Marinate Chicken: Combine the chicken thighs with half the olive oil, smoked paprika, ground cumin, ground coriander, and salt. Mix well and set aside.
Sear Chicken: Heat the remaining olive oil in the pressure cooker pot over high heat. Sear the marinated chicken thighs on both sides until golden brown. Remove and set aside.
Sauté Vegetables: In the same pot, sauté the diced onion, sliced chillies, and garlic for 2-3 minutes until the onion softens.
Add Rice and Stock: Add the rice, stirring briefly to coat. Pour in the chicken stock and add the green beans. Bring to a simmer.
Cook Under Pressure: Place the chicken thighs back on top of the rice, along with any collected juices. Secure the lid and set the cooker to high pressure. Cook for 6 minutes.
Finish and Serve: Release the pressure and open the lid. Remove the chicken, fluff the rice, and serve with chicken on top, garnished with fresh parsley.
