Introduction
This Healthy Chicken Cauliflower Rice Casserole is a comforting dish that feels indulgent without weighing you down. Packed with fresh vegetables, tender chicken, and melty cheese, it’s perfect for a cozy weeknight dinner that’s both nutritious and delicious.

Ingredients
- 1 lb cooked chicken breast (shredded or diced)
- 4 cups cauliflower rice (fresh or frozen and thawed)
- 1 small onion, diced
- 2 cloves garlic, minced
- 1 cup broccoli florets (small pieces work best)
- 1/2 cup shredded carrots
- 1/2 cup plain Greek yogurt or sour cream
- 1/2 cup shredded mozzarella
- 1/2 cup shredded cheddar
- 1/4 cup grated Parmesan
- 1/2 tsp dried thyme
- 1/2 tsp smoked paprika
- Salt and pepper to taste
- Olive oil for sautéing
- Optional: a squeeze of lemon juice or fresh parsley for garnish
Instructions
- Step 1: Preheat your oven to 375°F (190°C). Grease a 9×13-inch casserole dish and set it aside.
- Step 2: In a large skillet, heat a drizzle of olive oil over medium heat. Add the diced onion and sauté for 3–4 minutes until soft. Stir in the minced garlic, broccoli florets, and shredded carrots. Cook for another 5–6 minutes until the vegetables are slightly tender, then remove from heat.
- Step 3: In a large mixing bowl, combine the cauliflower rice, cooked chicken, sautéed vegetables, Greek yogurt or sour cream, mozzarella, cheddar, Parmesan, dried thyme, smoked paprika, salt, and pepper. Stir until everything is evenly mixed. If the mixture feels too dry, add a splash of milk or broth to loosen it.
- Step 4: Transfer the mixture into the prepared casserole dish and spread it out evenly. If you like, sprinkle a little extra cheese on top. Bake uncovered for 25–30 minutes until the casserole is hot, bubbly, and lightly golden on top.
- Step 5: Let the casserole cool for a few minutes before serving. Garnish with fresh parsley or a squeeze of lemon juice for a bright finish, if desired.
