Preheat oven to 400°. Line a baking sheet with parchment paper or a silicon baking mat.
Cut off both ends of the acorn squash and discard. Then, cut squash in half, lengthwise and scoop out and discard seeds from the center.
Lay each half of the acorn squash flat side down, and slice into 1 inch pieces, so they look like little flowers. Arrange on your baking sheet.
In a separate bowl, mix together the remainder of the ingredients.
With a basting brush or a spoon, coat each side of your acorn squash slices with the olive oil mixture.
Place into the oven and bake for 40-45 minutes, or until fork tender and caramelized. No need to flip during cooking.
Serve alongside your favorite fall dish and enjoy!
