Tucked inside my grandmother’s 1972 recipe box was this handwritten gem — and after one bite, I understood why she kept it for so many years

This Oven-Baked 4-Ingredient Chicken Lombardy is creamy, cheesy, and full of rich mushroom flavor in every bite. Tender chicken breasts bake beneath a savory mushroom sauce and a layer of melted mozzarella, creating a comforting dinner that feels special without requiring much effort. Sautéing the mushrooms beforehand deepens their flavor and helps keep the sauce rich and hearty, while the cheese melts beautifully over the chicken for a perfectly cozy finish.

Easy Baked Chicken Lombardy

Ingredients

• 4 small chicken breasts (about 1½ lbs), patted dry
• 8 oz fresh mushrooms, sliced
• 1 can (10.5 oz) cream of mushroom soup
• 1½ cups shredded mozzarella cheese
• Salt and black pepper, to taste

Instructions

Step 1

Warm a small amount of butter or oil in a skillet over medium heat. Add the sliced mushrooms and cook for 6–8 minutes until softened and lightly browned.

Tip: Sautéing the mushrooms first helps remove excess liquid and gives the dish a deeper savory flavor.

Step 2

Preheat the oven to 375°F. Season the chicken breasts with salt and pepper, then arrange them in a lightly greased baking dish. Stir 2–3 tablespoons of water into the cream of mushroom soup to thin it slightly, then spread the soup mixture over the chicken.

Step 3

Spoon the cooked mushrooms and any flavorful juices from the skillet over the top of the chicken. Cover the dish loosely with foil and bake for 20 minutes.

Tip: The juices left in the skillet add extra richness to the sauce, so be sure to include them.

Step 4

Remove the foil and sprinkle the mozzarella cheese evenly over the chicken. Return the dish to the oven and bake uncovered for another 10–15 minutes, until the cheese is melted and bubbling and the chicken reaches an internal temperature of 165°F.

Optional: Broil for 1–2 minutes at the end for a lightly golden cheesy topping.

Step 5

Allow the dish to rest for about 5 minutes before serving so the sauce can settle and thicken slightly.
