Key ingredients for Campbells green bean casserole
Cooked green beans (4 cups)
Tender cooked green beans are the base of the casserole, and their fresh taste balances the creamy sauce. Freshly cooked or good frozen beans give the best results.
Campbell’s cream of mushroom soup (1 can, 10.5 oz)
The soup brings the rich, savory flavor and the creamy texture that makes this casserole so comforting.
Milk (1/2 cup)
Milk loosens the soup so the sauce is smooth all the way through, and it helps the flavors come together.
French’s fried onions (1 1/3 cups)
The crispy onions add crunch and flavor against the creamy filling. They are the classic topping for this casserole.
Soy sauce (1/2 teaspoon)
Just a little deepens the savory flavor and adds a hint of umami without taking over.
Black pepper (1/4 teaspoon)
Adds warmth and balances the richness of the casserole.

Variations of Campbells green bean casserole
Classic twist
Add sautéed mushrooms or garlic for more aroma. A sprinkle of grated cheese, such as cheddar or Parmesan, adds flavor and makes the casserole richer.
Healthier options
To lighten it up, replace the Campbell’s soup with a homemade cream of mushroom made with low-fat milk and fresh mushrooms. Fresh green beans in place of canned add more nutrition. A handful of chopped almonds or walnuts brings healthy fats and crunch.
Seasonal variations
Change the casserole with the seasons. In the fall, roasted butternut squash adds a sweet, earthy flavor that goes well with green beans. In the winter, cooked kale or spinach adds color and extra nutrition.

Cooking tips and notes
Getting it right
Preheat the oven to the right temperature so the casserole bakes evenly. Fresh green beans in place of canned give brighter color and more bite. For a creamier casserole, add a little more milk.
Timing
Watch the baking time. The first 30 minutes let the flavors come together, and the last 10 minutes with the fried onions on top give the golden, crispy finish. The recipe doubles easily for a larger gathering; a bigger casserole may need a little more time in the oven.
Make-ahead tips
You can assemble the casserole a day in advance. Cover it tightly and refrigerate. When you bake it, add a few extra minutes so it heats through. Making it ahead also gives the flavors more time to develop.
Serving suggestions for Campbells green bean casserole
Pairing with main dishes
It goes with roasted turkey or chicken, which is why it shows up at so many holiday dinners. It also works next to grilled steak or pork chops, where the creamy, crunchy casserole is a good contrast to the meat.
Adding a salad
For a balanced meal, serve a fresh salad alongside. A crisp garden salad with a light vinaigrette cuts through the richness. A warm spinach salad with bacon and goat cheese is another good match.
Good for potlucks
It is easy to make, most people know and like it, and it can be made ahead, so you spend less time in the kitchen and more with your friends and family. Bring a serving spoon.
