Preheat oven to 250°. Scatter torn sourdough in a single layer on a baking sheet. Check occasionally & cook about 1 hour or until dried out.
Grease a 13x9x2" baking dish with unsalted butter and set aside.
Melt remaining butter in a large skillet over medium-high heat; add onions, shallots, celery & fennel & stir often till beginning to brown. About 10 minutes.
Deglaze pan with wine & scrape the bottom of the pan to release any browned bits. Add in herbs & seasonings. Bring to a boil & cook until wine evaporates, about 3 minutes.
Allow several minutes to cool in pan (or risk cooking eggs)
In a separate bowl, whisk eggs & broth. Pour mixture over bread & fold combining, thoroughly. Once vegetables are completely cooled, mix in & add all of stuffing mixture to a 13 x 9 x2 baking dish.
Cover with foil & bake at 350 for 35-40 minutes or until internal temperature hits 160. If making in advance, pause here.
Increase oven to 425 & continue baking uncovered till golden brown for about another 20 minutes.
NOTE : Can be baked (but not browned) in advance.
NOTE: Thicker slices of bread work better than thinner. STALE BREAD does NOT absorb liquid as well as DRIED BREAD.
