We’ve all had it. The traditional holiday green bean casserole. The one that Aunt Etna brings in the massive glass casserole dish that she inherited from Grandma Maryland. Good stuff, but not much of a ‘wow’ factor. Sorry, Aunt Etna. Well, scrap that and move on to this slow cooker holiday green bean casserole. Same idea, but oh, so much better.
My wife told me to make this again before we were halfway thru the first batch. There’s nothing about it that’s not great. Beans in creamy Alfredo sauce, flavored with water chestnuts, mushrooms and pimentos (or in my case, roasted red bell peppers) and a little cheese. And yes, French fried onions and toasted pecans. This slow cooker green bean casserole screams holidays.

Forget Grandma’s Casserole (Sorry)
I made this early enough in the fall to get fresh green beans, which I blanched first. Frozen beans work just fine too. And, if you’re like me you’ll want extra French fried onions. No, they’re not for the dish. They’re for munching on while you watch everything cook in the slow cooker. I could eat them like potato chips. Just put them in a bowl and pass it on over! I’m of the opinion that if half make it into this slow cooker holiday green bean casserole I’m doing pretty good!
I used a pretty good Alfredo sauce for this dish. I usually lean towards well, the cheap stuff. Not as flavorful, usually. Well, this really wasn’t the time for bland anything so I grabbed the top shelf brand. One I’ve used before and trusted and knew would taste great.

That Cheese
For best results, grab a piece of Parmesan from the deli section of your grocery store and grate it yourself. It makes a difference. In taste and well, how I feel about this dish. I know I put ‘the good’ stuff in there. Since grating cheese can be laborious, I used my countertop grater. It grates a ton of cheese in mere moments!
