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.

I have corrected the instructions to clarify where the cheese gets added in step 6. The cheese is added to the sauce when it is thickening. If you have any other questions, please let me know.
