Season the chicken with ½ teaspoon of salt, ¼ teaspoon of black pepper, and ½ teaspoon of garlic powder.
Heat oil over medium heat and cook chicken until done, about 4-5 minutes on each side, then set aside.
Melt butter and cook garlic until fragrant. Add white wine, reduce by half over medium-high heat for 3-5 minutes, scraping the bottom of the pot to release brown bits.
Stir in rice to coat, spread evenly in skillet. Add broth, parmesan rind, thyme, and nestle chicken on top.
Bring to a boil over medium-high heat, then reduce to medium-low, cover, and simmer for 20 minutes or until the rice is cooked through. Do not stir!
Turn off the heat, sprinkle grated parmesan cheese over the rice, cover, and let it rest for 10 minutes before serving.
Fluff the rice, season with additional salt if desired, and serve with the chicken pieces and green onion.
