Delicious Sourdough Zucchini Muffins Recipe
These sourdough zucchini muffins are a delicious way to put that discard to good use. This easy recipe is irresistibly spiced, moist, and has the health benefits of the abundance of zucchini lying around.

Growing zucchini is great, but man oh man, does it provide an abundance of harvest! Eventually, you will be giving away extra zucchini to anyone who will take them and still have some that need something done with them. This great recipe is perfect for all that fresh zucchini. We can never have enough zucchini recipes or sourdough discard recipes, am I right?! Even better when we can mix the two!
Tips For Making This Recipe:
- This recipe calls for leftover starter, but if you want to use active sourdough starter, it can be used. For a more tangy flavor, use sourdough discard that hasn’t been fed in a day, or allow to long ferment. For a less tangy flavor, use an active sourdough starter.
- Throw some delicious optional ingredients into these sourdough zucchini muffins. Things like chocolate chips or dried fruit would be great.
- Double or even triple this recipe and freeze the extra. They are great to pull out of the freezer for a quick breakfast or snack on the go, which is perfect for a busy mom!
- For easier digestion, long ferment this recipe.
- Don’t feel like muffins? Make this into a delicious bread by baking for 50-60 minutes or use mini loaf pans and bake for 35-40 minutes.
