This cozy, warming casserole combines chicken and the best flavors of the delicious soup

The recipe for French Onion Chicken Casserole could not be more straightforward. It even uses a shortcut–a store-bought rotisserie chicken to skip the step of roasting your own.

The ingredients include butter, mushrooms, thinly sliced onions, thyme, salt, pepper, flour, wine, beef broth, a hard, crusty loaf of bread gruyère, and parmesan cheese.

You can also substitute Swiss and Muenster cheese if they are easier to find at your local grocer.

Cut up the bread into slices to be used as part of the final dish.

How to make French Onion Chicken Casserole

Ree Drummond shared some of her top comfort foods similar to her French Onion Chicken Cassrole in a video published on YouTube.

First, preheat the oven to 425 ̊degrees.

While it is heating, grease a baking dish deep and wide enough to hold the tasty ingredients.

Melt one tablespoon butter in the pot and add mushrooms until a deep brown color is achieved. Remove from the pot.

Add more butter to the pan and add sliced onions. Saute until they have achieved a soft consistency and a golden brown color. It could take some time. Therefore, keep the heat on low and keep stirring to prevent sticking.

Add the mushrooms back to the pot, followed by the thyme, salt, and pepper to taste.

Next, add the four and keep stirring to coat the vegetables. This mixture will be the base of the sauce and will thicken the final dish.

Once coated, add the wine, followed by the broth and the chicken you have pulled off of the bone.

Cook until the sauce has finished thickening.

First, add one-third of the onion-chicken mixture is to the bottom of the dish. The sliced break comes next, followed by some of the cheeses.

Follow the same method of layering each ingredient until topped with cheese that will brown and bubble while it cooks.

Cover with foil and bake in the oven for around 20 minutes or so. Then, take the foil off and allow the top to brown.

As with any casserole, it should rest for about 10 minutes or so before serving.

Ree Drummond admits this dish is even better the next day

“Don’t worry if you can’t finish this whole casserole in one sitting. It will taste just as good the next day, too!” she admitted.
