Arrange the pear halves on a parchment-lined baking sheet.
Drizzle the pears with the olive oil and white balsamic.
Season with a pinch of sea salt and freshly cracked black pepper.
Roast for 20–25 minutes, until the pears are tender and lightly caramelized.
Remove from the oven and immediately top with the crumbled gorgonzola and toasted walnuts.
(Optional) Move the pears to the middle rack and broil for 1–2 minutes, just until the cheese softens and the nuts deepen in color. Watch closely to avoid burning.
