As an environmental scientist, I am always trying to find ways to combat food waste. And when avoiding food waste tastes this good, I think it’s something we can all get behind.

Green tip: Bread is one of the most wasted food products in the U.S. because of our tendency to throw it out as soon as it’s stale. Reduce your contribution to food waste by revitalizing your stale bread with this Sourdough French Toast!

Sourdough French Toast Ingredients

The amount of egg wash will vary slightly depending on the size of your eggs and the size of your sourdough loaf.

Depending on these two factors, this recipe will require 4-6 slices of sourdough to use up the egg wash you prepare.

Here is everything you’ll need:

  • Sourdough Bread. It makes for an awesome contrast to the otherwise super sweet French Toast.
  • Eggs. Eggwash is critical to make any kind of french toast.
  • Milk. Or half n half or heavy cream for moisture.
  • Brown Sugar. For sweetness.
  • Vanilla Extract. For flavor.
  • Cinnamon. For warmth and more flavor.
  • Butter. To fry in.
  • Maple Syrup. To serve with.

Sourdough French Toast Tips and Tricks

Crack Your Eggs First

In this and all recipes, cracking your eggs in a separate bowl or into your bowl first is the best way to ensure you avoid egg shells in your food.

Green tip: Did you know you can compost egg shells? Read all about it in this article on composting egg shells!

It also eliminates any risk of the rare but dreadful bloody egg.

Whisk Your Wash

Add the rest of your egg wash ingredients to the cracked eggs. Whisk your egg wash thoroughly to distribute your sugar and cinnamon, and to get it nice and airy.

We want a smooth, creamy egg wash to dunk our sourdough in for a delectable French toast.

Get Your Pan Hot

Melt your butter in a pan over medium heat, and allow it to get hot. You want your French Toast to sizzle when it hits the butter.

Green tip: Look for organic and palm oil-free butter if you can. Buying organic means you are supporting farms that do not use damaging pesticides and fertilizers, and palm oil production is a huge driver behind deforestation.

Do the Dip

For the best texture, you want to just dunk your bread in, coating it on both sides. It’s best not to let it sit and soak.

Over-soaking the bread in the egg wash will land you an overall soggy French toast.

Get it Golden Brown

Your butter is already hot, so you should get that incredible sizzle sound when you place your egg-washed bread in it.

Give it about 5 minutes before peeking underneath. If it’s golden brown, it’s time to flip!

Avoid overcrowding your pan to allow enough room for easy flipping. I usually just cook two slices at a time.

Once you flip your French Toast, let it cook on the second side until golden brown. Again this should take about 5 minutes over medium heat.

How to Store and Reheat Leftover French Toast with Sourdough

French toast will stay delicious for 5-7 days wrapped and sealed in the refrigerator after preparing it. You can also freeze it for up to a month!

From the fridge, reheat on a frying pan for about 5 minutes on each side, until thoroughly heated through. You can also reheat it in the toaster oven or the oven at 375°F for 10 minutes from the refrigerator or 15 minutes from frozen.

The microwave will work in a pinch but does tend to make it a little soggy.

If you have extra egg wash, you can save that, too. Store it in an airtight container in the refrigerator to make more French toast over the next 2-3 days.

Sourdough French Toast Frequently Asked Questions

Classic French Toast is often made with a softer, eggier bread like challah or brioche. For a new twist on the classic, try it with Sourdough bread! It provides a beautiful contrast to the otherwise sweet breakfast.

Can I freeze French Toast?

Yes! French Toast can be frozen for up to 4 weeks when stored in an airtight, freezer-safe container.

To reheat, bake in the oven for 10 minutes at 375°F. You can also reheat your French Toast on a pan in a little bit of butter over medium heat for about 3 minutes on each side.

  • Crack your eggs into a shallow bowl and add milk, vanilla extract, brown sugar, and cinnamon. Whisk until combined to form your egg wash.
  • Add about 2 tablespoons of butter to a large frying pan over medium heat and allow butter to melt, tilting the pan to coat the bottom with butter.
  • Once your pan is hot and butter is melted, dip bread into the egg wash, one slice at a time, coating both sides and transferring immediately to the hot pan.
  • Allow your French Toast to fry for 2-5 minutes before flipping and cooking on the other side. Both sides should be golden brown.
  • Repeat for all 4-6 slices of bread, adding more butter to the pan as needed.

Pro Tips

  • It’s best just to dip the bread in the egg wash, rather than letting it soak. This will help you avoid soggy French toast.
  • Keep the French Toast warm in the oven at 200°F until ready to serve.
  • Don’t overcrowd the pan—it will make your French toast harder to flip.
  • Depending on the size of your eggs, there will be enough egg wash for 4-6 slices of French toast.

    A co-worker told me this tip: if you don’t have any stale bread, lightly toast the bread in the toaster! It works great! No soggy french toast falling apart on you but soaks up the goodness.

    I made these for my fiancé and he absolutely loved them! Plus, such an easy recipe to follow. I subbed almond milk for regular milk + it worked super well!

    1. Yay! I’m so glad to hear that, Chelsea. Your fiancé is a lucky person to have these made for them — and thank you for letting me know about the substitution!!
