Ingredients

Scale

4 boneless, skinless chicken breasts

1/2 cup all-purpose flour (for dredging)

1/2 tsp salt

1/4 tsp black pepper

2 tbsp olive oil

2 tbsp butter

1 (10.5 oz) can cream of mushroom soup

1/2 cup chicken broth

1/2 cup sour cream

1 tsp garlic powder

1/2 tsp onion powder

1 cup sliced mushrooms

6 slices of deli-style Swiss or mozzarella cheese

Chopped parsley, for garnish (optional)

Instructions

1. Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

2. Pound chicken breasts to even thickness if needed. Season flour with salt and pepper, then dredge chicken to coat.

3. In a large skillet, heat olive oil over medium heat. Sear chicken for 3–4 minutes per side until golden (doesn’t need to be fully cooked). Transfer to baking dish.

4. In the same skillet, melt butter. Add mushrooms and sauté 5–6 minutes until tender.

5. In a bowl, mix cream of mushroom soup, broth, sour cream, garlic powder, and onion powder until smooth. Pour over chicken and mushrooms.

6. Top each piece of chicken with a slice of cheese.

7. Cover with foil and bake 25–30 minutes. Remove foil and bake 10 more minutes, or until cheese is melted and bubbly.

8. Garnish with parsley and serve warm.

Notes

• Great served over rice, egg noodles, or mashed potatoes.

• Use Gruyère for an extra flavorful cheese option.

• Can be assembled ahead and refrigerated until ready to bake.
