Step‑by‑Step Instructions for Campbells Green Bean Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F. If you’re using an air fryer for a quicker bake, prepare it according to the manufacturer’s instructions. Setting the proper temperature initially will ensure an even cook for your homemade Campbell’s Green Bean Casserole, resulting in the perfect creamy and crunchy blend when it’s done.
Step 2: Prepare the Green Beans
If you chose frozen green beans, make sure they are fully thawed, then drain any excess moisture. For fresh green beans, trim the ends and blanch them in salted boiling water for about 3-4 minutes until vibrant green, then drain thoroughly. This step is crucial to achieving that delightful texture in your green bean casserole.
Step 3: Mix the Soup Base
In a large mixing bowl, whisk together the cream of mushroom soup, milk, and soy sauce until the mixture is smooth and homogenous. This creamy base is the heart of your Campbell’s Green Bean Casserole. Ensure no lumps are present, as they can affect the overall consistency of your casserole when baked.
Step 4: Combine Ingredients
Gently fold in the prepared green beans along with 2/3 of the French fried onions and a sprinkle of black pepper. Make sure everything is evenly coated to distribute those delicious flavors throughout your casserole. The crunchy onions add texture and flavor that will elevate your dish to new heights.
Step 5: Transfer to Baking Dish
Pour the mixture into a 9×9-inch baking dish, spreading it evenly. This is essential for even cooking and bubbling. Place the dish in the preheated oven and allow it to bake for 25 minutes, or if using an air fryer, cook for about 10 minutes until the edges are bubbling and the top starts to set.
Step 6: Add Remaining Onions
After the initial baking, carefully stir the casserole to ensure even heating and then sprinkle the remaining 1/3 of the fried onions on top. This final touch adds that irresistible crunch. Return the baking dish to the oven for an additional 5 minutes, or until the onions are golden brown and crispy, creating a beautiful topping for your Campbell’s Green Bean Casserole.

Make Ahead Options
Preparing Campbell’s Green Bean Casserole ahead of time is a fantastic way to save you precious minutes during busy weeknights or festive gatherings! You can mix the creamy soup base, green beans, and onions up to 24 hours in advance; simply store the mixture in an airtight container in the refrigerator. If you opt for freezing, prepare the casserole without the fried onions, then wrap tightly and freeze for up to 3 months. To reheat, thaw overnight in the fridge and bake it at 350°F for about 30-35 minutes until bubbling. Adding the onions right before baking ensures they stay crispy and delicious. Enjoy your hassle-free, comforting meal that tastes just as great made ahead!

Campbells Green Bean Casserole Recipe FAQs
What type of green beans should I use for this casserole?
You can use canned, frozen, or fresh green beans depending on your preference. Canned green beans are convenient and ready to use, while frozen green beans retain their freshness. If you choose fresh, I suggest trimming and blanching them for just 3-4 minutes in salted boiling water before adding to your casserole for the best texture.
How do I store leftover Campbell’s Green Bean Casserole?
Once cooled, store any leftover casserole in an airtight container in the refrigerator. It’s best consumed within 4 days, preserving its creamy flavor and texture. When you’re ready to reheat, simply pop it in the oven at 350°F until warmed through—about 25-30 minutes works well.
Can I freeze Campbell’s Green Bean Casserole?
Absolutely! For freezing, I recommend making the casserole ahead of time without the onion topping and placing it in a freezer-safe container. It can be frozen for up to 3 months. When you’re ready to enjoy it, let it thaw in the fridge overnight, then bake it at 350°F until hot. Just remember to top with fresh fried onions before the final bake for that irresistible crunch!
What can I do if my casserole turns out too mushy?
If you find your casserole a bit mushy, next time try not to overcook the green beans—especially if using frozen or canned. Make sure to monitor the baking time closely and avoid stirring too much after baking, as this can break down the beans further. If you end up with a mushy casserole, consider adding a sprinkle of fresh parsley or croutons on top for extra texture!
Is this casserole suitable for vegetarians or those with allergies?
Yes, this Campbell’s Green Bean Casserole can easily be made vegetarian. Just use a non-dairy milk substitute and ensure your cream of mushroom soup is a vegetarian version. Additionally, check the label on the fried onions for any potential allergens like gluten or soy if that’s a concern for your household.
How can I customize this dish for dietary preferences?
You can make various adjustments! For a lighter version, consider using low-fat milk or a plant-based alternative.
