Comforting Cheesy Chicken Casserole Recipe

Ingredients

Main Ingredients

• 4 boneless, skinless chicken breasts (about 1½ lbs)
• 1 cup broccoli florets, chopped
• ½ cup red bell pepper, diced
• 2 tablespoons unsalted butter, melted

Custard & Cheese

• 4 large eggs
• 1 cup whole milk
• ½ cup heavy cream
• 1 cup sharp cheddar cheese, grated
• ½ cup mozzarella cheese, shredded

Seasonings & Topping

• 1 teaspoon garlic powder
• ½ teaspoon smoked paprika
• Salt and freshly ground black pepper, to taste
• ¼ cup panko breadcrumbs
• 1 tablespoon fresh parsley, chopped (optional)

Instructions

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.
