How to Make Chicken Green Bean Casserole

Thicken sauce: Mix in the flour, salt, and white pepper, stirring to coat the vegetables well. Gradually stir in the chicken broth, cooking until the mixture thickens. Add the half and half, reducing heat, and stir until the sauce is thick enough to coat the back of a spoon.
Combine ingredients: In a large bowl, toss the cooked, cubed chicken, thawed green beans, and 1 cup of fried onions. Pour the creamy sauce over the mixture and stir gently until everything is evenly coated.
Transfer to dish: Spread your delicious mixture into the prepared casserole dish, smoothing the top to ensure even cooking.
