Let’s Get Started
Step 1: Preheat the Oven
Set your oven temperature to 350°F (175°C). It’s always best to start with a preheated oven so your casserole gets that nice bubbly edge.
Step 2: Mix the Ingredients
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 until everything is well combined. It should look creamy and inviting. Honestly, at this point, just take a moment to appreciate how good it smells!
Step 3: Prepare the Baking Dish
Grease a 9×13-inch baking dish with cooking spray or a little butter. This is crucial to prevent sticking—trust me, it’s a lesson learned the hard way!
Step 4: Pour the Mixture
Pour the rice and chicken mixture evenly into the greased baking dish. Spread it out a bit so it cooks evenly.
Step 5: Bake the Casserole
Bake uncovered for 30 minutes, or until the edges are bubbly. You’ll know it’s ready when you see those delicious, golden-brown bubbles forming around the edges. It’s like a little piece of heaven!

Sprinkle the remaining ½ cup of French fried onions on top. This is where the magic happens! It adds that final layer of crunch and flavor.
