Costco's Olive and Rosemary Sourdough Bread is a hearth-baked artisan loaf made in the warehouse bakery. The bread features a robust sourdough flavor developed through a slow fermentation process, with savory Kalamata or black olives and fragrant rosemary baked throughout. Each loaf is hand scored before baking, giving it a rustic appearance with a crisp, golden crust and a chewy, open crumb typical of traditional sourdough.

Weighing nearly two pounds, this large loaf is well suited for sharing, entertaining, or everyday use. It pairs naturally with olive oil and balsamic vinegar, cheese boards, soups, and hearty sandwiches. The combination of tangy sourdough, briny olives, and earthy rosemary makes it a flavorful alternative to conventional sandwich bread.
