Enter sourdough burger buns – a naturally leavened, slightly tangy, wonderfully soft yet sturdy bread that takes your burger experience to a whole new level.

Whether you’re firing up the grill for summer cookouts or preparing a casual dinner at home, these sourdough buns are a must-try addition to your baking repertoire.
What makes this sourdough burger bun recipe truly special is the balance between a soft interior and a slightly crisp exterior.

How to Make Sourdough Burger Buns
Ingredients for Sourdough Burger Buns
Here’s everything you need to create these soft and pillowy Sourdough Hamburger Buns from scratch.
- 1 cup active sourdough starter (100% hydration): This is your natural leavening agent—make sure it’s bubbly and active for the best rise.
- ¾ cup whole milk (warm): Adds richness and softness to the dough.
- ¼ cup water (warm): Helps with dough hydration for a tender crumb.
- 1 large egg: Adds structure and a soft, rich texture.
- 2 tablespoons unsalted butter (softened): Gives the buns a tender and moist interior.
- 2 tablespoons sugar: Feeds the sourdough and balances out the tangy flavor.
- 3¼ cups bread flour (plus more as needed): Provides the structure necessary for a soft, yet sturdy bun.
- 1½ teaspoons salt: Enhances the overall flavor of the buns.
- 1 egg (for egg wash): Gives the buns a beautiful golden shine.
- Sesame seeds (optional): For a classic burger bun look and extra flavor.
Step-by-Step Instructions
This recipe walks you through exactly how to make the best Sourdough Hamburger Buns at home—from feeding your starter to baking the final golden beauties.
1. Activate Your Starter
Before you begin, ensure your sourdough starter is well-fed and bubbly. Feed it 4-6 hours in advance (depending on room temperature) so it’s at peak activity when you mix your dough.
2. Mix the Dough (Morning or Evening)
In a large mixing bowl or stand mixer:
- Whisk together the warm milk, water, egg, sugar, and starter.
- Add the flour and salt. Mix until a shaggy dough forms.
- Knead for 8-10 minutes by hand or 5-7 minutes in a stand mixer until smooth.
- Add softened butter and knead again until fully incorporated and the dough is smooth and elastic.
Pro Tip: The dough should be tacky but not sticky. If it’s too sticky, add a tablespoon of flour at a time.
3. Bulk Fermentation (3-5 hours at room temp)
Transfer dough to a lightly oiled bowl, cover, and let rise at room temperature for 3-5 hours, or until it’s doubled in size. Perform 1-2 stretch-and-folds during this period to build strength in the dough.
4. Cold Fermentation (Optional but Recommended)
Once the dough has risen, cover it tightly and refrigerate overnight for improved flavor and better shaping.
5. Shape the Buns (Next Day)
- Divide the dough into 8 equal pieces (about 100g each).
- Gently shape into balls by tucking the edges under and placing seam-side down on a parchment-lined baking sheet.
- Flatten slightly to form a bun shape.
Chef’s Tip: Place them 2-3 inches apart to give room for rising and even baking.
6. Final Proof (2-3 hours)
Cover the shaped buns with a clean towel and allow them to rise at room temperature until puffy. They won’t double in size, but they should noticeably expand.
7. Egg Wash & Toppings
Preheat oven to 375°F (190°C). Beat one egg with a splash of water and gently brush it over the buns. Sprinkle sesame seeds or everything bagel seasoning if desired.
8. Bake the Buns (18-22 minutes)
Bake for 18-22 minutes or until the tops are deeply golden and the internal temperature reaches about 190°F (88°C). Rotate the tray halfway through for even browning.
9. Cool
Let the buns cool on a wire rack for at least 30 minutes before slicing.
Pro Tips for a Perfect Recipe
- Use a digital scale for consistent bun size and even baking.
- Don’t skip the egg wash—it adds both color and a bit of shine.
- Hydration is key. Don’t overflour the dough or your buns may come out dense.
- Add flavor. Mix in garlic powder, herbs, or shredded cheese for a twist on the classic.
- Store like a pro. Buns stay fresh for 2 days at room temperature or can be frozen for up to 2 months.

FAQs
Can I use discard instead of active sourdough starter?
No, you need an active starter for leavening. Discard lacks the rise needed for fluffy buns.
How long do sourdough burger buns stay fresh?
They stay soft for 2 days at room temperature and up to 2 months in the freezer.
Can I use all-purpose flour instead of bread flour?
Yes, but bread flour provides a better chewy texture. All-purpose works in a pinch.
Why didn’t my buns rise enough?
Your starter may not have been active enough, or your room was too cool for fermentation. Try a longer proof next time.
Can I bake these on the same day without refrigerating overnight?
Yes, just extend the bulk fermentation until the dough has doubled and continue shaping and proofing as usual.
Substitutes & Ingredient Alternatives
- Milk: Use oat, almond, or soy milk to keep it dairy-free.
- Egg: Replace with flax egg (1 tablespoon flax + 3 tablespoons water) for a vegan version.
- Butter: Use olive oil or vegan butter as a substitute.
- Sugar: Swap with honey or maple syrup for a natural sweetener.
- Toppings: Try poppy seeds, caraway, or leave them plain for a rustic look.
