Preheat oven to 400°.
Toss squash cubes with oil and salt. Place on a baking sheet in a single layer.
Bake for 25–30 minutes, stirring occasionally, until squash is soft and lightly browned. Remove from oven, add cranberries and let cool. Once cool, place squash into a baking dish for reheating the next day.
To reheat, preheat oven to 425°. Mix seeds together in a medium bowl. Sprinkle the seed mix evenly over the squash. Drizzle dish with ¼ cup maple syrup or to taste. Bake for 20 minutes, or until seeds are toasted.
