This Easy Green Bean Casserole has been a staple on our Thanksgiving table for my entire life, but it’s simple enough for your next weeknight dinner.

The quick make-ahead side dish is perfect with a holiday turkey, roasted chicken, or a cozy pot roast!​​​​​​​

Classic Green Bean Casserole Recipe

The holidays just wouldn’t be complete without an old-fashioned, easy green bean casserole! I grew up with this recipe, and it’s now a dish that I serve to my own family on a regular basis. There’s no need to wait until Thanksgiving to enjoy the casserole, which comes together with just 6 ingredients in about 10 minutes. Best of all, French’s Green Bean Casserole can be prepared in advance to cut down on the last-minute chaos of getting dinner on the table. Ideal for busy weeknights!

The Best Green Bean Casserole

I’ve tried many different green bean casserole recipes over the years, but I always come back to the classic version originally created in 1955 by Dorcas Reilly at the Campbell Soup Company. The dish includes green beans, cream of mushroom soup, and french fried onions, and has since become known as Classic Green Bean Casserole. French’s (the company that makes the fried onions) also has a similar recipe for French’s Green Bean Casserole. This old-fashioned dish is the ultimate comfort food for so many Americans of my generation!

Which Green Beans for Casserole?

Our family prefers frozen French-cut green beans in this dish, which is a slight departure from Campbell’s original recipe that’s made with cooked cut green beans, or French’s recipe that calls for canned green beans. The French-cut green beans are thinly-sliced, giving them a softer texture in the casserole. If you prefer, you can substitute with 4 cups of fresh green beans, 4 cups of frozen cut green beans, or 2 (14.5 ounce) cans of drained green beans. When using canned green beans, you don’t need to cook them first. If you’re using fresh or frozen green beans, you’ll need to cook them until crisp-tender before adding them to the casserole. This takes about 5 minutes in the microwave for frozen green beans, or about 8 minutes in the microwave for fresh green beans.​​​​​​​

How to Make Easy Green Bean Casserole

Truly, one of the easiest green bean casseroles that you’ll ever make! It’s no wonder that this side dish has been a popular choice on American tables for over 60 years. It’s simple, convenient, and delicious!

Ingredients

• Green beans (fresh, frozen or canned)
• Condensed cream of mushroom soup
• Milk
• Soy sauce
• Black pepper
• French fried onions

Step 1: Cook Green Beans

Place the green beans in a microwave-safe dish, add a splash of water, cover, and cook in the microwave until crisp-tender. This will take about 5 minutes. Drain the liquid from the green beans.

Step 2: Add Remaining Ingredients

Stir in the condensed soup, milk, soy sauce, pepper, and half of the fried onions until everything is completely combined.

Step 3: Transfer to Baking Dish

Spread the green bean mixture in a 1½-quart baking dish.

Step 4: Bake

Bake, uncovered, in a 350 degree F oven for 25 minutes. Add the remaining fried onions on top.

Return the dish to the oven for about 5 more minutes, just to get the onions nice and toasty.

Make Ahead

Whether you’re preparing a big Thanksgiving feast, or just trying to get a head-start on tonight’s supper, this convenient side dish is a great recipe to make ahead. The green bean casserole can be assembled up to 2 days in advance. Just prepare as directed, but leave off the remaining fried onions that go on top at the end. Cover with foil and refrigerate until ready to bake.

When you’re ready to bake the casserole, allow the dish to sit on the counter at room temperature for at least 30 minutes. Bake according to the recipe instructions, adding a few extra minutes to the cooking time if the casserole is really cold when it goes into the oven.

Storage

Leftover green bean casserole will keep in an airtight container in the refrigerator for 3-4 days, although the onions on top tend to get soggy as it sits. You can freeze the casserole tightly wrapped for up to 3 months, but again — the onions on top may become soggy as it thaws.

To reheat the casserole, microwave individual servings for 30-60 seconds. If you’re reheating a larger dish, cover with foil and warm in a 325 degree F oven just until heated through — about 15-20 minutes.

Variations

• Swap out the frozen French-cut green beans and use 4 cups of frozen cut green beans, 4 cups of cut fresh green beans, or 2 (14.5 ounce) cans canned green beans (drained). If using frozen or fresh green beans, cook in the microwave until crisp-tender (about 5 minutes for frozen or 8 minutes for fresh).
• Instead of the cream of mushroom soup, use a different flavor of condensed soup. Cream of chicken or cream of celery would both be good in this recipe.
• Add cooked, chopped bacon to the green bean mixture, or sprinkle cooked bacon on top of the dish during the final few minutes to get nice and crispy.
• Sauté sliced fresh mushrooms and stir them into the green bean casserole before baking.
• Add 1 cup of grated cheese to the casserole before baking. Sharp cheddar cheese would be perfect!
• To serve a larger crowd, double all of the ingredients and bake the casserole in a 3-quart dish. This larger casserole will serve about 12 people. If you need to serve 20 people, I recommend preparing two large casseroles (3 quarts each), which will require 4 times as many ingredients.
