Ingredients

  • 4 cups broccoli florets
  • ½ cup cream cheese softened
  • 2 tbsp mayonnaise
  • ½ cup grated cheddar cheese
  • ½ tsp garlic powder
  • ¼ tsp sea salt
  • ¼ tsp black pepper
  • 1 ½ cups cooked chicken chopped
  • ¼ cup grated cheese for topping the casserole

Instructions

Preheat the oven.

  • Preheat the oven to 375°F. Grease a 9 x 9-inch casserole dish with nonstick cooking spray and set aside.

Prepare the broccoli.

  • Place a large saucepan with approximately 2 inches of water over medium-high heat. Bring the water to a rolling boil.

Steam the broccoli.

  • Add the broccoli florets to the saucepan. Steam for approximately 2 minutes, or until the broccoli is fork tender.

Drain the broccoli.

  • Drain the water from the saucepan. Return the broccoli to the pan and set aside.

Prepare the creamy base.

  • In a large mixing bowl, combine the softened cream cheese and mayonnaise. Stir until smooth and well blended.

Add the seasonings.

  • Stir in the garlic powder, sea salt, and black pepper until evenly incorporated.

Add the cheddar cheese.

  • Add ½ cup grated cheddar cheese to the cream cheese mixture and stir until combined.

Add the chicken.

  • Add the chopped cooked chicken to the mixing bowl. Stir until the chicken is evenly coated with the creamy mixture.

Add the broccoli.

  • Add the steamed broccoli to the bowl. Gently stir until the broccoli, chicken, cheese, and creamy mixture are evenly combined.

Transfer to the casserole dish.

  • Pour the chicken and broccoli mixture into the prepared casserole dish. Spread it into an even layer.

Add the topping.

  • Sprinkle the remaining ¼ cup grated cheese evenly over the top of the casserole.

Bake the casserole.

  • Bake for 15 minutes, or until the casserole is heated through and the cheese begins to melt.

Broil the topping.

  • Set the oven to broil. Broil for 2 to 3 minutes, or until the cheese is bubbling and lightly browned in spots.

Serve.

  • Remove the casserole from the oven and serve warm.
