Ingredients
  

  • 2 cups cooked chicken shredded (rotisserie chicken works great)
  • 2 cups broccoli florets fresh or thawed frozen
  • 1 cup cheddar cheese shredded (sharp cheddar preferred)
  • 1 cup heavy cream
  • 1/2 cup cream cheese softened
  • 1/2 cup Parmesan cheese grated
  • 1 tablespoon olive oil for greasing dish
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon paprika
  • 1/2 teaspoon salt adjust to taste
  • 1/4 teaspoon black pepper freshly ground

Instructions
 

  • Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish with olive oil.
  • Steam broccoli florets for 3-4 minutes until bright green but still crisp.
  • In a saucepan over low heat, whisk together heavy cream and softened cream cheese until smooth.
  • Stir in garlic powder, onion powder, paprika, salt, and pepper.
  • Remove from heat and stir in half of the shredded cheddar cheese until melted.
  • In a large mixing bowl, combine shredded chicken, steamed broccoli, and cheese sauce, mixing gently to coat.
  • Transfer the mixture to the prepared baking dish and spread evenly.
  • Top with remaining cheddar cheese and all the Parmesan cheese.
  • Bake for 25-30 minutes, until the cheese is melted and golden.
  • Let the casserole rest for 5 minutes before slicing and serving.

Notes

Add crispy bacon bits or swap half the broccoli for cauliflower for variation.
For a dairy-free version, substitute coconut cream for heavy cream and use nutritional yeast instead of cheese.
Store leftovers in the fridge for up to 4 days; reheat individual portions in the microwave or oven.
