have always wanted a slow cooker recipe for this recipe. So glad I found yours! We don’t just

I would love to hear what you think when you give it a try, Deborah!
Loved it; so easy !!
So glad you loved it!
Have had a similar recipe for a few years now. The only difference is that instead of the cream of mushroom, it used Classico Roasted Red Pepper Alfredo sauce. Unfortunately, Classico stopped making it, so it’s back to the cream of mushroom. Thanks for posting!
Roasted Red Pepper Alfredo sounds delicious!
Won’t fresh green beans cook in 3hours in the crockpot without the blanching ahead of time? Or does the blanching retain the green color better?
I have only ever made this by blanching the green beans first so I can’t say for sure, Altie. If you decide to try it without blanching them, I would love to hear how it turns out!
This recipe is simple to make and delicious! I love making your recipes,Holly!
Thank you very much!
So glad you loved it Kim!
Always make for holiday dinners
It’s an easy favorite!
