There’s something innately comforting about baking your own bread. The gentle kneading, the patient rise, the golden crust emerging from the oven—every step connects you with a timeless kitchen ritual. Among the many varieties of homemade bread, pull-apart buns stand out for their shareable charm and soft, fluffy texture. Today, we’re taking that concept a step further with a recipe that merges whole grain goodness, gut-friendly sourdough, and a hidden boost of vegetables.
Why Whole Wheat and Zucchini Make Sense in Bread
A Nutritional Powerhouse
Traditional white rolls may be soft, but they often fall short in terms of nutrition. By using whole wheat flour, you get the full spectrum of nutrients:
- Dietary fiber for digestive health
- B vitamins that support metabolism
- Plant-based protein
- Iron, magnesium, and antioxidants
Add zucchini, and you’re sneaking in moisture, minerals, and a low-calorie veggie boost that blends seamlessly into the dough.
Why Sourdough?
Sourdough is more than just a trend. Thanks to its natural fermentation process, it provides:
- Improved digestibility
- Lower glycemic index
- A tangy depth of flavor
- Natural leavening (if using active starter)
- Potential probiotic benefits
Using sourdough discard? Great—these buns make good use of leftovers, helping reduce waste in your kitchen.
Ingredients Breakdown: What You’ll Need
Here’s what goes into making 12 perfectly fluffy buns:
Main Ingredients
- 1 small zucchini, peeled and chopped (about 1 cup once pureed)
- ¼ cup water (for blending zucchini)
- 2 cups whole wheat flour
- ¾ cup all-purpose flour (or use 100% whole wheat for a denser result)
- ¾ cup sourdough starter discard (or active starter for added lift)
- 1 tablespoon olive oil (or any neutral oil)
- 2 teaspoons instant yeast
- 1 teaspoon salt
- 1 tablespoon melted butter (or more oil for dairy-free option)
Optional Add-ins
- 1 tablespoon honey or maple syrup for slight sweetness
- Fresh or dried herbs (like rosemary, thyme, or basil) for savory flair
- Grated cheese for a richer taste
Step-by-Step Instructions
1. Prepare the Zucchini
Start by peeling and roughly chopping your zucchini. Blend with ¼ cup water in a food processor until completely smooth. The result should be around 1 cup of puree.
Pro Tip: If your zucchini is extra watery, strain it slightly before blending.
2. Mix the Dough
In a large mixing bowl, combine:
- Whole wheat flour
- All-purpose flour
- Instant yeast
- Salt
Whisk to evenly distribute. Then add:
- Zucchini puree
- Sourdough discard
- Olive oil
Mix until a shaggy dough forms.
3. Knead and Rest
Turn the dough onto a lightly floured surface. Knead by hand for 8–10 minutes, or until the dough becomes smooth, elastic, and springs back when touched.
Place in a greased bowl, cover with a cloth, and let it rise in a warm place for 1.5 to 2 hours, or until doubled in size.
4. Shape the Buns
Divide the risen dough into 12 equal portions (about 65–70 grams each). Shape each into a smooth ball and arrange in a greased 9×13″ pan or a round cake pan.
Leave slight gaps between the buns to allow room for expansion.
5. Second Rise
Cover the pan loosely with plastic wrap or a clean towel. Let the buns rise again for 30–45 minutes, or until visibly puffy.
6. Bake to Perfection
Preheat oven to 375°F (190°C). Brush the tops with melted butter or oil. Bake for 20–25 minutes, until golden brown and the internal temp reaches 190°F (88°C).
Optional: Brush with more butter right after baking for a glossy finish.
Serving Ideas: From Breakfast to Dinner
These buns are incredibly versatile. Here’s how you can enjoy them:
- With butter and jam for a rustic breakfast
- As dinner rolls alongside stews, roasts, or soups
- Filled with grilled chicken or turkey for sandwiches
- Toasted with avocado, eggs, or nut butter
- Cut into halves, grilled with garlic butter for a savory snack
They’re also perfect for festive gatherings—try arranging them in a wreath or flower pattern on a platter.
Storage & Meal Prep
Freshness Timeline
- Room temperature: Up to 3 days (airtight container)
- Refrigerated: Up to 7 days
- Frozen: Up to 3 months
Reheating Tips
- Wrap in foil and warm in a 300°F oven for 8–10 minutes
- Microwave individual buns for 15–20 seconds
Pro Tip: For crispier crusts, reheat uncovered in a toaster oven.
Troubleshooting Common Baking Issues
Dough Too Sticky?
Add more flour a tablespoon at a time while kneading. Don’t overdo it—aim for tacky, not dry.
Didn’t Rise Enough?
Make sure your yeast is fresh and active. If using sourdough discard, add a touch more yeast to boost rise.
Too Dense?
Dense buns often result from:
- Not enough kneading
- Cold rising environment
- Too much flour
Use a warm room and knead properly for soft results.
Variations to Try
Why stick with one version? Here are several creative takes:
Sweet Version
- Add cinnamon, raisins, and a touch of honey
- Glaze with vanilla icing after baking
Cheesy Garlic Buns
- Mix shredded cheddar into the dough
- Brush with garlic butter before baking
Herb & Seed Topped
- Sprinkle with sesame or poppy seeds
- Add chopped rosemary or thyme to the dough
Gluten-Free (With Caution)
- Use a gluten-free flour blend and xanthan gum
- Note: Texture may differ slightly

Frequently Asked Questions
Can I make these buns without yeast?
Yes, if using active sourdough starter, you can omit yeast. Just extend the rise times (bulk rise may take 6–8 hours, second rise 1–2 hours).
What other vegetables can I use?
Try:
- Carrots
- Spinach
- Pumpkin
- Sweet potato
- Yellow squash
Each adds its own flavor and nutrition.
Can I make this vegan?
Absolutely. Use olive oil instead of butter, and avoid dairy-based mix-ins. Zucchini keeps the dough soft without eggs.
Is sourdough starter discard safe to use?
Yes—as long as it smells tangy and not foul. It adds depth of flavor and reduces waste.
Can I use a stand mixer?
Definitely. Use the dough hook on medium speed for 6–7 minutes until the dough is smooth.
