Halved acorn squash roasts in 22 minutes at 380 °F (193 °C) without flipping. The cut-side-up presentation lets the butter pool in the cavity and baste the flesh while the cut face caramelises into a sweet, nutty crust.

How to tell it’s done

Cut sides are deeply caramelised; flesh near the edges is golden-brown; a fork pierces the flesh with no resistance.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. Brush the cut faces with melted butter or olive oil. A spoonful of butter in each cavity melts and bastes the flesh.

2. 2

   Season

   Season with salt, black pepper, brown sugar in the cavity, cinnamon, nutmeg.

3. 3

   Load

   Arrange 1 acorn squash, halved through the stem and seeded (serves 2) for best convection airflow.

4. 4

   Cook

   Set the air fryer to 380 °F (193 °C) and cook for 22 minutes total.

5. 5

   Check & rest

   Check the visual doneness cue and serve immediately for best texture.

6. 6

   Store

   Refrigerate up to 4 days. Reheat at 380 °F for 5 minutes.

Watch out for

• !Cut-side up only — placing cut-side down traps steam against the flesh and stops the caramelisation.
• !Score the cut face in a crosshatch pattern about ¼ inch deep before cooking. The cuts let seasoning penetrate and the surface caramelise more evenly.
• !Halve through the stem (top to bottom), not equator-wise — the stem half steadies the squash so it sits flat in the basket.

FAQ about acorn squash in an air fryer

What temperature should I cook acorn squash at in an air fryer?

Cook acorn squash at 380 °F (193 °C). The convection air at this temperature cooks the centre evenly while still browning the surface.

How long does acorn squash take in an air fryer?

Acorn squash takes 22 minutes at 380 °F (193 °C) with no flipping needed. Cook in a single layer for the air to circulate.

Do you need to flip acorn squash in an air fryer?

No — acorn squash cooks evenly without flipping. The convection air reaches all sides simultaneously. Flipping is only needed for dense or thick foods where one side sits against the basket grate; this food does not benefit from it.

Do you need to preheat the air fryer for acorn squash?

Preheating is optional for acorn squash — most modern air fryers reach temperature in under 2 minutes and the food's total cook time already accounts for the ramp-up. If you do preheat, reduce the total time by 1–2 minutes and check earlier than usual.
