Why You’ll Love This Amish Chicken and Green Bean Bake
This casserole uses simple, familiar ingredients and turns them into a filling one-dish dinner.
The chicken stays tender because it is mixed into a creamy sauce rather than baked dry on its own.

How to Make Amish Chicken and Green Bean Bake
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9 x 13-inch baking dish with butter or cooking spray.
Set it aside while you prepare the casserole.
2. Prepare the Green Beans
If using fresh green beans, trim the ends and cut them into approximately 1½-inch pieces.
Bring a pot of lightly salted water to a boil.
Add the beans and cook for approximately 4–5 minutes.
Drain immediately.
The beans should be partially tender but still slightly firm because they will continue cooking in the oven.
If using frozen green beans, thaw and drain them well.
3. Prepare the Chicken
Shred or dice the cooked chicken into bite-sized pieces.
Rotisserie chicken, leftover roasted chicken, baked chicken breast, or poached chicken all work well.
Make sure the chicken is already fully cooked before assembling the casserole.
4. Cook the Onion
Melt 1 tablespoon butter in a large skillet over medium heat.
Add the diced onion.
Cook for approximately 4–5 minutes, stirring occasionally, until softened.
5. Add the Garlic
Add the minced garlic.
Cook for approximately 30–60 seconds, just until fragrant.
Transfer the onion and garlic mixture to a large mixing bowl.
6. Start the Cream Sauce
In the same skillet or a saucepan, melt 3 tablespoons butter over medium heat.
Sprinkle in the flour.
Whisk continuously for approximately 1–2 minutes.
The mixture should become smooth and lightly bubbly.
7. Add the Chicken Broth
Slowly pour in the chicken broth while whisking constantly.
Continue whisking until smooth and lump-free.
8. Add the Milk
Pour in the milk.
Add Dijon mustard, garlic powder, onion powder, thyme, parsley, salt, and black pepper.
Cook over medium-low heat for approximately 4–5 minutes, stirring frequently.
The sauce should thicken enough to coat the back of a spoon.
9. Add the Sour Cream
Reduce the heat to low.
Stir in the sour cream until smooth.
Avoid boiling aggressively once the sour cream is added.
10. Add the Cheese
Stir in the cheddar, mozzarella, and Parmesan.
Add the cheese gradually and stir until melted.
If the sauce becomes too thick, add a small splash of milk or chicken broth.
11. Combine the Filling
Add the cooked chicken, green beans, onions, and garlic to a large mixing bowl.
Pour the creamy cheese sauce over everything.
Gently stir until evenly coated.
12. Transfer to the Baking Dish
Spoon the mixture into the prepared baking dish.
Spread it into an even layer.
Press gently, but do not pack the casserole tightly.
13. Make the Buttery Cracker Topping
In a small bowl, combine the crushed crackers, melted butter, Parmesan, and dried parsley.
Mix until the crumbs are evenly coated.
14. Add the Topping
Sprinkle the cracker mixture evenly over the casserole.
Try to cover most of the surface without pressing the crumbs down.
15. Bake the Casserole
Place the baking dish in the preheated oven.
Bake uncovered for approximately 25–30 minutes.
The filling should be bubbling around the edges and the topping should be golden.
16. Brown the Top if Needed
If you want the topping darker and crispier, switch the oven to broil.
Broil for approximately 1–2 minutes.
Watch continuously so the crumbs do not burn.
17. Rest Before Serving
Remove the casserole from the oven.
Allow it to rest for approximately 5–10 minutes.
This helps the creamy filling settle and makes serving easier.
18. Garnish and Serve
Sprinkle with fresh parsley, extra Parmesan, or cracked black pepper.
Serve warm.
What to Serve With Amish Chicken and Green Bean Bake
This casserole is filling enough to serve as a complete dinner, but it pairs beautifully with simple side dishes.
Serve it with creamy mashed potatoes, roasted baby potatoes, buttered noodles, or steamed rice.
Warm dinner rolls, biscuits, or crusty bread are excellent for soaking up the creamy sauce.
For something fresh, add a garden salad, cucumber salad, tomato salad, or coleslaw.
Roasted carrots or corn also work well if you want extra vegetables.
Tips for the Best Amish Chicken and Green Bean Bake
Use cooked chicken to keep the baking time short.
Do not overcook the green beans before baking.
Drain frozen vegetables thoroughly.
Use freshly shredded cheese for smoother melting.
Keep the cream sauce slightly loose before baking.
Do not boil the sauce aggressively after adding sour cream and cheese.
Use low-sodium chicken broth so you can control the salt level.
Add the cracker topping immediately before baking for the crispiest texture.
Let the casserole rest before serving.

How to Store Leftovers
Allow the casserole to cool before transferring leftovers to an airtight container.
Refrigerate for up to 3–4 days.
To reheat, place individual portions in the microwave until hot throughout.
For larger portions, cover loosely with foil and reheat in a 350°F (175°C) oven until warmed through.
If the casserole seems dry after refrigeration, add a small splash of milk or chicken broth before reheating.
You can also freeze the casserole for approximately 2–3 months.
For best results, freeze it without the cracker topping and add fresh crumbs before baking or reheating.
Thaw overnight in the refrigerator.
Frequently Asked Questions
Can I use rotisserie chicken?
Yes.
Rotisserie chicken is one of the easiest options for this casserole.
Remove the skin and bones, then shred or chop the meat.
Can I use canned green beans?
Yes.
Drain them very well and skip the blanching step.
Because canned green beans are already soft, fold them into the filling gently.
Can I use frozen green beans?
Absolutely.
Thaw them first and drain away excess moisture before adding them to the casserole.
Can I make this ahead?
Yes.
Assemble the filling and refrigerate it for up to about 24 hours.
Add the cracker topping just before baking.
Why is my casserole watery?
The green beans may have contained too much moisture, or the sauce may not have thickened enough before baking.
Drain the beans well and let the sauce simmer until it lightly coats a spoon.
Can I use cream of chicken soup?
Yes.
For a shortcut version, replace the homemade cream sauce with condensed cream of chicken soup thinned with a little milk or broth.
What crackers work best?
Buttery round crackers work especially well.
You can also use panko breadcrumbs, crushed cornflakes, or seasoned breadcrumbs.
Can I add potatoes?
Yes.
Use cooked diced potatoes so they are fully tender by the time the casserole finishes baking.
