Whole Roast Duck

Most whole ducks sold for roasting are Pekin (also labelled Long Island or White Pekin), running 1.8–3.2 kg (4–7 lb) with a thin, even fat cover under pale skin. Check the packaging date, look for skin that is dry rather than slick or grey, and press the breast gently — it should spring back rather than feel waterlogged. A bird sitting in excess liquid in its tray has likely been frozen and thawed less carefully than you'd want; it will still cook safely, but it will render less cleanly.

Buy by weight, not by "serves four" labelling. A whole duck yields far less cooked meat per kilogram than chicken — plan portions with the serving calculator before you shop, since the honest yield surprises most first-timers.

Unwrap the duck as soon as you get it home, pat it dry, and set it uncovered on a rack over a tray in the fridge for at least 8 hours and ideally overnight (up to 24 hours). This single step does more for crisp skin than any oven trick — it pulls surface moisture out so the skin starts dry instead of steaming in the first twenty minutes of roasting.

Before it goes in the oven, cut away the loose flaps of neck skin and the thick pads of fat just inside the cavity opening — render these separately in a small pan rather than leaving them to smoke onto the bird. Then either prick or score the fat cap: pricking uses a skewer or fork tip at a shallow angle over the thighs, back and lower breast, just deep enough to open the fat without reaching the meat; scoring uses a paring knife in a light crosshatch over the breast skin only. Either works — pricking gives more escape routes for fat over a large area, scoring gives a more deliberate pattern on the breast. Don't do both hard, and never cut into the meat itself; that lets juices out instead of fat.

A light truss — tying the legs together and tucking the wingtips under the body — keeps the bird compact and the breast from splaying, which helps even cooking. It doesn't need to be tight or elaborate.

Set the duck breast-side up on a roasting rack over a tray deep enough to catch the fat it will render — a whole duck can release 1–2 cups (240–475 ml) of fat over a roast, and an overflowing tray is a real fire risk in a hot oven.

Two oven strategies both work well. The low-render-then-hot-finish route starts at 300–325°F (149–163°C) for the first hour or so to melt fat gently without hardening the skin, then finishes at 425–450°F (218–232°C) for the last 20–30 minutes to crisp and colour it. The steady-temperature route holds a single moderate oven, around 350°F (177°C), for the whole roast and relies on time and the fat cap alone for crisping. The two-stage method generally produces crisper skin; the steady method is simpler to manage if you're also cooking other dishes. Neither is "correct" — treat the times below as planning ranges, not guarantees, and use the cooking-time planner to set a starting point for your bird's weight.

Drain the tray of rendered fat once or twice through the roast — carefully, with the bird held back with tongs or a second pair of hands — so it doesn't smoke or spatter once it gets hot enough to shimmer.
