In the hands of hungry commuters, the croissants, breads and cheesecakes from Zaro’s Family Bakery counters in Grand Central Terminal and Pennsylvania Station travel across the New York region and beyond.

But these treats all start off in the Bronx.

They are made from scratch day and night inside a 40,000-square-foot brick factory in the Port Morris neighborhood that anchors a family-run business founded in the Bronx in 1927 by Joseph Zaro, a Jewish immigrant from Poland, and carried on by his sons, grandsons and great-grandsons. Today, Zaro’s has eight bakeries in Midtown Manhattan and in Newark, and also sells its baked goods through FreshDirect, an online grocer, and at stores including Balducci’s and Kings Food Markets.

Now in a nod to its roots, Zaro’s is expanding with two new bakeries in the Bronx. The first will open in October in the Parkchester neighborhood, just two doors from where its last bakery in the borough closed in 2015 after losing its lease. A second bakery will follow early next year at the Port Morris factory.

Bronx residents are already lining up to welcome back the bakery. “I’m really excited because it was part of us,” said Marie Gianno, 62, a preschool teacher in Parkchester who has missed the challah, rye and pumpernickel breads. “Where are you going to meet? We always chose Zaro’s. It was part of the neighborhood.”
