Preheat oven to 400 degrees F. Preheat large dutch oven on medium-high heat and swirl oil to coat.
Add raw chicken, garlic powder, oregano, salt, pepper and cook for 5 minutes, stirring occasionally.
Add rice and broth, stir and bring to a boil. Lay broccoli on top and do not stir, cover and bake in the oven for 40 minutes. You can also add broccoli after baking for a crunchy broccoli.
Remove from the oven, add yogurt and green onion, stir. Sprinkle cheese on top, cover and let stand for 5 minutes until cheese has melted. Serve hot.
Notes
Store: Refrigerate in an airtight container for up to 3 days.
Freeze: Fully cook, cool completely and freeze in an airtight container for up to 3 months. Thaw in a fridge overnight. Reheat in a microwave or in the oven at 375 F for 10 minutes.
Type of brown rice: Brown jasmine or basmati rice grains stay separated once cooked. Long grain brown rice is just as good taste wise. Short grain rice will yield in more mushy casserole but still delicious.
Dutch oven: Cooks food evenly and I highly recommend to use it to make this recipe.
