This sourdough focaccia stuffing with sage butter is the ultimate holiday side dish. Tangy sourdough, nutty sage butter, and sweet caramelized onions create a rich, savory stuffing that will steal the show at any gathering.
For best texture, use stale or dried bread. Fresh bread will turn gluey. The sage butter should be slightly browned but not burnt. Assemble the dish a day ahead for easier hosting. Add 10 extra minutes to covered baking time if baking from cold. Leftovers can be stored in the refrigerator for up to 4 days or frozen for up to 3 months.
