Sourdough Discard Zucchini Carrot Bread with Pistachios

You’ll love this light and fluffy Sourdough Discard Zucchini Carrot Bread with pistachios and an icing drizzle for perfect sweetness and texture.

Zucchini Carrot Bread Ingredients

This zucchini carrot bread batter is very similar to muffin batter. It’s super easy to mix. The key is to mix all the dry ingredients separately from the wet ingredients before combining. You also want to ensure your wet ingredients are the right temperature before mixing them together!

The Best Bread Pan for Zucchini Carrot Bread

I picked up this fantastic non-stick bread pan at Whole Foods, and I LOVE it. It’s perfect for any bread. Click here to get one.

For this recipe, it’s best to use a non-stick metal bread pan close to a 9x5x3 dimension. Here are a few more options I’d recommend:

  • Caraway Ceramic Bread Pan
  • USA Pan 1-pound loaf pan
  • Cuisinart Loaf Pan

Should you squeeze the water out of zucchini for bread?

In some recipes, you may need to, but in this recipe, you don’t!

In some quick sweet bread recipes, you might not need to squeeze the water out of zucchini for several reasons:

  1. Moisture Balance: I designed my recipe to accommodate the additional moisture from the zucchini. The zucchini’s moisture content can help create bread that is exceptionally moist and tender.
  2. Recipe Formulation: The amount of dry ingredients (like flour and sugar) in these recipes may be adjusted to account for the extra liquid from the zucchini. This ensures the batter has the correct consistency and the bread bakes properly.
  3. Desired Texture: Some zucchini bread recipes aim for a very moist, almost cake-like texture. The zucchini’s water content contributes to this texture, making the bread soft and tender.
  4. Simplicity and Convenience: Not squeezing the zucchini simplifies the recipe, making it more straightforward and quicker to prepare. 

Should zucchini be peeled before shredding for bread?

No, you shouldn’t peel the zucchini before grating it and incorporating it into the bread. I prefer to leave the skin on for fiber, but also for a pop of color inside the bread.

The zucchini skin is perfectly healthy, especially if you use organic zucchini. So skip the extra work and leave it on! Your bread will be prettier with it.

Don’t Over-Mix the Zucchini Carrot Bread Batter!

When making quick bread one crucial tip is to avoid overmixing the batter. Overmixing can result in dense bread rather than a light and fluffy loaf. The reason behind this lies in the formation of gluten.

Gluten, a protein present in flour, gives structure to baked goods. However, excessive mixing develops gluten strands, leading to a denser texture. To prevent this, gently mix the dry and wet ingredients until just combined, ensuring there are still some lumps and streaks of flour in the batter.

This technique allows the carrot zucchini bread to rise correctly, resulting in a tender crumb and a delightful eating experience.

My other quick bread baking tip is always to use a great, non-stick metal loaf pan.

Sourdough Discard Zucchini Carrot Bread with Pistachios

You’ll love this light and fluffy Sourdough Discard Zucchini Carrot Bread with pistachios and an icing drizzle for perfect sweetness and texture. This bread is ideal for any spring or summer get-together. Pair it with coffee or tea for a lovely afternoon snack.

  • Prep: 15 minutes
  • Cook: 1 hour
  • Total Time: 1 hour 15 minutes

Ingredients

  • 2 cups all-purpose flour
  • 1/2 cup sugar
  • 1/2 teaspoon baking soda
  • 1 teaspoon baking powder
  • 2 tablespoons potato starch
  • 1 teaspoon salt
  • 1 teaspoon cinnamon
  • 1/2 tsp ground ginger
  • 1/2 cup crushed pistachios
  • 1/2 cup carrots, grated
  • 1/2 cup zucchini, grated
  • 1/2 cup unsalted butter, room temperature soft
  • 1/2 cup sourdough starter, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 cup whole milk, room temperature
  • 2 eggs, room temperature

Icing

  • 1/3 cup powdered sugar
  • 2–3 teaspoons whole milk
  • crushed pistachios

Instructions

  1. Preheat your oven to 350° F.
  2. Grease a non-stick, 5×9 (1-pound) bread pan with butter.
  3. Grate and measure out the carrot and zucchini.
  4. In a medium-large mixing bowl, combine the flour, potato starch, sugar, baking soda, baking powder, salt, cinnamon, ginger and pistachios.
  5. In a separate bowl, combine the carrots, zucchini, butter, sourdough starter, vanilla, whole milk, and eggs. Mix the wet ingredients until evenly combined.
  6. Gently fold the wet ingredients into the dry ingredients until everything is just combined. Do not over-mix. The batter should be thick, and it’s okay if there are some dry clumps.
  7. Scoop the batter into the bread pan.
  8. Bake for 40-50 minutes total. Rotate the pan halfway through.
  9. While the bread bakes, mix the icing together. Add the milk 1 teaspoon at a time, keeping the icing super thick but able to be drizzled. Crush or chop some pistachios to sprinkle on top the icing.
  10. Allow cooling for about 15 minutes in the pan, then slide the loaf out of the pan onto a cooling rack, allowing it to cool completely.
  11. Drizzle with icing and top with crushed pistachios.

    Could I use corn starch instead of potato starch? Or would you just leave it out?

    This sounds good, and I’d like to try it. However, can this, and your other bread recipes, be made with gluten-free flour? I have to be gluten-free.

      this bread can be made with GF flour, since it is a quick bread recipe. My other sourdough recipes that require kneading and rising cannot be made with GF flour.

    I dont keep potato starch or corn starch around. What is the purpose and is there a non-GMO substitute? I use tapioca flour or arrowroot starch to thicken, but is the purpose of potato starch, too? Thanks for your help!

Okay, fine, it’s not the only reason, but it’s Okay, fine, it’s not the only reason, but it’s a reaallllyy good reason to buy another pumpkin!

My new sourdough pumpkin bagel recipe is up on our blog!
https://cultured.guru

these roasted pumpkin bagels can be made savory or sweet! Both options are included in the recipe and are perfect for fall sourdough baking. 

The savory is a pumpkin, parmesan, onion (leek) flavor, and the sweet is a cinnamon brown sugar pumpkin flavor! ✨

You can also choose to use active starter or discard with yeast. It’s up to you! 

Let me know if you try baking these this weekend! 🍂🎃🥯

Google “golden beet kvass recipe” and you’ll Google “golden beet kvass recipe” and you’ll see mine, it’s the first one. 🫧✨

I only like to learn fermentation from two places: from knowing the microbes and from cultural recipes passed down in families.

I originally learned how to make kvass from a Russian food blogger, named Peter. @petersfoodadventures He grew up drinking beet kvass made by his grandfather. It doesn’t get more historically/culturally accurate than that

After learning from Peter’s blog, I developed my golden beet kvass recipe, with some slight variations of my own and a secondary fermentation to carbonate it. (Peter is credited and linked in the recipe blog too, so you can check out his original beet kvass recipe!)

Anyways, beet kvass is a delicious, sweet, bubbly beverage, not a salty lacto-ferment 🤗🫧✨

nuance is needed in the alcohol conversation. Pe nuance is needed in the alcohol conversation. 

People in Blue Zones , particularly in Mediterranean regions, often drink 1-2 glasses of wine daily with meals and among friends, enjoying organic wines rich in antioxidants. 

This contrasts with new studies that show “no safe level of alcohol.” These new studies lump together all types of alcohol (including hard liquor) consumed in unhealthy ways, without distinction of specific lifestyle and beverage consumption environment.

I think context is key. Wine is not necessarily a reason for longevity in Blue Zones, but it is a small, supportive component of a larger lifestyle that includes a fiber-rich diet, regular physical activity, strong social connections, and a sense of purpose. Consumption is limited to about 1-2 glasses per day and is almost always enjoyed with food and in the company of friends and family. 

This turns wine into a ritual that promotes social bonds. Not a toxic coping mechanism.

And type of alcohol does matter. Many Blue Zone populations, especially in the Mediterranean, drink natural, organic, or locally grown and brewed wines, which have a much higher antioxidant content and a lower sugar, pesticide, and additive content. 

Because of all of this, I think more nuance is needed in the alcohol conversation.

(Disclaimer: I am very well aware of the epidemiology that states no amount of alcohol is safe. In the general population, especially in America, drinking patterns, social patters, and lifestyle are all predominately unhealthy. So yes, for the general, average population no amount of alcohol can be considered safe.)
