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

  1. Step 1: Preheat your oven to 375°F (190°C). Grease a 9×13-inch casserole dish and set it aside.
  2. 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. Remove from heat.
  3. 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 seems dry, add a splash of milk or broth.
  4. Step 4: Transfer the mixture to your prepared casserole dish and spread it out evenly. If desired, sprinkle extra cheese on top. Bake uncovered for 25–30 minutes until hot, bubbly, and golden on top.
  5. Step 5: Let the casserole cool for a few minutes before serving. Garnish with fresh parsley or a squeeze of lemon juice to brighten the flavors.

Tips & Variations

  • Use fresh cauliflower rice for a firmer texture or frozen for convenience—just be sure to thaw and drain any excess moisture to avoid a soggy casserole.
  • Swap out the chicken for cooked turkey or tofu for a protein variation.
  • Add a pinch of crushed red pepper flakes for a little heat.
  • For creamier texture, mix in a little cream cheese or more Greek yogurt before baking.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through. This casserole can also be frozen for up to 2 months; thaw overnight in the fridge before reheating.

How to Serve

A slice of creamy baked casserole sits on a white plate with a thin brown rim, placed on a white marbled surface. The dish has three visible layers: the bottom layer is soft white rice, the middle layer is tender shredded chicken, and the top layer is a golden, melted cheese crust with a slightly crispy texture. Small green parsley leaves are scattered on top of the cheese and around the plate for garnish. The lighting highlights the creamy texture and the rich, warm colors of the cheese topping, capturing a cozy and inviting feel. photo taken with an iphone --ar 4:5 --v 7
