Preheat the oven to 425 degrees. Prepare 2 baking sheets with nonstick foil, if desired.

In a large bowl, combine the chopped butternut squash with the olive oil and bourbon.

Using a slotted spoon, place the coated squash evenly on 2 baking sheets. Discard any leftover liquid.

Combine the brown sugar, cinnamon, and salt and sprinkle over the cubed squash. Stir lightly to make sure all the pieces are coated.

Bake at 425 degrees for 15 minutes and then switch the baking sheets on the oven racks and bake for another 15 minutes or until the squash is fork tender.
