In a shallow bowl, combine the sea salt, onion powder, garlic powder, sweet paprika, dried thyme, black pepper, and olive oil.
Add the chicken thighs and toss until each piece is thoroughly coated with the seasoning mixture.
Heat a large, deep, heavy-based pan over medium-high heat. Add the chicken and cook for 6–8 minutes, turning halfway through, until beautifully golden on both sides. Transfer the chicken to a plate. If there is a large amount of rendered fat in the pan, carefully spoon out the excess.
Pour in the water and scrape the bottom of the pan with a wooden spoon to loosen the flavorful browned bits.
Add the diced onion and minced garlic. Cook for 1–2 minutes, stirring frequently, until softened and fragrant.
Add the jasmine rice and chicken stock. Stir gently and bring the mixture to a simmer.
Reduce the heat to low and return the chicken thighs to the pan. If using skin-on thighs, position them skin-side up.
Cover the pan and cook for about 15 minutes, or until the rice is tender and the chicken reaches a safe internal temperature of 165°F (74°C).
Remove the pan from the heat and leave it covered for 10 minutes. This resting time helps the rice finish absorbing the flavorful liquid.
Fluff the rice gently around the chicken. Serve your One Pan Chicken and Garlic Rice with fresh thyme and a mixed leaf salad, if desired.
