Ingredients

Scale
  • 3 cups cooked chicken, shredded or diced
  • 4 cups cauliflower rice (fresh or frozen)
  • 1 tablespoon olive oil
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 8 ounces cream cheese, softened
  • 1 cup chicken broth
  • 1 cup heavy cream
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon dried Italian seasoning
  • 1 cup shredded cheddar cheese, divided
  • 1/2 cup shredded mozzarella cheese
  • 1/2 cup broccoli florets (optional)

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. If using frozen cauliflower rice, thaw it first and press out any excess moisture using a paper towel or clean cloth.
  3. Heat the olive oil in a large skillet over medium heat. Add the diced onion and cook until soft, about 5 minutes. Add the minced garlic and cook for 1 minute more until fragrant.
  4. Add the cauliflower rice and optional broccoli florets to the skillet. Cook, stirring occasionally, for 5 to 7 minutes until the cauliflower rice softens slightly.
  5. Reduce the heat to low. Stir in the softened cream cheese until it melts smoothly into the vegetables.
  6. Pour in the chicken broth and heavy cream. Stir well to combine. Season with salt, pepper, and Italian seasoning.
  7. Remove the skillet from the heat. Stir in the shredded chicken and 1/2 cup of the cheddar cheese until everything is evenly coated in the creamy sauce.
  8. Transfer the mixture to your prepared baking dish.
  9. Top the casserole evenly with the remaining 1/2 cup cheddar cheese and all of the mozzarella cheese.
  10. Bake for 20 to 25 minutes, or until the casserole is bubbly and the cheese topping is melted and lightly golden brown.
  11. Let the casserole rest for 5 minutes before you serve it.

Notes

  • For an even quicker meal, use rotisserie chicken.
  • If you prefer a thicker sauce, reduce the chicken broth slightly before adding it.
  • This recipe is excellent for meal prep; cover and refrigerate leftovers for up to 4 days.
