Green bean casserole is a must at any holiday dinner, especially Thanksgiving. It's a favorite side dish for good reason: the combination of creamy mushroom sauce, fresh green beans, and crunchy onions is easy to love.

You'll only need five ingredients to make this casserole, and it can be made with fresh, frozen, or even canned green beans. If using fresh or frozen, quickly cook the beans first. This can be done ahead of time if you like—then simply combine the ingredients and bake before serving.

Your Frequently Asked Holiday Questions, Answered

While green bean casserole is a Thanksgiving classic, pairing perfectly with roast turkey and stuffing, it's quick and easy enough to serve anytime. Try serving with baked ham, pork chops, chicken breasts, and sides like mashed potatoes, baked sweet potatoes, and macaroni and cheese.

“This recipe is a reminder that Green Bean Casserole is too good to only have during the holidays. Fresh green beans make this extra special, but having the option to use frozen is a great alternative in case you can’t get your hands on fresh.” —Kayla Hoang

  • Fresh green beans make this casserole especially delicious. Wash, drain, and trim the beans before steaming them on the stovetop or in the microwave.
  • Frozen green beans also work nicely. They can be steamed from frozen—cook them for less time than fresh to maintain their texture.
  • If using canned green beans, rinse and drain them before using. No need to cook them first—simply add them to the casserole and bake.

Recipe Variations

  • Add up to a half a cup of shredded cheddar cheese to the casserole mixture.
  • Add cooked, chopped bacon for a meaty touch.
  • Go all out and make a homemade version of green bean casserole.

How to Store

  • The green beans can be cooked ahead of time and stored in the fridge. The casserole can also be assembled up to a day ahead, covered, and stored in the fridge.
  • Store leftover green bean casserole in a covered container in the fridge for up to three days. Reheat in the microwave, on the stovetop in a skillet, or in the oven.

Why Is My Green Bean Casserole Runny?

First, be sure to use condensed canned soup. Since green bean casserole calls for cooked green beans, make sure they are completely drained before adding them to the mixture. Finally, make sure to cook the casserole until nice and bubbly so that it thickens up.

Are Frozen Green Beans Already Cooked?

Frozen green beans are typically blanched (very briefly steamed or boiled and cooled in ice water) before freezing.

How Long Can Green Bean Casserole Sit Out?

The casserole can sit out at room temperature for about an hour, then it should be reheated or stored in the fridge.
