Next time you roast potatoes, try duck fat instead of oil or butter. It will open up a new world of flavors and aromas. And once you tasted these roasted duck fat potatoes, you will not go back to your traditional recipe.
Wash the potatoes and transfer them to a pot and add water. Bring them to a boil, reduce the heat and cook for about 10 minutes or until the potatoes are just fork tender. You don't want them too soft. (note 1)
Preheat the oven to 400 degrees F.
Drain the potatoes and allow them to cool just a little bit, so you can handle them. Cut them in half or quarters and place them on a baking sheet.
Use your hands and coat the potatoes pieces with the duck fat. Sprinkle with salt and pepper and a little bit of finely chopped rosemary. (note 2 and 3)
Roast the potatoes for about 15 minutes and then reshuffle them and roast for another 15 minutes or until golden and crispy.
Remove from the oven and sprinkle some coarse salt if needed and some rosemary for garnish.
Notes
Don't peel the potatoes, leave the skin on. It's tastier and healthier.
One tablespoon of duck fat may even be too much.
Be easy on the rosemary. It is a very strong herb that can be overpowering.
