Why Youโll Love This Recipe:
Uses a lot of Rhubarb
If your garden is anything like my mother-in-laws, she is begging for anyone breathing to take home some rhubarb plants! This and my Sourdough Rhubarb Cake recipe are my go-to sourdough recipes to put rhubarb to good use!
Flavor & Texture
The combination of rhubarb, when paired it with the sweetness and slight tangy flavor of sourdough in the quick bread, is unmatched! And each bite is incredibly moist with a delicate crumb. You couldn’t ask for more from this easy recipe!
Quick and Easy
Quick breads are one of my favorite recipes to make in a pinch! Made with simple ingredients you most likely already have in the pantry, it’s always delicious!
Ingredients
* To find precise measurements, scroll to the bottom of this post to find the recipe card*
Flour – I used all-purpose flour for this easy recipe.
Sugar – I used all white sugar, but you can substitute half with brown sugar for a more caramel flavor.
Baking Powder – Since this is a sourdough discard recipe, we need a little help to get the bread to rise. Double-check that your baking powder is fresh and not expired, otherwise the bread will be dense.
Salt – Any unrefined salt will do, but my favorite is Redmondโs unrefined salt for some extra minerals!
Egg – One large egg for moisture.
Milk – Non-dairy options, like almond milk, can be used as substitute.
Vanilla- For the best flavor, I always suggest using vanilla extract over imitation.
Oil – Use a neutral oil like vegetable oil or avocado oil for the most moist bread.
Sourdough Starter Discard – Active or unfed sourdough starter can be used.
Rhubarb – Tart rhubarb brings the best flavor to this sourdough quick bread!

Supplies
Rubber Spatula
Parchment Paper

How to Make Sourdough Rhubarb Bread
Preheat the oven to 350 degrees F.
Prepare a 9×5 loaf pan by greasing and lining it with parchment paper for easy removal. Set aside.
Chop the fresh rhubarb into 1/2 inch pieces. Set to the side.


In a large mixing bowl, add the flour, sugar, baking powder, and salt. Whisk until thoroughly combined.
In a separate bowl, add the milk, egg, vanilla, sourdough discard, and oil. Whisk until smooth.
Pour the wet ingredients into the dry ingredients and mix until just combined. Lastly, fold the pieces of rhubarb into the batter.

Pour the quick bread batter into the prepared loaf pan. Finally, sprinkle extra sugar on top.
Bake for 60-65 minutes, or until a toothpick put in the center comes out clean or with a few moist crumbs.
Place on a wire rack to cool slightly before slicing.

How to Store
Store leftover sourdough rhubarb bread in an airtight container or covered tightly in plastic wrap at room temperature for 2-3 days.
FAQs:
Can I use frozen rhubarb?
Absolutely! No need to thaw the rhubarb, just fold in the frozen slices of rhubarb just before baking.
When is rhubarb season?
Rhubarb season in most areas is from April to June. It is one of the first veggies of the season and it is quite bountiful!

Happy baking!

Hi! I’m currently making this recipe. I noticed it said for 2 loaves but this recipes yields 1. I also used olive oil.. ran out of avocado. Let’s hope it’s good haha
Thank you so much for bringing this to my attention. You are right, it yields 1 not 2. Hope you enjoyed it!
Fabulous. Love it.
So glad you enjoy this recipe!
Could I add strawberries to this as well? Would bread flour work instead of AP?
Hi Casey! Great questions! Iโd be a little cautious about adding strawberriesโsince theyโre so juicy, they can make the loaf too wet and affect the texture. If you want to experiment, try dicing them small and patting them dry first, or even using freeze-dried strawberries for flavor without the extra moisture.
As for bread flour, I recommend sticking with all-purpose if you can. Bread flourโs higher protein content can make quick breads more dense and gummy instead of soft and tender. Let me know if you try itโIโd love to hear how it turns out!
If I’m using active starter do i need to add baking soda.
This is so delicious! Iโm new to sourdough and tried this and it was so good and easy! Iโm going to try baking them as muffins this next go around!
Love the muffins idea! Let me know how they turn out!
Excellent recipe for using up SD discard and rhubarb. Moist and tender crumb. Didnโt change a thing. Itโs a keeper!
Thrilled you loved this recipe, Mary! Thank you for sharing.
Can this be made into muffins?
Yes, absolutely! You can definitely turn this into muffins. Just divide the batter into a lined muffin tin and bake at the same temperatureโstart checking for doneness around 18โ22 minutes. Let me know how they turn out if you give it a try!
