Step‑by‑Step Instructions for French Onion Chicken Rice Bake
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While the oven warms up, grab a large mixing bowl and set it on your counter. This is where all the magic will happen, so make sure you have enough space to comfortably mix your ingredients without any spillover.
Step 2: Combine the Ingredients
In the mixing bowl, combine your cooked white rice, shredded chicken, cream of chicken soup, French onion soup, and sour cream. Sprinkle in garlic powder, onion powder, salt, and black pepper to taste. Use a spatula to mix everything together until thoroughly combined, ensuring each ingredient is evenly distributed for a delicious flavor in your French Onion Chicken Rice Bake.
Step 3: Transfer to Baking Dish
Once your mixture is well combined, take a greased 9×13-inch baking dish and pour the mixture into it. Spread the blend evenly across the dish, smoothing out the top with a spatula. This will ensure that your casserole cooks evenly, giving you that perfect comforting texture throughout.
Step 4: Bake the Casserole
Place your baking dish in the preheated oven and bake uncovered for about 30 minutes. You’ll know it’s ready when the edges begin to bubble and the center is hot. This is where the aroma of the French Onion Chicken Rice Bake fills your kitchen, making it hard to resist!
Step 5: Add Crispy Onions
Once the casserole has baked for 30 minutes, carefully remove it from the oven. Sprinkle the remaining French fried onions evenly over the top of the casserole. This step adds that essential crunch, so get it just right before returning the dish to the oven for an additional 5 minutes.
Step 6: Final Touches and Serve
After another 5 minutes, check that the French fried onions have turned golden and crispy. Once satisfied, remove the casserole from the oven and let it cool for a moment.
