Preheat your oven to 400°F (200°C).
Season the chicken thighs generously with salt and black pepper on both sides.
Melt 2 tablespoons of butter in a large, oven-proof skillet over medium-high heat. Place the chicken thighs skin-side down and sear for 2-3 minutes per side, until golden brown. Transfer the chicken to a plate.
Add the remaining tablespoon of butter to the skillet, stirring to scrape up any browned bits. Toss in the minced garlic and cook for about 30 seconds, until fragrant.
Stir in the brown sugar, honey, oregano, thyme, and basil, letting the mixture combine fully and thicken slightly. Turn off the heat.
Return the seared chicken thighs to the skillet, placing them skin-side down in the glaze.
Slide the skillet into the oven and roast for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Once done, drizzle the pan sauce over the chicken thighs before serving for extra flavor.
