This green bean casserole is creamy, savory, and has the perfect crunch from the onions. It tastes so good could eat the whole pan by myself in one sitting.
Add everything but half of the onions to a mixing bowl and stir well to combine.
Pour mixture into a 7 inch round baking dish (see notes).
Air fry at 350 degrees for 5 minutes. Sprinkle with the remaining half of fried onions and cook for 3 minutes more.
Serve hot.
Notes
Choose a baking dish that will fit inside your air fryer. Small disposable foil pans often work.Cream of chicken soup works well in place of cream of mushroom if you have picky eaters in your family.
