• Saucepan
• Wooden spoon or spatula
• 9×13 inch baking dish
• Measuring cups and spoons
• Knife and cutting board
• Aluminum foil

Instructions

• Preheat your oven to 375°F (190°C) so it’s ready once the dish is assembled.
• Bring a large pot of salted water to a boil and cook pasta until just al dente to prevent overcooking later.
• Drain the pasta thoroughly and set aside without rinsing so the sauce sticks better.
• Heat olive oil in a large skillet over medium heat.
• Add chopped onions and sauté for 2–3 minutes until soft and translucent.
• Stir in garlic and cook for about 30 seconds until fragrant.
• Add sliced mushrooms and cook until softened and lightly browned, allowing their moisture to evaporate.
• Add cooked chicken to the skillet and stir to combine with the mushrooms.
• Season with salt, pepper, Italian seasoning, and paprika for added depth.
• In a separate saucepan, melt butter over medium heat.
• Add flour and whisk continuously for 1–2 minutes to form a smooth roux.
• Slowly pour in milk while whisking to avoid lumps, creating a smooth sauce.
• Add heavy cream and continue stirring until the sauce thickens.
• Stir in half of the Parmesan cheese until melted and smooth.
• Combine the cooked pasta with the chicken and mushroom mixture.
• Pour the creamy sauce over everything and mix thoroughly until evenly coated.
• Lightly grease a baking dish and transfer the pasta mixture into it.
• Spread evenly and top with mozzarella cheese and remaining Parmesan.
• Cover loosely with foil to prevent the cheese from browning too quickly.
• Bake for 20 minutes until heated through.
• Remove foil and bake an additional 10–15 minutes until the top is golden and bubbly.
• Let the dish rest for 10 minutes before serving to allow it to set.
• Garnish with fresh parsley and serve warm.
