Step-by-step

1
Prep Sweet Potatoes for the Air Fryer
Choose your cut: fries = peel and slice into 1/4-inch planks, then cut into 1/4-inch sticks. Cubes = peel and cut into 1/2–1-inch chunks. Whole = pierce all over with a fork, no foil. For crispier fries, soak in hot tap water 10 min, drain, then pat completely dry — moisture kills crispiness. Toss fries or cubes with a light coat of oil, salt, garlic powder, paprika, and black pepper. Whole potatoes need no oil. Cook in a single layer; batch if needed.

Air Fryer Sweet Potatoes: Temps & Times by Cut
Fries (1/4-inch): 350–380°F, single layer. Cook 8 min, shake, cook 5 more min (12–13 min total). Batch cooking: toss done batch with remaining oil/seasoning, return all to basket for a final 2–3 min together.

Cubes (1/2–1 inch): Preheat to 350–400°F, lightly grease basket. Single layer. Shake every 5 min. 1/2-inch at 400°F = 10–12 min. 1-inch at 350°F = 20–25 min.

Whole: No preheat. Pierce with fork, no foil. 370°F for 35–45 min. ~6 oz potato = 35–40 min. Unwrapped skin crisps while interior steams fluffy.

All cuts: No stacking or overlapping — blocked surfaces steam instead of crisp. Cook in batches if needed.

Doneness Cues and Serving
Fries: edges lightly browned, centers fork-tender. They crisp more as they cool — pull when golden, don't over-fry. Cubes: fork-tender throughout, caramelized with browning on at least one or two sides. Whole potatoes: fork or skewer slides in with zero resistance; skin slightly crisp, flesh soft when gently squeezed (use an oven mitt). If any resistance remains, return in 5-minute increments. Avoid: skipping the drying step (causes steaming), overcrowding (causes sogginess), too much oil (causes greasy uneven browning). Serve fries and cubes immediately. Whole potatoes can rest 2–3 minutes before topping.
