Step‑by‑Step Instructions for Campbells Green Bean Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial for ensuring that your Campbell’s Green Bean Casserole bakes evenly and reaches a delightful bubbly state. While the oven warms up, gather all your ingredients in the kitchen to streamline the cooking process.
Step 2: Prepare the Green Beans
Depending on your choice of green beans, rinse and drain canned beans, thaw and pat dry frozen beans, or trim and cut fresh beans into pieces. If using fresh, blanch them in boiling water for 3-4 minutes until just tender but still crisp. Drain and set aside for assembling the casserole.
Step 3: Mix the Sauce
In a large mixing bowl, whisk together one can of condensed cream of mushroom soup, about one cup of whole milk, and a splash of soy sauce until the mixture is smooth and creamy. This luscious sauce will be the heart of your Campbell’s Green Bean Casserole, adding depth and flavor that meld beautifully with the green beans.
Step 4: Combine Ingredients
Gently fold the prepared green beans into the creamy sauce while adding 2/3 cup of crispy fried onions for an added crunch. Stir carefully to avoid breaking the onions, ensuring they maintain their texture. This delightful blend is where comfort meets creativity, creating the essence of your casserole.
Step 5: Assemble the Casserole
Spread the green bean mixture evenly in a greased 9×9-inch baking dish. Make sure it fills the dish to create a beautiful, thick layer that will bake evenly in the oven. Ensuring an even spread helps achieve the perfect texture and prevents any area from baking too quickly.
Step 6: Bake the Casserole
Place the baking dish in your preheated oven and bake for about 25 minutes. Keep an eye on the casserole; it should be bubbling at the edges when it’s ready. This is the moment when your kitchen fills with the inviting aroma of comfort food.
Step 7: Add the Finishing Touch
After 25 minutes, take the casserole out of the oven and give it a gentle stir. Top it with the remaining crispy fried onions, spreading them evenly. Return it to the oven for an additional 5 minutes, allowing the onions to get golden brown and crispy, adding that delightful crunch you crave in your Campbell’s Green Bean Casserole.

Make Ahead Options
These Campbell’s Green Bean Casserole is perfect for busy home cooks looking to save time! You can prepare the green bean mixture up to 24 hours ahead by combining the rinsed canned or thawed frozen beans with the creamy sauce (soup, milk, and soy sauce), and folding in 2/3 cup of crispy fried onions. Simply cover and refrigerate the mixture, ensuring it remains fresh and delicious. When you’re ready to serve, spread it into a greased baking dish and bake at 350°F for about 25 minutes until bubbly. Don’t forget to add the remaining crispy onions on top and bake for an extra 5 minutes to restore that irresistible crunch! Enjoy the convenience of having a comforting dish ready with minimal effort.

Campbell’s Green Bean Casserole Recipe FAQs
How do I select the best green beans for this casserole?
Absolutely! For canned green beans, look for varieties without added salt for a healthier option; just rinse and drain them thoroughly. When using frozen green beans, ensure they are completely thawed and patted dry to maintain their texture during baking. If opting for fresh, select bright green, firm beans without any dark spots. Trim the ends and cut them into bite-sized pieces before blanching in boiling water for 3-4 minutes to keep them nice and crisp.
What is the best way to store leftovers of Campbell’s Green Bean Casserole?
Very! To store leftovers, simply place them in a covered dish and refrigerate for up to 4 days. The great news is that this casserole often tastes even better the next day as the flavors meld together beautifully. Just reheat it in the oven at 350°F until heated through, and enjoy!
Can I freeze Campbell’s Green Bean Casserole?
Absolutely! If you’d like to freeze your casserole, I recommend doing so without the crispy fried onions, which can lose their crunch. Transfer the cooled casserole to an airtight container or freezer bag and freeze it for up to 3 months. To prepare, thaw it in the refrigerator overnight before reheating in the oven at 350°F for about 20-25 minutes. Add a fresh layer of crispy onions just before the end to recreate that delightful crunch.
Why did my casserole come out mushy, and how can I avoid this?
Great question! A mushy casserole can occur if fresh green beans aren’t blanched properly or if everything is mixed too vigorously. Make sure to blanch fresh beans just until they’re tender but still bright green for 3-4 minutes. Additionally, when folding the green beans into the sauce, do so gently to maintain their integrity. Avoid overmixing to keep the texture enjoyable and not mushy.
Is this recipe safe for those with allergies?
Yes, but always exercise caution! The Campbell’s Green Bean Casserole contains common allergens such as dairy (from the milk and soup) and is not gluten-free due to the soup and soy sauce. For those with soy allergies, you can substitute coconut aminos or omit it altogether. I often make the casserole with dairy-free milk and a dairy-free cream soup if needed, but be sure to read labels carefully for any variations you choose!
Can I prepare this casserole in advance?
Absolutely! This recipe shines when made ahead. Assemble the casserole a day in advance and cover it tightly with plastic wrap or aluminum foil. Store it in the refrigerator and bake it right before serving, which allows the flavors to develop beautifully. This make-ahead magic lets you focus on spending quality time with your loved ones during the holiday hustle!
