Air Fryer Sweet Potato Fries Time & Temp Guide

By Airfryer Conversion Chart Culinary Team • Reviewed on 2025-08-16

Air fryer sweet potato fries cook quickly and get crisp with far less oil than deep frying.

In our testing, fresh-cut wedges were ideal at 390°F for 12–15 minutes, while packaged frozen fries cooked through in 14–16 minutes at 400°F. Shoestring-style fries were crisp at 10–12 minutes.

Shake the basket halfway for even browning, and don’t overcrowd.

Pro tip: Pair with a dipping sauce like chipotle mayo or garlic aioli for maximum flavor.
