How to Make Onion Chicken Casserole
Preparing Your Ingredients
Before anything else, let’s gather all our ingredients. Having everything ready makes cooking smoother and more enjoyable. Start by measuring out your cooked rice and shredded chicken. Check that your soups are ready to go. If you’re using rotisserie chicken, shred it into bite-sized pieces. Chop your parsley for garnish, and let’s get cooking!
Mixing the Casserole Filling
In a large bowl, combine the cooked rice, shredded chicken, cream of chicken soup, and French onion soup. Then, add the sour cream and shredded cheese, stirring gently until all ingredients are evenly coated. Don’t forget to sprinkle in the garlic powder and onion powder. Season with salt and black pepper to taste, creating a vibrant mix that smells heavenly.
Assembling the Casserole
Now it’s time to transfer the mixture into your greased 9×13-inch baking dish. Spread the filling evenly across the dish using a spatula. Make sure every nook and cranny is filled with that delicious mixture. This will help the casserole bake evenly and ensures every bite is packed with flavor!
Baking the Casserole
Preheat your oven to 350°F (175°C) and pop that baking dish in the oven. Bake uncovered for 30 minutes. You’re looking for that bubbling edge; it’s a lovely sight! The smell wafting through your kitchen is sure to draw in everyone’s curiosity during this time.
Finishing Touches
Once the casserole is bubbly, remove it from the oven and sprinkle the remaining French fried onions on top. Return it to the oven and bake for an additional 5 minutes until the onions are golden brown and crispy. Just before serving, add a sprinkle of chopped parsley for a fresh touch. Your Onion Chicken Casserole is now ready to delight!
