This elegant roast chicken dinner pairs crisp golden skin with buttery Jersey Royals and a savory watercress stuffing. It is a beautiful centerpiece for Sunday lunch or a holiday table, with plenty of pan juices for a light homemade gravy.
The night before cooking, remove the chicken from its packaging and pat it completely dry with paper towels. Rub the sea salt all over the skin and inside the cavity, then place the chicken on a tray or in a baking dish. Refrigerate uncovered overnight to help the skin dry out and roast up extra crisp.
The next day, take the chicken out of the fridge 30-45 minutes before roasting. Meanwhile, melt the butter in a frying pan over medium heat, add the olive oil, and cook the leek for about 8 minutes until soft. Stir in the garlic, white wine, thyme leaves, and sage, then simmer until most of the liquid has cooked away. Season lightly and leave the mixture to cool for a few minutes.
Butter a baking dish. In a large bowl, combine the breadcrumbs, Parmesan, beaten eggs, and chopped watercress. Season, add the lemon zest and a squeeze of lemon juice, then fold in the cooled leek mixture. Spoon the stuffing into the dish, drizzle lightly with oil, and cover with foil.
Heat the oven to 220C/200C fan/gas 7. Put the Jersey Royals in a large roasting tray, drizzle with oil, season, and toss well. Pat the chicken dry once more, rub the skin with a little oil, and season with black pepper. Place the chicken in the center of the tray, tuck the lemon halves and thyme sprigs into the cavity, and roast for 30 minutes.
After 30 minutes, place the stuffing on the oven shelf below the chicken and reduce the oven temperature to 200C/180C fan/gas 6. Baste the potatoes with the pan juices, but avoid basting the chicken skin so it stays crisp. Roast for another 30-45 minutes, removing the foil from the stuffing halfway through, until the chicken reaches 75C in the thickest part of the thigh and the potatoes are tender and golden.
Transfer the chicken to a board and rest uncovered for 15-20 minutes. Spoon the potatoes into a warm serving bowl. Skim excess fat from the roasting tray, pour the juices into a saucepan, then add a splash of white wine, the chicken stock, and the cornflour mixture. Simmer until lightly thickened into a gravy, then carve the chicken and serve with the roasted potatoes, stuffing, and gravy.
For the best crackling skin, do not skip the overnight salting and uncovered chilling. If Jersey Royals are unavailable, use other waxy baby potatoes. Leftovers keep well in the fridge for up to 3 days, and the stuffing can be assembled a few hours ahead and chilled until ready to bake.
