How To Make Sous Vide Duck Breasts
The sous vide cooking technique is perfect for duck breasts because it gets the meat to the perfect temperature while retaining the natural moisture in the meat. The low and slow cooking time also tenderizes the meat. A good sear after the water bath results in crispy skin while keeping the inside medium-rare. Follow the steps below for perfectly medium-rare and tender duck breasts!

- Step 1: If your duck breasts have a thick layer of fat under the skin, score the skin of each duck breast with a sharp knife in a diamond pattern. If your duck breasts do not have a layer of fat under the skin, don't worry about scoring them.

- Step 2: Season duck breasts all over with salt and pepper.

- Step 3: Place sage leaves and butter in the vacuum bag. Then, place the duck breasts in the bag in a single layer on top of the butter and sage.

- Step 4: Seal the bag with a vacuum sealer.

- Step 5: Preheat the sous vide machine to 120 degrees F. Place the sous vide bag in the preheated water bath and cook for 1 hour.

- Step 6: Remove the bag from the sous vide bath. Cut the bag open with scissors and remove the meat. Remove the sage leaves and carefully pat the meat dry with a paper towel.

- Step 7: Re-season with salt and pepper if it looks like it has lost the seasoning.

- Step 8: Preheat a cast-iron pan over high heat. Once the pan is really hot, add the duck fat and let it melt.

- Step 9: Immediately add the duck breasts, skin side down. Cook for 1-2 minutes or until the skin is crispy and golden brown.

- Step 10: Flip and cook an additional 1-2 minutes, or until the internal temperature reaches 125-130°F for medium-rare.

- Step 11: Remove the breasts from the pan and let them rest on a cutting board while you prepare the sauce.

- Step 12: Slice duck breasts into ½" slices.
Pro Tip
If your vacuum bags have a smooth side, place the skin on the smooth side so that the pattern doesn't change the appearance of the skin.
How To Make Blackberry Sage Sauce
This blackberry sage pan sauce is truly the best accompaniment to wild duck meat. It has everything you want in a sauce - it's tangy, sweet, savory, salty, earthy, and packed with flavor. Follow the instructions below!

- Step 1: Turn the pan heat down to medium. Add butter to the pan and swirl to coat the pan.

- Step 2: Add in shallots and sage. Cook for 1-2 minutes or until shallots are starting to soften and the sage is fragrant.

- Step 3: Add in blackberry brandy and red wine to deglaze the pan. Bring to a simmer and season with salt and pepper.

- Step 4: Stir to combine, then add in the blackberries. Gently squish the blackberries while they're cooking. Simmer for 10 minutes or until the sauce is reduced by half, stirring frequently.

- Step 5: Strain the sauce through a fine mesh strainer. Use a spoon to squish the blackberries through the strainer, leaving the seeds and skins behind.

- Step 6: The sauce should be the consistency of a thick syrup. If it is not thick enough, return the strained sauce to the pan and simmer, stirring frequently, until the desired consistency is achieved. Remove the sauce from the pan immediately, or it will continue to reduce.
Pro Tip
This sauce is also delicious with steak and meaty fish like salmon. You can cook your steak or fish in a cast iron pan, then follow the same instructions for the sauce.

Recipe FAQs
Duck breasts do well with sous vide cooking or searing in a cast iron pan.
Duck is more similar to red meat than it is to poultry. It has a very rich, meaty flavor and should be cooked like a steak. Wild duck typically has a stronger flavor than domestic duck, depending on the species of duck used. Some have a stronger flavor than others.
Many recipes will tell you to cook duck breasts at 135 degrees F sous vide. But, if you want to get crispy skin and a good sear after the sous vide cooking, 120 degrees F works great. This gives you 10-15 degrees of wiggle room to cook your duck the rest of the way in a cast iron pan.

- Fresh blackberries are used for this recipe but you can also use frozen, thawed blackberries.

- Using a sous vide machine takes the guesswork out of sous vide cooking by keeping the water at a precise temperature, but it can be done without one. Check out this resource on sous vide cooking without a machine.
- Instead of a vacuum sealer, the water displacement method uses water to remove the air from a resealable plastic bag instead of using a vacuum bag.
- If your vacuum bags have a smooth side, place the skin on the smooth side so that the pattern doesn't change the appearance of the skin.
- This sauce is also delicious with steak and meaty fish like salmon. You can cook your steak or fish in a cast iron pan, then follow the same instructions for the sauce.













Alan in Toulouse says
Really impressed with your recipe! Love the idea of pairing blackberries and sage. Have to try that. I live in the SW of France where we have fattened ducks. I figured out that I really need to score the fat and fry a couple of minutes on both sides to render as much fat as I can before putting the breasts in the sous vide. Then I dry them and sear again as you do in your recipe. Thanks again for the inspiration. Will try this sauce in September 🙂

Thank you so much, Alan! Your fatty ducks sound lovely but I typically only have access to wild ducks that are more lean. I hope you enjoy the sauce! 😊
