The best way to reheat Peking duck is in a hot oven at 375–400°F for 5 to 7 minutes, which re-crisps the skin without drying out the meat. The key challenge is restoring that signature crackly skin while keeping the flesh tender underneath, and the method you choose matters more than you might expect.
Before You Start
Take your leftover duck out of the fridge about 15 to 20 minutes before reheating. Cold meat thrown into a hot oven heats unevenly: the outside overcooks while the center stays cold. If your Peking duck was stored as a whole or half bird, separate it into smaller pieces or individual slices so heat reaches the meat faster and the skin gets maximum exposure to dry air.
Pat the skin dry with a paper towel. Any surface moisture will steam instead of crisp, which is the opposite of what you want.
Oven Method (Best Overall)
Preheat your oven to 375–400°F. Line a baking sheet with foil and give it a light coating of spray oil to prevent sticking. Lay the duck pieces out in a single layer with space between them so air circulates around each piece.
Reheat for 5 to 7 minutes. After the 5-minute mark, check every minute or so. The skin can go from golden to burnt quickly at these temperatures, and the thin slices typical of Peking duck heat through faster than a thick roast. You want the skin sizzling and taut, with the meat warmed through but still juicy. If you have an instant-read thermometer, the internal temperature should reach 165°F for food safety.
Air Fryer Method (Crispiest Skin)
An air fryer is essentially a small convection oven, and it excels at crisping duck skin because the circulating hot air hits the surface from all angles. Place your duck pieces skin side up, keeping them as flat as possible so the skin faces the heating element directly. For leftover sliced Peking duck, 3 to 5 minutes at 375°F is usually enough. A whole half duck takes closer to 15 to 20 minutes, but most people reheating Peking duck leftovers are working with sliced portions.
Don’t stack pieces. The whole point is maximizing airflow around the skin. If you need to reheat a large amount, work in batches.
Stovetop Searing (Quick and Effective)
If you want crispy skin without turning on an oven, a skillet works well. Heat a pan over medium heat. You can add a small amount of oil, but duck skin renders its own fat, so you won’t need much. Lay each piece skin side down and let it sit undisturbed for 5 to 7 minutes until the skin turns crisp and deep golden. Then flip and heat the other side for 2 to 3 minutes until warmed through.
This method gives you the most control because you can see and hear the skin crisping in real time. The downside is that it only works well with flat, individual pieces. Irregularly shaped chunks won’t make good contact with the pan surface.
The Restaurant Trick: Hot Oil Basting
Chinese restaurants that serve Peking duck often reheat it by ladling hot oil over the skin repeatedly, not submerging it, just basting. This delivers intense, even heat to the surface while keeping the meat from overcooking. You can replicate this at home by heating a few tablespoons of neutral oil in a wok or deep pan until it shimmers, then spooning it over the duck pieces on a wire rack. It takes only a minute or two and produces a remarkably crispy result. It’s messier than the oven approach, but if you care about getting the skin as close to freshly roasted as possible, this is the way.
What to Avoid
The microwave is the worst option for Peking duck. It heats by agitating water molecules, which means it effectively steams the skin from the inside out, turning it soft and rubbery. The entire appeal of Peking duck is the contrast between crackling skin and tender meat, and a microwave destroys that in seconds. If your only goal is to warm the meat and you don’t care about texture, a microwave works in 30 to 45 seconds, but you’ll lose everything that makes Peking duck special.
Reheating the Pancakes
The thin flour pancakes that come with Peking duck need gentle moisture and heat to become pliable again without turning tough. The best method is steaming: set up a steamer basket over simmering water and steam the pancakes for 20 to 30 seconds. They go from stiff to soft very quickly, so don’t walk away.
If you don’t have a steamer, a dry skillet on low heat works. Warm each pancake for just a few seconds per side. Too much heat or too long on the pan makes them rubbery and brittle. A damp paper towel wrapped around the stack, microwaved for 10 to 15 seconds, is another option, though results can be uneven. The hoisin or plum sauce doesn’t need reheating at all. It’s fine served at room temperature straight from the fridge, and warming it risks thinning it out too much.
Keeping the Meat Moist
Duck meat is richer and fattier than chicken or turkey, which gives you a little more margin for error. But sliced Peking duck is thin, so it can dry out fast under high heat. The single most important thing is not to overcook it. Set a timer. Check early. Pull it from the heat as soon as the skin crisps and the meat is hot.
If you’re reheating larger pieces rather than thin slices, you can tent them loosely with foil for the first few minutes to trap some steam around the meat, then remove the foil for the last 2 minutes to let the skin crisp. This two-stage approach keeps the flesh from losing too much moisture while still delivering the texture you’re after. Spacing the pieces apart on the baking sheet also helps, because crowded pieces steam each other instead of crisping independently.
