- 2 lbs chicken breast, cut into bite-sized pieces
- 4 cups broccoli florets
- 1 1/2 cups heavy cream

Instructions
Assembly Phase
- Prepare the BasePreheat the oven to 375°F (190°C). In a large mixing bowl, combine the bite-sized chicken breast pieces with the broccoli florets. Ensure the chicken and broccoli are evenly distributed before transferring the mixture into a 9x13 baking dish. Arrange the pieces in an even layer to ensure consistent cooking throughout the casserole.Look for The chicken and broccoli should be well mixed and spread evenly in the dish.Tip Cut the broccoli into uniform florets to ensure they cook at the same rate as the chicken.
At the end of this phase, the chicken and broccoli should be evenly distributed in the baking dish. Everything should look clean and ready for the cream. Check that all chicken pieces are cut to a uniform size to ensure consistent cooking and that the broccoli is evenly spaced among the meat.
Baking Phase
- Add Cream and BakePour the heavy cream over the chicken and broccoli mixture, ensuring it coats everything thoroughly. Place the dish in the preheated oven and bake for 30 minutes. Monitor the progress to ensure the cream begins to thicken and the chicken cooks through to an internal temperature of 165°F (74°C).Look for The sauce should be bubbling and slightly thickened around the edges of the dish.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Avoid overfilling the dish to prevent the cream from bubbling over in the oven.
The casserole should look creamy and smell fragrant as the chicken cooks in the heavy cream. The sauce will be bubbling and thickening around the edges of the dish.
Verify that the chicken is cooked through by checking the internal temperature before proceeding to the final step of adding the cheese.
Finishing Phase
- Add Cheese and FinishRemove the baking dish from the oven and carefully sprinkle the shredded cheddar cheese over the top in an even layer. Return the dish to the oven for an additional 5 minutes or until the cheese is completely melted and golden brown. Remove from the oven, garnish with fresh chopped parsley, and let it rest for 10 minutes before serving.Look for The cheese should be melted, bubbly, and golden brown on top.Tip Broil for the last minute if a darker, crispier cheese crust is desired.
The dish is complete when the cheese is melted, bubbly, and golden brown. The aroma should be rich and savory. Ensure the dish has rested for the required ten minutes before serving to allow the sauce to achieve its perfect, velvety consistency for the best possible eating experience.
Common mistakes
Avoid overcrowding the baking dish, as this can lead to uneven cooking and may prevent the cream from bubbling properly. Ensure the chicken pieces are cut to a similar size to avoid having some pieces overcooked while others remain undercooked.
Finally, do not rush the resting period, as this time allows the sauce to settle and the flavors to fully distribute, resulting in a better texture when serving.
How to tell it’s done
The casserole is considered done when the chicken reaches an internal temperature of 165°F (74°C). You can check this by inserting a food thermometer into the thickest piece of chicken.
Additionally, the sauce should be visibly bubbling throughout the dish, and the cheese topping should be melted and golden brown, indicating that the flavors have properly developed and the ingredients are cooked through.
