Ingredients For Japanese Roasted Potato Recipe
Potatoes: The base of the dish, providing a starchy and satisfying texture.

Technique Tip for This Recipe
When roasting potatoes, ensure they are cut into evenly sized wedges to promote uniform cooking. To achieve maximum crispiness, avoid overcrowding the baking sheet; this allows hot air to circulate around each piece. For an extra layer of flavor, consider adding a pinch of garlic powder or paprika to the olive oil mixture before tossing the potatoes.

How to Store or Freeze This Recipe
- Allow the potatoes to cool completely before storing. This prevents condensation, which can make them soggy.
- Transfer the cooled potato wedges to an airtight container. For best results, use a container that fits the potatoes snugly to minimize air exposure.
- Store the container in the refrigerator. The roasted potatoes will keep well for up to 3-4 days.
- To reheat, preheat your oven to 375°F (190°C). Spread the potato wedges on a baking sheet and bake for 10-15 minutes, or until heated through and crispy.
- For freezing, place the cooled potato wedges on a baking sheet in a single layer. Freeze for about 1-2 hours, or until they are solid. This prevents them from sticking together.
- Once frozen, transfer the potato wedges to a freezer-safe bag or container. Label with the date and store in the freezer for up to 2 months.
- To reheat from frozen, preheat your oven to 400°F (200°C). Spread the frozen potato wedges on a baking sheet and bake for 20-25 minutes, or until golden and crispy.
- For a quicker reheating option, use an air fryer. Preheat the air fryer to 375°F (190°C) and cook the frozen potato wedges for 10-12 minutes, shaking the basket halfway through.
How to Reheat Leftovers
Oven Method: Preheat your oven to 375°F (190°C). Spread the leftover potato wedges on a baking sheet in a single layer. Cover them with aluminum foil to prevent them from drying out. Heat for about 10-15 minutes, then remove the foil and bake for an additional 5 minutes to regain their crispiness.
Stovetop Method: Heat a non-stick skillet over medium heat. Add a small amount of olive oil or sesame oil to the pan. Place the potato wedges in the skillet and cook for 5-7 minutes, turning occasionally, until they are heated through and crispy.
Microwave Method: Place the potato wedges on a microwave-safe plate. Cover them with a damp paper towel to keep them moist. Microwave on high for 1-2 minutes, checking halfway through to ensure they are heated evenly. Note that this method may not retain the original crispiness.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Arrange the potato wedges in a single layer in the air fryer basket. Heat for 3-5 minutes, shaking the basket halfway through to ensure even reheating. This method helps to restore their crispy texture.
Toaster Oven Method: Preheat your toaster oven to 375°F (190°C). Place the potato wedges on the toaster oven tray in a single layer. Heat for 10-12 minutes, turning them halfway through to ensure they are evenly reheated and crispy.
