I’ll be honest: I normally don’t roast ducks this way. I really like my breast meat medium-rare to medium, and on most wild ducks, which have a thin layer of fat, this is easily doable by roasting a wild duck over very high heat – up to 500°F. This crisps the skin quickly while leaving the meat rare-to-medium. If you have a normal wild duck, use this method.
But when life gives you a really fat wild duck, or any typical domesticated duck, this is the way to go.
The reason is fat. Fat is an insulator, and in a duck it’s all underneath the skin. You need to render that fat or the skin will never get crispy. And rendering fat from a porky duck takes time — so much time that your breast meat will be fully cooked by the time it’s ready (The legs and wings will be perfect, though).
This slow roast method is very old school. It’s the way all of Europe has been roasting ducks and geese for a millennium or longer. And it’s a great method, except for the fully cooked breast meat. It will still be moist because it’s been bathed in its own fat for an hour, but it is nowhere near as good as medium-rare breast meat, at least to my taste.
My advice for when you make your ducks this way is to roast them alongside lots of root vegetables, the more varied the better. And think about a gravy or a sauce to go with it. I have a large selection of wild game sauces here you can choose from. I might think about the maple-bourbon gravy for starters…
Slow Roasted Duck
This recipe works with any sort of waterfowl. Domestic ducks typically serve two to four. As for wild birds, a mallard, canvasback, redhead, gadwall or pintail will serve two (if you have other things on the plate), a goose four and a wood duck, bluebill, wigeon, ringneck or teal one.
Prep Time: 30 minutes, mostly rest time
Cook Time: 1 hour
- 1 domesticated duck or 2 very fat wild ducks (see above for species variations)
- 1 tablespoon kosher salt
- 1 lemon, cut in half
- 4 sprigs sage, rosemary, parsley and/or thyme
- Preheat oven to 350°F. Take the ducks out of the fridge. Using a needle or a very sharp knife point, prick the skin of the duck all over — but be sure to not pierce the meat itself, only the skin. This helps the fat render out and will help crisp the skin. Pay special attention to the back, the flanks, and the very front of the breast.
- Rub the lemon all over the duck and stick it inside the cavity. Liberally salt the bird; use a little more salt than you think you need. Stuff the cavity with the herbs. Let the duck sit out for about 30 minutes to come to room temperature.
- When you are ready to roast, put the duck on an iron frying pan or other ovenproof pan and surround it with root vegetables. Set the pan in the oven. Cook domesticated ducks for 1 hour like this. Cook large wild ducks like mallards and pintails for 45 minutes. Small ducks (wood ducks, wigeon, teal, ruddies, etc.) only need 40 minutes. If you are roasting a goose, increase the roasting time to 1 hour, 20 minutes. After the allotted time, take the pan out of the oven and set the ducks on a cutting board to rest. Spoon any fat that has accumulated over the vegetables and salt them well. If the veggies are ready to eat, remove them. If there is a lot of excess fat, spoon it off.
- Now turn the heat up to 450°F. When the oven hits this temperature, roast the birds for 15 to 20 more minutes, or until the skin is crisp. The reason you take the bird out of the oven is because a) the resting time helps redistribute the juices in the bird midstream, and b) you are crisping skin without totally overcooking the duck by only returning it to the oven when it is hot.
- Remove from oven and let the birds rest. You’ll only need 5 minutes resting time for small birds, 10 minutes for large ducks, and 15 for geese.
