3-Step Execution Protocol

1
Preheat & Prep

Preheat air-fryer to 375°F (191°C). Place acorn squash (halved, roasted) (1 medium acorn squash (about 1.5 lbs), halved lengthwise, seeds scooped out, flesh scored in diamond pattern, brushed with melted butter and maple syrup) in a single layer with space between items for convection airflow. Spray lightly with high-smoke-point oil.

2
Cook

Cook for 20–25 mins. Do not flip; allow surface to develop undisturbed.

3
Check & Rest

Flesh is fork-tender to the skin with rich caramelized brown edges throughout the cavity. Rest for 2 minutes before serving.

Pro Tip: Score the flesh 1/2-inch deep in a criss-cross diamond pattern before air frying so the butter and spices seep deep into the squash as it roasts.
