Ingredients

Scale
  • 3 cups shredded chicken (use rotisserie chicken for speed)
  • 4 cups cauliflower rice (frozen or fresh)
  • 8 oz cream cheese, softened
  • 1 cup shredded cheddar cheese, divided
  • 1/2 cup chicken broth
  • 1/2 cup heavy cream or half-and-half
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon salt
  • 1 cup steamed broccoli florets (optional, for added vegetables)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  2. If using frozen cauliflower rice, thaw it slightly and squeeze out any excess moisture using a clean kitchen towel or paper towels. This step is important for a creamy texture.
  3. In a large bowl, combine the softened cream cheese, chicken broth, heavy cream, garlic powder, onion powder, salt, and pepper. Whisk until the mixture is smooth and creamy.
  4. Fold in the shredded chicken, cauliflower rice, and broccoli florets (if using) into the cream cheese mixture until everything is evenly coated.
  5. Stir in 3/4 cup of the shredded cheddar cheese into the mixture.
  6. Spread the entire mixture evenly into your prepared baking dish.
  7. Top the casserole evenly with the remaining 1/4 cup of shredded cheddar cheese.
  8. Bake for 25 to 30 minutes, or until the casserole is heated through and the cheese topping is melted and lightly golden brown.
  9. Let the casserole rest for 5 minutes before you serve it.

Notes

  • For a lighter version, substitute the cream cheese with plain Greek yogurt, though the texture will be slightly less rich.
  • If you want to make this a gluten-free chicken bake, confirm all your ingredients, like broth, are certified gluten-free.
  • This recipe works well for meal prep; cover and refrigerate leftovers for up to 3 days.
