You’ll Need
1kg Maris Piper potatoes, peeled and cut into chunky roast potato pieces
2 tbsp goose fat, beef dripping, or vegetable oil
1 tsp sea salt
½ tsp black pepper
1 tsp garlic powder
1 tsp dried rosemary
Optional But Dangerous
Extra sea salt
Fresh rosemary
Gravy for dunking
Method
Preheat your air fryer to 200°C.
Place the potatoes into a saucepan of cold salted water.
Bring to the boil and simmer for 8–10 minutes until the edges soften slightly.
Drain thoroughly.
Return the potatoes to the empty pan and shake aggressively.
You want rough, fluffy edges. That's where the crunch comes from.
Add the goose fat, salt, pepper, garlic powder, and rosemary.
Toss carefully until every potato is coated.
Place the potatoes into the air fryer basket in a single layer.
Do not overcrowd them.
Work in batches if necessary.
Air fry at 200°C for 22–28 minutes, shaking every 7–8 minutes, until deeply golden, crispy, and beautifully crunchy all over.
For maximum Christmas dinner glory, give them a final 2-minute blast at 205°C.
Serve immediately while still crackling hot.
