All the ingredients in this recipe are simple and straightforward, but each one plays a crucial role in crafting the perfect taste, texture, and color. Together, they create that luscious custard soak and beautifully caramelized finish that make this French toast so special.

4 large eggs: They form the rich custard base that binds everything together and gives structure.
½ cup sourdough discard (unfed starter): Adds a subtle tang and depth, elevating the flavor beyond regular French toast.

¾ cup whole milk: Or a mix with cream for extra richness—it softens the bread and makes the custard creamy.
3 tablespoons maple syrup: Natural sweetness that mingles beautifully with the sourdough flavor.
1 teaspoon vanilla extract: Enhances the overall aroma and rounds out the taste with warmth.

½ teaspoon ground cinnamon: For that classic spicy note everyone loves in French toast.
⅛ teaspoon salt: Balances the sweetness and heightens the flavors.
Butter or neutral oil: Essential for a golden, crisp cook on the skillet or griddle.

4 to 6 slices sourdough bread (¾ to 1 inch thick): Thick slices soak up the custard perfectly without falling apart.
Granulated sugar: Used for that delectable caramelized sugar finish that adds crunch.

Directions

Step 1: In a large shallow dish—I like to use a pie plate or baking dish—I whisk together the eggs, sourdough discard, milk, maple syrup, vanilla extract, ground cinnamon, and salt until the mixture is smooth and well combined. It only takes a couple of minutes and sets the stage for amazing flavor.

Step 2: Next, I dip each slice of sourdough bread into the custard mixture, letting it soak for about 30 to 45 seconds on each side. The goal is to let the bread absorb enough custard to be flavorful and tender, but still hold its shape when cooking. This soak time is critical to avoid sogginess.

Step 3: I preheat a large skillet or griddle over medium heat and add butter (or a combination of butter and neutral oil) to coat the surface generously. This helps create that irresistibly golden-brown crust that everyone loves.

Step 4: Carefully placing the soaked slices on the hot skillet, I cook them for 2 to 3 minutes per side. I watch closely for a deep golden brown color and a slightly crisp texture before flipping. Adding a little more butter or oil between batches keeps the cooking surface perfectly greased.

Step 5: For the caramelized sugar finish that really makes this Sourdough French Toast Recipe shine, I brush the cooked top lightly with melted butter and then sprinkle an even layer of granulated sugar over it. Flipping the slice once more, I cook it for another 30 to 60 seconds until the sugar melts and forms a beautiful golden crust. This step adds a sweet crunch that’s pure magic.

Step 6: Finally, I plate the French toast immediately and serve it with my favorite toppings like extra maple syrup, a dusting of powdered sugar, or fresh berries for a burst of freshness. The warmth and texture are at their best right away.

Servings and Timing

This recipe makes about 4 servings, perfect for a small family or gathering. The prep time is quite short, around 10 minutes to mix and soak the bread. Cooking usually takes about 15 minutes, depending on your skillet size and heat control. So overall, you’re looking at approximately 25 minutes from start to finish, with no resting or cooling time needed. It’s wonderful for when you want a quick yet impressive breakfast or brunch.

When I serve this Sourdough French Toast Recipe, I love to keep things simple but delicious. A classic pairing for me is warm maple syrup and fresh seasonal berries—like raspberries or blueberries—because the tartness perfectly cuts through the richness and brings a vibrant pop of color to the plate. A light dusting of powdered sugar adds a touch of elegance and sweetness, making it feel special enough for guests or celebrations.

If I’m aiming for something a bit more indulgent, I’ll add a dollop of whipped cream or crème fraîche. It adds creaminess and a lovely tang that complements the sourdough flavor beautifully. For a crunchy contrast, chopped toasted nuts like pecans or walnuts sprinkled on top give great texture that surprises and delights.

I also love pairing this dish with a hot beverage like freshly brewed coffee or a spiced chai latte in the morning. For brunch occasions or celebrations, a mimosa or a glass of sparkling wine feels festive and pairs wonderfully with the sweet and tangy notes. I recommend serving the French toast hot or warm to enjoy the full effect of the caramelized crust and custardy interior. I usually plate medallion-sized servings so each person can savor multiple bites without feeling overwhelmed—a perfect balance of comfort and refinement.

Variations

One of the things I enjoy about this Sourdough French Toast Recipe is how easy it is to customize based on what you have in your kitchen or your dietary preferences. If you don’t have sourdough discard, you can substitute with a little buttermilk for tang or skip it for a more traditional sweet French toast. Just know you’ll miss that signature mild sourdough tang that I love. For dairy-free versions, swapping the milk for almond, oat, or coconut milk works beautifully, and vegan egg substitutes can be used to make it plant-based.

If you want to play with flavor, sometimes I add ground nutmeg or orange zest to the custard for a subtle twist. For a richer dish, a splash of heavy cream or half-and-half can replace some of the milk, making the custard more luxurious. Cooking-wise, while I usually pan-fry, baking the soaked sourdough slices on a greased sheet at 375°F for 15-20 minutes, flipping halfway through, is an easy hands-off approach that still yields a crisp finish.

Another fun variation is topping the French toast with caramelized apples or sautéed berries right in the pan after cooking. It’s like creating a delicious fruit compote on the side and adds natural sweetness and color. Honestly, feel free to get creative and make this recipe your own—it’s wonderfully adaptable!

Storage and Reheating

Storing Leftovers

If you happen to have any leftovers (though they usually disappear quickly!), I store them in an airtight container in the refrigerator. I find a shallow container lined with parchment paper prevents sticking and keeps the pieces intact. Properly stored, they’ll keep well for up to 2 days without losing too much texture or flavor.

Freezing

This Sourdough French Toast Recipe freezes quite well, which is fantastic for meal prep or quick breakfasts later. I like to flash freeze individual slices on a baking sheet first to prevent sticking, then transfer them into a freezer-safe zip-top bag or container. They can stay frozen for up to 1 month. When ready to use, I find reheating from frozen works best to maintain the caramelized crust and custard texture.

Reheating

To bring back the crispness and warmth, I prefer reheating leftover or frozen French toast in a skillet over low-medium heat, flipping gently to avoid burning. Alternatively, the toaster oven works wonderfully for reheating while keeping it crisp. I avoid microwaving because it tends to make the bread soggy and chewier, which loses that special caramelized texture. Adding a tiny pat of butter while reheating revives the richness and helps restore that fresh-cooked flavor.

FAQs

Can I use regular bread instead of sourdough for this recipe?

Absolutely! You can substitute any sturdy bread like brioche, challah, or country white bread. Just remember that sourdough discard adds a unique tangy flavor and slight chewiness that regular bread won’t provide. Using thicker slices helps maintain structure in any case.

What if I don’t have sourdough discard on hand?

No worries! You can leave it out completely or substitute with plain yogurt or buttermilk to add a mild tang. The custard will still be delicious, just lacking that distinct sourdough note. Adjust the amount slightly if substituting with yogurt to keep the liquid ratio balanced.

How do I get the caramelized sugar crust without burning it?

The key is cooking it over medium to medium-low heat and keeping a close eye. After sprinkling sugar on a butter-brushed slice, flip it gently and cook for just 30 to 60 seconds until it melts and turns golden. If your heat is too high or you leave it too long, the sugar can burn quickly and taste bitter, so patience is key.

Can I prepare the custard mixture ahead of time?

Yes! You can prepare the custard a few hours in advance and keep it covered in the fridge. However, since it contains eggs and sourdough discard, it’s best not to keep it too long (ideally no more than 4-6 hours) to maintain freshness and safety.

What toppings do you recommend pairing with this Sourdough French Toast Recipe?

I’m a big fan of classic toppings like maple syrup, fresh berries, and powdered sugar for that simple and elegant finish. For a more indulgent treat, whipped cream, chopped nuts, or fruit compotes work beautifully. You can even add a drizzle of honey or a sprinkle of cinnamon for extra flavor. The options are endless based on your mood!

Conclusion

I can’t recommend this Sourdough French Toast Recipe enough if you want a breakfast that feels both decadent and comforting without a fuss. It’s the perfect way to use up sourdough discard and turn it into a dish that delights your whole family or guests with its rich flavor and irresistible texture. Give it a try—you just might find it becoming your new favorite go-to brunch classic!
