• Kosher Salt – Enhances overall flavor; adjust to your taste preference.
• Black Pepper – Adds a subtle kick; fresh ground varieties are recommended for better flavor.
• Garlic (3 cloves, minced) – Provides aromatic sweetness; garlic powder can be a quick substitute.

For the Filling

Step‑by‑Step Instructions for Cheesy Chicken Riced Cauliflower Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 375°F (190°C). While the oven heats, take a moment to lightly grease a 9×13 inch baking dish with avocado oil, ensuring every corner is coated for easy cleanup. This will be the cozy home for your Cheesy Chicken Riced Cauliflower Casserole as it bakes to perfection.
Step 2: Prepare Chicken
If you’re starting with raw chicken, now’s the time to cook it. Use your preferred method—poaching, baking, or pan-searing—until cooked through, about 15–20 minutes depending on the thickness. Once cooled, shred the chicken into bite-sized pieces. This tender chicken will blend beautifully with the creamy casserole base, enhancing every savory bite.
Step 3: Prepare Riced Cauliflower
For the riced cauliflower, if using fresh, take a medium head of cauliflower, trim it, and pulse in a food processor until it resembles rice. Steam or sauté it for about 5–7 minutes until tender, then squeeze out excess moisture using a clean kitchen towel. This crucial step prevents a soggy texture in your Cheesy Chicken Riced Cauliflower Casserole.
Step 4: Chop Aromatics
Next, finely dice one onion and mince three cloves of garlic, ensuring they’re ready to bring an aromatic base to your dish. These ingredients are essential for adding depth and flavor to your casserole, setting the stage for the creamy sauce to follow.
Step 5: Sauté Aromatics
In a large skillet, melt a tablespoon of butter or heat some avocado oil over medium heat. Add the diced onion and cook, stirring occasionally, until they become translucent—this should take about 5 minutes. Then, stir in the minced garlic and cook for an additional minute until fragrant, elevating the flavor profile of your casserole.
Step 6: Build Creamy Base
Lower the heat to medium-low and add four tablespoons of cream cheese to the sautéed onion and garlic, stirring until smooth. Gradually whisk in half a cup of milk and half a cup of plain Greek yogurt until fully combined. This base will create a rich, creamy sauce for your Cheesy Chicken Riced Cauliflower Casserole, adding indulgence to every scoop.
Step 7: Mix Seasonings
Now, it’s time to spice things up! Add half a teaspoon of garlic powder, kosher salt, black pepper to taste, one and a half teaspoons of Italian seasoning, and a tablespoon of Dijon mustard to the creamy base. Stir well to ensure even distribution of flavors, enriching the casserole with amazing savory notes.
Step 8: Add Cheese
Stir in one and a half cups of your choice of cheese blend into the creamy sauce, melting it until the mixture thickens and becomes glossy. The cheese adds that ultimate comforting richness to your Cheesy Chicken Riced Cauliflower Casserole, ensuring a delightfully cheesy experience in every bite.
Step 9: Combine Ingredients
In a large mixing bowl, combine the shredded chicken and the prepared riced cauliflower. If you’re using baby spinach or veggies, toss them into the mix at this stage. Gently fold in the ingredients, making sure the chicken and cauliflower are evenly distributed and ready for the cheesy goodness that awaits.
Step 10: Pour Sauce
Pour the luscious cheese sauce over the chicken and cauliflower mixture, folding gently to ensure everything is well-coated. This creamy sauce is the heart of your Cheesy Chicken Riced Cauliflower Casserole, ensuring each layer is full of flavor and juicy goodness.
Step 11: Transfer to Dish & Top
Carefully spoon the combined mixture into your greased baking dish, spreading it evenly. For an added cheesy crust, sprinkle the remaining cheese on top, allowing for a gooey, irresistible finish. This will create a delightful topping that browns beautifully in the oven.
Step 12: Bake Covered
Cover your dish tightly with aluminum foil to trap steam, ensuring the casserole remains moist as it bakes. Place it in the preheated oven for 25 minutes, allowing the flavors to meld and the chicken to heat through perfectly.
Step 13: Bake Uncovered
After 25 minutes, remove the foil and return the casserole to the oven. Bake for an additional 15-20 minutes until the top is golden-brown and bubbly, creating a tempting crust that invites everyone to the table for your Cheesy Chicken Riced Cauliflower Casserole.
Step 14: Rest & Garnish
Once done, take the casserole out of the oven and let it rest for 10-15 minutes. This resting period allows the flavors to settle and makes serving easier. If desired, garnish with freshly chopped parsley or chives for a pop of color and freshness.
Step 15: Serve & Enjoy
Your Cheesy Chicken Riced Cauliflower Casserole is now ready to serve! Scoop out generous portions and pair it with a side salad or your favorite steamed veggies for a complete meal. This dish promises comfort and satisfaction, perfect for feeding your family or indulging in leftovers the next day.
