The Best Ways to Reheat Roasted Baby Potatoes or Fries

1. Reheat Baby Potatoes in the Air Fryer (Best Method)

If you have an air fryer, it’s hands-down the best way to reheat roasted potatoes or baby potato fries. It brings back the crispiness without drying them out.

Steps:

1. Preheat your air fryer to 375°F.
2. Place leftover baby potatoes or fries in a single layer.
3. Heat for 4–6 minutes, shaking the basket halfway through.
4. Serve immediately—crispy and delicious!

👉 Why it works: The air fryer circulates hot air around the potatoes, recreating that fresh-from-the-oven texture.

 2. Reheat Roasted Potatoes in the Oven

Don’t have an air fryer? The oven is your next best bet.

Steps:

1. Preheat oven to 400°F.
2. Spread your baby potatoes or fries on a baking sheet in a single layer.
3. Spritz lightly with oil or cooking spray.
4. Reheat for 10–12 minutes, flipping halfway through.

👉 Pro tip: Use a wire rack on your baking sheet to allow air to circulate underneath and prevent sogginess.

 3. Reheat on the Stovetop for Crispy Skillet Potatoes

Want your potatoes to have a pan-fried finish? Try this stovetop method.

Steps:

1. Heat a nonstick or cast iron skillet over medium heat.
2. Add a small amount of oil or butter.
3. Toss in your baby potatoes or fries.
4. Cook for 5–7 minutes, turning occasionally until crispy.

👉 Great for: Breakfast potatoes or brunch leftovers.

4. Can You Reheat Baby Potatoes in the Microwave?

You can, but be warned—it’s the least crispy method. Microwaving is fast, but it tends to soften potatoes and fries rather than crisp them.

How to do it:

1. Place potatoes on a microwave-safe plate lined with a paper towel.
2. Microwave in 30-second bursts until warmed through.
3. For a slightly crispier result, transfer to a hot pan or air fryer afterward for a quick finish.
