Eileen's Tips for Success
- Drained canned green beans can be used for this recipe.
- Be sure the green beans are defrosted so they do not get watery as they cook.
- To avoid a runny green bean casserole, make sure the sauce is thickened before adding it to the rest of the ingredients.
- Use leftover chicken from oven baked thighs, oven baked chicken breasts, or shredded chicken made in the instant pot for this easy green bean chicken casserole.

- Use a cup of homemade condensed chicken soup in the sauce.
- Vegetarian: Substitute the chicken with 2 (15-ounce) cans of drained and rinsed white beans.
- Toppings: If you want to make this dish without fried onions, you can top it with crushed Ritz crackers or even cornflakes.
- Gluten-Free: Use a gluten-free flour and gluten-free fried onions.
- Leftover chicken: This is a great way to use up leftover rotisserie chicken if you have some on hand.
