Creating the Healthy Zucchini Parmesan Rice Casserole is quite straightforward if you follow these steps:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C). Prepare a baking dish by spraying it lightly with cooking spray.

2. Cook the Rice: In a pot, combine the uncooked brown rice and 2 cups of vegetable broth. Bring to a boil, cover, and simmer for about 40-45 minutes, or until the rice is tender and the liquid is absorbed.

3. Sauté the Vegetables: In a skillet over medium heat, add a splash of olive oil. Sauté the diced onions and minced garlic until they’re fragrant and softened, about 3-4 minutes.

4. Grate the Zucchini: While the onions are cooking, grate the zucchinis using a box grater and place them in a clean kitchen towel. Squeeze out excess moisture, ensuring they don’t make the casserole watery.

5. Combine Ingredients: In a large mixing bowl, combine the cooked rice, sautéed onions, grated zucchini, dried oregano, dried basil, salt, black pepper, Greek yogurt, and half of the Parmesan cheese. Mix until everything is evenly combined.

6. Transfer to Baking Dish: Spoon the mixture into the prepared baking dish, spreading it out evenly. Top with the remaining Parmesan cheese for a delicious, cheesy crust.

7. Bake: Place the baking dish in the preheated oven. Bake for 30-35 minutes, or until the top is golden and bubbly.

8. Cool Slightly: Once baked, take the casserole out of the oven and let it cool for 5-10 minutes before serving. This helps it set and makes for easier slicing.

9. Garnish: Sprinkle with chopped fresh parsley for a colorful and flavorful garnish before serving.

Following these steps will help you create a delicious and healthy casserole that your family will love!
