Can You Use Leftover Duck Fat for Cooking?

Storing and Reheating Duck Fat

When storing leftover duck fat, make sure to refrigerate it at a temperature below 40°F (4°C) within two hours of cooking. If you plan to use it within a week, it’s best to store it in a sealed container in the fridge. If you won’t be using it for an extended period, consider freezing it. When reheating duck fat, place the container in a water bath set to 180°F (82°C) for about 30 minutes, or until the fat reaches a smooth consistency.

Using Duck Fat for Searing Duck Breast

Reheated duck fat can be used as a substitute for oil when searing duck breast. To achieve a crispy crust, preheat a skillet or cast-iron pan to 400°F (204°C) over medium-high heat. Pat the duck breast dry with a paper towel, then sear it in the duck fat for about 3-4 minutes on each side, or until it reaches your desired level of doneness.

Adding Duck Fat to Confit Legs and Other Recipes

Duck fat can also be used to make confit legs, a traditional French dish. Simply rub the duck legs with salt, herbs, and spices, then submerge them in the duck fat in a preheated oven at 275°F (135°C) for about 2-3 hours, or until they’re tender and fall-off-the-bone. Reheated duck fat can also be used as a finishing touch for dishes like bacon-wrapped duck breast, where it adds a rich, buttery flavor. To make an orange glaze, mix the warmed duck fat with orange juice, honey, and a pinch of salt, then brush it over the duck breast during the last few minutes of cooking.
