Chicken Divine Bake

Step 1
Bring a large saucepan of lightly salted water to a boil. Cook chicken in boiling water until no longer pink in the center and the juices run clear, about 30 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Remove chicken to a cutting board to cool, then shred.

Step 2
Preheat the oven to 400 degrees F (200 degrees C).

Step 3
Steam broccoli in the microwave according to package directions until crisp-tender, 4 to 6 minutes.

Step 4
Stir condensed soup and mayonnaise together in a bowl; add broccoli, onion, and mushrooms and stir to coat.

Step 5
Spread cooked rice into the bottom of a casserole dish. Top rice with shredded chicken. Spread soup mixture over chicken, then sprinkle with Cheddar.

Step 6
Bake in the preheated oven until slightly browned on top, 35 to 45 minutes.
