Small potatoes (like baby or new potatoes) usually take about 15–20 minutes in a standard air fryer at 400 °F (200–205 °C), depending on size and how crispy you want them.

Typical cooking time & temp

For small potatoes (about 1–1.5 inches / 2.5–4 cm across):

  • Whole small potatoes (like baby potatoes):
    Air fry at 400 °F (200–205 °C) for 15–20 minutes, shaking or flipping halfway through.

They’re done when the outside is golden and crisp, and a fork slides in easily.

  • Halved or quartered small potatoes :
    Cook at 400 °F (200–205 °C) for 12–18 minutes, shaking once or twice.

Smaller pieces cook faster and get crispier.

How to adjust for your air fryer

Air fryers vary, so here’s how to fine‑tune:

  • Smaller potatoes (under 1 inch / 2.5 cm):
    Start checking at 12–14 minutes; they can be done in 12–16 minutes.
  • Larger small potatoes (closer to 2 inches / 5 cm):
    May need 18–25 minutes; add 2–3 minutes at a time if they’re still firm in the center.
  • Crowded basket :
    If the potatoes are piled up, they’ll steam instead of crisp; cook in a single layer and cook in batches if needed.

Simple step‑by‑step

  1. Prep
    • Wash small potatoes and cut them in half (or leave whole if very small).
 * Toss with oil (1–2 tbsp per pound), salt, pepper, and any spices (garlic powder, paprika, herbs).
  1. Air fry
    • Preheat air fryer to 400 °F (200–205 °C) for 3–5 minutes (optional but helps crispiness).
 * Spread potatoes in a single layer in the basket.

 * Cook for 15–20 minutes total, shaking or flipping halfway through.
  1. Check doneness
    • Pierce a potato with a fork; it should slide in easily and the center should be tender.
 * If not quite done, continue in 2–3 minute increments until perfect.

Tips for best results

  • Dry potatoes
    Pat them dry after washing so they crisp up better.
  • Don’t overcrowd
    A single layer with a little space between pieces gives the crispiest results.
  • Shake or flip
    Tossing halfway through ensures even browning and prevents sticking.
  • Extra crispy
    For extra crunch, spray or drizzle a little more oil after the first 10 minutes and keep cooking until golden.

Quick reference table

Potato size & prep| Temp| Time| Notes
---|---|---|---
Whole baby potatoes (1–1.5")| 400 °F (200–205 °C)| 15–20 min| Shake halfway; fork-tender when done
Halved small potatoes| 400 °F (200–205 °C)| 12–18 min| Smaller pieces cook faster
Quartered small potatoes| 400 °F (200–205 °C)| 10–16 min| Best for very crispy edges

If you tell me the exact size of your potatoes and your air fryer model (if known), it’s easy to give a more precise time.
