Ingredients

• 2 pieces boneless, skinless chicken breasts
• 2 tablespoons olive oil
• 2 tablespoons butter
• 8 ounces mushrooms, sliced
• 2 cloves garlic, minced
• 2 tablespoons all-purpose flour
• 1.5 cups chicken broth
• 0.5 cups heavy cream
• 1 teaspoon dried thyme
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 cup shredded cheddar cheese
• 1 cup bread crumbs
• 1 tablespoon parsley, chopped (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Season the chicken breasts on both sides with a pinch of salt and pepper.

Step 3

Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Sear the chicken breasts for 3-4 minutes on each side until golden brown (they don't need to be fully cooked). Remove chicken from the skillet and set aside.

Step 4

In the same skillet, add the remaining tablespoon of olive oil and butter. Once melted, sauté the sliced mushrooms over medium heat until they release their liquid and brown slightly, about 5 minutes.

Step 5

Add the minced garlic to the mushrooms and cook for another minute until fragrant.

Step 6

Sprinkle the flour over the mushroom mixture and stir well to coat. Cook for 1-2 minutes to remove the raw flour taste.

Step 7

Gradually pour in the chicken broth while stirring to avoid lumps, followed by the heavy cream. Mix well until the sauce is smooth.

Step 8

Stir in the dried thyme, 1 teaspoon of salt, and 0.5 teaspoon of black pepper. Let the sauce simmer for 2-3 minutes until it thickens slightly.

Step 9

Place the seared chicken breasts into a greased casserole dish. Pour the mushroom sauce over the chicken, spreading it evenly.

Step 10

Sprinkle the shredded cheddar cheese over the sauce, followed by the bread crumbs for a crispy topping.

Step 11

Bake in the preheated oven for 20-25 minutes until the chicken is fully cooked and the topping is golden brown.

Step 12

Garnish with chopped parsley, if desired, and serve warm.
