– 1 tablespoon finely chopped fresh garlic
Herbs and Seasonings:

– 1 teaspoon kosher salt

Liquids and Condiments:
– 1 (10.5 ounce) can condensed French onion soup
– 1/4 cup dry white wine
– 1 cup sour cream
– 1 cup mayonnaise
– 1 teaspoon Dijon mustard
Cheese:
– 2 cups Gruyère cheese, shredded and divided
Chicken:
– 6 cups chopped rotisserie chicken (approximately 1 1/2 whole rotisserie chickens)
Croutons:

Preparation

First, ensure you have all your ingredients on hand and preheat your oven to 350 degrees F (175 degrees C).

Cooking the Base

In a large skillet over medium heat, melt the butter. Add the chopped onion, celery, carrot, and garlic, along with thyme, salt, and pepper. Cook, stirring frequently, until the onions are softened and translucent, which should take about 5 to 7 minutes.

Simmering Mixture

To your softened vegetable mix, add the French onion soup and white wine. Let it come to a simmer over medium heat, allowing it to thicken slightly for about 2 to 3 minutes. Then, mix in the sour cream, mayonnaise, and Dijon mustard, bringing the mixture back to a simmer. Stir in 1 cup of the Gruyère cheese until it melts completely into the sauce, which should take about a minute. Remove the skillet from heat, and fold in the chopped rotisserie chicken.

Assembling

Transfer the chicken mixture into a 9×13-inch baking dish. Sprinkle the seasoned croutons evenly over the top, followed by the remaining Gruyère cheese.

Baking

Place the dish into the preheated oven and bake until it’s bubbling and the cheese has melted, approximately 12 to 15 minutes. Allow the dish to rest for 10 minutes before serving.

Garnishing and Serving

Finally, garnish with additional thyme leaves and a sprinkle of freshly ground black pepper before serving.

In conclusion, this savory chicken casserole is a delightful way to bring the family around the table. Enjoy a flavorful medley of textures and tastes that are bound to become a household favorite.
