Golden, buttery, and baked in a hot cast iron skillet, this sourdough cornbread checks all of the boxes. The crispy edges, tender crumb, and subtle sourdough tang make it hard to stop at just one slice. It’s the perfect side for a bowl of chili, hearty soups, stews, or your favorite barbecue meal.
What makes this recipe a little different is the simple three hour ferment before baking. The sourdough starter is mixed with the buttermilk, cornmeal, and flour and left to rest before adding the remaining ingredients. This extra step softens the cornmeal, helps break down some of the gluten in the flour, and develops a deeper, richer flavor.

Once the batter is fully mixed, it’s poured into a preheated cast iron skillet, creating that irresistible crispy crust while keeping the inside soft and tender.
You can use either active sourdough starter or unfed discard with equally delicious results, making it a great way to use whatever you have on hand. If you don’t have honey, it’s easy to substitute an equal amount of maple syrup or cane sugar.
