Preheat the oven to 375°F (190°C).
Season the chicken thighs with salt and pepper.
Heat the olive oil in a large Dutch oven over medium-high heat. Add the chicken thighs skin side down and cook until the skin is crispy and golden brown, about 5 minutes. Flip the chicken over and cook for an additional 2-3 minutes.
Remove the chicken from the pot and set it aside on a plate.
Add the onion, garlic, and bell peppers to the pot and cook until they are softened, about 3-4 minutes.
Add the rice to the pot and stir to coat it in the oil and vegetable mixture. Cook for 1-2 minutes, until the rice is lightly toasted.
Add the chicken broth, paprika, oregano, thyme, and a pinch of salt and pepper. Stir to combine everything together.
Place the chicken thighs back in the pot on top of the rice mixture, skin side up.
Cover the Dutch oven with a lid and transfer it to the preheated oven.
Bake for 35-40 minutes, until the chicken is cooked through and the rice is tender and fluffy.
Remove the pot from the oven and let it rest for 5 minutes.
Fluff the rice with a fork and garnish the dish with lemon wedges and chopped parsley.
