Rinse, dry, and cut acorn in half. See my method in the post to easily cut the acorn squash.
Remove the seeds. Cut the squash into desired pieces or slices. Place the pieces in a bowl.
Pour the melted butter over the squash, then add the honey, and salt. Mix well to combine. Then place the squash pieces into the air fryer basket, reserving the honey butter mixture for later use if desired.
Roast on 400 degrees for 15 minutes. Base with the remaining honey butter mixture if necessary in between cooking. Serve warm and enjoy.
