How to Make Mouthwatering Cheesy Chicken Riced Cauliflower Casserole
- Preheat: Set your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish to prepare for this delicious dish!
- Season: Pat the chicken dry and sprinkle it generously with a mix of garlic powder, Italian herbs, salt, and pepper to infuse flavor.
- Sear: Heat a tablespoon of oil in a skillet over medium-high heat. Cook the chicken for about 4-5 minutes on each side until golden and sizzling.
- Bake: Move the seared chicken to an oven-safe dish and bake for 15-20 minutes, or until it reaches 165°F (74°C) inside.
- Rest: Remove the chicken, cover it loosely with foil, and let it relax for 5-10 minutes before shredding—this keeps the meat juicy.
- Rice: Trim and pulse cauliflower florets in a food processor until they look like rice—this will create a healthy base for the casserole.
- Sauté: In the skillet, heat another tablespoon of oil and cook the riced cauliflower for 7-10 minutes, allowing it to soften and most moisture to evaporate.
- Make Roux: In a large saucepan, melt butter over medium heat and whisk in flour to form a smooth, pale roux, cooking until it bubbles gently.
- Whisk: Gradually add warmed milk and chicken broth to the roux, whisking continuously until the mixture thickens into a creamy sauce, about 3-5 minutes.
- Incorporate: Lower the heat and mix in cream cheese, Dijon mustard, and seasonings—whisk until it’s creamy and smooth.
- Add Cheese: Stir in shredded cheddar, Monterey Jack, and Parmesan until fully melted and incorporated into the sauce.
- Combine: In a large bowl, mix the shredded chicken and sautéed cauliflower. Pour in about two-thirds of the cheese sauce and combine gently.
- Transfer: Spoon the mixture into the greased baking dish and spread it out evenly, creating a flat surface for the toppings.
- Layer: Drizzle the remaining cheese sauce on top and sprinkle with any extra shredded cheese. Optional: add crumbled bacon for extra flavor.
- Bake: Place the dish in the oven for 25-30 minutes, until bubbly and the cheese is melted and golden brown.
- Broil: For an extra crispy topping, broil for the last 2-3 minutes—just keep an eye out to avoid burning!
- Rest: Let the casserole sit for 10-15 minutes after removing it from the oven to allow the flavors to settle.
- Garnish: Top with fresh herbs, like parsley or chives, for a pop of color and flavor before serving. Enjoy warm!
💡 Pro Tip: Cool the chicken a bit before shredding; it makes for easier handling and keeps it tender!
