Step‑by‑Step Instructions for Cheesy Chicken Riced Cauliflower Casserole

Step 1: Preheat Oven and Prepare Baking Dish
Preheat your oven to 375°F (190°C) while you prepare a 9×13-inch baking dish by greasing it lightly with cooking spray or avocado oil. This step ensures your Cheesy Chicken Riced Cauliflower Casserole won’t stick after baking, making it easy to serve and enjoy.

Step 2: Sear the Chicken
Season your boneless, skinless chicken breasts with kosher salt and ground black pepper. In a skillet, heat a tablespoon of avocado oil over medium-high heat. Sear the chicken for 4-5 minutes on each side until golden brown and cooked through, creating a delicious crust that enhances the flavor of the casserole.

Step 3: Bake and Shred Chicken
Transfer the seared chicken to the preheated oven and bake for 15-20 minutes or until it reaches an internal temperature of 165°F (74°C). Once cooked, remove it from the oven and allow it to rest for a few minutes before shredding the chicken into bite-sized pieces with two forks, ready to be mixed into your casserole.

Step 4: Sauté the Riced Cauliflower
In the same skillet, add another tablespoon of avocado oil and heat over medium flame. Add the frozen riced cauliflower and sauté for 7-10 minutes until it’s tender-crisp and most of the moisture has evaporated. This technique enhances texture in your Cheesy Chicken Riced Cauliflower Casserole, making it hearty without being watery.

Step 5: Make the Cheese Sauce
In a separate saucepan, melt a bit of butter over medium heat and whisk in equal parts of flour to create a roux. Gradually pour in warmed milk while continuously whisking until the mixture thickens. This creamy sauce will be the dreamy base for your casserole, infusing each bite with comforting flavors.

Step 6: Add Flavor to the Sauce
Once your roux has thickened, incorporate the softened cream cheese, Dijon mustard, garlic, garlic powder, and Italian seasoning into the mixture. Stir until smooth and melted, then slowly fold in your desired cheese blend until everything is well combined and gooey; this flavorful sauce will elevate your Cheesy Chicken Riced Cauliflower Casserole.

Step 7: Combine Chicken and Cauliflower
In a large mixing bowl, combine the shredded chicken with sautéed riced cauliflower. Pour in two-thirds of the cheese sauce, mixing gently until everything is evenly coated. This blend of ingredients creates a mouthwatering filling, central to your comforting casserole.

Step 8: Assemble the Casserole
Transfer the chicken and cauliflower mixture into the prepared baking dish, spreading it evenly. Pour the remaining cheese sauce over the top, followed by an extra sprinkle of cheese, and add crispy bacon bits if desired. This adds an extra layer of flavor, ensuring your Cheesy Chicken Riced Cauliflower Casserole is a crowd-pleaser.

Step 9: Bake Until Golden
Place the assembled casserole in your preheated oven and bake for 25-30 minutes, or until the dish is bubbly and the top is golden brown. If you prefer a crispy finish, switch on the broiler for 2-3 minutes at the end, watching closely to avoid burning.

Step 10: Rest and Serve
After baking, let your Cheesy Chicken Riced Cauliflower Casserole rest for about 10-15 minutes before serving. This resting period allows the dish to set, making it easier to portion. Once plated, consider garnishing with fresh parsley for a pop of color and serve warm, reveling in the deliciousness of your creation!
