Remove the duck breast from the fridge and allow it to come to room temperature.
Score the skin of the duck, or cut in a crisscross pattern. This will allow the fat to render when cooking. If you'd like your duck fattier, make fewer cuts in the skin.
Season the duck generously with salt and pepper
Preheat the oven to 350°F
Place the duck skin-side down on an ovenproof safe pan (that has not been heated). Turn the heat on the lowest setting. Gradually turn the heat up until you notice a gentle bubbling of the fat. Maintain the temperature at this level for a 10-15 minute period to allow the fat to render. The duck's internatl temperature should read 125°F.
After rendering the fat, turn up the heat and cook the duck for about 2-3 minutes. The skin should become a crispy, golden color.
Flip the duck on the opposite side and cookfor 1-2 minutes.
Finish the duck by placing the pan in the oven for 7-8 minutes. When the duck is finished cooking it should be slightly springy when pressed. For medium-rare cook until a temperature of 130°F is reached. For medium, 140°F and for well done 155°F.
Allow the duck to rest for 5 minutes before cutting
Enjoy!
