An easy and moist Sourdough Banana Bread Recipe that is loaded with bananas. This is one of my favorite overripe banana recipes that features a sourdough starter.
What makes a quick bread recipe sourdough?
I'm so glad you asked. The main difference between a traditional banana bread recipe and a sourdough banana bread recipe is the addition of sourdough starter.
A basic banana bread recipe is considered a quick bread. This means that it doesn't contain yeast and can be baked immediately after mixing all of the ingredients together. A quick bread is quick, get it?
Sourdough banana bread is a very flexible recipe and can be baked immediately as a quick bread, or fermented for up to twenty-four hours. Fermentation breaks down the wheat grains and creates a loaf that is both feeds our good gut bacteria and is easier for our bodies to digest.
What does a sourdough starter do?
A sourdough starter is a culture of wild yeasts and beneficial bacteria that is made with flour and water. When I'm feeling fancy, which is almost never, I like to talk about how this is mostly lactic acid bacteria. When the lactobacillus is fed flour and water, it begins converting the starches in the flour into broken down byproducts.
Every starter will be slightly different, due to the temperature and microbes in your home. A loaf of sourdough that tastes mild and mellow will likely contain higher amounts of lactic acid, while a sharper and more sour loaf probably has higher levels of acetic acid.
Tips for a delicious sourdough banana bread
- Select bananas that are very ripe. They should be less yellow and more brown and the flesh should be almost unappealing. Don't worry, this means the bread will be sweeter and have a more caramel flavor!
- Whole wheat or gluten free flour substitutes can be used in place of organic white flour, just know that you may have to adjust the recipe slightly.
- My favorite way to prepare my loaf pan is by lining it with parchment paper. This eliminates the need for cooking spray and makes cleanup so much easier!
- Quick breads tend to be fussy about texture. When combining the wet and dry ingredients, stir until just blended. Over-mixing can create a dense, flat loaf.
How to bake sourdough banana bread video
This week I stepped out of my comfort zone and created a video to go along with this recipe. It is the very first video I've ever made, and I hope you like it! I'm a very visually learner and love watching other people cook, so maybe you will to! Just typing this makes me feel sweaty, but I know you'll be understanding with my amateur editing skills (please!).
This recipe has been modified from a recipe that Lisa shared and our family has fallen in love with. I modified her recipe with more starter and flour to create a taller and more domed loaf. Thank you, Lisa!
