Key Ingredients for Air Fryer Japanese Sweet Potato:
- 4 medium Japanese sweet potatoes (about 6-8 oz each)
- 1 tablespoon olive oil or avocado oil
- 1 teaspoon sea salt
- Optional toppings: butter, cinnamon, honey, or fresh herbs
Step-by-Step Instructions:
- Prepare the Sweet Potatoes: Wash and scrub the Japanese sweet potatoes thoroughly under cold running water. Pat them completely dry with paper towels. Using a fork, pierce each sweet potato 8-10 times all over to prevent bursting during cooking.
- Season the Potatoes: Rub each sweet potato with olive oil, ensuring all surfaces are coated. Sprinkle with sea salt and gently rub it into the skin for extra flavor and crispiness.
- Preheat the Air Fryer: Set your air fryer to 400°F (200°C) and preheat for 3-5 minutes. This ensures even cooking from the start.
- Cook the Sweet Potatoes: Place the sweet potatoes in the air fryer basket, leaving space between each one for proper air circulation. Cook for 25-30 minutes, depending on size.
- Check for Doneness: After 25 minutes, gently squeeze the sweet potatoes (they should give slightly) or insert a fork – it should slide in easily. If they need more time, cook for an additional 5 minutes.
- Rest and Serve: Remove from the air fryer and let rest for 2-3 minutes. Cut open immediately while hot and fluff the flesh with a fork. Add your favorite toppings and serve warm.

Top Tips for Perfecting Air Fryer Japanese Sweet Potato:
Choose the Right Size
Select sweet potatoes that are similar in size (6-8 oz each) for even cooking. Avoid overly large potatoes as they may not cook evenly in the air fryer.
Don’t Skip the Piercing
Always pierce the sweet potatoes thoroughly with a fork before cooking. This prevents them from bursting due to steam buildup during the cooking process.
Adjust Cooking Time
Smaller sweet potatoes (4-6 oz) may only need 20-25 minutes, while larger ones (8-10 oz) might require 30-35 minutes. Check for doneness by gently squeezing – they should yield to pressure when ready.
Avoid Overcrowding
Don’t overcrowd the air fryer basket. Cook in batches if necessary to ensure proper air circulation around each sweet potato.
Storing and Reheating Tips:
Storage: Store cooked Japanese sweet potatoes in the refrigerator for up to 4 days in an airtight container. Let them cool completely before storing to prevent condensation.
Freezing: For longer storage, wrap cooled sweet potatoes individually in plastic wrap and freeze for up to 3 months. Thaw in the refrigerator overnight before reheating.
Reheating: To reheat, place in the air fryer at 350°F for 3-5 minutes, or microwave for 1-2 minutes until warmed through. For best results, cut open and add a pat of butter before reheating to restore moisture.
