How to cook Butternut Squash in an air fryer
- Uniform cubes matter more here than with softer vegetables — squash is dense and cooks unevenly otherwise.
- Toss generously in oil; squash is dry and will leather at the edges without it.
- A pinch of sugar or maple at the end caramelises well, but added early it burns.
Cooking Butternut Squash from frozen
From frozen, cook for 18–24 minutes at 400°F. Frozen cubes stay softer and will not caramelise as well.
