Easy Green Bean Casserole is a classic holiday side dish made with tender green beans, a creamy sauce, and crispy fried onions. Our version uses both cream of mushroom and cream of chicken soup for extra flavor, while canned green beans keep prep to just a few minutes.

Green Bean Casserole has been a Thanksgiving favorite for generations, and it is one we love because it is simple, make-ahead friendly, and easy to double when we are feeding family. Adding the crispy onions near the end keeps the top golden and crunchy, which make this dish even more tasty.

Why You’ll Love It + Why It Works:

  • 5-Minute Prep. Canned green beans and condensed soups keep this classic side quick and simple.
  • Make-Ahead Friendly. Assemble the casserole ahead of time and save the crispy onions for the end.
  • Extra Creamy. Cream of mushroom and cream of chicken soup create a rich sauce with plenty of savory flavor.
  • Crispy Topping. Adding the fried onions during the last few minutes keeps them golden instead of soggy.
  • Easy for Holidays. It uses simple pantry ingredients and can easily be doubled when you are feeding a bigger group.
Ingredients for green bean casserole recipe.

Easy Green Bean Casserole Ingredients

  • French-style green beans, drained (3 cans, 14.5 ounces each): Create the tender green bean base and keep prep quick. Drain them very well so extra liquid does not make the casserole watery.
  • Condensed cream of chicken soup (1 can, 10.5 ounces): Adds creamy texture and extra savory flavor to the sauce.
  • Condensed cream of mushroom soup (1 can, 10.5 ounces): Adds the classic mushroom flavor we expect in Green Bean Casserole and combines with the chicken soup for a rich, creamy sauce.
  • Milk (¼ cup): Loosens the condensed soups just enough so the sauce coats the green beans evenly. We like at least 2% milk, but half-and-half can be used for a creamier texture.
  • Salt and black pepper, to taste: Season the casserole and bring out the savory flavors. Taste before adding much salt since the soups and crispy onions already contain quite a bit.
  • Crispy fried onions (1 can, 2.8 ounces): Add the classic crunchy topping and plenty of savory flavor. Add them near the end of baking so they stay golden and crisp instead of getting soft. If your family does not like fried onions, use crushed Ritz crackers or even Panko breadcrumbs toasted in butter.

How to Make Green Bean Casserole

PREHEAT. Preheat the oven to 350°F.

COMBINE. In a large bowl, stir together the well-drained green beans, cream of mushroom soup, cream of chicken soup, milk, black pepper, and salt to taste.

ASSEMBLE. Spread the mixture evenly in a 9×13-inch baking dish.

BAKE. Bake for 18 to 20 minutes, or until the casserole is hot and bubbling around the edges.

TOP. Sprinkle the crispy fried onions evenly over the top and bake for another 5 minutes, until the onions are golden and crisp.

SERVE. Let the casserole rest for a few minutes, then serve warm.

Green Bean Casserole Variations:

This classic Green Bean Casserole is easy to switch up depending on what your family likes or what you have on hand.

  • Add Bacon. Stir in cooked, crumbled bacon for extra savory flavor.
  • Make It Cheesy. Add shredded cheddar cheese to the casserole before baking.
  • Add Garlic. Mix in a little garlic powder or cooked minced garlic for more flavor.
  • Switch the Soup. Replace one of the cream soups with cream of celery for a slightly different flavor.
  • Change the Topping. Use buttery crushed Ritz crackers or toasted Panko breadcrumbs instead of crispy fried onions.
  • Add More Veggies. Sautéed mushrooms or onions can be mixed in for a little more texture and flavor.

  • Drain the Beans Well. Extra liquid from the canned beans can thin the sauce and make the casserole watery.
  • Taste Before Salting. Condensed soups and fried onions already contain salt, so season after everything is mixed together.
  • Look for Bubbles. The casserole should be hot and bubbling around the edges before you add the crispy onion topping.
  • Add Onions Last. Save the crispy fried onions for the final 5 minutes so they stay crunchy and do not burn.
  • Using Fresh Green Beans. For a fresh-bean version, use our Fresh Green Bean Casserole recipe, which is developed specifically for fresh beans.
  • Make It Ahead. Assemble the casserole without the onion topping up to 48 hours ahead, cover, and refrigerate. Add the onions during the final 5 minutes of baking.
  • Allow Extra Bake Time. A casserole going into the oven cold from the refrigerator may need about 10 extra minutes to heat through.

Recipe FAQ

Why is my Green Bean Casserole runny?

The most common cause is excess liquid from the green beans. Drain canned beans very well before mixing them with the sauce, and cook and drain any extra vegetables before adding them.

Can I make Green Bean Casserole ahead of time?

Yes. Assemble the casserole without the crispy onion topping, cover, and refrigerate for up to 48 hours. Add the onions during the final 5 minutes of baking, and allow a little extra baking time if the casserole is cold from the refrigerator.

How do I make Green Bean Casserole gluten-free?

Use certified gluten-free condensed soups and a gluten-free crispy onion or breadcrumb topping. Always check the labels on packaged ingredients since brands can vary.

Can I use fresh green beans?

For the best results, use our Fresh Green Bean Casserole recipe, which is developed specifically for fresh beans and their different texture and cooking time.

How do I store leftover Green Bean Casserole?

Store cooled leftovers in an airtight container in the refrigerator for 3 to 4 days.

Can I freeze Green Bean Casserole?

Yes. Cool the casserole completely and freeze it without the crispy onion topping in an airtight freezer-safe container for up to 2 months. Thaw overnight in the refrigerator, reheat in the oven until hot, and add fresh crispy onions near the end.

    What can I substitute for the onions

    1. Lil' Luna Team says:

      You can leave them off or substitute crushed buttery crackers, toasted breadcrumbs, or even a sprinkle of shredded cheddar cheese for a tasty crunchy topping. I hope you enjoy the casserole!

  2. Sandy says:

    why don’t the instructions change for baking with doubling the recipe?

    1. Lil' Luna Team says:

      Great question! The 2x feature on the site only has the capability to adjust the ingredient amounts and does not automatically update the instructions yet.

      You will still follow the same steps, just keeping an eye on things like bake time or pan size since those can change a bit when doubling.

  3. Sandy says:
