Preheat your oven to 375°F (190°C).
Season the chicken thighs with salt, pepper, and oregano.
In a large oven-safe skillet, heat olive oil over medium-high heat. Brown the chicken on both sides, about 5 minutes per side. Remove and set aside.
Add minced garlic to the skillet and cook until fragrant, about 30 seconds.
Stir in the rice, lemon juice, and chicken broth. Bring to a simmer.
Return the chicken to the skillet on top of the rice.
Cover with foil and bake for 35-40 minutes, until the rice is tender and the chicken is cooked through.
Garnish with fresh parsley before serving.
