What Are the Best Green Beans to Use in Green Bean Casserole?

For this easy green bean casserole, we call for canned French-style green beans because they require the least amount of attention, making this recipe super simple to make, no matter what your kitchen skills are.
If you’d rather use frozen green beans, you can use frozen French-style, cut or whole green beans, but for the best green bean casserole, be sure check out the recipe variation, which gives complete instructions on how to prep them before adding them to the other ingredients, so they will be tender when the casserole is baked.
We don’t recommend fresh green beans for this recipe, because you’d have to cook them first (requiring 8 to 20 minutes of additional cooking and after all that effort, they still may come out stringy and tough after baking.

How Can I Store and Reheat Green Bean Casserole?

If you’re lucky enough to have any leftovers, Green Bean Casserole is delicious when reheated! Just know that the fried onions won’t be crisp after being stored. But that’s ok--simply sprinkle the casserole with a few more after heating. It will be a comforting addition to any lunch or leftovers dinner night.
Fridge: Follow the make-ahead directions in our FAQ below. Cover leftovers with plastic wrap and refrigerate any leftovers immediately after the meal.
Reheat: To reheat green bean casserole, spoon the casserole into a microwavable dish. Cover loosely with plastic wrap. Reheat on medium-high (70%) until thoroughly heated. The onions will no longer be crispy. You can sprinkle additional crispy fried onions before enjoying.
Freeze: We do not recommend freezing green bean casserole, as the beans will become mushy when baked and the casserole can become watery.

Tips from the Betty Crocker Kitchens

  • tip 1
    To make sure your baking dish holds 1.5 quarts (6 cups), use a liquid measuring cup to pour water into the dish until it's full. There should be enough room for the green beans to not completely fill the dish.
  • tip 2
    Green Bean Casserole with Frozen Green Beans: Frozen French-style green beans can be substituted for the canned beans. Give frozen beans a quick rinse under cool water in a colander and shake off excess water before mixing with the soup and milk. Alternatively, 2 bags (1 lb each) frozen cut or whole green beans can be substituted. Cook as directed on bag for minimum time. Drain; stir into soup mixture. If prepping ahead of time, cover tightly and store overnight in refrigerator before baking. In Step 2, bake about 30 minutes or until beans are tender.

Substitute Other Condensed Soups: You can substitute your favorite cream-style condensed canned soup for the cream of mushroom soup, such as celery or cream of chicken.
Additional Seasoning: For additional flavor, add 1/4 teaspoon garlic or celery powder or ground pepper.
Chopped Vegetables: Stir in 2 tablespoons finely chopped sun-dried tomatoes in oil (drained) or diced pimientos (drained) with the green beans.
Other Additions: Instead of the crispy fried onions, try some crumbled crisply cooked bacon, crushed seasoned croutons, nacho-flavored tortilla chips, buttery crackers, or sliced or slivered almonds over your Green Bean Casserole right before serving.

How Do You Keep Green Bean Casserole from Getting Soggy?

Use these simple tips to have green bean casserole that has the perfect creamy sauce and crunchy fried onion topping: Start with canned green beans that have been drained or frozen green beans that have been cooked and drained (see the variation above). Any liquid from the beans will make your casserole watery. Only add 1/4 cup milk with the condensed soup—do not add the water as directed on the can. Add the crispy fried onions during the last 5 minutes of baking or they will absorb some of the sauce and become soggy. The onions will absorb sauce as they sit or if there are leftovers, when stored in the refrigerator.
Bake the casserole just before serving it. When reheating leftovers, the onions will still add their flavor to the dish, but if you like the crisp texture on top, simply top the reheated casserole with additional onions right before serving.
