Campbells Green Bean Casserole Ingredients
For the Casserole
• Cream of Mushroom Soup – This provides the dish with its signature creaminess and flavor; other condensed soups like cream of celery can also work.
• Milk – Essential for thinning out the soup to create a deliciously creamy sauce; no substitutes are recommended.
• Soy Sauce – Adds umami depth to the flavor profile; Worcestershire sauce can be used as a unique substitute.
• Green Beans – The heart of the dish; opt for canned for convenience, or fresh/frozen for a homemade touch—just remember to blanch fresh beans for 2 minutes.
• Crispy French Fried Onions – These delightful, crunchy toppings are what make this dish irresistible; there aren’t any direct substitutes that provide the same texture.
• Pepper – A simple seasoning to enhance flavor; you won’t need added salt due to the sodium already in other ingredients.
Optional Additions
• Shredded Cheddar Cheese – For those who enjoy a cheesy twist, fold it into the mixture before baking.
• Other Vegetables – Feel free to swap out the green beans for broccoli or other favorites; it’s a great way to add variety!
• Low-Sodium Cream of Mushroom Soup – To make a healthier version, consider using low-sodium options for that signature flavor without extra salt.
Step‑by‑Step Instructions for Campbells Green Bean Casserole
Step 1: Preheat the Oven or Air Fryer
Begin by preheating your oven or air fryer to 350°F (175°C). This temperature is essential to ensure that your Campbells Green Bean Casserole bakes evenly. If using an oven, take out a 9×9 casserole dish and lightly spray it with non-stick cooking spray to prevent sticking.
Step 2: Prepare the Green Beans
If you opted for fresh green beans, wash, cut, and blanch them in boiling water for 2 minutes. After blanching, quickly drain them and transfer to cold water to stop the cooking process. If using canned green beans, simply drain them and set aside, as they are ready to incorporate into the casserole.
Step 3: Mix the Mushroom Sauce
In a large mixing bowl, combine the cream of mushroom soup with milk, stirring until the mixture is smooth and well-blended. Next, add the soy sauce, enhancing the flavor profile of your dish. This creamy base will envelop the green beans, giving your Campbells Green Bean Casserole its iconic taste.
Step 4: Combine Ingredients
Fold the prepared green beans and 2/3 of the crispy fried onions into the mushroom mixture. Sprinkle in a bit of pepper to season, but refrain from adding salt since the soup and onions contain ample sodium. Mix until everything is nicely combined, creating a delicious filling for your casserole.
Step 5: Assemble the Casserole
Pour the green bean mixture into the prepared casserole dish, spreading it evenly. This ensures every bite of your Campbells Green Bean Casserole is bursting with flavor. Smooth out the top with a spatula to make it nice and even, preparing for that crispy onion topping.
Step 6: Bake or Air Fry
For the oven method, place the casserole in the preheated oven and bake for 25 minutes. After this time, give it a gentle stir, top with the remaining crispy French fried onions, and bake for an additional 5 minutes or until the onions are golden brown. If using an air fryer, cook for 10 minutes, stir halfway, then add the onions and air fry for another 2-3 minutes until crispy.
Step 7: Check and Serve
Once baked or air-fried, check that the center is hot and bubbly before removing it from the oven or air fryer. This visual cue is a great indicator that your Campbells Green Bean Casserole is ready to serve. Allow it to cool slightly before serving, and watch as your guests dive in for seconds!
