Step‑by‑Step Instructions for Campbells Green Bean Casserole
Step 1: Prepare Beans
If you’re using fresh green beans, start by trimming the ends and blanching them in boiling salted water for 3-4 minutes until bright green and slightly tender. Drain and set aside to cool. For frozen beans, simply thaw and drain them thoroughly. If opting for canned beans, make sure to drain them well to avoid excess moisture.
Step 2: Preheat Oven
Next, preheat your oven to 350°F (175°C). This temperature ensures that your Campbells Green Bean Casserole bakes evenly, allowing the flavors to meld beautifully while creating that ideal creamy texture. If you’re using an air fryer, prepare it to the same temperature to achieve a quick, crispy finish.
Step 3: Mix Base
In a large mixing bowl, whisk together one can of condensed cream of mushroom soup, preferably Campbell’s for optimal flavor, with ¾ cup of whole milk and 1 tablespoon of soy sauce. This will create a smooth and creamy sauce that serves as the flavorful base for your casserole. Make sure to blend well to eliminate any lumps, ensuring a silky consistency.
Step 4: Combine Ingredients
Once your sauce is ready, gently fold in the prepared green beans, 2/3 cup of crispy fried onions, and a sprinkle of ground black pepper to the mixture. Stir carefully to coat the beans thoroughly without overmixing, which could lead to mushy textures once baked. This is the heart of your Campbells Green Bean Casserole, so take your time!
Step 5: Bake First Layer
Transfer the green bean mixture to a greased 9×9-inch baking dish, spreading it evenly. Place the dish in the oven and bake for 25 minutes or until the mixture is bubbling and hot throughout. If using an air fryer, adjust the baking time to 10 minutes. Keep an eye on it; you want to see a little bubbling around the edges!
Step 6: Add Topping
After the initial baking, carefully remove the casserole from the oven. Stir it gently to ensure an even distribution of heat, then sprinkle the reserved crispy fried onions over the top. Return the dish to the oven for an additional 5 minutes, or just 2 minutes if cooking in an air fryer, until the onions are golden brown and crispy, adding that perfect crunch to your Campbells Green Bean Casserole.
