Heat olive oil in a large skillet over medium-high heat.
Season the chicken thighs with salt, pepper, and smoked paprika, then add to the skillet, skin side down.
Cook the chicken for about 5-7 minutes until golden brown, then flip and cook for another 5 minutes.
Remove the chicken from the pan and set aside. Add onion and red bell pepper to the skillet.
Sauté for about 3-4 minutes until the vegetables are soft, then add garlic and oregano.
Stir in the rice, making sure to coat it in the mixture, then add chicken broth and lemon juice.
Return the chicken thighs to the skillet, nestling them into the rice mixture.
Bring the mixture to a boil, then reduce heat to low, cover, and let simmer for about 20-25 minutes.
After cooking, remove the skillet from heat and let it sit for 5 minutes before serving.
Garnish with fresh parsley before serving.
