Easy Green Bean Casserole Recipe

Could anyone else out there totally survive on casseroles alone? I know they're not for everyone, but I can't get enough. They just remind me of cozy comfort foods that warm you up with their rich and savory flavors, and Grandma's green bean casserole absolutely lives up to all the casserole hype. My favorite thing about casseroles? They're famously easy to make (which might be why they're such a hit especially for holiday meals -- nobody wants to be slaving away in the kitchen for hours).

AND, they're great make-ahead dishes for big gatherings, too. You can prep all the ingredients, bake the casserole, and then either freeze it if the event's a while away or refrigerate it if it's only a couple days away. And it tastes just as good reheated as the first time it was made -- promise. That's sort of the magic of casserole, don't you agree?

Homemade green bean casserole has to be one of my favorites. Not only does it remind me of sweet memories around the holidays, but the textures and flavors are unreal and just so good. You'll love this rendition with cracker crumbs on top because they lend a crunchy, salty topping to an already incredible dish!

What goes with green bean casserole?

Of course, green bean casserole is typically a holiday side dish, so any of your normal suspects on a holiday table really go nicely with it: turkey and gravy, mashed potatoes, sweet potatoes, or homemade cranberry sauce are all super tasty with it!

What can I substitute for cream of mushroom soup in a casserole?

So, my recipe for green bean casserole doesn't use cream of mushroom soup (even though a vast majority of recipes out there do call for it). I think soup can be a good way to make it creamy, but I'm not a huge fan of using it myself, so I make a creamy base using milk and sour cream that is divine in this casserole.

Can I mix up green bean casserole the night before?

You sure can! Just make the casserole as the instructions call for below, and then let it cool completely before covering it tightly with a lid or plastic wrap overnight. You can make it up to 3 days ahead, and you can also freeze it for up to 3 months.
