Got some leftover sourdough starter and some overripe bananas lying around? Make some sourdough banana bread you’ll want to have over and over.
Sourdough Banana Bread At-a-Glance:
- Uses over-ripe bananas plus a sourdough starter or discard to add moisture, rich banana flavour and extra depth.
- Combines the wet and dry ingredients carefully (often creaming sugar & banana first, mixing flour-based dry stuff later) to get a soft, tender crumb.
- Typically baked in a loaf pan (~9×5 inch) for about 50-65 mins until a toothpick comes out clean, worth letting it cool slightly before slicing.
- Clever way to reduce waste: puts sourdough discard + over-ripe bananas to good use, turning ingredients that might otherwise be thrown away into something delicious.

What is sourdough? Sourdough bread made from natural yeast (usually from flour). Unlike commercial yeast, you use a starter to make the bread rise.
Prepare your sourdough starter. If this is your first time making this, here’s a great recipe on how to make some from scratch.
Step 2: Preheat Your Oven
Preheat your oven to 350 degrees F. But if you want your bread to rise a bit more, preheating the oven to 360 degrees F will do the trick.
Step 3: Butter Your Baking Pan
Add a light coating of butter to your baking pan. This ensures your bread doesn’t stick to the pan when you try to take it out.
Step 4: Mix Your Dry Ingredients
Sift the flour, salt, and baking soda into a bowl. Sifting your dry ingredients helps them not clump together.
Step 5: Cream the Bananas
In a separate bowl, break up your bananas into smaller pieces. Next, add in your brown sugar and vanilla.
Use a hand or stand mixer to cream them until smooth.

Step 6: Add Eggs and Sourdough Starter
In the same bowl, crack the eggs one at a time until fully incorporated into the mixture. Then mix in your sourdough starter.
Step 7: Combine the Dry Ingredients
Combine your dry ingredients into your banana mixture. Do this in batches so you don’t have flour flying all over your kitchen.
Step 8: Add in the Oil and Milk
Add the oil and milk into the mixture until the liquids blend in. Don’t over-mix them so you don’t get a rock-hard loaf.
Step 9. Pour Your Batter
Pour in your batter into the buttered baking pan. Make sure your pan is only 3/4 full so you don’t get it everywhere and end up having to clean up your oven.
Step 10: Bake!
Place your batter in the oven and bake it for 60-65 minutes until the toothpick test comes out clean.
Step 11: Cool, then Serve

Let the bread cool first on a cooling rack before serving.
