First, I preheat my oven to 350°F (about 175°C). In a mixing bowl, I whisk together the dried oregano, sweet paprika, coriander, salt, and black pepper. Then I pat my chicken thighs dry and toss them in the spice mix, finishing by squeezing in juice from half a lemon. Next, I heat some extra virgin olive oil in my Dutch oven over medium-high heat. When it's shimmering, I sear the chicken for about 8–10 minutes, turning so both sides develop a golden crust — it doesn’t need to be fully cooked yet. Once browned, I move the chicken to a plate and set aside.
Using the same pot, I add the bell pepper slices and sear them lightly so they pick up some char and flavor. When they’ve softened a bit and gained color, I transfer them to join the chicken on the plate.
If the pot feels a little dry now, I drizzle in another tablespoon of olive oil. Then I add the chopped onion, stirring and cooking for about 5 minutes until it’s soft and translucent. I toss in the garlic and let it cook just 30 more seconds, until fragrant. After that, I pour in the canned plum tomatoes (with their juice), chicken broth, another teaspoon of oregano, another teaspoon of paprika, and a pinch of salt and pepper. I bring this mixture to a gentle boil, then stir in the uncooked orzo.
Now it’s time to nestle the browned chicken pieces back into the orzo mixture, and layer the seared bell pepper rounds on top. I transfer the whole pot (uncovered) into the preheated oven. It bakes around 20–25 minutes, or until the orzo has absorbed most of the liquid and is tender.
When oven time is up, I remove the pot and put the lid on. I let it rest undisturbed for 5 minutes so the orzo can absorb any remaining juices. Then I drizzle a little extra virgin olive oil over the top, and finish things with a sprinkle of freshly chopped parsley and plenty of crumbled feta, if I’m using it.
