Troubleshooting
Potatoes are soggy after roasting.
Make sure the duck fat is hot before adding potatoes and turn them every 20 minutes. Increase oven temperature to 230°C if needed.
Potatoes burn on the edges.
Check your oven's true temperature with an oven thermometer and reduce heat to 200°C. Remove any pieces that are browning too quickly.
Flour coating clumps.
Toss the potatoes gently in a large bowl with the flour before placing them on the tray; shake off excess flour.
Storage
Refrigerator: Store in an airtight container for up to 3 days; reheat in a hot oven to regain crispness.
Freezer: Not recommended – texture becomes soggy after freezing.
Room temperature: Can sit out for up to 2 hours; keep covered.
Make-Ahead Tips
- Parboil the potatoes and store them dry in the fridge for up to 24 hours before roasting.
- Flour coating can be applied ahead of time; keep coated potatoes covered in the fridge.

Common errors include adding potatoes to cold fat, skipping the flour coating, not turning the potatoes regularly, and using waxy potatoes that retain moisture. Each mistake reduces crispness and can lead to soggy potatoes.
Why does this duck fat rose potato recipe use baking soda instead of regular salt in the boiling water?
Baking soda raises the water’s pH, weakening the potato’s outer cell walls so they break down slightly during parboiling. This creates a rougher surface that crisps faster in the hot duck fat, whereas salt would only season the interior.
