How to Make Mouthwatering Cheesy Chicken Riced Cauliflower Casserole

  1. Preheat: Set your oven to 375°F (190°C) and generously grease a 9x13-inch baking dish to ensure a non-stick surface for that cheesy goodness.
  2. Season: Pat the chicken breasts dry. Sprinkle with garlic powder, onion powder, paprika, Italian herbs, salt, and black pepper, coating them evenly for maximum flavor.
  3. Sear: Heat avocado oil in a skillet over medium-high heat. Sear chicken for 4-5 minutes on each side until golden brown, sealing in the juices.
  4. Bake: Transfer the seared chicken to an oven-safe dish and bake for 15-20 minutes until the internal temperature reaches 165°F (74°C). This ensures the chicken is perfectly cooked.
  5. Rest: Let the chicken rest for 5-10 minutes after baking. Then shred or dice it into bite-sized pieces for mixing.
  6. Rice: Use a food processor or box grater to rice your cauliflower until it’s uniform in texture, perfect for absorbing all the delicious flavors.
  7. Sauté: In the same skillet, heat oil or butter over medium heat. Add the riced cauliflower with water (if using), salt, and pepper, sauté for 7-10 minutes until tender-crisp.
  8. Dry: If there’s excess moisture, gently pat the cauliflower with a kitchen towel to avoid a watery casserole.
  9. Make Sauce: Melt butter in a saucepan over medium heat, whisk in flour to create a roux, cooking for 1-2 minutes until golden.
  10. Whisk: Gradually whisk in warmed milk and chicken broth, stirring until the sauce thickens, about 3-5 minutes, creating a creamy base.
  11. Incorporate: Add cream cheese, Dijon mustard, and seasonings. Whisk until smooth and everything is well combined.
  12. Combine: In a mixing bowl, fold together the shredded chicken, sautéed riced cauliflower, and two-thirds of the cheese sauce, gently mixing to keep it fluffy.
  13. Transfer: Spread the mixture evenly in the greased baking dish, ensuring every bite is loaded with flavor.
  14. Top: Pour the remaining cheese sauce over the casserole and sprinkle additional cheese on top for an extra cheesy layer.
  15. Bake Again: Bake for 25-30 minutes until bubbly and golden brown. If the top browns too quickly, tent it with foil.
  16. Broil: For a crunchy topping, broil for 2-3 minutes. Keep a watchful eye to prevent burning!
  17. Rest: Remove the casserole from the oven and let it rest for 10-15 minutes to allow flavors to meld beautifully before serving.
  18. Garnish: Optional but delightful — sprinkle fresh herbs on top for a burst of color and freshness.

💡 Pro Tip: For an extra layer of flavor, consider adding crumbled bacon on top before baking — it adds a delicious crunch!
