Ingredients
Main Ingredients
1.5 lbs boneless, skinless chicken breasts (about 4 breasts)
1 lb fresh green beans, trimmed
2 tablespoons olive oil
Seasoning
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon kosher salt
½ teaspoon black pepper
Creamy Sauce & Topping
1 can (10.5 oz) condensed cream of mushroom soup
½ cup milk
1 cup shredded cheddar or Parmesan cheese, divided
½ cup French fried onions or seasoned breadcrumbs
Instructions
Prepare the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Season the Chicken
Pat the chicken breasts dry with paper towels. Drizzle with olive oil and season both sides with garlic powder, onion powder, salt, and black pepper.
Arrange the Ingredients
Place the seasoned chicken breasts in the prepared baking dish. Spread the trimmed green beans evenly around the chicken.
Make the Creamy Sauce
In a medium bowl, whisk together the condensed cream of mushroom soup and milk until smooth. Stir in half of the shredded cheese.
Assemble the Casserole
Pour the creamy mixture evenly over the chicken and green beans. Sprinkle the remaining cheese across the top.
Bake
Cover the baking dish loosely with foil and bake for 25 minutes.
Add the Crispy Topping
Remove the foil and sprinkle the French fried onions or seasoned breadcrumbs over the casserole.
Finish Baking
Return the dish to the oven and bake uncovered for an additional 10 to 15 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the topping is golden brown.
Rest and Serve
Allow the casserole to rest for 5 minutes before serving. Spoon extra sauce over each portion and enjoy.
Tips
Choose Even-Sized Chicken Breasts
Uniform pieces cook more evenly and prevent dry spots.
Trim Green Beans Properly
Remove tough ends for the best texture and appearance.
Avoid Overcooking
Use a meat thermometer to ensure perfectly juicy chicken.
Use Freshly Shredded Cheese
Freshly grated cheese melts more smoothly than pre-shredded varieties.
Season Every Layer
A little seasoning throughout the casserole creates deeper flavor.
Blanch Green Beans for Softer Texture
For extra-tender beans, blanch them for 2 to 3 minutes before baking.
Add Extra Vegetables
Mushrooms, carrots, broccoli, or cauliflower work beautifully in this dish.
Let the Dish Rest
Resting allows the sauce to thicken and makes serving easier.
Create More Crunch
Mix breadcrumbs with a tablespoon of melted butter before topping.
Make Ahead
Assemble the casserole several hours in advance and refrigerate until ready to bake.
Variations
Bacon Ranch Version
Add cooked crumbled bacon and a packet of ranch seasoning.
Parmesan Garlic Bake

Cheesy Broccoli Chicken Bake

Spicy Southwest Style
Add diced green chilies, pepper jack cheese, and smoked paprika.
Low-Carb Version
Use heavy cream instead of milk and skip the breadcrumb topping.

Add sautéed mushrooms for extra earthy flavor.
Italian-Inspired Version
Mix in Italian seasoning and mozzarella cheese.
Extra Creamy Version
Add 4 ounces of cream cheese to the sauce mixture.
