We make a banana bread at least once a week here. Our banana bread passion goes way back. For example, this is the very first one shared here. It's a classic recipe and I use mom's recipe that she taught me some years ago.

It actually was one of the first recipes I learned how to bake. It could all be mixed together by hand. I usually make two and end up giving one to my neighbor or to my brother's family.

If you happen to have a sourdough starter and aren't sure what to make with the discard, this is the recipe! No more guilt every week when it's time to toss out the discard…you could make an easy banana bread.

There was a time when I had a sourdough starter in my fridge. I made a sourdough pizza and sourdough pie (so GOOD!). But of course, a hurricane happened and we lost power and I lost my starter.

My sweet husband brought me some of his sourdough starter from work a couple weeks ago and it has been sourdough everything here since then. Now to find the time to share all the recipes!

This Healthy Sourdough Banana Bread is the only banana bread I'll ever make with discard-moist, just sweet enough, and always topped with cinnamon sugar. If you've got a sourdough starter, this is your new go-to breakfast loaf.

🍽️ Step-by-Step: How to Make Sourdough Banana Bread

It all starts out with the bananas! First thing you have to do is make sure you have set aside some really ripe bananas. The more ripe, the more naturally sweet and moist your bread will be! Even if they seem they've gotten a little dark, don't throw them out! Use them for this recipe!

Gather all the rest of your ingredients. It's classic banana bread ingredients, like flour, baking powder and soda, salt, sugar, oil (you could use vegetable or coconut oil), eggs (use flax eggs to make it vegan).

I used my sourdough starter (unfed...it's the portion I was discarding this week) and a little bit of unsweetened coconut yogurt. You could use a dairy yogurt or more sourdough starter.

Here is my new love: my sourdough starter!

  • Step 1: Mash the bananas.
  • Step 2: Stir together the dry ingredients.
  • Step 3: Combine the wet ingredients.
  • Step 4: Combine them all together.

I like to use a spatula to make sure I'm folding it all together and getting all the ingredients from the side of the bowl. It is all mixed together by hand. If you prefer to use a mixer, you could do it all with your electric mixer.

Using up sourdough discard:

  • Make sourdough pancakes or waffles for a delicious breakfast or brunch option.
  • Whip up some sourdough crackers for a savory snack.
  • Bake sourdough discard into savory muffins or bread rolls.
  • Use it as a starter for a flavorful sourdough discard bread.
  • Incorporate it into pizza dough for added flavor and texture.
  • Experiment with sourdough discard in recipes like this banana bread or other quick breads for a tangy twist.

🫙 Leftover and storing

  • Room temperature: Banana bread can keep stored at room temperature for up to 3 days as long as it's wrapped tightly in plastic wrap and kept in an airtight container.
  • Refrigerate: Wrap it tightly and keep in an airtight container, or keep it in a large zipped lock bag. It will keep for up to a week stored correctly in the fridge.
  • Freeze: You could wrap the whole loaf tightly with plastic wrap and a layer of aluminum foil and then place in a large zipped lock bag. Best way to freeze would be to cut into individual slices and enjoy, wrap tightly with plastic wrap and store in zipped lock freezer bag. Stored correctly should keep fine 2-3 months.

Variations & Substitutions

  • You can substitute the vegetable oil for melted butter or coconut oil.
  • To make this recipe vegan, you can use a flax egg instead of eggs.
  • For a gluten free option, you can use an all purpose gluten free baking mix in place of the all purpose flour.
  • If you don't have coconut yogurt, you can use plain Greek yogurt.
  • You can omit the cinnamon-sugar topping if desired.
  • To make a chocolate chip version, add ½ cup semi-sweet chocolate chips to the batter.
  • Other mix in ideas could be chopped nuts, raisins or dried cranberries.

☑️ Pro Tips for Baking With Sourdough Discard

  1. Mash the bananas until they are really smooth. If you have any lumps, they will be visible in the finished loaf.
  2. For the best results, use dark brown sugar. This will give a lovely warm molasses flavor to your banana bread.
  3. Make sure to measure both the all-purpose flour and sourdough starter correctly. Too much or too little of either can cause your loaf to be dry or gummy.
  4. If you want to make this recipe vegan, you can substitute the eggs for chia or flax eggs, and use a plant-based yogurt to replace the coconut yogurt.
  5. Once your banana bread is finished baking, let it cool completely before slicing into it. This will ensure that it holds its shape and doesn't crumble as you slice into it.

What to serve with easy sourdough discard banana bread?

Banana bread can be enjoyed on its own or paired with different accompaniments.

  • Goes really nicely with a small bowl of strawberries, blueberries, or raspberries
  • A dollop of Greek yogurt or whipped cream for added creaminess
  • Nut butter, like almond or peanut butter, for a protein boost
  • A sprinkle of chopped nuts or seeds for a little bit of extra crunch and nutrition
  • If you want an extra touch of sweetness, a little drizzle of honey or maple syrup for added sweetness
  • It's extra cozy serving it with a cup of hot tea, coffee or cappuccino.

❓ FAQ'S

How ripe should bananas be for banana bread?

For the best flavor and taste, seek out ripe bananas; they should have a soft texture and be mostly brown with very minor yellow tones still visible on their peel.

Can I freeze overripe bananas?

Absolutely! You have the choice to preserve your bananas up to 3 months - whether you prefer them unpeeled or diced into bite-sized chunks.

Why is my sourdough banana bread lumpy?

You can try mixing it a little longer, but it's normal for the bread to be a little lumpy.

Is sourdough better or worse for you?

Sourdough bread is generally considered to be healthier than white bread since it has more vitamins and minerals, as well as a lower glycemic index. However, the health benefits depend on the ingredients used to make the sourdough bread. For example, if your sourdough contains refined sugar or unhealthy fats, then it may not be as healthy as other options.

Is sourdough healthier than yeast bread?

Sourdough bread is often considered healthier than yeast bread because it has a lower glycemic index, more vitamins and minerals, and fewer calories. Additionally, the fermentation process used to make sourdough can help pre-digest some of the starches in wheat flour, making them easier for your body to digest.

Is sourdough banana bread good?

Yes, it is very good! The sourdough discard adds a subtle tanginess that complements the sweet flavor of the bananas, creating a unique and complex taste profile.

Can you make muffins with this banana bread recipe?

Yes! You could easily make this recipe into muffins! Simply prep your muffin pan with baking spray (or butter)and fill a tin ⅔ full. Bake for 15-20 minutes or until golden brown, or your tester comes out clean. The muffins do freeze great and the kids just love them!

How do you make banana bread in a healthy way?

To make healthier banana bread, sub out the all-purpose flour with whole wheat flour to add in some fiber. Reduce the sugar or substitute the sugar with some honey. Additionally, incorporate unsweetened applesauce or Greek yogurt in place of some of the oil or butter to lower the fat content.

    This sourdough banana bread recipe is delicious and so easy to make! I'm always on the lookout for new sourdough recipes to try, and this one is a favorite!

  2. 5 stars
    One of my favorite breads is the sourdough. I didn't know how good the banana added to the sweetness til I made this. I'm totally making this again!

  3. Hello!!

    Can I substitute regular all-purpose flour for einkorn all-purpose flour and would I need to change the ratio of flour?

    1. Typically Einkorn Flour can be substituted in a 1:1 ratio with all-purpose. I never made the sourdough banana bread with Einkorn flour, so I'm not sure how it will turn out (and not sure if it will require tweaking the recipe a little). You're welcome to try the recipe as it is replacing with the Einkorn flour and as you're making the batter, if you're an experienced baker, you should be able to tell if the batter is the right consistency, and adjust if you need to. I hope it turns out!

  4. 5 stars
    Amazing recipe! The loaf was so light and airy, not dense. Tender and so delicious.
    I used some left over active starter from bread baking and combined
    it with some discard. About half and half.
    This is unsurpassed by any banana bread I have made or eaten.

    Thank you so much! I am looking forward to trying your other recipes.

    1. Hi Susan-Thank you for taking the time to leave a comment. I'm so happy you loved the recipe! Thanks for explaining how you used some discard and and some active starter from bread baking...I'll have to try it like that next time! Happy Baking! XX

  5. I save my discard in a jar in the fridge (I do no feed it). Can I use that or should ot be fresh discard?

    1. Hi If you just removed the discard and put in the fridge, go ahead and use it. I have stored my discard overnight in the fridge and used it next morning. But it should be fine in the fridge for up to 1 week:) Hope that helps!

  6. 5 stars
    I did not put cinnamon sugar on it because it would be too sweet. I added a teaspoon each of cinnamon and mixed spice to the mix. I will make this again as it is not overly sweet. I would add some more spice and maybe chipped walnuts. Easy recipe and good use of sourdough discard.

    1. Hi Bridie...I'm really happy you enjoyed the bread and it's so kind of you to take the time to leave such a lovely review! Happy Baking! XX

    This was superb. Always hunting for sourdough discard recipes, and this recipes trumps any banana bread I've tried. The crust is lovely, so moist and tasty. Used half whole wheat and added nuts. Based on others comments I will use all whole wheat next go round. This will be my go-to from here on.

    1. Hello Elissa-So very happy you enjoyed it...this is definitely our favorite banana bread recipe. Love that you added nuts and used some whole wheat. And all whole wheat for next time sounds perfect!! Happy Baking! XX

    I made this last night, yummy! I used applesauce instead on oil, used all starter instead of yogurt, oat flour and no sugar. Wonderful texture and taste. Only lightly sweet which means I can top it with whatever I want to sweeten it. Thank you!

    1. Hi Cassandra-Thank you for letting me know you enjoyed the recipe. Love that you subbed in apple sauce and all starter. And no sugar...fantastic!! Sounds amazing! Happy Baking! XX

    2. Hi Kay-I messaged Cassandra on Pinterest where she mentions she subbed in applesauce...she responded that she used a 1/4 cup applesauce. Hope that helps!

  10. 5 stars
    Love how it comes out soft with a little crunch on the outside. Can I add 1/2 cup of walnuts to the recipe? Thank you!

    1. Hi Irene-Thank you! Yes, that makes it extra delicious! I think that's a great idea! Happy Baking! XX

  11. 5 stars
    I loved this banana bread recipe! I made this a month or two ago and am making it again tonight! I doubled the recipe and added chocolate chips last time, and it was so good. If my memory is correct, I also subbed sour cream in for part of the yogurt as I ran out part way. Whatever I did, it came out great! Thanks for sharing this recipe with us!

    1. Hi Irene-thank you and thanks so much for letting me know! Great idea to double the recipe!! Happy Baking! XX

    Oh my! Your sourdough banana bread recipe is the best banana bread I have ever baked! Seriously, I stopped making banana bread years ago because no recipe produced a bread that wasn't either burnt on outer edges while cooked through the center, or just right on the outer edges and a glummy mess on the interior.
    The ratio of flour to sugar is perfect.
    I used 100% whole wheat flour and added 1/2cup walnuts. It came out perfect. Thank you!

    1. Hi Carol-Thank you for letting me know! Really happy you enjoyed it 🙂 Great to know you subbed in 100% whole wheat and some walnuts...that sounds fantastic! Happy Baking!! XX
