How to Make Chicken Lombardy

Step 1: Prepare the Oven

Preheat your oven to 375°F (190°C). Lightly grease a baking dish.

Step 2: Season the Chicken

Season both sides of the chicken breasts with salt and pepper. Arrange them in a single layer in the baking dish.

Step 3: Cook the Mushrooms

Heat butter or oil in a skillet over medium heat. Add sliced mushrooms and sauté until browned and tender, about 6–8 minutes.

Step 4: Make the Creamy Sauce

In a bowl, stir the cream of mushroom soup with a few tablespoons of water until smooth and spreadable.

Step 5: Assemble the Casserole

Spread the creamy mushroom sauce over the chicken. Top with sautéed mushrooms.

Step 6: Bake

Cover loosely with foil and bake for 20 minutes.

Step 7: Add the Cheese

Remove foil and sprinkle mozzarella cheese evenly over the top.

Step 8: Finish Baking

Bake uncovered for another 10–15 minutes until the cheese is melted and golden and the chicken reaches 165°F internally.

Let rest for 5 minutes before serving.
