In this post, you’ll learn exactly how to make the best sourdough burger buns, how to know when they’re ready without watching the clock, and how to customize them for your next burger night. Let’s get baking!

Why Make Burger Buns with Sourdough?

Using sourdough for burger buns brings more than just incredible flavor. Sourdough’s long fermentation process helps break down gluten and phytic acid, making it easier to digest. Plus, it gives the buns a deep, nuanced flavor that’s impossible to replicate with store-bought yeast.

You’ll also find that sourdough buns stay fresher longer—thanks to the natural acids in the dough that inhibit mold.

Step-by-Step Instructions for Fluffy Sourdough Buns

1. Mix the Dough

In a stand mixer, combine the sourdough starter, water, melted butter, honey (or maple syrup), flour, salt, and 1 egg. Use the dough hook and knead on medium-low (speed 3–4) for 10 minutes. The dough should become smooth, glossy, and pull away from the sides of the bowl. This process can sometimes take longer, so look for that smooth, glossy sheen on the dough.

💡 Don’t add extra flour too quickly—sourdough dough is meant to be slightly tacky, not dry. The kneading process will help bring the dough together, but once you remove it from the mixer, a little bit of shaping will take away the sticky texture.

2. Bulk Fermentation: Rise Without Watching the Clock

Instead of timing the rise, watch your dough. Cover it with a damp towel or plastic wrap and place in a warm (70–75°F) area. Let it rise until it doubles in size and feels light and “cloud-like.” The surface should be slightly domed and no longer sticky to the touch. To make this happen faster leave it on the counter next to the stove while you cook something else!

On these buns, in my experience, under proofing them on teh bulk ferment is actually totally fine. They’ll make up for it on the second rise.

3. Shape the Buns

Turn the dough out onto a lightly floured surface. Divide into 8 equal portions (90–100g each if you want to weight them to exactness). Pinch the sides of each dough ball underneath and roll gently on the counter to create a smooth, tight top.

⚖️ Use a kitchen scale for even baking and perfectly uniform buns.

4. Second Rise

Place buns on a parchment or silicone-lined baking sheet. Gently press down to flatten slightly. You want the buns to touch so they’ll rise upward instead of outward. Cover with a damp tea towel and let rise again until doubled in size. This rise could take 2–4 hours depending on your kitchen’s temperature. Again, you can speed this up by preheating your oven and leaving the pan of buns to rise on the stovetop.

5. Add Toppings & Bake

Preheat your oven to 350°F. Once the buns are fluffy and puffy, gently brush them with egg wash made with egg yolks and water and sprinkle sesame seeds (or your choice of topping). Bake for 18–22 minutes, or until the tops are golden brown. You can play around with oven temperature here. Sometimes I will preheat my oven to 450, but lower the temps back to 250 once I put the buns into the oven.

📦 How to Store Sourdough Burger Buns

These buns get eaten so quickly in my house, I usually just put them into a cloth bag (I have a tutorial to sew your own here), or into Kraft paper bread bags. Store completely cooled buns in an airtight container at room temperature for up to 3 days. For longer storage:

• Refrigerator: Up to 1 week (reheat to soften).
• Freezer: Freeze buns in a zip-top bag for up to 3 months. Defrost at room temp or pop into a toaster oven.

🌟 To refresh buns before serving, lightly toast or warm in the oven wrapped in foil at 300°F for 10 minutes.

🔄 Sourdough Schedule Tips (For Busy Bakers)

Sourdough works best with flexibility, and I work better just by understanding the visible signs that I’m looking for at each step of the process. But, I realize that not everyone is that experienced or confident. So, if you absolutely need a schedule, here’s a sample timeline you can adapt:

• Morning (8 AM): Feed starter
• Midday (12 PM): Mix and knead dough
• Afternoon (1–5 PM): Bulk ferment until doubled
• Evening (6 PM): Shape and do final rise
• Bake (9 PM or next morning): Bake and enjoy fresh!

You can also refrigerate shaped buns overnight after the second rise and bake them first thing in the morning.

Final Thoughts: Why These Buns Work

This recipe strikes the perfect balance between soft, pillowy texture and sturdy structure—making them perfect for juicy burgers or stacked sandwiches. With simple pantry ingredients and a little patience, you’ll have bakery-quality sourdough buns in your own kitchen.

They’re a staple in our home, and I hope they become one in yours too.
