Step‑by‑Step Instructions for French Onion Chicken Rice Bake
Step 1: Preheat the Oven
Begin your cozy cooking adventure by preheating your oven to 350°F (175°C). This ensures that your French Onion Chicken Rice Bake bakes evenly, creating that perfect creamy texture inside while achieving a beautiful golden crust on top. As it heats, gather your ingredients for a seamless cooking experience.
Step 2: Mix the Ingredients
In a large mixing bowl, combine the cooked white rice, shredded cooked chicken, cream of chicken soup, French onion soup, sour cream, and shredded cheese. Add 1 cup of French fried onions, garlic powder, onion powder, salt, and black pepper. Stir everything together thoroughly until well blended, ensuring every bite captures the hearty goodness of this casserole.
Step 3: Prepare the Baking Dish
Grease a 9×13-inch baking dish with cooking spray or a light coat of oil to prevent sticking. This step is crucial for a hassle-free serving experience later. Once greased, pour the mixed ingredients evenly into the prepared baking dish, spreading them out to ensure even cooking throughout your French Onion Chicken Rice Bake.
Step 4: Bake the Casserole
Place the baking dish into your preheated oven and bake uncovered for approximately 30 minutes. You’ll know it’s ready when the edges bubble gently, releasing a delicious aroma throughout your kitchen. This step lets the flavors meld beautifully while the casserole heats up thoroughly.
Step 5: Add the Crunch
After 30 minutes, carefully remove the casserole from the oven. Sprinkle the remaining ½ cup of French fried onions on top for that irresistible crunch. This addition will elevate the texture, giving you a delightful contrast to the creamy interior. Return it to the oven for an additional 5 minutes, until the onions turn a lovely golden brown.
Step 6: Garnish and Serve
Once baked, take your French Onion Chicken Rice Bake out of the oven and let it rest for a few moments. Before serving, garnish with chopped parsley to add a splash of color and freshness. Dish it out while warm and watch as your family enjoys this comforting meal!
