This Banana Bread made with a sourdough starter is a light and delicious bread full of pure banana flavor that is so good you don’t even need to add butter! For another recipe that gives you a tangy sourdough flavor, try my Easy Sourdough Brownies.
Sourdough Banana Bread
I have definitely made my share of banana bread, from my Cinnamon Sugar Banana Bread to Chocolate Chip Banana Bread. All of them are delicious, but this Sourdough Banana Bread recipe is so light and the banana flavor really comes out in this bread with every bite. It is really a bread to go bananas for😀.
I wanted more recipes to use my sourdough starter (that I had finally perfected) besides my Simple Sourdough Bread. I am happy to say this was a great idea! The more ways to use up the starter, the better.
Sourdough Banana Bread Recipe
Just in case you have never had Sourdough Banana Bread before and are thinking… does this taste sour? The answer is no. The sourdough starter acts as a yeast component in this recipe and is simply an ingredient that helps with rise and texture. This bread tastes like the most perfect banana bread you will ever make. Pure banana deliciousness!
This simple recipe is perfect for your sourdough starter. Or, just use the starter you have ready to go in the refrigerator. (Just make sure you take it out 12 hours before baking!) Either way, I think you will like the subtle added flavor that it gives to the bread.
How Long Does Sourdough Banana Bread Last?
Since this recipe makes just one loaf, it certainly doesn’t last very long here. I could probably eat the entire loaf by myself in a couple of days! Sourdough bread, in general, usually lasts for 4-5 days at room temperature. Do not store it in the refrigerator. Instead, keep it covered with a towel or in a zipped plastic bag someplace that is relatively cool. A bread box also works well.
If you want to freeze the bread, be sure to let the bread cool completely before freezing. To freeze the bread, seal the loaf into a zipped plastic freezer bag, making sure to let all the air out. You can store bread for up to 6 months in the freezer, but the longer you keep it in there, the less fresh tasting it will be. (And be sure to label it with the date!)

What’s the recipe for sour dough starter?
Made this today with discards from my starter(s)(I’m on day 5–so close!) and it was absolutely delicious. It’s true that there’s no sourdough taste at all; the bread is nice and light and so tasty! I added a quick walnut streusel topping for some crunch, so so good! Thank you!!
AWESOME to hear Abby!!! So glad you like it! <3
How do I make pancakes using the starter? Love your recipes. Thank you.
I have been testing pancakes recipes almost every day for 2 weeks… they are ok, but I want to find the BEST combination of ingredients and make sure it is perfect before sharing! So I will be, soon!
I’ve been struggling to keep up with my starter, and needed to use up some bananas that were way past eat-able. This recipe was just what I needed, and it came out amazing! I made it last night and my husband and I have already eaten more than half the loaf. Added some nutmeg and cinnamon because I like those flavors with banana.
I was going to make banana bread again, but my bananas were way past ripe so I made it into a cranberry orange bread by adding 3 Tbsp orange juice, 1 1/2 cups frozen cranberries and 1/2 cup milk. It turned out great! I love the banana bread recipe too.
WOW! Great idea, love that!
I made this and left it the oven for required time. Found it very dense and not light and fluffy like yours. Should I have cooked it longer? The toothpick cane out as cooked. The taste is wonderful. Just way too dense and heavy sadly
Oh no! So sorry. Sometimes an overmixed banana bread batter will result in a dense loaf.
Do you keep the discard out at room temp or store it in the fridge until until you have enough for a recipe??
Hi, Sheila! I work with iambaker and am happy to help with questions. Store the discard in your refrigerator until you have enough for the recipe. If you don’t have enough in a week’s time, feed the discard and continue to store it in the refrigerator until you have enough. I hope this helps. Have a great day!
This turned out very good. I was gifted some starter and kept the discard in the refrigerator until I had one cup. You can really taste the sour but in a good way. I only had 3 bananas but they were pretty big so it worked fine. I also folded in chocolate chips at the end.
I’m very excited about making this once my bananas ripen. Do you think it could be made with cinnamon like your cinnamon sugar banana bread recipe? I’m sure I could top it with the cinnamon sugar mix. But do you think I could add cinnamon to the bread part of the recipe?
Yes and yes. You can add it to the bread and over the top. 🙂
Loving this banana bread. Making it each weekend now during our shelter in place. I’m using all whole wheat flour/starter and coconut oil. I’ve started putting grated carrot and zucchini in. Great recipe!
