What Is Duckling and How Can I Use It?

Duckling is easier to cook with than it looks. Here's how to choose, use, and store it, what to substitute, and 11 recipes to get you started.

Key Points

A duckling is a young, tender domestic duck, almost always a Pekin under eight weeks.
Score and slowly render the fatty skin so it crisps instead of turning rubbery.
Cook the breast to a rosy 135°F (57°C); cook legs to 175°F (80°C).
Save the rendered fat: strained, it keeps six months and makes superb roast potatoes.
Cut duck's richness with sharp fruit like cherries or orange, the duck a l'orange idea.

What is duckling?

A duckling is a young domestic duck, usually a Pekin, slaughtered under about eight weeks old. The name signals tenderness more than size: the meat is finer and milder than that of an older bird, which is why most ducks sold for roasting are labeled duckling.

Duck is all dark meat, even the breast, with a deeper flavor than chicken and a thick layer of fat under the skin.

That fat is not a flaw to trim away. Rendered slowly, it is one of the best cooking fats in any kitchen.

Cooking a Duckling

Everything about cooking duck comes down to managing that fat. The skin sits over a heavy fat layer that has to render out, or you end up with flabby, greasy skin instead of a crisp one.

Start by scoring the skin in a crosshatch, cutting through the fat but not into the meat. The cuts give the fat an escape route and let the skin contract and crisp. Prick the breast skin the same way before roasting a whole bird.

For a whole duckling, roast at a moderate 325 to 350°F (160 to 175°C) and pour off the rendered fat two or three times along the way.

Cantonese Roast Duck and Roasted Wild Duckling both build their crisp skin this way, and Tea Smoked Duck with Smoked Walnuts adds a smoking step over the same rendered base.

For duck breast, start it skin-side down in a cold dry pan over medium heat. Let the fat render for 6 to 8 minutes until the skin is deep brown and crisp, then flip for a minute or two to finish.

Save every spoon of the fat that pours off. It keeps for months in the fridge and makes the best roast potatoes you will cook all year.

Doneness and Pairing

Duck breast is best cooked like a steak, to a rosy medium-rare around 135°F (57°C). Push it past medium and the lean breast turns liver-dry.

Legs and thighs are the opposite case: they need long, gentle cooking to about 175°F (80°C) so the connective tissue melts, which is exactly what confit and slow braises do.

Duck's richness wants something sharp or sweet to cut through it. The classic foil is fruit such as sour cherries or orange, which is the whole idea behind duck a l'orange.

Green peppercorns and star anise both stand up to the fat, and Duck with Pine Nut Wild Rice shows how earthy grains balance it.

The most common mistake is rushing the render. Crank the heat to brown the skin fast and the fat underneath stays soft and rubbery; low and patient is the only way it crisps properly.

Substitutes

Nothing else eats quite like duck, but a few birds fill the same role. Goose is the closest match. It is even fattier, and it takes the same scoring and slow-render treatment on a larger scale.

Chicken thighs, always the dark meat, are the everyday stand-in for flavor, though they lack the fat layer that defines duck. For a recipe built on confit or braise, bone-in chicken thighs adapt well.

Pork belly is a useful swap when the dish is really about rendering a thick fat cap to crisp, as in many Cantonese roasts.

Buying and Storage

Most ducklings are sold frozen and whole, around 4 to 6 pounds, often with the neck and giblets tucked inside. Look for unblemished skin and a good fat layer. A fresh bird should smell clean, never sour.

Thaw a frozen duck in the fridge, allowing roughly 24 hours for every 4 to 5 pounds; never thaw it on the counter. Once thawed, cook it within two days and keep it on the bottom shelf so nothing drips below it.

Cooked duck keeps three to four days in the fridge. Rendered duck fat is the real keeper: strained into a clean jar, it lasts up to six months refrigerated and freezes almost indefinitely.
