A good green bean casserole is an absolute must at the holiday dinner table. This simple, classic Thanksgiving and Christmas recipe using the traditional can of cream of mushroom soup, but uses fresh green beans, mushrooms and onions, alongside the requisite can of French-fried onion, to create a tender, juicy, and still tender crisp casserole.

For an interesting twist to this classic recipe, why not try making an Asparagus Green Bean Casserole? Or some bacon wrapped green bean bundles?

The idea of combining green beans, cream of mushroom soup, and fried onions might seem strange to some people, but it’s a Midwestern US tradition. There’s just something wonderfully satisfying about tender crisp green beans soaked in rich, flavorful mushroom-y sauce and topped with fried onions.

Whether served alongside a giant roast turkey or just as a side dish for a weekend meal, this green bean casserole is a staple of any holiday menu.

How to Store & Reheat Your Green Bean Casserole

Despite the rather saucy texture of this casserole, it actually stores and reheats really well.

You just need to tightly wrap the entire casserole dish in plastic wrap and then store the whole thing in the fridge. When you want to eat some, just scoop out a portion and put it in a serving bowl, and microwave the whole thing for about 30-90 seconds, or until piping hot.

You can also put it in the oven at around 350 Fahrenheit for 15 minutes until bubbly, but you might start to see the milk sauce separating if you leave it too long.

Do You Have to Use Cream of Mushroom Soup

Not everyone is a big fan of canned mushroom soup, so you might be wondering if you could substitute other soups instead or just skip it entirely. While you could certainly just use a different type of condensed soup, like Campbell’s cream of chicken, for example, unless you are allergic to mushrooms, you really should definitely stick with the cream of mushroom.

The soup provides a lot of great salty, umami flavors and helps bind the dish together. And really, this is THE classic recipe, so canned soup once or twice a year is fine.

The fresh mushrooms really make this amazing for the mushroom lovers, but if you aren’t a fan you can leave them out as the aren’t the traditional recipe. But you know me and my love of mushroom anything! More is always better!
