This is my method for getting potatoes with a shatteringly crispy crust and a fluffy interior every time. The two non-negotiable steps are parboiling the potatoes in acidic water and getting your fat screaming hot before the potatoes go in the oven.

Ingredients
2poundsRusset potatoespeeled and cut into 1 1/2-inch chunks

1tablespoonwhite wine vinegar

2tablespoonsolive oil
5-6 cloves garlicunpeeled and smashed
3-4 sprigs fresh rosemary
A handful of fresh thyme sprigs
1teaspoonsmoked paprika
Freshly ground black pepper
Freshly chopped parsleyfor serving
Method
Cover peeled potato chunks with cold salted water and vinegar.
Boil 7-8 minutes until edges are tender but centers firm.
Drain, steam dry, then shake colander to rough up surfaces.
Preheat oven to 425F.
Heat duck fat, oil, garlic, and herbs on baking sheet in oven 5-7 minutes.
Add potatoes to hot fat, toss with paprika, salt, and pepper.
Roast 40-50 minutes, flipping every 15 minutes until deeply golden and crispy.
Remove herbs, squeeze roasted garlic over potatoes if desired.
Season to taste, garnish with parsley and serve hot.
Notes
Roughing up potato surfaces creates extra-crispy edges. Duck fat can be substituted with beef tallow.
