The duck fat is non-negotiable here—render your own or order online from D’Artagnan or Fatworks. Look for pure, unadulterated fat without additives. Yukon Golds are ideal for their buttery texture and moderate starch content (they crisp up without turning to mush). Whole Foods or a good butcher shop usually carries duck fat if you don’t want to render it yourself.
No duck fat? Beef tallow is the closest substitute, though the flavor won’t be as rich. Avocado oil or ghee work in a pinch but lack that signature depth. For the herbs, dried at one-third the amount is fine, but fresh really shines. The vinegar soak is key—don’t skip it (removes excess starch for maximum crisp).
These are best eaten fresh, but leftovers reheat well in a 400°F oven for 10-15 minutes. Store uncooked duck fat in the fridge for up to 3 months—it solidifies but melts easily when heated. Potatoes don’t hold well, so fry what you need.

Step-by-Step Instructions for Crispy Duck Fat Potatoes
This double-fry method guarantees perfectly golden, ultra-crispy potatoes with a fluffy interior.
Step 1: Prep and Parboil the Yukon Gold Potatoes
Peel and cut the 2 lb Yukon Gold Potatoes into uniform 1½-inch chunks. Place them in a bowl of cold water with the 1 tbsp White Vinegar and let soak for 15 minutes to remove excess starch, which ensures maximum crispiness.
Drain and rinse the potatoes, then transfer to a large pot. Cover with cold water, add the 0.25 tsp Baking Soda, and bring to a boil. Reduce heat and simmer for 8-10 minutes until the potatoes are tender but not falling apart. Drain thoroughly and pat completely dry with a kitchen towel.
Step 2: First Fry in Duck Fat for Foundation
In a heavy-bottomed pot or Dutch oven, heat the 1 cup Duck Fat over medium-high heat to 325°F. Working in batches to avoid crowding, carefully add the parboiled potatoes. Fry for 10-12 minutes, turning occasionally, until they develop a pale golden crust but aren’t fully browned.
Using a slotted spoon, transfer the potatoes to a wire rack set over a baking sheet. While still hot, sprinkle with 1 tsp Freshly Ground Black Pepper and the 0.5 tsp Smoked Paprika. This first fry creates the structural foundation for that coveted crunch while cooking the potatoes through.
Step 3: Infuse Oil with Aromatics
In a small saucepan, combine the 2 tbsp Olive Oil with the 4 cloves Garlic Cloves, 2 tbsp Fresh Rosemary, and 1 tbsp Fresh Thyme. Heat over low heat for 3-5 minutes until the garlic is lightly golden and the herbs release their fragrance.
Strain the oil through a fine-mesh sieve to remove the solids, reserving the infused oil. This aromatic oil will add depth of flavor during the final crisping stage. Discard the solids or save them for another use.
Step 4: Second Fry for Ultimate Crispiness
Increase the heat of the duck fat to 375°F. Return the potatoes to the hot fat in batches, frying for 3-4 minutes until they’re deep golden brown and irresistibly crispy. The higher temperature ensures rapid browning without overcooking the interior.
Transfer the potatoes to a clean wire rack. While still hot, drizzle with the reserved infused olive oil and sprinkle with the remaining 2 tsp Kosher Salt. For extra shine and richness, toss with the 2 tbsp Unsalted Butter while still warm.
Pro Tips For Making Crispy Duck Fat Potatoes
- Parboil First: I learned this the hard way—boil the Yukon Golds in salted water for 8-10 minutes before roasting. It softens the centers so they crisp up perfectly in the duck fat without drying out.
- Hot Pan, Hot Fat: Crank the oven to 425°F and make sure the duck fat is smoking hot in the pan before adding the potatoes. Sounds obvious, but cold fat just soaks in instead of creating that glass-like crust.
- Dry Them Well: After parboiling, let the potatoes air-dry on a rack for 5 minutes, then pat them completely dry. Any moisture left on the surface steams instead of fries in that expensive duck fat.
- Crush for Crisp: Skip the knife—press each parboiled potato gently with a glass or fork before roasting. The rough edges catch more fat and turn extra crispy, especially with the rosemary clinging to all those nooks.
Creative Variations of This Recipe
Herb-Crusted Variation
After the second fry, toss the hot potatoes with 2 tbsp finely grated Parmesan and an extra 1 tbsp chopped rosemary. The cheese melts instantly, creating a crispy, savory crust. I love this for Sunday roasts with lamb or beef. 🌿
Spicy Cajun Twist
Swap the smoked paprika for 1 tbsp Cajun seasoning (I use Tony Chachere’s). Add ½ tsp cayenne pepper to the first fry for heat that builds with each bite. Serve with remoulade for dipping.
Garlic-Lover’s Dream
Double the garlic in the infused oil and add 1 tsp garlic powder to the post-fry seasoning. For extra punch, sprinkle with 2 tbsp finely chopped chives while hot. This version disappears fastest at my dinner table.
Breakfast Hash Style
Cut potatoes into ½-inch cubes before boiling. After the second fry, mix with ½ cup diced cooked bacon and ¼ cup shredded cheddar. Broil for 2 minutes to melt the cheese. 💛
Mediterranean Flavor
Add 1 tsp dried oregano and ½ tsp lemon zest to the infused oil. After frying, finish with ¼ cup crumbled feta and a squeeze of fresh lemon. Bright, tangy, and irresistibly crisp.

Frequently Asked Questions
Can I substitute another fat if I don’t have duck fat?
Yes, but the flavor won’t be the same. Beef tallow is the closest alternative, while avocado oil or ghee work in a pinch. Duck fat’s richness is hard to replicate.
Why do I need to fry the potatoes twice?
The first fry at 325°F cooks the potatoes through, while the second at 375°F creates the crispy exterior. This two-step method ensures a fluffy interior and perfect crunch.
How do I store leftover duck fat?
Strain and store cooled duck fat in an airtight container in the fridge for up to 3 months. It solidifies but melts easily when reheated.
Can I make these potatoes ahead of time?
Best eaten fresh, but you can parboil and do the first fry up to 2 hours ahead. Reheat in a 400°F oven for 10-15 minutes to restore crispiness.
