Fluffy, crispy-skin baked sweet potato made fast in the air fryer. Clear cooking times by size, simple ingredients, and reliable doneness cues. Includes ideas for sweet potato hash and air fryer sweet potato fries for easy weeknight variations.
– 2–4 medium sweet potatoes (9–12 oz each)
– 1–2 tbsp olive oil
– 1 tsp kosher salt
– 1/2 tsp black pepper
– Optional: 1/2 tsp cinnamon or 1/2 tsp smoked paprika
– For serving: butter or Greek yogurt, chopped chives, flaky salt
1. Scrub sweet potatoes and pat completely dry. Pierce each 6–8 times with a fork.
2. Rub lightly with olive oil; season skins with kosher salt and black pepper. Add cinnamon or smoked paprika if using.
3. Preheat air fryer to 390°F (200°C). Arrange potatoes in a single layer with space between them.
4. Air fry 35–45 minutes for medium potatoes, turning once halfway. Start checking at 35 minutes.
5. Doneness cues: skin feels crisp, a skewer slides in with little resistance, and center temp is near 205°F.
6. Rest 5 minutes. Split, fluff with a fork, and top with butter or Greek yogurt and chives. Season to taste.
7. For fries or hash with leftovers: cut, season, and air fry following the notes timings.

– Large (13–16 oz): 45–55 min at 390°F; reduce to 370°F if browning fast
Leftover spin-offs:
– Sweet Potato Hash (air fryer): 8–12 min at 400°F, shake once, add onions/peppers
– Sweet Potato Fries (air fryer): 12–18 min at 380–400°F, shake twice
Storage & Reheat:

Pro tip: Dry skins thoroughly; moisture inhibits crisping.
