Step‑by‑Step Instructions for French Onion Chicken Rice Bake

Step 1: Preheat & Prepare
Preheat your oven to 350°F (175°C) to get things warming up! Meanwhile, gather all your ingredients in a large mixing bowl. This includes your cooked white rice, shredded chicken, cream of chicken soup, French onion soup, sour cream, shredded cheese, and seasonings. Having everything ready will make the cooking process smooth and enjoyable.

Step 2: Combine Ingredients
In the mixing bowl, combine the white rice, shredded chicken, cream of chicken soup, French onion soup, sour cream, and shredded cheese. Add half of the French fried onions, garlic powder, onion powder, salt, and black pepper. Stir gently until everything is well mixed and creamy. This delightful mixture is the base of your French Onion Chicken Rice Bake!

Step 3: Transfer to Baking Dish
Lightly grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking. Carefully transfer the creamy mixture into the dish, spreading it out evenly with a spatula. This helps ensure that every bite of the French Onion Chicken Rice Bake will be perfectly comforting and delicious as it bakes.

Step 4: Bake Casserole
Place the baking dish in the preheated oven and bake uncovered for about 30 minutes. You’ll know it’s ready when the edges are bubbling and the center is hot. This step allows all the flavors to meld beautifully together, creating that irresistible comfort food experience we all love.

Step 5: Add Crispy Topping
After 30 minutes, take the casserole out of the oven. Sprinkle the remaining French fried onions evenly on top of the bake. Return the dish to the oven and bake for another 5 minutes until the topping is golden brown and crispy. Watching those onions crisp up is so satisfying and will enhance the flavor of your French Onion Chicken Rice Bake!

Step 6: Garnish & Serve
Once baked, let the casserole cool for a few minutes before serving. This allows for easier cutting and serving. Finally, garnish with freshly chopped parsley to add a pop of color.
