Ingredients

2 cups cooked white rice
2 cups shredded cooked chicken
1 can (10.5 oz) cream of chicken soup
1 can (10.5 oz) French onion soup
1 cup sour cream
1½ cups shredded mozzarella or Swiss cheese
1½ cups French fried onions, divided
½ teaspoon garlic powder
½ teaspoon onion powder
Salt to taste
Black pepper to taste
Chopped parsley for garnish

Instructions

Step 1: Preheat your oven to 350°F (175°C).
Step 2: In a large bowl, combine the cooked rice, shredded chicken, cream of chicken soup, French onion soup, sour cream, shredded cheese, 1 cup of French fried onions, garlic powder, onion powder, salt, and black pepper. Mix thoroughly until all ingredients are evenly incorporated.
Step 3: Grease a 9×13-inch baking dish and spread the mixture evenly inside.
Step 4: Bake the casserole uncovered for 30 minutes, until it is bubbly around the edges.
Step 5: Remove the casserole from the oven, sprinkle the remaining ½ cup of French fried onions evenly on top, and return it to the oven for an additional 5 minutes until the topping is golden brown and crispy.
Step 6: Once done, remove from the oven, garnish with chopped parsley, and serve hot.

Tips & Variations

Use cooked rotisserie chicken to save time and add extra flavor.
Swap mozzarella or Swiss cheese for Gruyère to enhance the onion flavor.
Add a handful of sautéed mushrooms or spinach for extra veggies.
For a gluten-free version, ensure French fried onions are gluten-free or omit them and add crushed gluten-free crackers as topping.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in a 350°F (175°C) oven for about 15-20 minutes until heated through. The topping may lose some crispness but will still taste delicious.

How to Serve

The dish shows three main layers, served in a white bowl. The bottom layer is creamy white rice mixed with shredded chicken pieces, creating a soft and rich base. The middle layer is melted cheese that stretches as a golden utensil lifts a portion, showing its gooey and stringy texture. The top layer consists of crispy golden-brown fried onion rings scattered evenly, with small green parsley bits sprinkled for color contrast. The bowl sits on a white marbled surface, and the background is a simple dark grey, making the dish stand out clearly. photo taken with an iphone --ar 4:5 --v 7
