Why Green Bean Casserole Became a Holiday Classic

Tender green beans in a silky mushroom sauce, finished with crunchy golden onions, make a dish that feels like home. It became a staple of American Thanksgiving tables in the 1950s and has stayed there ever since.

The Secret to Bright, Crisp Beans

Cooling the beans in ice water right after blanching keeps them vivid green and slightly crisp, even after baking. A creamy sauce built from fresh mushrooms and garlic adds far more flavor than you would expect from such a simple dish.

Make It Ahead, Bake It Fresh

You can assemble the casserole a day ahead and add the crispy onions just before it goes into the oven. That keeps the topping crunchy and frees up your holiday morning.
