Ingredients
For the Chicken and Green Beans
- 1 1/2 pounds boneless, skinless chicken breasts or thighs
- 4 cups fresh green beans, trimmed
- 1 tablespoon olive oil
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon paprika
- 1/2 teaspoon Italian seasoning
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For the Creamy Sauce
- 1 can (10.5 ounces) cream of chicken soup
- 1/2 cup sour cream
- 1/2 cup chicken broth
- 2 cloves garlic, minced
- 1/2 teaspoon onion powder
- 1/4 teaspoon black pepper
- 1/2 cup shredded Parmesan cheese
For the Topping
- 1 cup shredded mozzarella cheese
- 1/2 cup shredded cheddar cheese
- 1/2 cup crispy fried onions, optional
- 1 tablespoon chopped fresh parsley, optional
Instructions
1. Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9 x 13-inch baking dish with cooking spray or a little olive oil.
2. Prepare the Green Beans
Bring a large pot of water to a boil.
Add the trimmed green beans and blanch for about 3–4 minutes, until they become bright green and slightly tender.
Drain and immediately rinse with cold water to stop the cooking process.
Set aside.
3. Season the Chicken
Pat the chicken dry with paper towels.
If using chicken breasts, cut them into bite-sized pieces so they cook more evenly.
Place the chicken in a bowl and toss with olive oil, garlic powder, onion powder, paprika, Italian seasoning, salt, and black pepper.
4. Make the Creamy Sauce
In a large bowl, combine the cream of chicken soup, sour cream, chicken broth, minced garlic, onion powder, black pepper, and Parmesan cheese.
Stir until smooth and well combined.
The sauce should be creamy but pourable. If it seems too thick, add another tablespoon or two of chicken broth.
5. Assemble the Casserole
Spread the blanched green beans evenly across the bottom of the prepared baking dish.
Add the seasoned chicken pieces.
Pour the creamy sauce evenly over the chicken and green beans.
Gently toss or spread the mixture so everything is coated.
6. Add the Cheese
Sprinkle the mozzarella and cheddar evenly over the top.
If you’re using crispy fried onions, reserve them for the final part of baking so they stay crunchy.
7. Bake
Cover the dish loosely with aluminum foil and bake for approximately 25 minutes.
Remove the foil and continue baking for another 10–15 minutes, or until the chicken is completely cooked and the cheese is melted and lightly golden.
The chicken should reach an internal temperature of 165°F (74°C) in the thickest pieces.
If using crispy fried onions, sprinkle them over the casserole during the final 5 minutes of baking.
8. Rest and Serve
Remove the casserole from the oven and let it rest for about 5–10 minutes.
Garnish with fresh parsley if desired and serve warm.
Tips for the Best Chicken and Green Bean Bake
Cut the chicken evenly: Similar-sized pieces cook at roughly the same rate and make the casserole easier to serve.
Don’t skip blanching the green beans: This helps them become tender while still maintaining some texture and color.
Don’t overbake: Once the chicken reaches 165°F, remove the casserole from the oven to help keep the chicken juicy.
Use freshly shredded cheese: It generally melts more smoothly and gives the casserole a better texture.
Add the crunchy topping at the end: Fried onions can become soft if they’re covered with sauce for the entire baking time.
Easy Variations
Use Rotisserie Chicken
For a quicker version, replace the raw chicken with about 3 cups of shredded cooked chicken. Since the chicken is already cooked, reduce the baking time and bake until the casserole is hot and the cheese is melted.
Add Mushrooms
Sauté sliced mushrooms with a little butter or olive oil and add them to the casserole for extra savory flavor.
Make It Spicy
Add crushed red pepper flakes, cayenne pepper, or diced jalapeños to the sauce.
Try Different Cheese
Use Monterey Jack, Colby, Gruyère, or a combination of your favorite melting cheeses.
Add Bacon
Crispy cooked bacon makes a delicious addition and adds a smoky, savory flavor.
What to Serve With It
This casserole is filling enough to serve as a complete meal, but it pairs nicely with:
- Mashed potatoes
- Rice
- Garlic bread
- Dinner rolls
- Roasted potatoes
- Simple green salad
- Steamed vegetables
For a lighter meal, serve it with a fresh salad and skip the additional starch.
Storage and Reheating
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 3–4 days.
Reheat individual portions in the microwave until thoroughly hot, or cover the casserole with foil and warm it in a 350°F (175°C) oven.
If the sauce becomes too thick after refrigeration, add a small splash of chicken broth before reheating.
Final Thoughts
This Ruth’s Chris Chicken and Green Bean Bake is a warm, creamy, and satisfying casserole that turns simple ingredients into a restaurant-inspired comfort meal. Tender seasoned chicken, flavorful green beans, creamy sauce, and melted cheese come together beautifully in every bite.
It’s easy enough for a weeknight dinner but hearty and inviting enough to serve when family and friends gather around the table.
