What are Japanese sweet potatoes?
Japanese sweet potatoes, also known as “Satsumaimo,” are a type of sweet potato that is native to Japan. They are characterized by their purple skin and pale yellow flesh, which has a sweet, nutty flavor and a creamy texture when cooked. Unlike regular sweet potatoes, they have a firmer texture and a more subtle sweetness, making them a favored ingredient in various Japanese dishes.
In addition to their unique flavor, Japanese sweet potatoes are rich in nutrients. They are an excellent source of vitamins A and C, fiber, and antioxidants.

How do you prepare Japanese sweet potatoes for air frying?
Preparing Japanese sweet potatoes for air frying is simple and straightforward. Start by washing the sweet potatoes thoroughly to remove any dirt or impurities. If you prefer, you can peel them, but keeping the skin on adds additional nutrients and a delightful texture. Cut the sweet potatoes into uniform pieces – either rounds or wedges – to ensure even cooking and better air circulation.
After cutting, it’s important to season the pieces. Toss them with a small amount of oil to help them crisp up in the air fryer. You can also add salt, pepper, garlic powder, or any seasoning of your choice for enhanced flavor. Once seasoned, place them in the air fryer basket, ensuring they are not overcrowded, allowing for optimal air circulation and even cooking.
What cooking time and temperature should I use for air-frying Japanese sweet potatoes?
For optimal results, preheat your air fryer to 375°F (190°C). The cooking time usually ranges from 15 to 25 minutes, depending on the size of your sweet potato pieces. It’s advisable to give them a stir or flip halfway through the cooking process to ensure even browning and crispiness.
Keep an eye on the sweet potatoes as they cook, particularly towards the end of the cooking time. If you prefer a softer texture, you might take them out sooner, while a longer cooking time will yield a firmer, crispier exterior. Always test for doneness by piercing them with a fork; they should be tender inside yet still hold their shape.
