Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Chicken breast: Boneless, skinless chicken breasts are ideal for this bake. They cook up tender and juicy beneath the creamy sauce.

Spinach: Fresh baby spinach adds color, nutrition, and a touch of freshness that balances the richness of the dish.

Mushrooms: Cremini or button mushrooms bring a deep, earthy flavor that pairs perfectly with the creamy sauce.

Onion: Sautéed onions form a flavorful base that enhances the sweetness of the mushrooms.

Garlic: Adds a warm, aromatic note and depth to the sauce.

Olive oil: Used for sautéing vegetables and keeping the chicken moist.

Butter: Combined with flour to create a roux, forming the creamy sauce’s foundation.

All-purpose flour: Helps thicken the sauce to the perfect consistency.

Chicken broth: Adds savory depth to the cream sauce and keeps the dish light.

Heavy cream: Gives the sauce its rich, velvety texture that coats every bite.

Mozzarella cheese: Melts beautifully and creates that satisfying cheesy top layer.

Parmesan cheese: Adds a nutty, salty finish that enhances the overall flavor.

Salt and black pepper: Classic seasonings that balance all the rich elements.

Paprika: A sprinkle adds warmth and a hint of smokiness to the dish.

Parsley: Fresh parsley brings a bright finishing touch and a burst of color.

Directions

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

Heat olive oil in a large skillet over medium heat. Add the onions and sauté until translucent. Add mushrooms and cook until they’re golden brown and the liquid has evaporated. Stir in the garlic and cook for 30 seconds more. Add spinach and cook until wilted. Remove the mixture from the skillet and set aside.

In the same skillet, melt butter over medium heat. Stir in the flour and cook for 1 minute to create a roux. Gradually whisk in chicken broth and heavy cream until smooth. Season with salt, pepper, and paprika. Simmer for 2–3 minutes until the sauce thickens slightly.

Layer the chicken breasts in the prepared baking dish. Pour the creamy sauce evenly over the chicken, then top with the spinach and mushroom mixture. Sprinkle mozzarella and Parmesan cheese over the top.

Bake uncovered for 25–30 minutes, or until the chicken is cooked through and the cheese is melted and bubbly. Garnish with fresh parsley before serving.
