Preheat the oven to 425°F.
Pat the chicken dry with paper towels and place the pieces skin-side up in a large ovenproof skillet or baking dish, leaving a little space between each piece.
In a small bowl, whisk together the melted butter and honey until smooth.
Whisk in the herbes de Provence, salt, and a generous amount of freshly ground black pepper until evenly combined.
Pour the honey mixture over the chicken, turning or brushing the pieces so they get evenly coated. Return them to skin-side up.
Pour the wine around the chicken in the pan.
Bake for 35-45 minutes, until the skin is deeply golden and an instant‑read thermometer inserted into the thickest part of a breast (without touching bone) registers 165°F. If the skin begins to char before the chicken is cooked through, loosely tent the pan with foil for the last 5-10 minutes.
Transfer the cooked chicken to a plate, tent loosely with foil to keep warm, and let rest for 10 minutes.
Place the skillet with the pan juices over medium‑high heat and bring to a boil. Simmer for about 3 minutes to reduce slightly.
In a small bowl, whisk the flour and chicken stock together to make a smooth slurry. Whisk the slurry into the boiling pan juices and cook, whisking constantly, until the sauce bubbles and thickens, 2-3 minutes. Taste and adjust seasoning with additional salt and pepper as needed.
Spoon the sauce over the chicken and serve warm.
