How long to cook butternut squash in an air fryer?
Cook butternut squash in an air fryer at 200°C / 400°F for about 12–16 minutes for ½-inch cubes, or 15–20 minutes for 1-inch cubes. Halved butternut squash takes longer, usually 24–35 minutes at 190–200°C / 375–400°F.
Air fryer butternut squash is fastest when cut into even cubes, but halves also work if your basket is large enough. Use high heat for cubes and slightly gentler heat for halves, then cook until the thickest part is fork-tender.
Time & temperature chart
| Size / cut | Temp | Time | Tip |
|---|---|---|---|
| Fresh ½-inch / 1.25 cm cubes | 200°C | 12–16 min | Shake or toss halfway for even browning. |
| Fresh 1-inch / 2.5 cm cubes | 200°C | 15–20 min | Check the largest pieces for fork tenderness. |
| Fresh cubes, crowded basket or larger batch | 200°C | 20–25 min | Best cooked in batches; crowded squash steams before it brow |
| Halved butternut squash, cut side down | 190°C | 24–35 min | Time varies with squash size and basket clearance. |
| Frozen butternut squash cubes, no thaw | 200°C | 15–20 min | Cook from frozen in a single layer; shake halfway. |
Times are a guide — air fryers vary by 10–20%. Always cook to the safe internal temperature, not just the timer.
How to air fry butternut squash
- 1
Preheat the air fryer to 200°C for cubes, or 190°C for halved butternut squash.
- 2
For cubes, peel and seed the squash, then cut it as evenly as possible. Smaller ½-inch cubes cook faster than 1-inch cubes.
- 3
Spread the butternut squash in a single layer in the basket. A little overlap is fine, but avoid a tightly packed pile.
- 4
Air fry using the timing table, shaking or tossing cubes halfway through. For halves, check near the center of the thick neck end.
- 5
Cook until the squash is fork-tender with lightly browned edges. Add 2–5 extra minutes if the largest pieces are still firm.
Pro tips
- Cut pieces evenly so they finish at the same time; mixed sizes can leave small pieces browned while larger ones stay firm.
- For the quickest result, use ½-inch cubes at 200°C. For softer centers and less browning, use slightly larger cubes or reduce the temperature to 190°C.
- Do not thaw frozen butternut squash cubes before air frying; cook them straight from frozen for better texture.
- If the basket is crowded, cook in two batches or expect to add several minutes and shake more than once.
- Halves need more time than cubes because the thick neck of the squash takes longer to soften.
