Let’s be honest: regular roasted potatoes are fine. But duck fat potatoes? They’re a revelation. The fat renders into shatteringly crisp exteriors while keeping interiors fluffy and cloud-soft. This is the potato dish that steals the show from whatever you serve it with—steak, roast chicken, or just a fried egg.
You only need five ingredients, one pan, and about 20 minutes of active time. No fancy technique. Just potatoes, duck fat, salt, and a little herb magic.
Ingredients

Serves 4 as a side.
- 2 lbs (900g) Yukon Gold or baby potatoes
- 3 tablespoons duck fat (rendered, from a jar or saved from a roast duck)
- 1 teaspoon kosher salt, plus more to finish
- ½ teaspoon black pepper
- 4 cloves garlic, smashed (optional but recommended)
- 2 sprigs fresh rosemary or thyme
- Fresh parsley, chopped (for garnish)
Step-by-Step Instructions
Step 1: Par-Cook the Potatoes
- Scrub potatoes well. If using larger ones, cut into 1.5-inch chunks. Leave small potatoes whole.
- Place in a pot, cover with cold salted water, and bring to a boil.
- Cook for 8–10 minutes—until fork-tender but not falling apart.
- Drain and let steam dry for 5 minutes. This step guarantees crispiness.
Step 2: Heat the Duck Fat
- Preheat oven to 425°F (220°C). Place a rimmed baking sheet in the oven while it heats.
- Carefully add duck fat to the hot pan. Swirl to coat.
Step 3: Rough Them Up
- Tumble the dried potatoes into a bowl. Give them a few good shakes to rough up the edges. Those craggy bits get extra crunchy.
Step 4: Roast to Golden Perfection
- Add potatoes to the hot pan with duck fat. Sprinkle with salt and pepper.
- Roast for 20 minutes. Flip once halfway through.
- Add smashed garlic and rosemary in the last 5 minutes.
Step 5: Finish and Serve
- Remove from oven. Sprinkle with fresh parsley and flaky salt.
- Serve immediately—these wait for no one.

Storage Notes
Best fresh: Duck fat potatoes lose their crunch within hours. Reheat leftovers in a hot skillet or air fryer—never microwave.
Make ahead: Boil and rough up the potatoes a day in advance. Store covered in the fridge. Roast straight from chilled, adding 5 extra minutes.
Duck fat tip: Strain and save used duck fat. You can reuse it 3-4 times.
