This is literally the Green Bean Casserole with Canned Green Beans, and it’s sure to become your go-to for all holiday gatherings from here out. All of the things that make green bean casserole delicious are here – creamy sauce, canned green beans, French’s fried onions – except the canned cream of mushroom. So easy and SO good!
Thanksgiving isn’t complete without everything else we love that goes with it, so be sure to check out our world famous (well at least on the internet) Creamy Mashed Potatoes Recipe, Simple Leek and Sage Stuffing, and this Delicate Squash, Sage and Pancetta Stuffing.
Best Ever Green Bean Casserole
For me, Thanksgiving isn’t complete without an obscenely large batch of homemade green bean casserole. And by obscenely large, I mean there better be enough to feed 10 plus people AND enough leftovers to feed me for at least three days post Thanksgiving. I love the stuff. How could you not? Soft green beans entangled in a creamy, mushroom-laced sauce and topped off with crispy fried onions. It’s the perfect combination of creamy, crunchy and indulgent.
Plus, it’s a heck of a good way to trick your kiddos into eating their veggies. Win!
Typically, I tend to reach for the same classic recipe, but this year, I wanted to try my hand at a slightly richer, homemade version. Because while I’ll all about tradition when it comes to holidays, tradition could always use a little tweaking. In my version, hearty crimini (baby portabella) mushrooms, onions and garlic sautéed in butter are the base and foundation of the casserole, while a splash of dry sherry aids in a sweet, almost nutty undertone.
The cream portion is an equal mixture of whole milk and half and half, which I find to be the perfect combination to achieve that luscious, smooth-as-silk texture we all love about classic green bean casserole. A final splash of worcestershire sauce and a generous hand of salt complete the sauce.
Why Use Canned Green Beans in Green Bean Casserole?
Next up, the green beans. Because what’s a green bean casserole without the green beans? I love using canned green beans because they’re SO quick and require minimal preparation — and let’s be serious, when it’s Thanksgiving and you’re preparing a million dishes, an ingredient that’s ready to go is seriously welcomed. I’ve tried using fresh green beans, and they just don’t have that nostalgic factor I crave in my green bean casserole. I make sure I get a variety that has no added sodium, so I can control the amount of salt that goes into the dish.
Annd of course our casserole wouldn’t be complete without that quintessential crunchy topping – fried onions. You could go one of two ways here.
1. You could make your own.
2. You can pick up some store-bought.
I’m a from-scratch-is-better kind of gal when it comes to almost everything, but here, again for nostalgic purposes, I’m just fine using something store-bought. It’s Thanksgiving, you’re allowed to take SOME shortcuts, right? However, I’ve made this several times, and a few of the times I’ve made my own.
I’ve included the instructions if you’re feeling ambitious, but it you’re not, no worries. Really.

Can Green Bean Casserole with Canned Green Beans be Made Ahead of Time?
Yes! Don’t put the final layer of onions on top though. Prepare all the way through transferring the mixture to the baking dish. Cool completely, and then cover with plastic wrap. When you’re ready to bake, pull it out, take the plastic off, and sprinkle with onions. Bake as instructed.

Would you recommend this to be made ahead of time, or day of?
Nicole says
I would definitely make it the day of, but if you need to, you could probably make the casserole the day before (without baking it), and not the onions, then make the onions and bake the whole thing the day of.
Stephanie says
Wondering if this recipe has been changed? I love this one so much and have been using it for years!! But this time looking at it, things look different? It always specified French cut green beans.
