For the best texture, cut the squash into uniform cubes so they roast evenly and develop caramelized edges. If your baguette is very fresh, toasting a bit longer helps keep the topping from making it soggy. Browning the butter until it smells nutty enhances the sage flavor—pull it off the heat as soon as the milk solids turn light amber to avoid burning. You can roast the squash a day ahead and rewarm it in the sage butter just before assembling. Add crispy prosciutto, goat cheese, or toasted pepitas for variations, and adjust heat by increasing or omitting red pepper flakes.
