## Ingredients You’ll Need

Here’s a breakdown of the ingredients you’ll need to create this culinary masterpiece:

* **Chicken:** 2 pounds boneless, skinless chicken breasts, cut into 1-inch pieces. Chicken thighs can also be used for a richer flavor.
* **Mushrooms:** 1 pound cremini mushrooms, sliced. You can also use button mushrooms, shiitake mushrooms, or a combination of different types.
* **Onion:** 1 medium yellow onion, chopped. This adds a foundational savory flavor to the dish.
* **Garlic:** 2 cloves garlic, minced. Garlic enhances the overall flavor profile and adds a pungent aroma.
* **Butter:** 4 tablespoons unsalted butter. Butter provides richness and helps sauté the vegetables and chicken.
* **All-Purpose Flour:** 4 tablespoons all-purpose flour. Flour is used to thicken the creamy sauce.
* **Chicken Broth:** 2 cups chicken broth. Chicken broth forms the base of the sauce and adds depth of flavor.
* **Heavy Cream:** 1 cup heavy cream. Heavy cream adds richness and creates a luxurious texture.
* **Dry Sherry (Optional):** 1/4 cup dry sherry. Sherry adds a subtle nutty flavor to the sauce. If you don’t have sherry, you can omit it or substitute it with white wine.
* **Fresh Thyme:** 1 tablespoon fresh thyme leaves, chopped. Thyme adds a fresh, earthy aroma and flavor.
* **Salt and Pepper:** To taste. Seasoning is crucial for bringing out the flavors of the ingredients.
* **Shredded Cheese:** 1 1/2 cups shredded Gruyere, Swiss, or Parmesan cheese. Cheese adds a delicious, melty topping to the casserole. A combination of cheeses works well too!
* **Breadcrumbs (Optional):** 1/2 cup panko breadcrumbs. Breadcrumbs add a crispy topping to the casserole. Toss them with melted butter for extra flavor.
* **Olive Oil:** 1 tablespoon. Used for initial sautéing.

## Step-by-Step Instructions

Follow these simple steps to create your own creamy chicken and mushroom casserole:

**1. Prepare the Chicken and Mushrooms:**

* Cut the chicken breasts into 1-inch pieces. Pat them dry with paper towels to ensure they brown properly. Season with salt and pepper.
* Slice the mushrooms into 1/4-inch thick slices.
* Chop the onion and mince the garlic.
* Chop the fresh thyme.

**2. Sauté the Chicken and Vegetables:**

* Heat 1 tablespoon of olive oil in a large skillet or Dutch oven over medium-high heat.
* Add the chicken and cook until browned on all sides. It doesn’t need to be cooked through completely at this stage.
* Remove the chicken from the skillet and set aside.
* Add the butter to the skillet and let it melt. Add the chopped onion and cook until softened, about 5 minutes.
* Add the minced garlic and cook for another minute until fragrant.
* Add the sliced mushrooms and cook until they release their moisture and become tender, about 8-10 minutes.

**3. Make the Creamy Sauce:**

* Sprinkle the flour over the mushrooms and cook for 1 minute, stirring constantly to avoid lumps.
* Gradually whisk in the chicken broth, scraping up any browned bits from the bottom of the skillet.
* Bring the mixture to a simmer and cook until the sauce thickens, about 5 minutes.
* Stir in the heavy cream, dry sherry (if using), and fresh thyme. Season with salt and pepper to taste.

**4. Assemble the Casserole:**

* Preheat your oven to 375°F (190°C).
* Add the browned chicken back to the skillet with the creamy mushroom sauce.
* Stir to combine and ensure the chicken is evenly coated.
* Pour the mixture into a greased 9×13 inch baking dish.
* Sprinkle the shredded cheese evenly over the top of the casserole.
* If using breadcrumbs, toss them with melted butter and sprinkle them over the cheese.

**5. Bake the Casserole:**

* Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the top is golden brown.
* Let the casserole rest for 10 minutes before serving.

## Tips and Variations

* **Add Vegetables:** Feel free to add other vegetables to the casserole, such as peas, carrots, or broccoli. Sauté them along with the mushrooms.
* **Use Different Cheeses:** Experiment with different types of cheese, such as cheddar, Monterey Jack, or provolone. A combination of cheeses can add complexity to the flavor.
* **Add Bacon:** Cooked and crumbled bacon adds a smoky and savory flavor to the casserole.
* **Use Different Herbs:** Try using different herbs, such as rosemary, sage, or parsley, instead of thyme.
* **Make it Gluten-Free:** Use gluten-free flour to thicken the sauce and gluten-free breadcrumbs for the topping.
* **Spice it Up:** Add a pinch of red pepper flakes to the sauce for a little heat.
* **Use a Rotisserie Chicken:** For an even quicker meal, use shredded rotisserie chicken instead of cooking chicken breasts. Just add it to the sauce at the end.

## Serving Suggestions

This creamy chicken and mushroom casserole is delicious on its own, but it also pairs well with a variety of side dishes:

* **Mashed Potatoes:** A classic pairing that complements the creamy sauce perfectly.
* **Rice:** Serve the casserole over rice for a hearty and satisfying meal.

* **Steamed Vegetables:** Steamed green beans, broccoli, or asparagus are healthy and delicious side dishes.
