Step 1

Preheat the oven to 400F. Spray the inside of a 9 by 13-inch casserole dish with nonstick cooking spray.

Step 2

Fill a 3-quart saucepan about halfway full with water. Bring to a boil and generously salt the water. Add the broccoli and boil for 90 seconds. Drain immediately.

Step 3

Spread the chicken out evenly into the prepared casserole dish. Spread the broccoli on top of the chicken, and sprinkle the cheddar on top. Pour the soup on top, spreading it out. Sprinkle on the panko, and then drizzle on the butter.

Step 4

Cover the casserole with foil and bake until warm throughout, about 20 minutes.

Step 5

Remove the foil and broil briefly to brown the top.

Step 6

Sprinkle on the parsley and serve.
