If you’re looking for a way to reduce waste and make a delicious snack, sourdough discard zucchini oatmeal bars are a perfect choice. This recipe combines the tangy flavor of sourdough discard with fresh zucchini and hearty oats, resulting in moist, flavorful bars that are great for breakfast, snack time, or even dessert. Plus, using sourdough discard helps you make the most of your sourdough starter, turning it into a tasty treat instead of tossing it out.
Ingredients
- 1 cup sourdough discard (unfed or fed, whichever you have on hand)
- 1 cup grated zucchini (about 1 medium zucchini)
- 1/2 cup honey or maple syrup
- 1/3 cup vegetable oil or melted coconut oil
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 1/2 cups rolled oats
- 1 cup whole wheat flour or all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon ground cinnamon
- Optional: 1/2 cup chopped nuts or chocolate chips
<1/4 teaspoon salt
Instructions
- Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it to prevent sticking.
- In a large mixing bowl, combine the sourdough discard, honey or maple syrup, oil, eggs, and vanilla. Whisk until smooth and well combined.
- Add the grated zucchini to the wet ingredients and stir to incorporate evenly.
- In a separate bowl, whisk together the oats, flour, baking powder, baking soda, cinnamon, and salt.
- Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Be careful not to overmix, as this can make the bars dense.
- If desired, fold in chopped nuts or chocolate chips for added texture and flavor.
- Pour the batter into the prepared baking pan, spreading it evenly with a spatula.
- Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
- Remove from oven and let cool in the pan for about 10 minutes. Then transfer to a wire rack to cool completely before slicing into bars.
Tips
- Use freshly grated zucchini for the best moisture and flavor. Squeeze out excess water if your zucchini is very watery to prevent soggy bars.
- If you prefer a sweeter bar, increase honey or maple syrup by 1-2 tablespoons.
- For gluten-free options, substitute the flour with almond flour or gluten-free baking mix, but adjust the baking time as needed.
- Store the bars in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. To keep them fresh longer, freeze individually wrapped bars for up to 3 months.
Serving Suggestions
These zucchini oatmeal bars are versatile and can be enjoyed on their own or paired with a dollop of yogurt or a splash of milk. They make an excellent portable breakfast or snack, and their moist texture pairs well with fresh fruit or a cup of tea.
Variations
- Chocolate Chip Zucchini Bars: Add 1/2 cup chocolate chips to the batter for a richer, sweeter treat.
- Nutty Version: Incorporate 1/2 cup chopped walnuts or pecans for added crunch.
- Vegan Adaptation: Replace eggs with flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg) and use plant-based oil and sweetener.
- Spiced Version: Increase cinnamon or add nutmeg and ginger for a more warming flavor profile.
Storage and Reheating
Store the bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to 7 days. For longer storage, wrap individually and freeze for up to 3 months. To reheat, microwave a bar for 10-15 seconds or warm in a preheated oven at 350°F (175°C) for 5-7 minutes. They are best enjoyed warm or at room temperature to preserve their moist, tender texture.
Frequently Asked Questions
Can I use unfed sourdough discard for this recipe?
Yes, unfed sourdough discard works perfectly. Its tangy flavor adds depth, and since it hasn’t been fed recently, it tends to be more sour, which can enhance the flavor of the bars.
How do I prevent the bars from turning out too dense or dry?
Be careful not to overmix the batter, as this can develop gluten and make the bars dense. Also, ensure you don’t overbake; check for doneness at the 25-minute mark to prevent dryness.
Can I substitute the oats with other grains?
While oats provide moisture and texture, you can substitute them with quick oats or rolled spelt flakes. For gluten-free options, use certified gluten-free oats. Other grains like quinoa flakes can be experimented with, but may alter the texture slightly.
What if I don’t have zucchini?
If zucchini isn’t available, you can substitute with grated carrot, apple, or mashed banana. Keep in mind that these alternatives will change the flavor and moisture content slightly.
Do I need to peel the zucchini?
No, peeling is not necessary. Just wash and grate the zucchini, then squeeze out excess water to prevent sogginess in the bars.
Can I add spices or flavorings?
Absolutely! Cinnamon is already included, but you can add nutmeg, ginger, or even a pinch of cardamom to customize the flavor profile to your taste.
