Duck Fat Potatoes Recipe

I made Crispy Duck Fat Potatoes so outrageously golden on the outside and silky inside that I’m selfishly keeping this one for myself.

I can’t quit thinking about crispy duck fat potatoes. I adore the way the skin shatters into golden shards while the inside stays creamy and stubborn.

I love how a spoonful of garlic and a twig of fresh thyme cuts through the richness, and how those simple aromatics make a Duck Dinner feel like something worth dressing up for. Duck Fat Potatoes as a side are shamelessly indulgent, a little loud and seriously noble.

I’m obsessed with serving these with roast meat or stacking them into a pile so everyone fights for the last one. Pure, stupid good.

No regrets.

Ingredients

• Potatoes: crispy edges, fluffy centers, it’s the heart of the plate.
• Basically duck fat adds rich, silky crunch and amazing brown color.
• Kosher salt seasons deeply, helps crust form, not just salty.
• Freshly ground pepper gives little pops of heat and aroma.
• Garlic cloves roast into sweet, mellow garlic that perfumes every bite.
• Plus thyme or rosemary brings herby brightness, earthy pine notes.
• Dried thyme works fine when fresh isn’t available, still tastes homey.
• Parsley adds green freshness and a clean finish, if you want.
• Flaky sea salt at the end gives that irresistible crunch hit.

Ingredient Quantities

• 2 1/2 to 3 lb Yukon Gold or russet potatoes, washed (about 1.1 to 1.4 kg)
• 4 tablespoons duck fat (about 60 g)
• 1 1/2 teaspoons kosher salt, plus more for finishing
• 3/4 teaspoon freshly ground black pepper
• 4 garlic cloves, peeled
• 2 to 3 sprigs fresh thyme or rosemary, or 1 teaspoon dried thyme
• 2 tablespoons chopped fresh parsley for garnish (optional)
• Flaky sea salt for finishing (optional)

How to Make this

1. Preheat oven to 425°F (220°C). Put the duck fat in a large roasting pan or rimmed baking sheet and place it in the oven so the fat melts and gets hot while you prep the potatoes.

2. Cut 2 1/2 to 3 lb potatoes into even chunks about 1 to 1 1/2 inches. If using russets you can peel them, Yukon Golds can be left with skin on. Try to keep pieces similar so they cook evenly.

3. Put the potato chunks in a large pot, cover with cold water, add 1 1/2 teaspoons kosher salt, bring to a boil, then simmer 8 to 10 minutes until edges are just tender but centers still firm. You want them parboiled not falling apart.

4. Drain well and return potatoes to the hot pot. Shake the pot gently for 30 seconds to a minute to rough up the outsides. This creates a starchy, fluffy surface that crisps really nicely.

5. Remove the hot roasting pan with melted duck fat from the oven carefully. Add the potatoes in a single layer, turning to coat them in the fat. If the pan seems crowded use two pans so potatoes roast instead of steam.

6. Toss in 4 peeled garlic cloves and 2 to 3 sprigs fresh thyme or rosemary, or 1 teaspoon dried thyme. Sprinkle with 3/4 teaspoon freshly ground black pepper. Spread everything out so pieces have space.

7. Roast in the oven for 35 to 45 minutes, turning once or twice with a spatula so they brown evenly. Roast until deep golden and very crisp on the outside and creamy inside.

8. Taste and add more kosher salt if needed. Remove garlic cloves and herbs if you want, or smash a garlic clove into the potatoes for extra flavor.

9. Transfer to a serving dish, sprinkle 2 tablespoons chopped fresh parsley if using, and finish with flaky sea salt for crunch and a last bright pop of flavor.

10. Serve immediately while hot and crispy. Leftovers re-crisp great in a hot skillet or oven for 10 minutes.

Duck Fat Potatoes Recipe Substitutions and Variations

• Duck fat: use goose fat for a similar rich flavor, or rendered bacon fat for a smoky punch, or good quality olive oil if you want something lighter.
• Yukon Gold or russet potatoes: try red potatoes for creamier, waxier bites, fingerlings for a fancier look, or sweet potatoes if you like a slightly sweet, different texture.
• Fresh thyme or rosemary: swap with 1 teaspoon dried oregano, a few sprigs of fresh sage, or 1 teaspoon herbes de Provence for a more floral mix.
• Garlic cloves: use 1 teaspoon garlic powder in a pinch, 2 teaspoons roasted garlic paste for deeper sweetness, or skip and finish with a sprinkle of garlic salt.

Pro Tips

1) Dont overboil — aim for edges just tender, centers still firm. If they start falling apart youre too far. Parboil, drain, and let steam off a minute so they dry a bit before roughing up.

2) Roughing them in the pot is everything. Shake or tumble for 30–60 seconds so the outsides get starchy and ragged. Those little nooks are where the crust forms, so dont skip it.

3) Give each piece breathing room on the pan. Crowded potatoes steam not roast. Use two pans if needed and rotate pans front to back halfway through so everything browns evenly.

4) Use whole garlic cloves and herbs in the pan for flavor, but remove or smash a clove at the end if you want a mellow garlic hit. Fresh herbs in the last 10 minutes add brightness without burning.

5) Finish with flaky sea salt right before serving and re-crisp leftovers in a hot skillet or oven for 8–10 minutes. Cold potatoes straight from the fridge need more heat, so bring them close to room temp if you can for fastest re-crisping.
