3 cups prepared stuffing
2 cups cubed cooked chicken
2 cups broccoli florets
1 (12 ounce) jar chicken gravy
1 cup shredded Cheddar cheese, divided
Preheat oven to 350 degrees F (175 degrees C). Grease an 8×8-inch baking pan.
Mix stuffing, chicken, broccoli, chicken gravy, and half the Cheddar cheese in a large bowl. Spread into the prepared baking pan; sprinkle with remaining Cheddar cheese.
Bake in the preheated oven until cooked through and Cheddar cheese is melted, 20 to 25 minutes.
