Marinate the Chicken
In a bowl, mix yogurt, lemon juice, spices, ginger, and garlic. Add chicken and coat well. Cover and marinate for at least 1 hour (or overnight for deeper flavor).
Sear the Chicken
Preheat oven to 400°F (200°C). In a large ovenproof skillet or Dutch oven, heat oil over medium heat. Add marinated chicken (shake off excess marinade) and sear for 3–4 minutes per side until lightly browned. Remove and set aside.
Sauté the Aromatics
In the same skillet, add more oil if needed. Sauté chopped onion until translucent, about 3–4 minutes. Add garlic, ginger, cumin, and coriander. Cook 1 minute until fragrant.
Add Rice and Liquid
Stir in rinsed rice, coconut milk, water, and a pinch of salt. Bring to a simmer, then nestle the seared chicken thighs on top.
Bake
Cover the pan tightly with a lid or foil. Bake in the preheated oven for 25–30 minutes, or until the rice is tender and the chicken is fully cooked (internal temp 165°F).
Rest and Serve
Let it sit covered for 5 minutes. Garnish with fresh herbs, peas, or toasted cashews if desired. Serve warm.
