How to Make Campbells Green Bean Casserole
-
Prepare Green Beans: Start by if using frozen green beans, fully thaw and drain them. For fresh beans, trim and cut into 2-inch pieces, then blanch in salted boiling water until tender-crisp before draining. Canned beans just need a good drain!
-
Preheat Oven: Set your oven temperature to a cozy 350°F. This helps get the casserole bubbling perfectly while it bakes.
-
Measure Fried Onions: Divide your crispy fried onions into two portions: keep about 2/3 cup for mixing into the casserole and save the extra 1/3 cup for that irresistible crispy topping.
-
Mix Sauce: Grab a large mixing bowl and whisk together the condensed cream of mushroom soup, milk, and soy sauce. Blend until everything is smooth and well combined for a creamy base.
-
Combine Ingredients: To the soup mixture, gently fold in your drained green beans, the 2/3 cup of fried onions, and sprinkle in the black pepper. Make sure those green beans are lovely and coated!
-
Transfer to Baking Dish: Pour the green bean mixture into a 9×9-inch baking dish, spreading it into an even layer. Pop it in the oven and bake for 25 minutes.
-
Stir & Top: Once done, carefully remove the casserole and give it a gentle stir to mix in the bubbling sauce. Sprinkle on the reserved 1/3 cup of fried onions for that delightful crunch.
-
Final Bake: Return your casserole to the oven for an additional 5 minutes or until the onions are a beautiful golden brown and the dish is bubbling gently.
Optional: Serve with a sprinkle of fresh parsley for an added pop of color!

Campbells Green Bean Casserole Recipe FAQs
What type of green beans should I use for this recipe?
You can absolutely use fresh, frozen, or canned green beans. Fresh green beans provide the best texture and flavor, so I recommend trimming and cutting them into 2-inch pieces, then blanching them briefly. If you’re using frozen beans, just make sure to thaw and drain them completely. Canned beans are the simplest option—just drain and they’re ready to go!
How should I store leftovers of the Campbells Green Bean Casserole?
To keep your delicious casserole fresh, store the leftovers in an airtight container in the refrigerator. They’ll stay good for up to 3 days. Just reheat in the oven at 350°F for about 25-30 minutes or until warmed through, covering with foil to retain moisture.
Can I freeze Campbells Green Bean Casserole?
Yes, it’s freezer-friendly! For best results, freeze the casserole unbaked in a tightly sealed container. You can keep it in the freezer for up to 2 months. When you’re ready to bake it, simply thaw it overnight in the fridge, then bake as directed. This way, you’ll have a comfort dish ready when the cravings hit!
What should I do if my casserole looks dry after baking?
If you find your casserole is a bit dry, don’t worry! First, ensure the top isn’t overbaking by keeping an eye on it during the last few minutes. If that happens, you can stir in a splash of milk or some broth to moisten it right before serving. It’s all about getting that creamy, delightful texture back!
Are there any dietary considerations for this recipe?
Absolutely! If you’re cooking for someone with dairy allergies, you can easily substitute the milk with almond milk or a similar non-dairy alternative. If you have gluten sensitivities or need an alternative, look for gluten-free crispy fried onions. Always check ingredient labels to ensure they align with dietary needs!
How can I enhance the flavor of the casserole?
Great question! For an extra layer of depth, consider adding sautéed garlic or onion to the sauce for a flavor boost. You can also sprinkle some grated cheese, like cheddar or Parmesan, over the fried onions before the final bake. This adds a delicious, gooey richness that pairs wonderfully with the green beans!
