There are a few classics that you simply don’t mess with when it comes to Thanksgiving dinner. Believe me on this one. Case in point? Green bean casserole.
I’ve tried making my own french fried scallions. FAIL. I’ve tried making my own substitute for cream of mushroom soup. FAIL.
Friends, don’t do it. Don’t try to be a Thanksgiving hero with this traditional side dish. Take it from me, I’ve found only one – and one way only! – to improve on the original. Enter my Twice the Onion Green Bean Casserole.
Who are we kidding? We all know why we love this turkey day staple. Those crispy, fried onions that sit on top. All the flavor, all the crunch. They’re definitely the star of the show.
Well, they really are now in my Twice the Onion Green Bean Casserole. I’ve followed the traditional recipe but upped the amount of onion deliciousness. Simple enough, right?
When someone noted that it’s the best green bean casserole recipe they’ve ever tasted, it was a nudge that I needed to share this simple twist with all of you. You’re welcome.
Might I also recommend that you serve this green bean casserole recipe alongside three other of my side dish favorites?
This Twice the Onion Green Bean Casserole is beyond easy to make and uses simple ingredients to make the process an absolute no brainer. I prefer to use frozen green beans rather than the canned variety that so many recipes call for – mushy green beans are in no way worthy to be included in a holiday tradition.
And of course, it wouldn’t be a French’s green bean casserole recipe without those amazing fried onions!
How to Make Green Bean Casserole
 Prepare green beans according to package directions. I prefer the Bird’s Eye brand that I can microwave in the package.
 Meanwhile, in a 9″ x 13″ baking dish or 3 quart casserole, stir together soup, milk, soy sauce and pepper.
 Add prepared green beans and ONE can of French fried onions and stir until just combined.
How Long Do You Cook Green Bean Casserole?
 Bake at 350 degrees for 25 minutes or until bubbly.
You will then top the casserole with a second can of French fried onions and bake an additional five minutes or until golden.
Can You Make Green Bean Casserole Ahead of Time?
YES! If you want to get a head start on your holiday dinner prep, the day before you intend to serve this Twice the Onion Green Bean Casserole, you can follow the recipe through step four and then allow the casserole to cool completely before putting it in the fridge.
Prior to serving, you’ll simply reheat the casserole before topping the casserole with a second can of French fried onions and bake an additional five minutes or until golden.
We love this Twice the Onion Green Bean Casserole so much that it’s now a year round side dish and no longer regulated to just our Thanksgiving table. It’s just as amazing and comforting for a Sunday dinner as it is in November!
