Reheat leftover roasted potatoes to crispy perfection using an oven or air fryer. Skip the microwave for best results.
Quick Answer
For the crispiest leftover roasted potatoes, reheat them in an oven at 400°F or an air fryer at 375°F. Avoid the microwave, which makes them soggy.
Why the Oven or Air Fryer Works Best
Reheating roasted potatoes in a microwave steams them, turning the crispy exterior soft and the interior mushy. An oven or air fryer uses dry heat to re-crisp the surface while warming the center evenly. This is especially important for larger batches from catering, where texture matters.
The key is to spread the potatoes in a single layer so hot air reaches all sides. Overcrowding traps steam and prevents crisping.
Steps for Crispy Reheated Roasted Potatoes
- Oven Method: Preheat oven to 400°F. Spread leftover roasted potatoes in a single layer on a baking sheet. Bake for 5-10 minutes, flipping halfway, until hot and crispy. Check at 5 minutes to avoid burning; smaller pieces crisp faster.
- Air Fryer Method: Preheat air fryer to 375°F. Place potatoes in a single layer in the basket (avoid stacking). Cook for 3-5 minutes, shaking halfway, until golden and crisp. Do not overcrowd the basket; work in batches if needed.
- Avoid the Microwave: Microwaving roasted potatoes makes them soft and soggy. If you must use it, microwave only to warm, then finish in a hot skillet with a little oil for 2 minutes per side. This two-step method is a compromise; oven or air fryer still yields better texture.
