Most people have eaten roast potatoes, but how about roasted potatoes made with duck fat? The extra ingredient gives an added depth of flavor along with a thick, crispy skin. The deep golden-brown skin maintains its crisp texture, unlike many recipes that use other types of oil.

Ducks are high in saturated and monounsaturated fats, which is useful in the kitchen. During cooking, duck fat remains stable, preserving its taste and ensuring that any ingredient it combines with also takes on that flavor. You’ll notice that food cooked in duck fat doesn’t taste greasy, which is an added bonus.

Where can I find duck fat?

Do you enjoy cooking duck at home? Your best option is to keep the leftover juices from the pan you used to cook the poultry. It will be a clear, runny liquid that can easily be poured into a container for later use. Once refrigerated, the liquid hardens and turns white. Use these leftovers for adding flavor to meat or vegetables.

If you don’t usually cook duck, then your best option is to pay a visit to your local supermarket. In the chilled section, you will usually find pots of duck fat available. Alternatively, chicken shops often stock this item. Traditionally, this was an expensive product to buy. But, in recent years the price has become much more reasonable.

It’s important not to cook this dish in advance as the crispy exterior will turn an unpleasant soft and chewy texture. Be sure to time your potatoes to be served immediately after cooking them.

Do you have leftover duck fat?

If you’re looking for new ideas for how to use duck fat, then a confit is one of the best uses we can recommend. This technique requires enough liquid fat to submerge the meat or vegetables you want to cook. For example, add a few pieces of chicken to a dish then submerge them in liquid fat. Now you can slow-cook the meat on a low heat. The result is tender meat that doesn’t dry out.

Boil before roasting

If you boil the vegetables before adding them to the oven them, it results in perfectly cooked insides. Be careful not to take them too far in the water as they’ll become dry and floury.

Choose the right potato

Choosing the right potato will make a big difference to the final result. The best options are flour potatoes like Maris Piper or King Edward. If you want to read all about the various types of potatoes, then be sure to check out our helpful guide: popular potatoes and their uses.
