Sourdough Banana Bread with Walnuts
How about a loaf of real banana bread? One that’s made with sourdough, wholemeal flour and no added sugar? This sourdough banana bread does all of this and more. And it’s not only healthy, it’s really delicious.
I’ve been contemplating the creation of a sourdough banana bread for a long time now. A loaf that’s just like real bread rather than cake. Finally I’ve made one and I’m really pleased with it. I’ve added the classic ingredients of walnuts and cinnamon, but the only sweetness comes from the bananas.
Banana Sourdough Bread with Walnuts
This recipe for banana sourdough bread is perfect for using up squishy bananas. It’s an easy loaf to make if you have a stand mixer. But the dough is quite wet, so whilst it’s not impossible, it’s a bit harder to knead by hand. This recipe makes one large loaf or two smaller ones.
As you can see from the photo below, I didn’t make this bread in a tin. Because it’s a soft dough, however, the loaf goes a bit flat. I don’t mind this, especially as it cooks faster. But if you’d prefer a more standard shape, use a tin or tins.
What’s in the Loaf?
I based this banana bread on my standard rye sourdough bread recipe. Because of the addition of bananas, however, the dough is wetter than it normally is. So I’ve used more flour, which creates a particularly large loaf. The flour is a mix of strong wholemeal and wholemeal spelt. The bread thus rises well because of the strong flour and has a soft texture because of the spelt.
Feel free to use a different sourdough starter. I’m wedded to rye. It’s robust, needs little attention and can be used to make any kind of sourdough bread you like. Recently I lost my ten year old sourdough starter and I was completely bereft. When I’d more or less come to terms with its loss, Monica Shaw from Smarter Fitter came to my rescue and sent me some of hers. Thank you so much Monica.
As well as walnuts and cinnamon, I’ve also added linseeds to the mix. The reason is twofold. They help to absorb liquid and they’re good for you. In fact I always add them to my sourdough breads. They’re high in omega 3 fatty acids and great for the digestion. I should add that the bread is entirely vegan, but I sort of take that as read when it comes to sourdough.
So What’s it Like?
Well, apart from the weird purple tinge that the bananas give, this sourdough banana bread is just fabulous. It has a good texture, a lovely flavour and is slightly sweet from the banana and cinnamon. Plus you get a bit of crunch and additional flavour from the walnuts. If you don’t like walnuts, just leave them out.
Spread it with butter or a nut butter and that’s really all you need. However, its also delicious toasted and spread with honey. It even goes well with plain mild cheeses like cheddar, Lancashire, Cheshire, Gloucester or Caerphilly.

Sourdough Banana Bread – The Recipe
Sourdough Banana Bread
- 75 g rye starter
- 300 g wholemeal spelt flour
- 300 g strong wholemeal flour
- 4 overripe bananas
- 50 g walnuts – chopped
- 1 tsp cinnamon
- 25 g linseeds
- 1 ½ tsp sea salt
- The night before baking the bread, mix the rye flour with 450ml of warm water in a large bowl. Add the sourdough starter and stir well. Cover loosely with a plastic bag and leave to ferment overnight.
- In the morning remove 75g of the ferment into a covered glass jar and place in the fridge until the next time a sourdough starter is needed.
- To the remaining ferment, add the wholemeal flours, peeled bananas, linseeds, cinnamon, salt & walnuts. Knead in a stand mixer for ten minutes. The mixture is quite wet, so it’s a bit more difficult to do by hand, but not impossible.
- Dust a proving basket with flour, then press the dough into it. Alternatively, form the dough into a freestyle loaf and place on a greased or lined baking tray. As the dough is quite a soft one, a free style loaf will flatten out. For a more uniform loaf, place the dough into a 1 kg/2lb loaf tin or two smaller tins.
- Cover loosely with a plastic bag, ensuring it doesn’t touch the dough and leave to prove until the loaf has risen by about ⅓. This could be anything from 2 to 6 hours depending on the temperature of the room and the liveliness of the starter.
- Turn the loaf out of the proving basket, if using, onto a greased baking tray. Otherwise, dust with a little spelt flour and slash the top 2-4 times with a sharp knife if liked.
- When, or just before, you think the loaf is ready for baking, turn the oven on to 220℃ (425℉, Gas 7).
- Place the bread in the oven and turn the temperature down to 200℃ (400℉, Gas 6). Bake for 40 minutes or until the bread sounds hollow when the base is tapped. Allow a further 10 minutes or so if baking in a tin. Place on a wire rack to cool.
