Step-by-Step Instructions

Preheat the oven Set your oven to 375°F. This temperature allows the casserole to cook evenly and develop a golden, bubbly top.
Prepare the chicken If using raw chicken, cut it into bite-sized pieces. If using pre-cooked chicken, shred or cube it for easy mixing.
Blanch or prep broccoli Lightly steam or blanch the broccoli for a few minutes. This ensures it becomes tender in the oven without turning mushy.
Make the creamy base In a bowl, combine heavy cream and cream cheese. Mix until smooth and thick. This forms the rich base of the casserole.
Combine everything Add chicken and broccoli into the mixture. Stir well so everything is evenly coated.
Transfer to baking dish Pour the mixture into a casserole dish and spread it evenly.
Add cheese on top Sprinkle cheddar cheese generously over the top for that golden crust.
Bake until bubbly Bake for 25–30 minutes until the cheese is melted and slightly golden, and the chicken is fully cooked.
Rest before serving Let it sit for a few minutes before serving so the sauce thickens properly.
