Preheat the oven to 425°F. Place the garlic, thyme, rosemary, and chicken broth in the bottom of a roasting pan fitted with a wire rack. Alternatively, place a wire rack over a 15 x 10-inch rimmed sheet pan and add the broth and aromatics beneath the rack.
Pat the chicken dry and season with salt and black pepper. Sprinkle the skin side with half the herbes de Provence.
Heat 2 tablespoons of olive oil in a large nonstick skillet or sauté pan over medium-high heat.
Place the chicken skin-side down and sear for 3–4 minutes, or until golden brown. Season the underside (now facing you) with the remaining herbes de Provence.
Turn the chicken skin-side up and transfer it to the prepared roasting pan or sheet pan.
Carefully add the wine to the skillet. Bring to a simmer, scraping up any browned bits, then pour the wine and pan drippings into the roasting pan beneath the chicken.
Roast for 15 minutes in the center of the oven. Meanwhile, prepare the potatoes.
Roast for 15 minutes. Meanwhile, prepare the potatoes.
Reduce the oven temperature to 375°F. Add the potatoes to the oven and continue roasting the chicken for 35–45 minutes, or until the breast registers at least 165°F and the thickest part of the thigh registers 170–175°F, without touching the bone.
Transfer the chicken to a cutting board and let it rest for 5–10 minutes before carving.
Strain the pan juices into a small bowl or gravy separator. Skim off the excess fat if desired and serve with the chicken.
