What is Green Bean Casserole?
Green bean casserole is a traditional American dish that typically features cooked green beans in a creamy mushroom sauce, all topped with crispy fried onions. First introduced in the 1950s by Campbell’s Soup Company, it was designed to be an easy, budget-friendly meal using common pantry ingredients. Over the years, it has evolved into a beloved comfort food, often served during Thanksgiving, Christmas, and other festive celebrations. Let’s dive into the essential ingredients and step-by-step instructions to make this easy and satisfying green bean casserole.
Ingredients List for Green Bean Casserole
Here are the ingredients you’ll need to create the classic version of green bean casserole:
- 4 cups of green beans (fresh, canned, or frozen)
- 1 can (10.5 ounces) of condensed cream of mushroom soup
- ½ cup of milk (preferably whole or 2% for creaminess)
- 1 teaspoon of soy sauce (optional, for added depth of flavor)
- ¼ teaspoon of black pepper (or to taste)
- 1 can (6 ounces) of crispy fried onions (like French’s® or a similar brand)
These ingredients form the base of your green bean casserole, but there are plenty of ways to customize it depending on your preferences. Let’s take a closer look at some possible variations and substitutions you can consider.
Substitutions and Variations
If you want to add your own twist to the classic green bean casserole, there are plenty of options to explore! Here are some popular substitutions and variations:
1. Green Beans:
- Fresh Green Beans: Fresh green beans offer a crisp texture and vibrant color. Simply blanch them in boiling water for 3-5 minutes before using in the recipe.
- Frozen Green Beans: A convenient option that requires no prep. Just thaw and drain them before adding to the casserole.
- Canned Green Beans: The most traditional choice, canned green beans are soft and work well with the creamy sauce. Drain them thoroughly before using.
2. Cream of Mushroom Soup:
- Cream of Chicken Soup: Swap out the mushroom soup for cream of chicken if you prefer a slightly different flavor.
- Cream of Celery Soup: This can be used for a lighter, milder taste.
- Homemade Sauce: For a from-scratch option, you can make your own creamy sauce using milk, butter, flour, and sautéed mushrooms.
3. Fried Onions:
- Panko Bread Crumbs: For a lighter topping, replace the fried onions with toasted panko bread crumbs mixed with melted butter.
- Cheese: Adding shredded cheddar or parmesan on top gives the casserole an extra layer of richness.
- Bacon Crumbles: Mix in cooked, crumbled bacon for a smoky, savory flavor.
With these substitutions and variations, you can easily customize the dish to fit your tastes or dietary preferences!
Step-by-Step Cooking Instructions

1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This temperature ensures that your casserole will cook evenly without burning the onions on top.
2. Prepare the Green Beans:
If you’re using fresh green beans, trim the ends and blanch them in boiling water for about 3-5 minutes. If you’re using frozen green beans, thaw them beforehand, and if using canned green beans, drain them well to remove excess liquid.
3. Mix the Sauce:
In a large mixing bowl, combine the condensed cream of mushroom soup, milk, soy sauce (if using), and black pepper. Whisk these ingredients together until smooth and well-blended.
4. Combine with Green Beans:
Add the prepared green beans to the sauce mixture and gently toss until the green beans are well-coated with the creamy sauce.
5. Assemble the Casserole:
Transfer the green bean mixture to a 9x13-inch baking dish, spreading it out in an even layer. Sprinkle half of the crispy fried onions over the top of the casserole.
6. Bake the Casserole:
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the casserole is bubbly around the edges.
7. Add the Final Topping:
Remove the casserole from the oven, sprinkle the remaining crispy fried onions evenly over the top, and return it to the oven. Bake for an additional 5-10 minutes, or until the onions are golden brown and crispy.
8. Let it Rest:
After baking, allow the casserole to rest for a few minutes before serving. This will help the dish set and make it easier to serve.
How to Cook Green Bean Casserole: A Step-by-Step Guide
To recap, here’s a quick step-by-step guide for cooking green bean casserole:
- Preheat the oven to 350°F (175°C).
- Prepare the green beans (blanch, thaw, or drain).
- Mix the sauce ingredients (soup, milk, soy sauce, pepper).
- Combine the green beans and sauce mixture.
- Transfer to a baking dish and top with crispy fried onions.
- Bake for 25-30 minutes until bubbly.
- Add more onions and bake for another 5-10 minutes.
- Let the casserole rest before serving.
Following these steps will ensure that your green bean casserole turns out perfectly every time.
Common Mistakes to Avoid
While green bean casserole is a fairly straightforward dish, there are a few common mistakes to watch out for:
- Overcooking the Green Beans: If you’re using fresh green beans, be careful not to over-blanch them. They should be tender-crisp, not mushy.
- Skipping the Drain on Canned Beans: Always drain canned green beans thoroughly. Excess liquid can make your casserole too watery.
- Soggy Topping: Add the crispy fried onions in stages to avoid them getting soggy. Bake with half the onions first, then add the rest toward the end for a crunchy finish.
Avoiding these mistakes will ensure that your casserole has the perfect texture and flavor.
