Nope! Once you’ve made the sauce, all you have to do is chop up the raw chicken and broccoli, then combine it with the rice and sauce. Then, you’ll place it all in the casserole dish, cover with a tight-fitting lid or aluminum foil, and cook for 45 minutes. After 45 minutes, you’ll remove the lid from the pot and sprinkle the cheese over, then bake for another 15 minutes to let it melt.
