Roasted Acorn Squash with Cinnamon Butter

Preheat oven to 450 degrees. On a large rimmed baking sheet, toss squash with oil; season with salt and pepper. Arrange on sheet, cut side down, and roast until easily pierced with a paring knife, 35 to 45 minutes.

In a small saucepan, melt butter over medium heat, stirring, until golden brown, 4 to 6 minutes. Immediately pour into a small bowl; stir in cinnamon. Place squash on a serving platter; top with cinnamon butter.
