Ingredients Equipment Method Notes

Ingredients
  

  • 4 cups cooked chicken shredded or diced
  • 5 cups cauliflower florets about 1 medium head
  • 8 oz cream cheese softened
  • 1/2 cup heavy cream
  • 1.5 cups shredded cheddar cheese divided
  • 1 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/2 tsp salt or to taste
  • 1/4 tsp black pepper or to taste

Equipment

  • 1 9x13 inch Baking Dish
  • 1 Saucepan
  • 1 Large Mixing Bowl

Instructions
 

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
  2. Place cauliflower florets in a large, microwave-safe bowl with 2 tablespoons of water. Cover and microwave for 5-7 minutes, or until tender-crisp. Drain all excess water very well.
  3. In a medium saucepan over medium heat, combine the softened cream cheese and heavy cream. Stir frequently until the cream cheese is fully melted and the mixture is smooth.
  4. Stir in the garlic powder, onion powder, salt, and pepper. Reduce the heat to low and add 1 cup of the shredded cheddar cheese. Stir until the cheese is melted and the sauce is creamy.
  5. In a large bowl, combine the cooked chicken and the steamed, drained cauliflower. Pour the cheese sauce over the top and stir gently to coat everything evenly.
  6. Transfer the mixture to the prepared baking dish and spread it into an even layer. Sprinkle the remaining 1/2 cup of cheddar cheese over the top.
  7. Bake for 20-25 minutes, or until the casserole is hot and bubbly and the cheese topping is golden brown.
  8. Let the casserole cool for 5-10 minutes before serving. This helps it set.

Notes

Tip 1: For the best texture, shred your own cheese. Pre-shredded varieties contain additives that can make the sauce grainy.
Tip 2: Ensure the cauliflower is drained very well after steaming to prevent a watery casserole.
Tip 3: Rotisserie chicken is a great time-saver for this recipe.
