 Hi everyone! My name is Bernice and I am so thankful to be a contributor here at Noshing With The Nolands. On my blog Dish ‘n’ the Kitchen, I love to create new recipes for old school classics, like today’s Green Bean Casserole Recipe, as well as share my versions of delicious ways to feed a family. Sometimes…there’s even cake!

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.

Bright green beans sit in a old fashioned grey colander.

What resulted was an unappetizing grey-green mush that 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. I like using fresh green beans too as opposed to frozen green beans; much better flavor!

As the old saying goes; ‘we eat with our eyes’ and this casserole is very visually appealing. At 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 is 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 for cooking time in a pot of boiling water where they partially cook. Next, the green beans are removed from the boiling water and plunged into an ice water bath so that the cooking process stops immediately and preserves the color.

Voila…now you have beautiful green beans!

Green Bean Casserole Sauce

Making mushroom sauce from scratch may not be as easy as opening up a can of soup, but it adds so much more flavor to this casserole. Start with a basic Béchamel or ‘white sauce’, then build your own flavors.

The ‘Zesty’ in this recipe comes from the addition of Worchestershire Sauce, Grainy Mustard, Freshly Ground Black Pepper, and finely grated Parmesan Reggiano. This trio is a powerhouse flavor combination!

Let’s not forget the mushrooms! By blitzing them in a food processor, their surface area for flavor release increases dramatically.

Next, frying them until their juices are released condenses their flavor even more. They add such an earthy, subtle flavor to this casserole that is not to be missed.

Can You Freeze Green Bean Casserole?

Green Bean Casserole is 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 to get it all nice and hot and bubbling before serving. It should only take about 25 minutes.

    Could Browned Onions replace the French Fried Onions ? I’m eliminating all processed foods from our diet. Too many of the bat fats we aren’t supposed to have. I would carmelize the onion in Olive Oil, with some garlic.
