Prep: 15 mins
Cook: 40 mins
Total: 55 mins


  • 14 oz cauliflower florets, cut into bite-size pieces
  • 32 oz chicken breast
  • 1 tsp onion powder
  • 1 tsp garlic powder
  • ½ tsp salt
  • ¼ tsp pepper
  • 1 tbsp olive oil
  • 2 cups *Alfredo Sauce, (see Recipe Notes for recipe)
  • 12 oz mozzarella cheese, shredded, divided


  1. Steam the cauliflower. Place cut cauliflower in a microwave-safe bowl with 1 cup of water. Cover with a damp paper towel and microwave on High for approximately 3 to 5 minutes or until the cauliflower is fork-tender. Don’t overcook.

  2. Drain the cauliflower pat dry with a paper towel. Set aside.
  3. Cut the chicken breast into 1-inch cubes and sprinkle with onion powder, garlic powder, salt, and pepper.
  4. In a skillet over medium-high heat add the olive oil and the cubed chicken. Cook for approximately 10 minutes, or until chicken is cooked through. Set aside.

  5. Preheat oven to 350 degrees F.
  6. In a small pot heat the alfredo sauce over medium-low heat. When it is hot add 3 ounces of mozzarella cheese to the sauce and stir until it is melted and the sauce is smooth.

  7. Prepare a 13x9-inch casserole dish by spraying it with non-stick spray then spread ½ cup of alfredo sauce on the bottom.

  8. Next, add ½ of the cauliflower to the dish making a layer of it on the bottom.

  9. Top with ½ of the cooked chicken. Let the chicken fill in the spaces between the cauliflower to fill the dish.

  10. Pour ¾ cup of alfredo sauce over the cauliflower and chicken.

  11. Sprinkle 4½ ounces of mozzarella on top.

  12. Repeat steps using the remaining cauliflower and chicken to make a layer, followed by the remaining alfredo sauce, and topped with the last of the mozzarella cheese.

  13. Place in oven and bake for 30 minutes, or until the casserole is warmed through and the cheese is fully melted.
