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

A Note From Our Recipe Tester

Ingredients

1 (10.5 or 10.75-ounce) can cream of mushroom soup
1/2 cup milk
1/8 teaspoon pepper
Butter, for the casserole dish
4 cups cooked green beans
1 1/3 cups French-fried onions

Steps to Make It

Gather the ingredients. Preheat the oven to350 F/177 C/Gas 4.
Mix the soup, milk, and pepper in a buttered 1 1/2 to 2-quart casserole dish.
Add the green beans and 2/3 cup of the French-fried onions.
Stir the mixture together.
Bake the casserole for about 25 minutes or until bubbly around the edges.
Top with the remaining 2/3 cup of fried onions and bake about 5 more minutes or until the onions are lightly browned. Serve and enjoy!

Tips

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.
