Preheat oven to 375°F.
Pat chicken breasts dry and place on a plate or cutting board.
In a small bowl, mix salt, pepper, onion powder, and basil. Sprinkle evenly on both sides of the chicken to coat.
Heat oil in a Dutch oven over medium-high heat. Sear chicken for 1–2 minutes per side, working in batches if needed. Transfer seared chicken to a clean plate.
Add garlic to the pot and sauté briefly, about 30 seconds.
Pour in the wine, scraping up browned bits from the bottom to deglaze the pan.
Return chicken to the pot. Add broth, lemon juice, and rice. Stir gently to combine.
Cover and bake for 20–25 minutes, until chicken reaches an internal temperature of 165°F and rice is tender.
Let rest 5–10 minutes with the lid off before serving. The sauce will continue to thicken as it sits.
