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

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This prepare the environment for your French Onion Chicken Rice Casserole, ensuring that it’s hot and ready to bake as soon as you assemble the dish. This step is crucial for achieving that dreamy, bubbling finish!

Step 2: Caramelize the Onions
In a large skillet, heat a tablespoon of olive oil over medium heat. Add the thinly sliced onions and sauté them gently, stirring occasionally for about 10 minutes, or until they become a rich, golden brown. The caramelization process enhances the sweetness of the onions, which is essential for the flavor profile of the casserole.

Step 3: Combine Ingredients
In a large mixing bowl, combine the diced boneless, skinless chicken breasts, uncooked long-grain white rice, chicken broth, French onion soup, sour cream, garlic powder, onion powder, salt, and pepper. Stir the mixture thoroughly so that all ingredients are evenly distributed, ensuring every bite of your French Onion Chicken Rice Casserole is packed with flavor.

Step 4: Incorporate Caramelized Onions
Once the onions are caramelized, gently fold them into the chicken and rice mixture from the previous step. This not only adds a delicious depth of flavor but also contributes to the overall texture of the casserole. Make sure every component is coated well before moving to the next step.

Step 5: Transfer to Casserole Dish
Grease a 9×13 inch casserole dish with a little olive oil or cooking spray. Pour the combined mixture into the prepared dish, spreading it out evenly. This ensures that the heat will distribute properly during baking, helping your French Onion Chicken Rice Casserole cook thoroughly.

Step 6: Cover and Bake
Cover the casserole dish loosely with aluminum foil, which helps retain moisture as it bakes. Place the dish in the preheated oven and bake for 30 minutes. This initial covered baking allows the flavors to meld beautifully while ensuring the rice cooks properly.

Step 7: Add Cheese Topping
After 30 minutes, carefully remove the foil and take a moment to admire your casserole. Sprinkle shredded mozzarella cheese generously over the top, giving it that deliciously gooey, cheesy finish. Return the dish to the oven, uncovered, and bake for an additional 15 minutes, or until the cheese is bubbling and golden brown.

Step 8: Cool and Serve
Once baked, take the French Onion Chicken Rice Casserole out of the oven and allow it to cool for a few minutes. This resting period helps the casserole set, making it easier to serve. Garnish with freshly chopped parsley for a pop of color before diving into this heartwarming family dish!
