Why This Chicken Cauliflower Rice Casserole Works

Traditional casseroles often rely on pasta, rice, or potatoes as a base. While delicious, those ingredients can significantly increase carbohydrate content. Cauliflower rice offers a lighter alternative that absorbs flavor beautifully while keeping the dish lower in carbs and calories.

Pairing cauliflower rice with shredded chicken creates a protein-rich base that keeps you full longer. The cream cheese and shredded cheddar provide creaminess and richness without overwhelming the dish, especially when balanced with garlic powder, onion powder, paprika, salt, and pepper.

This casserole is:

• High in protein
• Lower in carbohydrates
• Family-friendly
• Meal-prep friendly
• Customizable with optional vegetables

Ingredients

This recipe serves 6 people.

Main Ingredients

• 3 cups shredded chicken (rotisserie or cooked chicken breast)
• 4 cups cauliflower rice (store-bought or homemade)
• 8 oz (1 cup) cream cheese, softened
  or Greek yogurt for a lighter version
• 1 cup shredded cheddar cheese, divided
  (or a mix of cheeses like mozzarella and Parmesan)
• 1 tsp garlic powder
• 1 tsp onion powder
• ½ tsp paprika
• ½ tsp salt, adjust to taste
• ½ tsp black pepper
• 1 tbsp olive oil, for sautéing the cauliflower rice

Optional Add-Ins (Same Recipe, Extra Nutrition)

• 1 cup chopped spinach
• 1 cup broccoli florets
• 1 cup sliced mushrooms

Equipment Needed

• Large skillet
• Large mixing bowl
• 9×13-inch baking dish
• Wooden spoon or spatula
• Measuring cups and spoons
• Oven

Preparation Method (Step-by-Step)

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish and set it aside.

If you are using raw chicken breast, cook it first by baking, boiling, or pan-searing until fully cooked, then shred it using two forks. Rotisserie chicken works especially well for saving time and adding flavor.

If making cauliflower rice at home, pulse fresh cauliflower florets in a food processor until they resemble rice-sized pieces.

Step 2: Sauté the Cauliflower Rice

Heat 1 tablespoon olive oil in a large skillet over medium heat.
Add the cauliflower rice and sauté for 5–7 minutes, stirring occasionally.

The goal here is to:

• Soften the cauliflower
• Allow excess moisture to evaporate
• Prevent a watery casserole

Once the cauliflower rice is tender and relatively dry, remove it from the heat.

Step 3: Mix the Ingredients

In a large mixing bowl, combine:

• Shredded chicken
• Sautéed cauliflower rice
• Softened cream cheese (or Greek yogurt)
• ½ cup shredded cheddar cheese
• Garlic powder
• Onion powder
• Paprika
• Salt
• Black pepper

Stir until everything is evenly combined and coated in the creamy mixture.

If you’re using optional vegetables like spinach, broccoli, or mushrooms, lightly sauté them first to remove excess moisture before adding them to the bowl.

Step 4: Assemble the Casserole

Transfer the mixture into the prepared baking dish.
Spread it evenly to ensure consistent baking.

Sprinkle the remaining ½ cup shredded cheddar cheese over the top. This layer creates a golden, melty crust that adds texture and flavor.

Step 5: Bake

Place the casserole in the preheated oven and bake uncovered for 20–25 minutes, or until:

• The cheese is fully melted
• The top is lightly golden
• The casserole is heated through

Once baked, remove from the oven and let it rest for 5 minutes before serving.

Cooking Tips for Best Results

• Always sauté cauliflower rice to avoid excess liquid.
• Use softened cream cheese so it mixes smoothly.
• Avoid overbaking, which can dry out the chicken.
• Let the casserole rest briefly before serving so it sets properly.
• Season gradually and taste before baking when possible.
