Step‑by‑Step Instructions for Cheesy Chicken and Cauliflower Rice Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While that heats up, grab a 9×13-inch casserole dish and give it a generous coat of avocado oil to prevent sticking. This step ensures that your Cheesy Chicken and Cauliflower Rice Casserole bakes evenly and comes out perfectly golden.

Step 2: Sauté the Onions
In a Dutch oven, heat 2 tablespoons of avocado oil over medium-high heat. Once the oil shimmers, add one diced onion and sauté for about 5-7 minutes until it softens and turns translucent. Keep an eye on it to avoid burning, as this fragrant base enhances the flavor of your casserole.

Step 3: Cook the Cauliflower
Next, stir in 4 cups of frozen riced cauliflower into the onions, seasoning with kosher salt and black pepper. Cook this mixture for about 8-10 minutes, stirring occasionally, until the cauliflower becomes tender and begins to brown slightly. This step adds delicious texture and a veggie boost to your Cheesy Chicken and Cauliflower Rice Casserole.

Step 4: Add Garlic
Lower the heat and mix in 3-4 cloves of minced garlic. Sauté for an additional 1-2 minutes until the garlic is fragrant but not browned. The aroma will fill your kitchen, setting the stage for a comforting casserole that your family will anticipate.

Step 5: Create the Sauce
Now, lower the heat and pour in 1 cup of milk along with 1 teaspoon of garlic powder, 1 tablespoon of Italian seasoning, and 1 tablespoon of Dijon mustard. Add 8 ounces of cream cheese and ½ cup of plain Greek yogurt into the pot. Stir until the mixture is smooth and creamy, ensuring all ingredients are well combined and the flavors meld beautifully.

Step 6: Mix in Greens and Proteins
Add 3 cups of fresh baby spinach, 2 cups of cooked shredded chicken, and 2 cups of cooked white jasmine rice to the mixture. Gently fold everything together, allowing the spinach to wilt and incorporate while ensuring the chicken and rice are evenly dispersed throughout. This hearty blend will be the heart of your Cheesy Chicken and Cauliflower Rice Casserole.

Step 7: Assemble the Casserole
Pour the entire mixture into the greased casserole dish, spreading it evenly. Top it off with 1-2 cups of shredded cheddar cheese, allowing for a gooey, melty finish. This is where your casserole starts to take shape, ready for the oven!

Step 8: Bake the Casserole
Cover the dish with aluminum foil and place it in the preheated oven for 25 minutes. This step ensures that the casserole heats through and flavors meld together perfectly. After 25 minutes, remove the foil and switch the oven to broil.

Step 9: Broil for a Crispy Finish
Broil the dish for an additional 2-3 minutes until the cheese is bubbly and golden brown. Keep a close eye to prevent burning, as broilers can vary in strength. Look for a beautifully bubbly, crispy top that will invite everyone to the table for this delightful Cheesy Chicken and Cauliflower Rice Casserole!

Make Ahead Options

These Cheesy Chicken, Rice & Cauliflower Rice Casserole preparations are perfect for busy weeknights! You can assemble the entire casserole up to 24 hours in advance; simply prepare the mixture, transfer it to the greased dish, and cover tightly with foil before refrigerating.

When you’re ready to serve, just pop it in the oven (no need to thaw), follow with the 25 minutes of baking, then uncover and broil for that irresistible crispy cheese top. Enjoy restaurant-quality ease and comfort at home!

Cheesy Chicken and Cauliflower Rice Casserole Recipe FAQs

How do I choose the best riced cauliflower for my casserole?
Absolutely! When selecting riced cauliflower, look for packages that are free from dark spots or excess moisture as this can indicate spoilage. If you’re using fresh riced cauliflower, ensure it’s firm and not wilted. Trust me, fresh ones roast beautifully, adding a lovely texture to your dish!

What’s the best way to store leftovers of the casserole?
Very! Once the casserole has cooled to room temperature, transfer it to an airtight container and store it in the fridge. It will keep well for up to 4 days. Just remember to let it cool completely before sealing to prevent condensation inside the container.

Can I freeze Cheesy Chicken and Cauliflower Rice Casserole? How?
Of course! To freeze, let the casserole cool fully, then wrap it tightly in plastic wrap followed by aluminum foil. This layering prevents freezer burn. Place it in a freezer-safe container for up to 3 months. When you’re ready to enjoy, thaw it overnight in the fridge before reheating, so it warms evenly.

What should I do if my casserole turns out too dry?
No worries! If you find your casserole is a bit dry, next time ensure you’re mixing enough sauce ingredients, specifically the cream cheese and milk, to create a creamy consistency. You can also add a splash of chicken broth when reheating if it seems a little parched—this can revive the flavors beautifully.

Are there any allergens I should be aware of in this dish?
Good question! This casserole is nut-free and gluten-free, making it suitable for many diets. However, if you or someone in your family has a dairy allergy, consider substituting the cream cheese and shredded cheddar cheese with dairy-free alternatives that are available in stores. Always read labels to avoid hidden allergens.
