What Is Green Bean Casserole?
Green bean casserole is a classic American dish made primarily of green beans, a creamy mushroom-based sauce, and crispy fried onions. First introduced by Campbell’s Soup Company in the 1950s, it quickly gained popularity for its simplicity and rich flavor. The recipe has remained a favorite for generations because of how easily it can be made with just a few ingredients that most people already have in their pantry.
With just the right balance of creaminess and crunch, green bean casserole is often found on Thanksgiving tables but can be enjoyed year-round. Let’s look at what you’ll need to get started!
Ingredients List for Green Bean Casserole
Before you start cooking, make sure you have all the ingredients ready. Here’s what you’ll need for a classic green bean casserole:
- Green beans – 4 cups (fresh, frozen, or canned)
- Cream of mushroom soup – 1 can (10.5 ounces)
- Milk – ¾ cup
- Soy sauce – 1 teaspoon
- Black pepper – ½ teaspoon
- Garlic powder – ½ teaspoon
- Fried onions – 1 ½ cups (divided)
These ingredients are enough to make a basic version of the casserole that serves about 6 people. Now, let’s take a look at some variations and substitutions if you want to switch things up or accommodate dietary needs.
Substitutions and Variations
While the traditional green bean casserole recipe is a classic, it’s versatile enough for some creative spins. Here are some popular substitutions and variations:
- Use fresh green beans: While canned or frozen green beans are convenient, using fresh beans gives the dish a crispier texture. Just blanch them in boiling water for 3-5 minutes, then cool them in ice water before adding them to the casserole.
- Swap out the cream of mushroom soup: Not a fan of mushrooms? You can substitute the cream of mushroom soup with cream of chicken, cream of celery, or even a homemade white sauce for a different flavor profile.
- Add cheese: If you're a cheese lover, sprinkle shredded cheddar or parmesan into the casserole before baking for an extra layer of flavor.
- Make it gluten-free: To make this dish gluten-free, use gluten-free fried onions and a gluten-free cream of mushroom soup. You can also make your own fried onion topping using gluten-free breadcrumbs.
- Vegan option: For a plant-based version, use a vegan cream of mushroom soup, unsweetened almond milk, and vegan fried onions.
With these simple swaps, you can easily customize the dish to fit your taste or dietary needs.
Step-by-Step Cooking Instructions

Now that we have the ingredients and possible substitutions in mind, let’s move on to the cooking process. Follow these steps to create the perfect green bean casserole.
1. Preheat the oven
Preheat your oven to 350°F (175°C) to get it ready for baking. This will ensure that the casserole bakes evenly and comes out hot and bubbly.
2. Prepare the green beans
If you’re using fresh or frozen green beans, blanch them first by boiling them for 3-5 minutes and then cooling them in ice water to stop the cooking process. Drain well. If using canned beans, simply drain and rinse them before adding to the recipe.
3. Mix the sauce
In a large mixing bowl, combine the cream of mushroom soup, milk, soy sauce, black pepper, and garlic powder. Stir until all ingredients are well incorporated and the sauce is smooth.
4. Combine the beans and sauce
Add the green beans to the bowl with the sauce and mix everything together until the beans are well coated.
5. Add half of the fried onions
Mix in half of the fried onions with the green bean mixture. This will add a bit of crunch inside the casserole while keeping the rest for the crispy topping.
6. Transfer to a casserole dish
Pour the green bean mixture into a lightly greased casserole dish, spreading it out evenly.
7. Bake the casserole
Bake the casserole uncovered for about 25 minutes, or until it’s heated through and bubbling around the edges.
8. Add the final topping
After the casserole has baked for 25 minutes, remove it from the oven and sprinkle the remaining fried onions over the top. Place it back in the oven and bake for another 5-10 minutes, or until the onions are golden brown.
9. Let it cool
Once the casserole is done baking, let it cool for about 5 minutes before serving. This will help the flavors meld together and make it easier to dish out.
How to Cook Green Bean Casserole: A Step-by-Step Guide
Cooking a green bean casserole is incredibly simple, even for beginners. Here's a quick summary to ensure you get it right every time:
- Preheat your oven to 350°F (175°C).
- Prepare the green beans by blanching fresh beans or draining canned beans.
- Mix the sauce – combine cream of mushroom soup, milk, soy sauce, black pepper, and garlic powder.
- Combine the green beans with the sauce and add half of the fried onions.
- Bake for 25 minutes.
- Top with the remaining fried onions and bake for an additional 5-10 minutes.
- Cool for 5 minutes before serving.
Simple as that! Now, let’s make sure you avoid some common mistakes when cooking this dish.
Common Mistakes to Avoid
While the recipe is fairly straightforward, here are a few common mistakes to keep in mind:
- Overcooking the green beans: Fresh green beans can turn mushy if overcooked, so if you're using them, be sure to blanch them just until tender-crisp.
- Too much liquid: Be mindful of how much milk you add to the sauce. Too much can make the casserole runny rather than creamy.
- Soggy topping: Add the fried onions only during the last few minutes of baking to keep them crispy. If you add them too early, they may become soggy.
- Skipping seasoning: The sauce needs seasoning to bring out the full flavor of the green beans and cream of mushroom soup. Don’t forget the soy sauce, black pepper, and garlic powder.
Now that you know what to avoid, let's move on to making your casserole look just as good as it tastes!
Serving and Presentation Tips
