Campbells Green Bean Casserole Ingredients

Step‑by‑Step Instructions for Campbells Green Bean Casserole
Step 1: Preheat Your Cooking Device
Begin by preheating your oven or air fryer to 350°F. This temperature will ensure that your Campbells Green Bean Casserole cooks evenly and achieves that delightful creamy texture. While your appliance warms up, gather your ingredients and a 9×9 casserole dish, ready to create this comforting side dish.
Step 2: Prepare the Casserole Dish
Spray the 9×9 casserole dish with non-stick cooking spray, ensuring an even coating. This step is crucial to prevent the casserole from sticking as it bakes or air fries. Preparing the dish in advance will help make cleanup easier, allowing you to focus on the delicious flavors of the Campbells Green Bean Casserole.
Step 3: Prepare the Green Beans
If you’re using fresh green beans, rinse them under cold water, trim the ends, and blanch them in boiling water for 2 minutes. This quick blanching helps preserve their bright color and crispness. If using canned green beans, make sure to drain them well. After prepping your beans, set them aside while you mix the creamy base.
Step 4: Mix the Creamy Base
In a large mixing bowl, combine the condensed cream of mushroom soup, milk, and soy sauce. Stir the mixture vigorously until it’s smooth and free of lumps. This creamy base is what makes the Campbells Green Bean Casserole so indulgent and comforting. Take a moment to ensure your ingredients are well blended before adding the vegetables.
Step 5: Combine Ingredients
Add the prepared green beans and 2/3 of the crispy French fried onions to the soup mixture. Gently stir to combine everything, ensuring the beans are well coated with the creamy sauce. This mixture is going to become the heart of your casserole, so be careful not to break the beans as you blend.
Step 6: Pour into Casserole Dish
Carefully pour the green bean mixture into the prepared casserole dish, spreading it out evenly. This ensures even cooking and crispy topping throughout the whole dish. Make sure to wear oven mitts if your dish is warm. Next, it’s time to cook this classic Campbells Green Bean Casserole to perfection.
Step 7: Cook in Air Fryer
If you choose the air fryer method, cook the casserole for 10 minutes at 350°F. After 10 minutes, carefully stir the casserole to ensure even cooking. Top it with the remaining crispy French fried onions and cook for an additional 2-3 minutes or until the onions are golden brown and crunchy.
Step 8: Bake in Oven
For the oven option, place the casserole in the preheated oven and bake for 25 minutes. After that, take a moment to stir the casserole gently. Sprinkle the remaining crispy French fried onions on top and bake for an additional 5 minutes until the onions are golden brown and crispy, elevating the Campbells Green Bean Casserole to a whole new level of deliciousness.

Make Ahead Options
These Campbells Green Bean Casserole preparations are perfect for busy home cooks looking to simplify their holiday meal planning! You can assemble the entire casserole up to 24 hours in advance by combining the creamy base with green beans and 2/3 of the crispy onions, then refrigerating it tightly covered to maintain freshness. This not only saves time but allows the flavors to meld beautifully. When you’re ready to cook, simply sprinkle the remaining onions on top and either air fry or bake as directed, adding a few extra minutes to the cooking time if it’s been chilled. Trust me, this casserole will taste just as delicious when prepped ahead!
