Who Wrote the First Green Bean Casserole Recipe?
During the days of early convenience cooking, when processed food was becoming vogue, Campbell’s employed a team to develop recipes using their canned products.
The original Green Bean Casserole was invented in 1955 by Dorcas Reilly who simply mixed a can of Campbell’s cream of mushroom soup (or cream of chicken soup) with canned green beans.
What resulted was an unappetizing grey-green mush which really held no appeal at all. As it turned out, the best thing to do was to top the casserole with French’s fried onions.
The crispy onions added a textural component to the dish in addition to covering up the hideous casserole. Problem solved!
How to Make A Beautiful Green Bean Casserole
This green bean side dish is entirely made from scratch and it is a little more work than the original. However, that extra elbow grease pays off when you see and taste the final dish.
As the old saying goes; ‘we eat with our eyes’ and this casserole is very visually appealing. On first glance, you see the crispy golden top layer but where this casserole really shines is inside.
Here are a few recipe tips to help you create the very best green bean casserole:
Blanch the beans. The second thing everyone notices in this dish are the vibrant green beans. Blanching vegetables is a very easy technique and can be used in so many applications.
The fresh beans take a quick 4-minute dip in a pot of boiling water where they partially cook. Next, the beans are removed from the boiling water and plunged into an ice water bath so that the cooking process stops immediately.
Voila…now you have beautiful green beans!
How to Make the Mushroom Cheese Sauce
Making mushroom sauce from scratch may not be as easy as opening up a can of soup, but it adds so much more flavour to this casserole. Start with a basic Béchamel or ‘white sauce’, then build your own flavours.
The ‘Zesty’ in this recipe comes from the addition of Worchestershire Sauce, Grainy Mustard, and finely grated Parmesan Reggiano. This trio is a powerhouse flavour combination!
Let’s not forget the mushrooms! By blitzing them in a food processor, their surface area for flavour release increases dramatically.
Next, frying them until their juices are released condenses their flavour even more. They add such an earthy, subtle flavour to this casserole that is not to be missed.
Can You Freeze this Casserole?
Yep! It’s super easy to freeze and re-heats well which makes it THE perfect make-ahead Thanksgiving dinner side dish.
To freeze, follow the recipe until you reach the baking step. Instead of baking the dish, wrap it well with plastic wrap and freeze for up to two weeks.
Finally, on the day of your dinner, just thaw and follow the remaining steps in the recipe.

I am pretty sure you are not surprised that I have never had a green bean casserole and didn’t even know it was a thing 😉 . But I like what I see in your pictures, and the “real” ingredients. I’m sure the flavors together must be sensational.
No, I’m not surprised! Actually this was my first Green Bean Casserole too. I really wanted to create a recipe that everyone could love…Green Bean Casserole traditionalists and newcomers!
Green beans and mushrooms are a match made in heaven. Adding bacon to the mix is genius! I think this would be the perfect addition to the holiday table. Thanks for sharing.
Bacon makes everything better! I just love all the flavours in this casserole and I hope you do too.

Thank you for making this amazing Thanksgiving side dish and giving it some meaning! In my house we always had green bean casserole for family get togethers but all the ingredients were from a can. I love that I can still have this dish but now enjoy REAL flavor from it!
There’s something to be said for shaking up traditions! I’m anxious to hear your feedback on the recipe. Happy Thanksgiving!
I’ve never had green bean casserole and yours looks so rich and delicious! Also your styling is on point. Yum!
Truthfully, this was my first Green bean casserole. I just could never bring myself to make one with a can of soup. lol
Bernice, you’ve made over a classic Thanksgiving favourite into a healthy side! Beautiful!
Yes! That was my mission…I’ve never cared for recipes using canned soup (although my mom does make a mean tomato soup spice cake).
I’ve never tasted green bean casserole, and have never been tempted. Until now. This one looks so delicious, and I love that there’s no canned soup. This is going on my holiday table for sure.
Me too! My main goal when I was testing this recipe was to get rid of the soup.
I love this upgrade to boring old green bean casserole recipes. A great way to shake up the Thanksgiving menu.
I love to shake things up, why go with boring right? Thanks for stopping by Sharon.
Green bean casserole is always one of my favorite Thanksgiving dishes, and your version looks delicious. Can’t wait to give this a try over the holidays!
I hope it lives up to your previous casserole standards!
