Heat 1 tbsp olive oil in a frying pan over medium-high heat.
When the pan is hot, place both chicken breasts in the pan and sear for 1 minute.
Add the butter, garlic clove, and thyme sprigs to the pan. Baste the chicken with the melted butter for 1 minute.
Transfer the pan to the preheated oven and cook for 12 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
