Comforting Cheesy Chicken Casserole Recipe

Assembling the Casserole

1. Slice the Chicken. Transfer the seared breasts to a cutting board and cut them into bite‑size cubes. This ensures even distribution of protein throughout the casserole and speeds up the final baking time.
2. Mix the Veggies. In a large bowl combine broccoli florets, diced red bell pepper, and the melted butter. Toss gently so the vegetables are lightly coated—this prevents them from drying out during baking.
3. Whisk the Custard. In a separate mixing bowl, whisk together eggs, milk, heavy cream, half of the grated cheddar, and a pinch of salt and pepper. The custard should be smooth and slightly frothy; this aeration creates a light, airy texture once baked.
4. Layer the Dish. Spread the butter‑tossed vegetables evenly in a greased 9×13‑inch baking dish. Distribute the cubed chicken over the veg, then pour the custard mixture across the top, allowing it to seep into every crevice.
5. Add the Cheese & Topping. Sprinkle the remaining cheddar, mozzarella, and panko breadcrumbs over the surface. Drizzle the melted butter once more to help the breadcrumbs turn golden and crisp.

Baking & Finishing

Place the assembled dish in the preheated oven and bake for 25‑30 minutes, or until the custard is set (a knife inserted in the center should come out clean) and the topping is a deep golden brown. Remove from the oven, let the casserole rest for 5‑7 minutes, then sprinkle fresh parsley for a bright finish. Serve warm, and enjoy the comforting blend of cheesy goodness and tender chicken.
