Preheat your oven to 375°F (190°C).
In a large, oven-safe skillet, heat olive oil over medium heat.
Season the chicken thighs with salt, pepper, paprika, and oregano.
Add the seasoned chicken, skin-side down, to the skillet.
Sear the chicken for 5-7 minutes until it's browned.
Flip the chicken and add onions and bell peppers.
Stir in the minced garlic and cook for an additional minute.
Pour in the rice and stir to combine all ingredients.
Add the chicken broth and lemon juice, bringing it to a simmer.
Nestle the chicken pieces on top of the rice mixture.
Cover the skillet with a lid or foil and bake for 30-35 minutes.
Remove from oven, stir in frozen peas, and let it rest.
Serve hot, garnished with fresh herbs if desired.
