Step-by-Step Instructions

Step 1: Prepare the cauliflower rice

In a large skillet, heat olive oil over medium heat. Add chopped onion and sauté until soft and translucent, then stir in garlic and cook for another 30 seconds. Add cauliflower rice and cook for 5–6 minutes until just tender.

Step 2: Mix the casserole base

In a large bowl, combine shredded chicken, cooked cauliflower rice mixture, sour cream (or Greek yogurt), half of the mozzarella cheese, Parmesan cheese, paprika, thyme, salt, and pepper. Stir well until evenly mixed.

Step 4: Bake until golden

Bake for 25–30 minutes until the cheese is melted, bubbly, and lightly golden on top. Remove from oven and let it rest for 5 minutes before serving. Garnish with fresh parsley.
