Creating Oven Baked Chicken and Rice is simple if you follow these concise steps:

1. Preheat your oven to 375°F (190°C).
2. Season the Chicken: In a bowl, rub the chicken thighs with olive oil, paprika, oregano, salt, and pepper. Ensure they’re well coated.
3. Sauté Onions and Garlic: In an oven-safe pan, over medium heat, sauté the diced onion and minced garlic until the onion becomes translucent, approximately 3-5 minutes.
4. Add Rice: Stir in the rice until it is well mixed with the onion and garlic.
5. Incorporate Broth: Pour in the chicken broth and bring the mixture to a gentle simmer.
6. Arrange the Chicken: Place the seasoned chicken thighs, skin-side up, on top of the rice mixture.
7. Add Vegetables (Optional): Sprinkle in any mixed vegetables you desire around the chicken.
8. Cover and Bake: Cover the pan with aluminum foil or a lid and bake in the preheated oven for 30 minutes.
9. Uncover and Continue Baking: After 30 minutes, remove the cover. Bake for an additional 15-20 minutes, or until the chicken is cooked through and the rice is tender. An internal temperature of 165°F (75°C) should be reached.
10. Rest and Serve: Let it sit for a few minutes before serving. This allows the flavors to meld and the rice to absorb any remaining broth.

Following these steps will lead you to a beautifully baked dish that’s not only nutritious but also bursting with flavor.
