Step-by-Step Instructions

Step 1: Prepare and Sear the Chicken

1. Preheat your oven to 350°F (175°C).
2. In a shallow bowl, mix the flour, salt, and pepper.
3. Lightly coat each chicken cutlet in the flour mixture.
4. In a large skillet, heat the olive oil and butter over medium-high heat.
5. Sear the chicken cutlets for 2-3 minutes on each side until lightly golden. They don’t need to be cooked through.
6. Place the browned chicken cutlets in a greased 9×13-inch baking dish.

Step 2: Make the Mushroom Sauce

1. In the same skillet, melt 1 tbsp butter over medium heat.
2. Add chopped onions and sauté for 2-3 minutes until translucent.
3. Stir in the garlic and sliced mushrooms. Cook for 5-6 minutes, stirring occasionally, until the mushrooms are tender and browned.
4. Add the cream of mushroom soup, chicken broth, and milk. Stir until well combined.
5. Season with thyme, salt, and black pepper. Simmer for 3-4 minutes until slightly thickened.
6. Pour the sauce evenly over the chicken in the baking dish.

Step 3: Add Cheese and Bake

1. Layer one slice of cheese over each piece of chicken.
2. Cover the baking dish with foil.
3. Bake for 25 minutes, then remove the foil and bake for another 10-15 minutes until the cheese is bubbly and slightly golden on the edges.
4. Let the casserole rest for 5 minutes before serving.

Step 4: Garnish and Serve

1. Sprinkle with fresh parsley for a pop of color and freshness.
2. Serve warm with your favorite side dish.
