Step-by-Step Preparation of French Onion Chicken Casserole

Cooking can sometimes feel daunting, but this French Onion Chicken Casserole is designed for ease and enjoyment! Let's break down the preparation process into simple steps.

Prepare the baking dish

First things first, get your oven preheating to 350°F (175°C). This ensures that your casserole will bake evenly from the moment it goes in. While the oven warms up, take an 11-x 7-inch or a 2 ½-quart baking dish and coat it generously with cooking spray. This little step will help your casserole come out easily and cleanly after baking, avoiding the dreaded sticking!

Cook the onion mixture

Now, let’s dive into the heart of this dish: the onions! Heat 3 tablespoons of olive oil in a large skillet over medium heat. Add your thinly sliced onions—don’t rush this process. You want them to cook down slowly. Cover the skillet and stir occasionally, allowing the onions to become tender and start transforming into that beautiful golden color, which should take about 10 to 12 minutes.

Once they’re soft, add kosher salt and black pepper for seasoning (feel free to adjust the amounts to your taste!). Uncover the skillet, and stir in 2 tablespoons of unsalted butter and 2 minced garlic cloves, cooking until fragrant, usually around 1 minute. Sprinkle in ¼ cup of all-purpose flour to thicken the mixture, stirring well. Gradually add 1 cup of chicken broth and bring to a simmer, scraping the bottom of the skillet to release all those delicious, browned bits. Finally, fold in 1 cup of thawed frozen peas and let this mixture cool for about 5 minutes.

Make the chicken mixture

While the onion mixture cools, it’s time to prepare the chicken component. In a large bowl, combine 3 cups of chopped cooked chicken, 1 cup of sour cream, ½ cup of mayonnaise, and 2 tablespoons of chopped fresh parsley. This combination adds a rich creaminess that balances the savory flavors—trust me, it’s worth it!

Combine onion mixture and chicken mixture

Now comes the fun part! Pour the cooled onion mixture into the bowl with the chicken mixture, and gently stir everything together until you have a uniform consistency. Transfer this delicious combo into your prepared baking dish. Top it off with 1 cup of crispy fried onions and a blend of 4 ounces of shredded mozzarella and 2 ounces of Gruyère cheese. Talk about a flavor explosion!

Bake the casserole to perfection

Here’s the final touch: slide the casserole into your preheated oven and bake for 25 to 30 minutes. You’ll know it’s done when the cheese is all melted and bubbly, with gloriously golden brown edges. Once out of the oven, let it cool for about 5 minutes before diving in. Enjoy your French Onion Chicken Casserole hot, and watch everyone come back for seconds!
