Duck is like the pork of poultry, it has such great flavor and there’s almost nothing better than the skin crisped up. It’s my favorite bird to roast, and yet it’s perhaps the trickiest to do right. “Right” in my book is a whole bird with tender moist meat, a minimal amount of sub-dermal fat and a thin crispy skin coated in a sweet caramelized glaze.
To achieve a crisp skin, some recipes call for cooking the duck at a high temperature for an inordinately long time. While they do indeed produce wonderfully crisp skin, the drumsticks end up like duck jerky and the breasts become chalky and dry. Other recipes have you steam the duck then cut it up, roasting the legs and breasts separately. This works a little bit better as you can remove the breast meat earlier, but to me, this is not a roast. If you’re going to cut the duck up, why not just confit the legs and pan sear the breast?
I wanted a real roast that showed up at the table in one piece with succulent breasts, tender legs, and a crispy glazed skin. Most importantly, it’s a roast, so it had to be simple, without involving culinary acrobatics or acts of God to create. Desperate for a miracle, I hit up the omniscient Internet, only to be disappointed by the lack of good solutions.
In the end I decided to do what I do best: ignore all the rules and make up my own. When it comes to duck, conventional wisdom, like bringing the roast up to room temperature, works against you. Another counter-productive “rule” about roasting poultry is to avoid obstructing the entrance to the body cavity so hot air can circulate inside the bird. Both these result in more even cooking, which is desirable with most roasts, but in the case of duck, you want it to cook unevenly.
To understand this, you have to think about the anatomy of a typical Long Island duck. Between the skin and the meat, there is a very thick layer of fat. The best way to get rid of the fat (and crisp the skin in the process) is to cook it at a high temperature until the fat is rendered out. The problem is that the amount of time it takes to render out most of the fat is far too long for the meat underneath. That’s why you want the duck to cook faster on the outside than it does on the inside.
By chilling the duck and sewing up the body cavity, the outer layer (i.e. the skin and fat) gets very hot, while the meat underneath takes a lot longer to heat up. This means you get the fat rendered out, the skin crispy, and your breasts comes off the roast a lovely shade of pink.
The one other problem I have with most roast duck recipes is that they have you drain the fat every 30 minutes. It’s considered a necessary step, otherwise the oil gets too hot and starts to smoke. The problem is that it’s messy, dangerous, and a big hassle. I’ve found that by continuing to add water to the pan, it keeps the temperature of the accumulating oil low enough that it does not smoke. At the end, you can still save the wondrous duck fat for other uses by pouring it through a tea strainer. You’ll have some liquid under the fat, but it doesn’t matter because it will separate, and the fat on top will harden in the fridge. You’ll get a few cups of fat and about a cup of concentrated duck juices by doing this, both of which can be used for something else.
This is optional, but you can brine the duck first in a solution of water, sugar and salt. Click here for a brine recipe. This will flavor the meat all the way to the center.
Ingredients
-
2270
grams
Long Island duck (a.k.a. Peking)
-
2
teaspoons
Dijon mustard
-
1/4
cup
mild honey
-
2
teaspoons
caraway seeds
-
1
teaspoon
kosher salt (halve if using regular salt)
Steps
-
Prick the duck all over with a sharp trussing needle. Try not to prick it through the meat, you just want to open up the skin so the fat underneath can render out. Pour a kettle of boiling water over the duck to tighten up the skin (you'll see it shrinking).
-
Pat the duck as dry as possible using paper towels, then put it on a rack and stick it in the fridge for at least 1 hour. You want the duck to be cold with very dry skin when it goes into the oven as it will take a while to render out the fat from under the skin without overcooking the meat.
-
Preheat the oven to 425 degrees F. Take the duck out of the fridge and prick the skin all over again making sure you don't pierce the meat. Pat the duck dry again with paper towels. If you haven't brined the duck, rub a few tablespoons of kosher salt on the inside and outside of the bird. Sew the body cavity shut or you can use toothpicks or skewer to do it. You want the duck to cook from the outside-in, so sewing the cavity shut prevents hot air from cooking the inside.
-
Pour 2 cups of water in the bottom of a roasting pan with a V rack and place the duck on the rack, breast-side up. Roast for 35 minutes. Remove the duck from the oven and insert a wooden spoon into the body cavity to flip it over so the breast-side is down. Add another cup of water and roast for another 40 minutes. If the fat starts spatering excessively or begins smoking at any time during the roasting process, add more water to the pan.
-
Make the glaze by adding the mustard, honey, caraway and salt to a small bowl and stirring to combine (microwaving it for a bit will make it easier to mix). Remove the duck from the oven and use a pastry brush to glaze the duck. Flip the duck over, and brush the glaze on the breast-side. Add more water to the pan if it needs it, and put it back in the oven for a final 20-30 minutes or until the glaze is a nice dark brown, and the skin is crispy.
-
Serve the duck immediately (if you let it rest, the skin will get soggy).

Hi Jack, welcome! Stuffing the duck should work well for slowing heat transfer to the center. Just make sure the stuffing reaches a safe temperature if you’re planning on eating it.

Finger licking good!
btw, what kind of mustard do you use within this recipe, powdered or the ready salad dressing ???
i learn a lot things here……

Hi Dedy, I used dijon mustard, but any prepared mustard should work.
Mia says
I just love the simple Dijon mustard from trader Joe’s, it is delicious and costs maybe $2 for a 13 oz jar

Thanks for sharing Mia!

I was making duck for the first time, and at Christmas too so I was concerned that it had to turn out right first time. Hats off to you – this recipe/technique was perfect. Delicious skin and awesome, succulent meat. Many thanks for sharing.

Sides? What would you recommend serving with this?

Mashed potatoes are always great with roasts and in the photos, this is served on a bed of Kale with Pine Nuts and Raisins ( https://norecipes.com/kale-recipe/ ).
