Ingredients

Chicken breasts: Two large, sliced chicken breasts provide tender, juicy protein as the dish’s hearty base.
Zucchini: Two medium zucchinis, thinly sliced, add fresh, slightly sweet flavor and moisture.
Mushrooms: Two cups of sliced mushrooms contribute earthy depth and meaty texture.
Onion: One small chopped onion brings subtle sweetness and aromatic flavor throughout.
Garlic: Three cloves minced garlic create a fragrant, savory foundation balancing the rich sauce.
Olive oil: One tablespoon of olive oil is used for sautéing, lending a smooth richness to the veggies and chicken.
Salt & black pepper: To taste, seasoning key ingredients for balanced flavor enhancement.
Paprika: Half a teaspoon adds mild smoky warmth and vibrant color to the chicken.
Italian seasoning: Half a teaspoon of herbs adds savory complexity and compliments the creamy elements.
Heavy cream: One cup creates a luscious, velvety base for the creamy sauce enveloping the chicken and veggies.
Chicken broth: Half a cup adds moisture and depth, balancing the richness of the cream.
Parmesan cheese: Half a cup grated Parmesan provides salty, nutty flavor that enriches the sauce.
Mozzarella cheese: One cup shredded mozzarella melts on top, forming a golden bubbly crust.
Red pepper flakes (optional): Half a teaspoon for a subtle kick, great for those who enjoy a bit of heat.

Instructions

Preheat and Prepare: Preheat your oven to 375°F (190°C) and lightly grease a baking dish. This ensures the casserole doesn’t stick and the heat is ready to finish the dish perfectly baked and bubbly.
Sear the Chicken: In a large skillet, heat the olive oil over medium-high heat. Add the sliced chicken breasts and cook for 3 to 4 minutes until they develop a light golden color. This initial searing locks in moisture and starts building flavor before baking.
Season the Chicken: Sprinkle salt, black pepper, paprika, and Italian seasoning evenly over the chicken. These spices boost the flavor profile, providing a balance of saltiness, gentle heat, and herbal notes.
Sauté the Vegetables: Add the chopped onion, sliced mushrooms, zucchini, and minced garlic to the pan. Cook for about 4 minutes until the vegetables start to soften but remain vibrant. This step enhances their natural sweetness and texture while blending flavors.
Create the Creamy Sauce: Pour in the heavy cream and chicken broth, stirring well. Let the mixture simmer gently for 2 minutes to thicken slightly. Then, stir in the grated Parmesan cheese until melted and incorporated, making a rich, flavorful sauce that coats every ingredient.
Assemble the Bake: Transfer the chicken and vegetable mixture into the greased baking dish. Evenly spread the creamy sauce and top with shredded mozzarella. The mozzarella will melt and brown during baking, adding a deliciously gooey layer on top.
Bake Until Golden: Bake the dish in the preheated oven for 20 to 25 minutes until the cheese is bubbly and golden brown. Baking melds the flavors together and ensures the chicken is fully cooked and juicy.
Rest and Serve: Remove the dish from the oven and let it rest for 5 minutes. This allows the sauce to thicken slightly and makes serving easier. Serve warm with rice, pasta, or garlic bread to enjoy every creamy bite.
