Preheat the oven to 400° F. Line a baking sheet with parchment paper.
Toss the pear quarters with the thyme, oil, and salt. Spread on the prepared baking sheet and roast for approximately 30-35 minutes, or until the pears are tender and deeply bronzed.
Transfer to a food processor or blender and puree to desired consistency, adding water if necessary. Enjoy!
