What Is Green Bean Casserole?
Green Bean Casserole is a classic American dish that dates back to the 1950s. It was originally created by Dorcas Reilly for Campbell's Soup Company, using simple ingredients like green beans, cream of mushroom soup, and fried onions. The dish is a delightful combination of creamy, savory green beans in a mushroom-based sauce, topped with crispy fried onions that add a perfect crunch to every bite. It’s easy to prepare and packs all the comfort and warmth you’d expect from a holiday favorite.
Ingredients List for Green Bean Casserole
This recipe requires just a few basic ingredients, most of which you might already have in your pantry:
- Fresh or Frozen Green Beans: 1½ lbs. Fresh green beans give a slightly firmer texture, but frozen can also be used if you're short on time.
- Cream of Mushroom Soup: 1 can (10.5 oz). This is the foundation of the creamy sauce. You can use low-sodium or reduced-fat versions if you prefer.
- Milk: ¾ cup. This helps to thin the soup, making a smooth sauce.
- Soy Sauce: 1 tablespoon. This adds a savory depth to the casserole.
- Black Pepper: ½ teaspoon, or to taste.
- Garlic Powder: ½ teaspoon, for an extra layer of flavor.
- Crispy Fried Onions: 1 can (6 oz), divided. These crunchy onions are essential to the classic green bean casserole and provide that irresistible crispy topping.
Substitutions and Variations
You can easily tweak this classic recipe to suit your dietary needs or flavor preferences. Here are some substitution ideas:
- Vegetarian/Vegan Version: Use a dairy-free cream of mushroom soup, almond milk or other plant-based milk, and vegan fried onions. Ensure that your soup is labeled vegan-friendly, as many mushroom soups contain dairy.
- Healthier Option: Opt for low-fat cream of mushroom soup and unsweetened almond milk for a lighter version of this dish.
- Gluten-Free: Make sure to use a gluten-free cream of mushroom soup and gluten-free fried onions.
- Extra Flavor: Add grated cheese (such as sharp cheddar or Parmesan) to the mixture for an even richer, creamier casserole.
- Bacon: For a smoky twist, sprinkle in some cooked, crumbled bacon into the casserole before baking.
- Mushroom Lovers: Sauté fresh mushrooms and add them to the casserole for extra earthiness and texture.
Step-by-Step Cooking Instructions

Follow these simple steps for a flawless green bean casserole:
- Preheat the Oven: Start by preheating your oven to 350°F (175°C).
- Prepare the Green Beans:
- If using fresh green beans, trim the ends and cut them into bite-sized pieces. Blanch them by boiling them in salted water for about 5 minutes, then drain and transfer them to an ice water bath to stop the cooking. Drain again and pat them dry.
- If using frozen green beans, make sure they are fully thawed and patted dry to remove any excess moisture.
- Mix the Sauce: In a large mixing bowl, whisk together the cream of mushroom soup, milk, soy sauce, black pepper, and garlic powder until well-combined and smooth.
- Assemble the Casserole:
- Add the blanched or thawed green beans to the sauce mixture, and stir until the beans are evenly coated.
- Stir in half of the crispy fried onions into the mixture. This will add some crunch throughout the casserole.
- Bake the Casserole: Transfer the green bean mixture into a greased 9x13-inch baking dish and spread it evenly. Bake uncovered for about 25 minutes until the sauce is bubbling and the beans are hot.
- Add the Crispy Onion Topping: After 25 minutes, remove the casserole from the oven, sprinkle the remaining crispy fried onions on top, and return it to the oven. Bake for another 5-10 minutes until the onions are golden and crispy.
- Serve: Once the casserole is done, let it cool slightly before serving. Enjoy this creamy, crunchy, and comforting side dish!

Common Mistakes to Avoid
- Not Blanching Fresh Green Beans: If you're using fresh green beans, don't skip the blanching step! This helps to soften the beans and ensures they cook evenly in the oven.
- Too Much Liquid: Be careful not to add too much liquid, or your casserole will end up soupy. Stick to the measurements for the milk and cream of mushroom soup to achieve the perfect creamy consistency.
- Overbaking the Fried Onions: Keep an eye on the crispy fried onions when you add them for the final bake. They can burn quickly, so be sure to bake them just until golden.
- Not Seasoning Properly: While the cream of mushroom soup and fried onions provide plenty of flavor, don’t forget to add additional seasoning. Taste your sauce and adjust the salt and pepper as needed.
