Ingredients
For the Chicken:
-
3 boneless, skinless chicken breasts (sliced lengthwise to make 6 thin cutlets)
-
½ cup all-purpose flour
-
½ tsp salt
-
½ tsp black pepper
-
1 tbsp olive oil
-
1 tbsp butter
For the Sauce:
-
1 tbsp butter
-
1 small onion, finely chopped
-
2 cloves garlic, minced
-
1 cup fresh mushrooms, sliced (button or cremini work great)
-
1 can (10.5 oz) cream of mushroom soup
-
½ cup chicken broth
-
½ cup milk
-
¼ tsp black pepper
-
¼ tsp dried thyme
Topping:
-
6 slices of mild cheese (like Muenster, mozzarella, or Swiss)
-
2 tbsp fresh parsley, chopped (optional, for garnish)
Instructions
Step 1: Prep and Sear the Chicken
-
Preheat oven to 350°F (175°C).
-
In a shallow bowl, mix flour, salt, and black pepper.
-
Dredge each chicken cutlet in the flour mixture, coating both sides.
-
In a large skillet, heat olive oil and butter over medium-high heat.
-
Sear chicken cutlets for 2-3 minutes per side until lightly golden (they don’t need to be fully cooked).
-
Transfer seared chicken to a greased 9×13-inch baking dish.
Step 2: Make the Creamy Mushroom Sauce
-
In the same skillet, melt 1 tbsp butter.
-
Add onions and cook for 2-3 minutes until translucent.
-
Add garlic and mushrooms and cook for another 5 minutes, until mushrooms are browned and tender.
-
Stir in cream of mushroom soup, chicken broth, milk, pepper, and thyme.
-
Simmer for 3-4 minutes, stirring until everything is well combined and slightly thickened.
Step 3: Assemble the Casserole
-
Pour the mushroom sauce evenly over the chicken in the baking dish.
-
Lay cheese slices on top of the chicken and sauce.
-
Cover the dish with foil.
Step 4: Bake the Casserole
-
Bake for 25 minutes covered.
-
Remove the foil and bake an additional 10-15 minutes, until the cheese is bubbly and slightly golden.
-
Let the casserole rest for 5 minutes before serving.
Step 5: Garnish and Serve
-
Sprinkle with fresh parsley for color and freshness.
-
Serve with rice, mashed potatoes, egg noodles, or crusty bread to soak up the sauce.
Notes
Thin Chicken is Key – Slice chicken breasts lengthwise for even cooking and perfect tenderness.
Don’t Overcook – Chicken finishes cooking in the oven, so just a quick sear is enough.
Cheese Options – Use your favorite mild melting cheese. Muenster, mozzarella, or Swiss all work wonderfully.
Make It Ahead – Assemble the casserole a day in advance, cover, refrigerate, and bake when needed.
Add Veggies – For extra nutrition, add a layer of spinach or steamed broccoli before baking.
