Ingredients
(Note: the full ingredients list, including measurements, is provided in the recipe card directly below.)
Here’s what makes this bake so irresistibly creamy and flavorful. Each ingredient plays a key role:
Chicken Breast
Tender and lean, chicken breast soaks up the creamy sauce, adding protein and heartiness to the dish.
Mushrooms
Cremini or button mushrooms bring an earthy, umami depth that pairs perfectly with the creamy sauce.
Butter
Creates a rich base for the sauce and adds a touch of indulgence to the dish.
All-Purpose Flour
Thickens the sauce, giving it that velvety, stick-to-your-spoon texture.
Chicken Broth
Adds savory depth to the sauce, enhancing the chicken flavor without overpowering the dish.
Heavy Cream
The secret to that luxurious, creamy sauce that makes every bite feel decadent.
Garlic
Minced garlic adds a warm, aromatic note that complements the mushrooms and chicken.
Parmesan Cheese
Grated Parmesan brings a nutty, salty kick to the sauce and a melty topping that’s pure bliss.
Mozzarella Cheese
Shredded mozzarella creates a gooey, golden crust on top, because who can resist melted cheese?
Onion
Diced onion adds a subtle sweetness and depth to the sauce, balancing the richness.
Thyme
Fresh or dried thyme brings a delicate, herby note that ties all the flavors together.
Breadcrumbs
Mixed with butter, they create a crispy, golden topping that contrasts beautifully with the creamy filling.
Instructions
Let’s get cooking! Here’s how to make this comforting bake:
Preheat Your Equipment
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish to ensure easy serving and cleanup.
Prepare the Chicken
Season chicken breasts with salt and pepper. In a large skillet, heat a bit of butter over medium heat and cook chicken for 3-4 minutes per side until golden but not fully cooked. Set aside to rest, then slice or cube.
Cook the Mushrooms
In the same skillet, add more butter and sauté diced onion until soft, about 3 minutes. Add sliced mushrooms and cook for 5-7 minutes until they release their juices and turn golden. Stir in minced garlic and thyme for the last minute.
Make the Creamy Sauce
Sprinkle flour over the mushrooms and stir for 1-2 minutes to form a roux. Gradually whisk in chicken broth and heavy cream, stirring until smooth and thickened, about 5 minutes. Stir in Parmesan cheese until melted. Season with salt and pepper to taste.
Combine Ingredients
In a large bowl, mix the sliced chicken with the creamy mushroom sauce. If you want extra veggies, toss in some spinach or broccoli here. Pour the mixture into the prepared baking dish, spreading it evenly.
Add the Topping
Sprinkle shredded mozzarella over the top, followed by breadcrumbs mixed with a little melted butter for that crispy, golden finish.
Bake to Perfection
Bake for 25-30 minutes, until the casserole is bubbly and the topping is golden brown. If you want extra crispiness, broil for 1-2 minutes at the end (watch closely!).
Finishing Touches
Let the bake cool for 5 minutes before serving. This helps the sauce set slightly for easier scooping.
Serve and Enjoy
Scoop generous portions onto plates and serve hot. Pair with a side salad, mashed potatoes, or crusty bread for a complete meal.
