Bake squash for 20 minutes or until soft and lightly browned. Do not overcook. Squash should be bite-tender, not mushy.
To prepare crostini, spread approximately ½ tablespoon of ricotta on each prepared bread slice. Arrange roasted squash cubes, pomegranate arils, and peitas on crostini. Drizzle with pomegranate molasses.
¾ cup ricotta cheese, 4 tablespoons pomegranate seeds (arils), 2 tablespoons shelled pumpkin seeds (pepitas), pomegranate molasses, for serving
Serve immediately.
Notes
Crostini: You can easily make your own crostini (3 ways) with a fresh baguette. This can be done ahead if you want. Crostini can also be purchased.
Variations: Use honey, hot honey, or balsamic reduction instead of pomegranate molasses, if desired. Other types of spreadable cheese can be used instead of ricotta. Substitute different fresh herbs for the sage.
Make ahead: Crostini can be made a couple of days ahead, cooled thoroughly, and stored in an airtight container. Squash can be prepped and cut up to 3 days in advance; refrigerate. Squash can be roasted up to one day in advance; cool completely and store in refrigerator.
