Sourdough French Toast Recipe: A Game Changer
French toast is already amazing—but have you ever tried it with sourdough? That little bit of tang in the bread balances out the rich, creamy goodness from the eggs and milk, creating layers of flavor. Instead of being just sweet and heavy, it has depth and contrast.
The texture is another major upgrade. No soggy slices here. Sourdough holds up beautifully, soaking in just the right amount of custard while staying firm enough to get perfectly crispy, golden edges and a soft, custardy center.
And then there’s the flavor. Regular bread just can’t compete. Sourdough’s natural fermentation gives it a subtle complexity—a little tangy, a little nutty, just the right amount of chew. Add maple syrup, fresh berries, or a sprinkle of cinnamon sugar, and suddenly, your French toasts go from good to unforgettable.
This guide covers everything you need—why sourdough is the ultimate choice, the best techniques for that flawless texture, and, of course, some delicious recipes to take your breakfast to the next level.

The History of French Toast and Sourdough
French toast has been enjoyed for centuries, dating back to ancient Rome, where it was known as “pan dulcis.” Soaking stale bread in milk and eggs before frying was a practical way to use leftovers and create a hearty meal. Over time, the dish spread across Europe and beyond, taking on different names and variations in each culture.
Sourdough bread has an even older history, dating back thousands of years. It was the primary form of leavened bread before commercial yeast became widely available. The natural fermentation process gives sourdough its distinct tang and makes it easier to digest compared to conventional bread. Combining these two traditions results in a dish that is both flavorful and historically rich.
Why Sourdough Bread is Perfect for French Toast
Sourdough bread has several characteristics that make it ideal for French toast:
- Sturdy Texture: Sourdough’s chewy crumb holds up well when soaked in the custard mixture.
- Unique Flavor Profile: The tanginess of sourdough pairs perfectly with sweet and savory toppings.
- Nutritional Benefits: Sourdough fermentation breaks down gluten and phytic acid, making it easier to digest than regular bread.
