Step 6

Add the salt and pepper and remove the saucepan from the heat.

Step 7

Add 1 cup of the shredded cheddar, stirring until smooth.

Step 8

Add in the broccoli.

Step 9

While the sauce is cooking, spray a 9x13-inch baking dish with cooking spray.

Step 10

Combine the chicken and rice in the prepared dish.

Step 11

Add the sauce mixture to the rice and chicken mixture, stirring to combine.

Step 12

Sprinkle the top of the casserole with the shredded parmesan and the remaining 1/2 cup of the cheddar cheese.
