Crispy Duck Fat Potatoes with Rosemary Sea Salt

Potatoes cooked in duck fat and sprinkled with rosemary sea salt is a match made in heaven.  Yes…..the French really know what they are doing.  This is a classic French dish that pairs so well with steak or even with something like Mussels or a bold chicken dish.

“Why duck fat?” you may ask. It has a higher smoke point than olive oil and so it’s good for roasting at high temperatures to get that crispy outside on the potato.  But more importantly it packs in a ton of flavor. And duck fat isn’t gamey, like you’d expect, but more of an earthy undertone that gives a real depth of flavor to the potatoes.  Even my non-gourmet ten-year-old loved them.  You could use lard instead of duck fat if you can’t find it.  Or bacon fat.  The lard would not have the flavor and the bacon grease would give it a little porky flavor so I prefer this duck fat version but sometimes you just have to go with what you can get.

I decided to make a Rosemary Sea Salt instead of just sprinkling rosemary and salt on separately.  The real reason behind that decision is that if you crumble the sea salt ( I used Maldon) with the fresh Rosemary with your fingers you are releasing the oils from the Rosemary into the salt and creating the perfect, crumbly mixture.  So the ratio of salt to rosemary is just right and the salt is really flavored by the rosemary.  Okay.  A little neurotic.  But its a nice touch.  And an extra can be saved in an air-tight container for other delectable dishes.

As for the potatoes…..I wanted to do something that was more refined in presentation so I decided to slice them about 1/2 inch thick and then roast them.  You could just opt to smash the baby potato (after you par boil it) and add to the duck fat and roast it that way, too.  Less time consuming and more rustic.  Up to you!

I think the par boil step is an important one because the potatoes cook more evenly that way. You don’t risk getting a tough center.  Just for about 8 minutes.  You definitely don’t want to overcook them but just a slight edge off the raw potato makes a world of difference.  You can make this step ahead of time so that it’s not so time intensive at the last minute.

For presentation I removed them from the roasting pan onto a serving platter and added a fresh sprig of rosemary.  But for a family dinner or a more rustic occasion just serve in the roasting pan and save yourself a step.  I can taste the juicy steak that I am going to serve with these potatoes right about now…..

  • 3/4 Tablespoon flaky sea salt (Maldon recommended)
  • 1 Tablespoon fresh rosemary, finely chopped, plus more for garnish
