Preheat and prep: Heat your oven to 400°F (200°C). Pat the chicken thighs dry with paper towels. Season both sides generously with salt and black pepper.

Sear the chicken: Heat a large oven-safe skillet over medium-high heat. Add olive oil. Place chicken skin-side down and sear without moving for 6–8 minutes, until the skin is deep golden and crisp. Flip and cook 2 minutes on the second side.

Roast to finish: Transfer the skillet to the oven and roast 12–18 minutes, depending on size, until the internal temperature reaches 165°F (74°C). Move the chicken to a plate and tent loosely with foil.

Build the sauce base: Return the skillet to medium heat on the stovetop. Spoon off excess fat, leaving about 1 tablespoon. Add butter and minced garlic. Cook 30–45 seconds, just until fragrant.

Deglaze: Pour in balsamic vinegar and scrape up the browned bits. Stir in honey, chicken broth, Dijon, thyme, and a pinch of red pepper flakes if using.

Reduce and thicken: Simmer 3–5 minutes, stirring, until the sauce is glossy and slightly thickened. It should lightly coat the back of a spoon. Adjust sweetness or tang with a bit more honey or vinegar as needed.

Return the chicken: Add the chicken and any accumulated juices back to the pan. Spoon sauce over the thighs and simmer 1 minute to glaze. For extra brightness, squeeze in a little lemon.

Finish and serve: Sprinkle with chopped parsley. Serve chicken with sauce over rice, mashed potatoes, or roasted vegetables.
