Ingredients

2 pounds boneless, skinless chicken breasts (about 4 to 6 pieces)
1 (10.5-ounce) can condensed golden mushroom soup
1 cup sour cream
1 (6-ounce) can crispy fried onions, divided

Step-by-Step Instructions

1. Prepare the Oven and Baking Dish

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of oil to prevent sticking.

2. Prepare the Chicken

Pat the chicken breasts dry using paper towels. Trim any excess fat. If the pieces are thick, slice them horizontally to create thinner cutlets for even cooking and extra tenderness.

3. Arrange in the Dish

Place the chicken breasts in a single layer in the prepared baking dish. Avoid overcrowding so the sauce can coat each piece evenly.

4. Make the Creamy Sauce

In a medium bowl, mix together the golden mushroom soup and sour cream until smooth and fully combined.

5. Add the First Onion Layer

Sprinkle half of the crispy fried onions evenly over the chicken. This creates a delicious savory layer beneath the sauce.

6. Cover with Sauce

Pour the creamy soup mixture over the chicken and onions. Use the back of a spoon to spread it evenly so every piece is fully coated.

7. First Bake

Cover the dish tightly with aluminum foil and bake for 30 minutes.

8. Add Crispy Topping

Remove the foil carefully and sprinkle the remaining fried onions over the top.

9. Finish Baking

Return the dish to the oven uncovered and bake for another 15 to 20 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the onions are crisp and golden brown.

10. Rest and Serve

Let the casserole rest for 5 to 10 minutes before serving. This allows the sauce to thicken slightly and makes serving easier.
