Tools You’ll Need
Large skillet
9×13 inch baking dish
Mixing bowl
Whisk or spoon
Aluminum foil

Step-by-Step Instructions

Step 1: Prep and Sear the Chicken

1. Preheat oven to 350°F (175°C).
2. In a shallow bowl, mix flour, salt, and black pepper.
3. Dredge each chicken cutlet in the flour mixture, coating both sides.
4. In a large skillet, heat olive oil and butter over medium-high heat.
5. Sear chicken cutlets for 2-3 minutes per side until lightly golden (they don’t need to be fully cooked).
6. Transfer seared chicken to a greased 9×13-inch baking dish.

Step 2: Make the Creamy Mushroom Sauce

1. In the same skillet, melt 1 tbsp butter.
2. Add onions and cook for 2-3 minutes until translucent.
3. Add garlic and mushrooms and cook for another 5 minutes, until mushrooms are browned and tender.
4. Stir in cream of mushroom soup, chicken broth, milk, pepper, and thyme.
5. Simmer for 3-4 minutes, stirring until everything is well combined and slightly thickened.

Step 3: Assemble the Casserole

1. Pour the mushroom sauce evenly over the chicken in the baking dish.
2. Lay cheese slices on top of the chicken and sauce.
3. Cover the dish with foil.

Step 4: Bake the Casserole

1. Bake for 25 minutes covered.
2. Remove the foil and bake an additional 10-15 minutes, until the cheese is bubbly and slightly golden.
3. Let the casserole rest for 5 minutes before serving.

Step 5: Garnish and Serve

1. Sprinkle with fresh parsley for color and freshness.
2. Serve with rice, mashed potatoes, egg noodles, or crusty bread to soak up the sauce.

Tips for Success
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.

Serving Suggestions
Buttered Egg Noodles – A classic pairing with creamy chicken.
Steamed Green Beans – Light and fresh to balance the richness.
Garlic Bread – Great for soaking up that delicious sauce.
Simple Side Salad – A crisp, refreshing complement to the creamy casserole.

Frequently Asked Questions

1. Can I use chicken thighs instead of breasts?
   Yes! Boneless, skinless thighs work great and stay juicy in the oven.
2. What can I use instead of cream of mushroom soup?
   You can use cream of chicken soup or make your own homemade white sauce with butter, flour, and milk.
3. Can I make it dairy-free?
   Use dairy-free cheese and substitute the milk with a plant-based milk. Make sure your soup base is also dairy-free.
4. Is it okay to skip the cheese?
   Yes, but the cheese adds richness and a gooey texture. You can use less or choose a dairy-free option if preferred.
5. Can I double the recipe?
   Absolutely! Just use a larger casserole dish and adjust baking time slightly.
