Campbells Green Bean Casserole Irresistible Recipe Idea
Ingredients
Method
- If using frozen green beans, make sure they are fully thawed and drained; for fresh beans, trim and slice into 2-inch pieces, then quickly boil in salted water before draining; canned beans just need to be well drained.
- Heat your oven to 350°F, or get your air fryer ready at the same temperature.
- Divide the crispy fried onions into two parts: about 2/3 cup for mixing in the casserole and 1/3 cup to top it off later.
- In a large bowl, whisk together the cream of mushroom soup, milk, and soy sauce until the mixture is smooth and uniform.
- Add the prepared green beans, the 2/3 cup of fried onions, and ground black pepper to the creamy mixture, folding gently to coat the beans evenly without crushing the onions.
- Transfer this green bean mixture to a 9×9 inch baking dish, smoothing the top layer evenly.
- Bake in the preheated oven for 25 minutes or air fry for 10 minutes, until bubbly and heated through.
- Take the casserole out, stir gently to mix the sauce evenly, then sprinkle the reserved 1/3 cup of fried onions on top.
- Return the casserole to the oven and bake for another 5 minutes or air fry for 2 minutes until the onions turn golden brown and crispy, giving a delightful crunchy topping.
Notes
- For best results, use whole milk to keep the casserole creamy. Reserving the fried onions until the end ensures a crisp topping. This dish pairs wonderfully with holiday roasts and can be prepared ahead and baked just before serving.
