Preheat the oven to 375 degrees. Line a baking sheet with parchment paper.
Using a sharp chef's knife, cut the ends off the acorn squash then slice into rings.
Cut the seeds and membrane out of each ring.
Place onto the prepared baking sheet.
Combine the softened butter with the honey, cinnamon, and salt; mix until well combined and creamy.
Brush just a little bit of cinnamon honey butter on the bottom of the rings then return to the baking sheet.
Brush more of the cinnamon honey butter on the top and insides of the rings; reserving some of the honey butter for later use.
Place the squash into the oven and roast for 20-25 minutes, or until tender.
Remove from the oven.
Place the remaining honey butter into the microwave for a few seconds until melted.
Drizzle the melted honey butter over the squash rings.
Serve immediately. Enjoy.
