You’ll be amazed at how quickly this one-pan French onion chicken casserole comes together, perfect for when you’re craving something hearty and flavorful without the fuss. Follow these simple steps, and soon you’ll be enjoying a truly comforting meal.

1. Step 1: First things first, let’s get that oven preheating! Set it to 350ºF (175ºC). While it heats up, lightly spray a 9×9-inch baking dish with your favorite cooking spray. This little step prevents sticking and makes cleanup a breeze.
2. Step 2: In a large bowl, combine the 4 cups of cooked chopped chicken. I love using rotisserie chicken for this because it’s already tender and flavorful, saving me so much time.
3. Step 3: Add the 1 cup shredded cheddar cheese, the 1 cup refrigerated sour cream French Onion Dip, and the 1 (10.5-oz) can unsalted cream of chicken soup to the bowl with the chicken.
4. Step 4: Now, it’s time to mix it all up! Gently but thoroughly combine all the ingredients with a spoon or spatula until everything is well incorporated. You want that creamy dip and soup to coat every piece of chicken and cheese. The mixture should look luscious and ready for baking. This is where the magic starts for how to make French onion chicken casserole truly special.
5. Step 5: Carefully spread the chicken mixture evenly into your prepared baking dish. Use your spoon to smooth the top, creating a nice, even layer for the topping.
6. Step 6: Sprinkle the entire top of the casserole evenly with the 1 (2.8-oz) can of French fried onions. Make sure you get them all the way to the edges for that perfect, crispy crunch in every bite.
7. Step 7: Place the dish in the preheated oven and bake uncovered for 30 to 40 minutes. You’re looking for the casserole to be hot and bubbly around the edges, and for those glorious French fried onions to turn a beautiful golden brown. The aroma filling your kitchen at this stage is just incredible!

How to Store and Reheat French Onion Chicken Casserole

Leftovers of this delicious French onion chicken casserole are a treat, and storing them properly ensures they stay just as tasty. Once your casserole has cooled down a bit, typically for about 30 minutes after coming out of the oven, you can safely store it.

When you’re ready to enjoy your leftovers, reheating is simple. For refrigerated portions, you can gently warm them in the microwave for a minute or two until heated through, or pop them back into a 350ºF (175ºC) oven for about 15-20 minutes until bubbly. For frozen portions, thaw them overnight in the refrigerator first, then reheat as you would the refrigerated leftovers. Just be aware that the crispy onion topping might not be quite as crunchy after reheating, but the flavor will still be fantastic!
