Ingredients
Use the listed quantities. Spoon measurements are standard measuring spoons.
Method
- Scrub or peel the sweet potato. Cut into approximately 1.5 cm cubes, keeping the size as even as possible. Pat dry.
- Toss cubes with neutral oil, salt, and ground ginger. Preheat the air fryer to 190°C / 375°F if recommended.
- Spread in one layer with room for air to move. Cook for 14–20 minutes, shaking the basket after 7 minutes.
- Test one of the largest cubes with a fork. It should be tender through the center. Continue in 2-minute intervals if needed, watching the edges.
- Transfer to a bowl and toss with soy sauce, sesame oil, and sesame seeds. Serve warm.
Equipment that helps
A basket air fryer, sharp knife, and mixing bowl.
Even cubes and a loose layer matter more than presets. The Ninja AF141 5-quart air fryer Sponsored supports this recipe’s 375°F setting and has a removable crisper plate. Split the batch if the cubes overlap; test a large cube with a fork before serving.
Cooking notes & substitutions
Small, even cubes give you a tender middle without a long cooking time. Sweet potatoes brown naturally, so there is no need to add sugar before air frying. Use them in a rice bowl with edamame or serve beside greens.
Different sweet potatoes
Dense Japanese sweet potatoes may need longer and will have a drier texture than orange-fleshed varieties.
More than two servings
Use batches. A deep pile cooks unevenly, even if the appliance’s advertised capacity sounds large enough.
Avoid a sticky basket
Add sweet sauces after cooking. Sugar in a glaze can burn before the potato center becomes tender.
Questions before you cook
Should I soak the cubes?
This method does not require soaking. Dry surfaces and enough space in the basket matter more for the intended browned edges.
Leftovers & food safety
Refrigerate leftovers promptly in shallow containers. Do not leave cooked food at room temperature for more than 2 hours, or 1 hour above 90°F / 32°C. Reheat leftovers to 165°F / 74°C. Follow package instructions and use a thermometer where appropriate. USDA leftover guidance.
