What is a Traditional Green Bean Casserole?
A traditional Green Bean Casserole is a baked vegetable dish that features green beans as the main ingredient. It’s paired with a rich and savory mushroom-based sauce and topped with fried onions for a crispy finish. This dish was first created by Campbell’s Soup in the 1950s, using their Cream of Mushroom Soup as a key component. Since then, it’s become a staple comfort food and a must-have during the holiday season. The beauty of the recipe lies in its simplicity, combining just a few basic ingredients to make a mouth-watering dish that will have everyone asking for seconds.
Ingredients List for Traditional Green Bean Casserole
To create this delightful dish, you’ll need the following ingredients:
- Fresh or canned green beans – About 4 cups (or 2 cans) of green beans. Fresh beans are ideal, but canned or frozen will work just as well.
- Cream of Mushroom Soup – 1 can (about 10.5 ounces). This forms the creamy base of the casserole.
- Milk – ¾ cup of milk to help thin the soup and make the sauce.
- Soy Sauce – 1 teaspoon for added umami flavor.
- Black Pepper – ¼ teaspoon to season the casserole.
- Fried Onions – About 1½ cups of crispy fried onions. You’ll use some in the casserole and the rest as a topping.
This is the basic, traditional ingredient list, but feel free to add other items to customize it to your taste! We’ll cover some substitutions and variations in a bit.
Substitutions and Variations
Want to put your own twist on this classic? Here are some easy substitutions and variations that can take your Green Bean Casserole to the next level:
- Use Fresh Green Beans: If you’re using fresh green beans, boil or steam them until tender before adding them to the casserole. This gives the dish a fresher taste and firmer texture.
- Swap out Cream of Mushroom Soup: Not a fan of mushrooms? You can substitute it with Cream of Chicken or Cream of Celery soup.
- Make It Vegan: Use a plant-based cream soup and non-dairy milk for a vegan-friendly version. You can also find vegan fried onions at most grocery stores.
- Add Cheese: For an extra indulgent casserole, mix in 1 cup of shredded cheddar or mozzarella cheese.
- Include Mushrooms: Boost the mushroom flavor by adding fresh or sautéed mushrooms along with the green beans.
Step-by-Step Cooking Instructions

Preparing the perfect Green Bean Casserole is incredibly simple. Follow these steps to get a flavorful dish that’s creamy, crispy, and absolutely delicious.
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). This will ensure it’s hot and ready when your casserole is assembled.
- Prepare the Green Beans: If you're using fresh green beans, trim the ends and cut them into bite-sized pieces. Blanch them by boiling in salted water for about 4-5 minutes, then drain and set aside. If you're using canned or frozen green beans, simply drain them (for canned) or thaw and drain (for frozen).
- Make the Sauce: In a mixing bowl, combine the Cream of Mushroom Soup, milk, soy sauce, and black pepper. Stir until smooth and well mixed. This is the creamy base of your casserole.
- Combine the Ingredients: In a large bowl, toss the cooked or drained green beans with about half of the fried onions and the prepared sauce mixture. Make sure everything is evenly coated with the sauce.
- Transfer to Casserole Dish: Pour the green bean mixture into a lightly greased 9x13-inch casserole dish and spread it out evenly.
- Bake the Casserole: Place the dish in the preheated oven and bake for about 25 minutes or until bubbly around the edges.
- Add the Topping: After 25 minutes, remove the casserole from the oven and sprinkle the remaining fried onions on top. Return the dish to the oven and bake for another 5-10 minutes, or until the onions are golden brown and crispy.
- Cool and Serve: Let the casserole cool for a few minutes before serving to allow it to set.

- Preheat Oven: 350°F (175°C).

Common Mistakes to Avoid
Even a simple recipe like Green Bean Casserole can have its pitfalls. Avoid these common mistakes to ensure your dish turns out perfect every time.
- Undercooking Fresh Beans: If using fresh beans, make sure to cook them until tender before adding them to the casserole. Undercooked beans can be too crunchy.
- Using Too Much Milk: Stick to the recipe measurements. Adding too much liquid will make the casserole soupy.
- Overbaking: Keep an eye on the casserole as it bakes. Overbaking can dry it out or burn the onion topping.
- Skipping the Blanching Step: If using fresh beans, always blanch them first. This step softens the beans while preserving their bright green color.
Serving and Presentation Tips
Green Bean Casserole may be a simple dish, but that doesn’t mean you can’t elevate its presentation. Here are a few serving and presentation tips:
- Use a White Casserole Dish: A white or cream-colored dish allows the vibrant green of the beans and golden fried onions to pop.
- Garnish with Fresh Herbs: Sprinkle some chopped parsley or thyme over the top for a touch of freshness and color.
- Serve in Individual Ramekins: For a more elegant presentation, divide the casserole into small ramekins, making it a personal serving for each guest.
How to Serve Green Bean Casserole
Green Bean Casserole is best served as a side dish, but it can also be a light main course if paired with a side salad or warm bread. It pairs especially well with roasted meats like turkey, chicken, or ham. Don’t forget to place it on the table while it’s still warm to enjoy the crispiness of the onion topping!
Presentation Ideas for Green Bean Casserole
To take your Green Bean Casserole up a notch, consider the following presentation ideas:
- Layer the Beans Neatly: Before adding the sauce, line the green beans up in the dish for a more structured look.
- Use an Oven-to-Table Dish: If you have a beautiful baking dish that doubles as a serving dish, bake and serve your casserole in it to reduce cleanup and make an elegant statement.
Green Bean Casserole Recipe Tips
- Make It Ahead: Prepare the casserole up to the baking step the day before. Cover and refrigerate, then bake just before serving.
- Keep It Crispy: For extra crispy onions, only add them during the final 10 minutes of baking.
- Double the Recipe: Feeding a crowd? Double the recipe and bake it in a larger dish.
- Spice It Up: Add a pinch of cayenne pepper or red pepper flakes for a subtle kick.
