What Makes These Buns Different?
Unlike traditional hamburger buns that rely on instant yeast, this recipe lets your sourdough starter do all the heavy lifting. The slow fermentation creates better flavor, improves texture, and produces a dough that’s easier to digest for many people.
An overnight rest in the refrigerator also helps develop a stronger gluten structure while making the dough easier to handle the next day.
Ingredients
Dough
- ⅔ cup (150g) active sourdough starter
- 1¼ cups (295ml) warm water (100°F / 38°C)
- 2 tablespoons (30ml) olive oil
- 2 tablespoons (42g) honey
- 1 large egg

- 2 teaspoons (13g) table salt

- 1 egg
- 1 teaspoon water
Optional Topping
- Sesame seeds
Ingredient Highlights
Active Sourdough Starter
Your starter should be fully active, bubbly, and recently fed. A healthy starter creates a beautiful rise without any commercial yeast.
Bread Flour
Bread flour gives these buns their signature chew while keeping the inside soft and fluffy.
Honey
Just enough honey adds a touch of sweetness while helping the dough stay moist after baking.
Olive Oil
Oil keeps the crumb tender and prevents the buns from drying out.
Egg
The egg enriches the dough, giving the buns a richer flavor and softer texture.
How to Make Sourdough Burger Buns
Step 1: Mix Everything Together
In a large mixing bowl or stand mixer, combine the sourdough starter, warm water, olive oil, honey, egg, bread flour, and salt until a rough dough forms.
Step 2: Knead the Dough
Knead until the dough becomes smooth, stretchy, and elastic. Add only small amounts of flour if necessary. A slightly sticky dough produces softer buns.
Step 3: First Rise
Place the dough into a lightly greased bowl, cover, and let it rise until nearly doubled. Depending on your kitchen temperature, this usually takes several hours.
Step 4: Overnight Fermentation
Transfer the covered dough to the refrigerator and allow it to ferment overnight. This step builds incredible flavor and improves texture.
Step 5: Shape the Buns
Divide the chilled dough into 10 equal portions (about 100g each).
Roll each piece into a smooth, tight ball by gently pulling the surface underneath to create tension.
Arrange the dough balls on parchment-lined baking trays, leaving space between each bun.
Step 6: Final Rise
Cover loosely and allow the buns to become noticeably puffy. This second proof usually takes between 1 and 2 hours, depending on room temperature.
Step 7: Brush & Bake
Whisk together one egg with one teaspoon of water to make an egg wash.
Lightly brush each bun, then sprinkle sesame seeds on top if desired.
Bake in a 375°F (190°C) oven for approximately 15 minutes, or until the tops turn golden brown and the internal temperature reaches 190–195°F (88–90°C).
Cool completely before slicing.
Pro Tips
- Feed your starter 4–8 hours before mixing the dough.
- Avoid adding too much flour—the dough should feel slightly tacky.
- Create good surface tension while shaping for taller, rounder buns.
- Bake one tray at a time for even browning.
- Let the buns cool before cutting to preserve their soft interior.
Serving Ideas
These homemade buns pair perfectly with:
- Classic cheeseburgers
- Smash burgers
- BBQ pulled pork
- Crispy chicken sandwiches
- Grilled veggie burgers
- Turkey burgers
- Breakfast sandwiches with bacon and eggs
- Pulled beef sandwiches
Storage
Store cooled buns in an airtight container at room temperature for up to 3 days.
For longer storage, slice them first, wrap tightly, and freeze for up to 3 months. Reheat directly from frozen for the best texture.
Frequently Asked Questions
Can I use all-purpose flour?
Yes. Bread flour produces a softer, chewier bun, but all-purpose flour can be used if that’s what you have.
Do I need commercial yeast?
No. An active sourdough starter provides all the natural leavening this recipe needs.
Can I freeze these buns?
Absolutely. Once completely cooled, freeze them in airtight bags for up to three months.
Why is overnight fermentation important?
The slow cold rise develops deeper flavor, improves texture, and makes the dough much easier to shape.
Final Thoughts
These soft sourdough burger buns combine everything you love about homemade bread with the unmistakable flavor of natural fermentation. They’re light, fluffy, slightly tangy, and sturdy enough to hold your favorite burger without falling apart. After one batch, you’ll wonder why you ever settled for store-bought buns.
