Pat dry and season: Blot chicken thighs with paper towels. Season both sides with 1 to 1.5 teaspoons salt and 1/2 teaspoon black pepper.
This step helps crisp the skin and deepen flavor.
Make the glaze: In a bowl or measuring cup, whisk together balsamic vinegar, honey, soy sauce, Dijon, and minced garlic. Add a pinch of red pepper flakes if you like heat.
Sear the chicken: Heat olive oil in a large oven-safe skillet over medium-high heat. Place thighs skin-side down and cook 6–8 minutes, until the skin is deep golden and crisp.
Don’t move them too much; let the heat do the work. Flip and cook the other side for 2–3 minutes.
Add glaze and herbs: Pour the balsamic mixture around the chicken (not directly on the crisp skin just yet). Tuck in thyme or rosemary sprigs if using.
Reduce heat to medium and simmer 2–3 minutes to start thickening.
Finish in the oven: Transfer the skillet to a 400°F (200°C) oven. Roast 12–15 minutes, until the chicken reaches 175°F–185°F in the thickest part. Thighs like higher temps; they get more tender.
Glaze to glossy: Return the skillet to the stovetop over medium heat.
Remove the herbs. Spoon the sauce over the chicken, letting it bubble and reduce for 2–4 minutes until it’s syrupy and coats the back of a spoon. Stir in butter for extra sheen, if you like.
Rest and finish: Let the chicken rest 5 minutes.
Spoon glaze over the skin again. Scatter chopped parsley and add a light squeeze of lemon for brightness.
Serve: Plate with sides that soak up sauce—mashed potatoes, creamy polenta, rice, or roasted carrots and green beans.
