Duck Fat Potatoes Crispiest Best Roast Potatoes Ever

No duck fat? No worries! Make my Truly Crunchy Roast Potatoes instead.

Duck Fat Potatoes

You’ve heard of them, you might’ve even seen them on the menu of fine dining restaurants. So – what’s the big deal with Duck Fat Potatoes? Here’s why they’re held as the best roast potatoes in the world!

Crispiest crust that’s thick and craggy, with a deep golden brown colour; Stays crispy rather than going soggy within seconds of coming out of the oven like “normal” roast potatoes; and The best flavour, a pure, clean flavour that doesn’t taste of duck but has a distinctly richer flavour than oil. It’s unique because other animal fats typically have an intense flavour of the animal – like pork fat, which tastes intensely porky.

Plus, it just sounds fancy to say that you’ve made potatoes roasted in duck fat, rather than everyday oil. Right? 🙂 Roasting potatoes in duck fat makes the thickest, craggiest, CRUNCHIEST roast potatoes, in a way that no oil can compare! In actual fat, cooking with duck fat has been a staple in French cooking since the beginning of time. The French understand that duck fat is like bacon – it just makes everything taste better!

Duck Fat

Here’s what Duck Fat looks like. A decade ago, it was something that was only available in gourmet stores and was fairly pricey (>$10 from memory). Nowadays, it’s sold in large grocery stores in Australia (Woolies, Coles, Harris Farms) for around $6 a jar full price – you need 1 x 200g/6.5oz jar for this recipe. Duck fat can be reused – just strain out potato bits, then store in the fridge. It keeps for months and months! I tend to stock up when they’re on sale – they keep in the pantry and have a long shelf life (months, years!). Use it for Duck Confit!

What you need to roast potatoes in Duck Fat

Here’s what you need for Duck Fat Potatoes:

Duck Fat – see and read above; Potatoes – starchy or all rounder potatoes. Australia – Sebago (dirt brushed potatoes, pictured) and Dutch creams are ideal. Also Desiree, Golden Delight, Kennebec, King Edwards, Pontiac. US – Russets are best, Yukon Gold also ideal. UK – Maris Piper potatoes Semolina – a little secret ingredient for subtle extra crunch, learnt from Nigella! Semolina is a coarse ground yellow wheat that’s used for making (amongst other things) pasta. It’s the perfect size to “meld” into the coating of the potatoes so you can’t taste it separately but you get the benefit of the extra crunch. If you can’t find it, leave it out. There’s really no substitute – even fine ground cornmeal is too coarse (I’ve tried). Don’t worry, it’s like that extra little finishing touch – but I’ve made duck potatoes plenty of times without (and 99% sure most restaurants do too! More salt than you expect. Potatoes take a lot of salt!

What to serve with Duck Fat Potatoes

The traditional way to serve Duck Fat Potatoes is on the side of roasts. The only thing you need to be mindful of is that you want to serve these potatoes fresh out of the oven to maximise the time they stay crunchy and crispy. So assuming you’ve only got one oven like me, you need to choose roasts that hold up to resting for the 45 – 50 minutes the potatoes take to roast. My favourites include:

Slow Roasted Lamb Shoulder Slow Roast Leg of Lamb and classic Roast Lamb Leg Marinated Roast Beef Juicy Whole Roasted Turkey

I avoid the following:

Pork Roast with Crispy Crackling – because the crackling will soften if covered for that length of time; Roast Chicken – it’s smaller so optimum maximum rest time is around 20 minutes.

From a practical perspective, Duck Fat Potatoes are ideal to serve on the side of slow cooker roasts because then you don’t need to deal with the oven battle. Here are my favourites:

Lemon Garlic SLOW COOKER Roast Chicken Slow Cooker Roast Lamb Leg Slow Cooker Pork Loin Roast Slow Cooker Pot Roast
