Ingredients
  

  • Cooked chicken: 3 cups, shredded or diced (rotisserie works well)
  • Cooked brown rice: 3 cups (or white rice if preferred)
  • Broccoli: 4 cups small florets (fresh or frozen)
  • Onion: 1 small, finely chopped
  • Garlic: 3 cloves, minced
  • Low-sodium chicken broth: 1 cup
  • Plain Greek yogurt (2% or 0%): 1 cup
  • Olive oil: 1–2 tablespoons
  • Shredded cheese: 1–1½ cups (sharp cheddar, part-skim mozzarella, or a mix)
  • Whole-wheat panko or breadcrumbs (optional): 1/2 cup
  • Dijon mustard: 2 teaspoons
  • Onion powder: 1 teaspoon
  • Smoked paprika (optional): 1/2 teaspoon
  • Salt and black pepper: to taste
  • Lemon zest: from 1/2 lemon (optional, for brightness)
  • Fresh parsley: a small handful, chopped (optional garnish)

Method
 

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
  2. Prep the broccoli. If using fresh, cut into small, bite-size florets. Blanch in boiling water for 2 minutes, then drain well. If using frozen, thaw and squeeze out extra moisture.
  3. Warm a large skillet over medium heat. Add olive oil, then sauté the chopped onion for 3–4 minutes until translucent. Stir in garlic and cook 30 seconds, just until fragrant.
  4. Make the light creamy base. Lower heat and pour in the chicken broth. Whisk in Greek yogurt, Dijon, onion powder, smoked paprika, salt, and pepper. Heat gently, stirring, until smooth and steamy. Do not boil.
  5. Add lemon zest if using, then taste and adjust seasoning. The sauce should be savory with a little tang from the yogurt and mustard.
  6. In a large bowl, combine cooked rice, chicken, and broccoli. Pour the sauce over and stir until everything is evenly coated.
  7. Transfer the mixture to the prepared baking dish. Sprinkle shredded cheese evenly over the top. If using, add a light layer of whole-wheat panko for crunch.
  8. Bake uncovered for 20–25 minutes, until the casserole is hot and the cheese is melted and bubbling around the edges.
  9. Rest for 5–10 minutes before serving. Garnish with chopped parsley for a fresh finish.
