Rub the chicken thighs with garlic powder, smoked paprika, and onion powder on both sides.
Heat olive oil in a large skillet over medium-high heat and sear the chicken skin-side down for 5 minutes until golden, then flip and sear for 3 minutes.
Remove the chicken, add the rice to the skillet, stir for 1 minute, then pour in the chicken broth and bring to a boil.
Place the chicken thighs on top of the rice, reduce heat to low, cover, and simmer for 20 minutes until the rice is tender and the chicken reaches 165°F / 74°C at the thickest part.
Stir in the frozen peas, cover, and let rest for 5 minutes off the heat before serving.
