Ingredients Needed

The beauty of this green bean casserole recipe is that it uses simple ingredients that you probably already have or can easily find at the store. To make this dish, you will need fresh or frozen green beans, Campbell’s cream of mushroom soup, milk, soy sauce, black pepper, and crispy French fried onions.
These ingredients come together to create the familiar and much-loved flavor profile. Fresh green beans bring a bright, fresh taste and a bit of snap. If fresh green beans are not available, frozen ones work just as well and save time on preparation.
The cream of mushroom soup is key because it provides that creamy, savory base that holds the casserole together. Milk helps thin out the soup so that it spreads evenly over the beans and keeps the casserole moist. Soy sauce adds a subtle depth of umami flavor without overpowering the dish. Black pepper gives a gentle kick to balance the creaminess. Finally, the French fried onions on top give the casserole its iconic crispy topping, which adds a wonderful texture contrast.

Step-by-Step Cooking Instructions
Making Campbell’s green bean casserole is simple and straightforward. First, preheat your oven to 350 degrees Fahrenheit. This ensures the casserole will cook evenly once it goes into the oven.
If you are using fresh green beans, give them a quick boil or blanch for about five minutes. This softens them just enough without making them mushy. If you are using frozen green beans, make sure they are thawed and well-drained to avoid adding extra water to the casserole.
Next, in a large mixing bowl, combine the cream of mushroom soup, milk, soy sauce, and black pepper. Stir these ingredients well until you get a smooth and creamy mixture. The soy sauce is a secret touch that brings out the umami flavor in the soup, so don’t skip it.
Now add the green beans and half of the French fried onions to the soup mixture. Gently fold them in so that the beans are evenly coated. After that, transfer the whole mixture into a 1 and a half quart casserole dish and spread it out evenly.
Bake the casserole uncovered in your preheated oven for about 25 minutes. This allows the mixture to heat through and the flavors to meld. After the baking time, take the casserole out of the oven and sprinkle the remaining French fried onions evenly over the top.
This topping will crisp up and turn golden during the final bake. Put the casserole back into the oven for an additional five minutes to let the onions get perfectly crispy. Once done, take the casserole out and let it cool slightly before serving.
This step is important so the casserole sets and doesn’t spill when you scoop it onto plates. The final dish should be creamy with tender green beans and a crunchy onion topping. It is best enjoyed warm.

Tips for Customizing the Recipe

While Campbell’s original recipe is perfect as it is, there are many ways you can personalize the casserole to fit your preferences or dietary needs.
If you want a cheesier casserole, adding one cup of shredded cheddar or Parmesan cheese to the soup mixture creates a rich and gooey texture that pairs wonderfully with the green beans.
For those who prefer a healthier option, try using low-fat or reduced sodium cream of mushroom soup along with a milk alternative like almond or oat milk. This cuts down on calories and sodium without sacrificing flavor.
If you love extra crunch, consider mixing half of the French fried onions with toasted breadcrumbs or chopped nuts like pecans or walnuts. This will add a unique texture and taste to the topping.
You can also add extra vegetables or flavors such as sautéed mushrooms, diced onions, or even crispy bacon bits to elevate the dish. Adding fresh herbs like thyme or parsley right before serving brightens the flavor and gives the casserole a fresh note.
Lastly, if you want to make the casserole ahead of time, you can prepare it up to the point of baking and refrigerate it for a day. When you are ready to serve, just bake it as usual. This makes it easy for holiday cooking or busy weeknights.
