Make this comforting, low-carb chicken cauliflower rice casserole for an easy weeknight meal. It is cheesy, creamy, and a satisfying gluten-free alternative to traditional rice bakes.

Ingredients

Scale
  • 3 cups cooked chicken breast, shredded or diced
  • 4 cups cauliflower rice (fresh or frozen)
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 1 cup broccoli florets, cut small
  • 8 oz cream cheese, softened
  • 1 cup shredded cheddar cheese, divided
  • 1/2 cup chicken broth
  • 1/4 cup heavy cream or half-and-half
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  2. In a large skillet over medium heat, sauté the diced onion until soft, about 5 minutes. Add the minced garlic and cook for 1 minute more until fragrant.
  3. Add the cauliflower rice and broccoli florets to the skillet. Cook, stirring occasionally, until the vegetables have softened slightly, about 5-7 minutes.
  4. Stir in the shredded chicken, cream cheese, chicken broth, and heavy cream into the skillet mixture. Cook until the cream cheese is fully melted and the mixture is combined.
  5. Remove the skillet from the heat. Stir in the salt, pepper, and half (1/2 cup) of the shredded cheddar cheese. Mix well.
  6. Transfer the entire mixture to your prepared baking dish.
  7. Sprinkle the remaining 1/2 cup of cheddar cheese evenly over the top of the casserole.
  8. Bake for 20 to 25 minutes, or until the casserole is bubbly and the cheese on top 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 less rich.
  • If you use frozen cauliflower rice, make sure to thaw and drain off any excess water before adding it to the skillet.
  • This recipe works well for meal prep; cover and refrigerate leftovers for up to 4 days.
