What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a creamy texture. Most of these are pantry staples, but I’ve included a few substitution options where necessary.

Chicken Breast: Cooked and shredded (or use rotisserie chicken for convenience).
Cauliflower Rice: Fresh or frozen, thawed if using frozen.
Butter: Unsalted, for sautéing vegetables and adding richness.
Onion: Diced, for a savory base flavor.
Garlic: Minced, because garlic makes everything better!
Heavy Cream: For the creamy sauce—you can substitute half-and-half or coconut milk for a lighter option.
Chicken Broth: Adds depth and enhances the chicken flavor.
Cream Cheese: Softened, for a velvety texture in the sauce.
Cheddar Cheese: Shredded, for that classic cheesy goodness.
Parmesan Cheese: Freshly grated, for a nutty, salty kick.
Salt and Pepper: To season everything perfectly.
Paprika: Optional, for a hint of smoky flavor.
Fresh Parsley: Chopped, for garnish and a pop of freshness.

Feel free to swap out the cheeses or add a bit of spice with chili flakes for extra heat. You can also use turkey instead of chicken or add veggies like spinach or broccoli for more texture and nutrients.

Equipment Needed

Baking Dish: A 9×13-inch dish works perfectly for this casserole.
Large Skillet: For sautéing vegetables and making the sauce.
Mixing Bowls: To combine ingredients before layering.
Wooden Spoon: Ideal for stirring the sauce without scratching your skillet.
Grater: For shredding cheese—freshly shredded cheese melts better!
Knife and Cutting Board: For prepping chicken and vegetables.

If you don’t have a baking dish, you can use a deep oven-safe skillet. And for shredding chicken quickly, a stand mixer with a paddle attachment works wonders!

Preparation Method

Preheat your oven to 375°F (190°C). Grease your baking dish lightly with cooking spray or a bit of butter.
In a large skillet, melt 2 tablespoons of butter over medium heat. Add the diced onion and sauté for 3-4 minutes until softened. Stir in the minced garlic and cook for another minute until fragrant.
Add the cauliflower rice to the skillet and cook for 5-7 minutes, stirring occasionally, until it’s tender and any excess moisture has evaporated. Remove from heat and set aside.
In a mixing bowl, whisk together the heavy cream, chicken broth, softened cream cheese, and 1 cup of shredded cheddar cheese. Season with salt, pepper, and paprika (if using).
Spread the cooked cauliflower rice evenly in the prepared baking dish. Layer the shredded chicken on top.
Pour the creamy sauce over the chicken and cauliflower rice, ensuring everything is evenly coated.
Top with the remaining cheddar cheese and grated Parmesan cheese.
Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the cheese is golden brown.
Remove from the oven and let it cool for 5 minutes. Sprinkle with chopped fresh parsley before serving.

Tip: If your casserole isn’t browning on top, you can broil it for 2-3 minutes. Just keep an eye on it to avoid burning!

Cooking Tips & Techniques

Ensure your cauliflower rice is well-drained to prevent excess liquid in the casserole.
If your sauce seems too thick, you can thin it with a splash of chicken broth or cream.
Use freshly shredded cheese instead of pre-shredded for better meltability.
If you’re short on time, rotisserie chicken is a lifesaver for this recipe!
Don’t skip resting the casserole after baking—it helps the flavors settle and makes serving easier.

One mistake I made early on was using frozen cauliflower rice without thawing it first. The casserole turned out watery—so now I always make sure to use fresh or properly drained cauliflower rice.

Variations & Adaptations

Keto-Friendly: Swap the cream cheese for a lower-carb alternative and use full-fat cheese.
Vegetarian Option: Skip the chicken and add mushrooms or chickpeas for protein.
Spicy Kick: Stir in diced jalapeños or red chili flakes for some heat.
Seasonal Veggies: Add zucchini or bell peppers in the summer, or butternut squash in the fall.
Dairy-Free: Use coconut cream and dairy-free cheese alternatives.

My personal favorite variation is adding steamed broccoli florets to the casserole—it adds a pop of color and extra nutrition!

Serving & Storage Suggestions

This creamy chicken cauliflower rice casserole bake is best served warm, straight out of the oven. Pair it with a crisp green salad or roasted vegetables for a complete meal. You could also serve it alongside garlic bread for those who don’t mind a few extra carbs.

If you have leftovers, store them in an airtight container in the refrigerator for up to 4 days. To reheat, cover with foil and warm in the oven at 350°F (175°C) for 15 minutes, or microwave individual portions for 2-3 minutes. For longer storage, freeze individual portions for up to 2 months—just make sure to thaw them in the fridge overnight before reheating.

Pro tip: The flavor deepens after a day in the fridge, so don’t be afraid to make this ahead of time!
