Creating Healthier Broccoli Chicken Casserole is straightforward with these easy steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook the Rice/Quinoa: Prepare the brown rice or quinoa according to package instructions. Set aside.
3. Steam the Broccoli: In a pot, steam the broccoli florets until bright green and slightly tender, about 3-5 minutes. Drain and set aside.
4. Sauté Garlic: In a skillet, heat olive oil over medium heat. Add minced garlic, sautéing for about 1 minute until fragrant.
5. Mix the Casserole Ingredients: In a large mixing bowl, combine shredded chicken, cooked rice/quinoa, steamed broccoli, Greek yogurt, chicken broth, paprika, onion powder, salt, and pepper. Mix until well combined.
6. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly.
7. Add Cheese: Sprinkle the shredded cheese evenly over the top of the casserole. If desired, add breadcrumbs for an extra crispy topping.
8. Bake: Place the baking dish in the oven and bake for 25-30 minutes, or until the cheese is melted and bubbly.
9. Cool and Serve: Allow the casserole to cool for a few minutes before serving.
