Begin by slicing the acorn squash in half and remove the seeds. Cut each half into wedges to maximize grill contact and enhance caramelization.

Heat your grill to a high temperature, around 400°F, ensuring the grates are clean and well-oiled.

In a small bowl, combine melted butter and maple syrup to create a glaze. Generously brush this mixture onto each acorn squash wedge, seasoning with salt and pepper.

Place the seasoned squash wedges directly over the heat on the grill. Grill them for about 5-7 minutes, turning halfway through until they develop a nice char.

After achieving a good char, transfer the wedges to a cooler part of the grill. Lower the heat slightly and cover the grill. Cook for an additional 20-25 minutes until tender.

Once the squash is fork-tender, carefully remove it from the grill and drizzle any remaining maple butter glaze over the wedges.
