Ingredients

• 4 cups cooked, shredded chicken (about 2 large breasts)
• 2 cups marinara sauce (store‑bought or homemade)
• 1 ½ cups shredded mozzarella cheese
• ½ cup grated Parmesan cheese
• 1 cup Italian seasoned breadcrumbs
• 2 Tbsp unsalted butter, melted
• 1 tsp garlic powder
• ½ tsp dried oregano
• Salt & pepper to taste
• Fresh basil leaves for garnish (optional)

Step‑by‑Step Instructions

1. Preheat the oven to 200 °C (400 °F). Lightly grease a 9×13‑inch (23×33 cm) baking dish with cooking spray or a thin layer of olive oil.
2. Combine the chicken and sauce: In a large bowl, toss the shredded chicken with the marinara sauce, half of the mozzarella, and half of the Parmesan. Season with salt, pepper, garlic powder, and dried oregano. Mix until evenly coated.
3. Transfer to the dish: Spread the chicken‑sauce mixture evenly across the prepared baking dish, smoothing the top with a spatula.
4. Prepare the crunchy topping: In a small bowl, combine the breadcrumbs, melted butter, remaining mozzarella, and remaining Parmesan. Stir until the crumbs are lightly coated with butter.
5. Layer the topping: Sprinkle the breadcrumb mixture over the chicken layer, ensuring an even coverage for a uniform golden crust.
6. Bake for 20‑25 minutes, or until the topping is golden brown and the sauce is bubbling around the edges.
7. Rest briefly: Remove the casserole from the oven and let it sit for 5 minutes. This helps the sauce set and makes slicing cleaner.
8. Garnish & serve: Sprinkle fresh basil leaves on top for a pop of color and aroma. Cut into squares and serve hot.
9. Optional side suggestions: Pair with a simple arugula salad, garlic‑bread, or roasted vegetables for a complete meal.

Pro Tips & Tricks

• Use rotisserie chicken for an even faster prep—just shred and go.
• Dry the breadcrumbs slightly in a dry skillet before mixing with butter for extra crunch.
• Layer extra cheese on top of the breadcrumbs if you love a super‑cheesy crust.
• Mix fresh herbs (like chopped parsley or basil) into the sauce for brighter flavor.
• Don’t over‑bake—keep an eye on the crust; it should be golden, not burnt.

Storage Tips

Allow the casserole to cool completely before storing. Transfer leftovers to an airtight container and refrigerate for up to 4 days. To reheat, cover with foil and bake at 175 °C (350 °F) for 15‑20 minutes, or microwave individual portions for 2‑3 minutes, adding a splash of water to keep the sauce from drying out.

This dish also freezes beautifully. Portion into freezer‑safe containers, label, and freeze for up to 3 months. Thaw overnight in the fridge, then bake as directed, adding an extra 5 minutes if needed to achieve a crisp topping.
