Preheat and prep: Heat the oven to 400°F (200°C).
Pat the chicken dry with paper towels. Halve the baby potatoes. Zest and juice the lemon.
Season the chicken: Sprinkle both sides of the chicken with salt, pepper, and half the chopped herbs.
Dry skin and a good dose of salt help you get crisp, golden skin.
Sear the chicken: In a large oven-safe skillet or Dutch oven, heat 1–2 tablespoons olive oil over medium-high. Place the chicken skin-side down and sear until deeply golden, about 5–7 minutes. Flip and cook 2–3 minutes more.
Transfer to a plate.
Sauté aromatics: Lower heat to medium. Add another drizzle of oil if needed. Stir in the garlic and the remaining herbs.
Cook 30–60 seconds until fragrant—don’t let the garlic burn.
Add potatoes: Toss in the potatoes with a big pinch of salt and pepper. Stir to coat in the garlicky oil and herbs. Let them get a little color for 2–3 minutes, stirring once or twice.
Deglaze: Pour in the chicken broth (or wine).
Scrape up the browned bits from the bottom of the pan. Add the lemon zest and half the lemon juice. Taste the liquid and adjust salt and acidity.
It should be bright but rounded.
Nestle and roast: Return the chicken to the pot, skin-side up. Tuck in a few thin lemon slices if you like. Transfer to the oven and roast 20–25 minutes, until the chicken reaches an internal temperature of 165°F (74°C) and the potatoes are tender.
Optional finish: Stir in 1 tablespoon butter to the pan juices for a silkier sauce.
Squeeze in a bit more lemon juice if you want extra brightness. Taste and adjust seasoning.
Garnish and serve: Scatter chopped parsley over everything. Spoon the lemony pan sauce over the chicken and potatoes.
Serve straight from the pot.
