Step‑by‑Step Instructions for Campbells Green Bean Casserole
Step 1: Preheat Your Oven or Air Fryer
Start by preheating your oven or air fryer to 350°F. This ensures that your Campbells Green Bean Casserole cooks evenly and thoroughly, giving you that delightful creamy and crunchy result. While your appliance is warming up, gather all your ingredients for a smoother cooking experience.
Step 2: Prepare Your Casserole Dish
Lightly spray a 9×9 casserole dish with cooking spray to prevent sticking and ensure easy serving. This small action makes a big difference when it comes to cleanup time. With your dish prepared, you’re ready to move on to the veggies that star in this classic recipe.
Step 3: Get Those Green Beans Ready
If you’re using fresh green beans, rinse, trim the ends, and blanch them in boiling water for about 2 minutes before draining. This quick blanching makes fresh beans tender while maintaining their vibrant green color. If using canned beans, simply drain them well to remove excess liquid and give them a quick rinse.
Step 4: Mix the Creamy Base
In a mixing bowl, combine the condensed cream of mushroom soup, milk, and soy sauce. Stir the mixture until smooth and well blended, creating the creamy base for your casserole. This step is crucial for ensuring that each bite of your Campbells Green Bean Casserole is rich and flavorful.
Step 5: Combine the Ingredients
Carefully fold the prepared green beans into the creamy soup mixture, ensuring they are evenly coated. Next, add in about 2/3 of the crispy fried onions and season with a generous sprinkle of pepper. The combination of flavors and textures here is what makes this dish a beloved favorite.
Step 6: Transfer to the Casserole Dish
Pour the green bean mixture into the prepared casserole dish, spreading it evenly with a spatula. This ensures that every corner of the dish is filled with that delicious creamy goodness. As you spread, your kitchen will start to smell wonderful, hinting at the tasty meal to come.
Step 7: Air Fryer Cooking Time
If you’re using an air fryer, place the casserole in for 10 minutes. After this initial cooking time, stir the mixture and sprinkle the remaining crispy fried onions on top. Cook for an additional 2-3 minutes, until the onions turn golden brown and crispy, adding that perfect crunch to the casserole.
Step 8: Oven Cooking Time
For those using the oven, bake your casserole for 25 minutes. Once the time is up, stir gently and add the remaining crispy fried onions. Bake for an extra 5 minutes or until the onions are golden and the casserole is bubbling at the edges. Your Campbells Green Bean Casserole is now ready to serve!
