Serves: 4–6
✅ Ingredients
-
2 kg (4½ lb) potatoes (Maris Piper, Yukon Gold, or Russet)

½ tsp baking soda (secret for crispiness!)
-
4–5 tbsp duck fat, goose fat, or olive oil

1 tsp salt (plus more to finish)

Bring to a boil and cook 8–10 minutes until edges are soft.
-
Drain well and let steam dry for 2 minutes.
2️⃣ Rough Them Up
-
Shake potatoes in the pot until edges are fluffy and roughed up
(This creates maximum crunch later)
3️⃣ Heat the Fat
-
Preheat oven to 220°C / 425°F.
-
Add fat/oil to a roasting tray and heat in oven for 5–7 minutes until sizzling hot.
4️⃣ Roast
-
Carefully add potatoes to hot fat.
-
Turn to coat, sprinkle with salt, pepper, garlic powder.
-
Roast 25 minutes, flip, then roast another 20–30 minutes until deep golden and crisp.
5️⃣ Finish
-
Add herbs in the last 10 minutes.
-
Sprinkle with flaky salt and serve immediately.
😍 Pro Tips

Don’t overcrowd the tray—space = crispiness

Turn only once for best crunch
