Sourdough Burger Buns

I've been trying to get sourdough burger buns right for a while now. Plenty of versions before this one, most of them fine, none of them what I actually wanted. This is the one that finally got there.

These are brioche style, which means eggs and butter worked into the dough until it's rich, fluffy, and a little sweet, not just a sourdough loaf shaped into a bun. They start with a proper levain build the night before, get their rise from real fermentation instead of commercial yeast, and still hold together well enough to survive a burger without falling apart. This recipe is adapted from and inspired by Sourdough Brandon, whose original version is worth checking out for the full step-by-step photos.

A Reason Beyond the Bread

My girlfriend is gluten intolerant, and sourdough is one of the few breads she can actually eat without issue. The long fermentation breaks things down in a way that seems to make it easier on her system, even though it's still wheat flour at the end of the day. That's part of why I keep coming back to sourdough baking instead of treating it like a novelty. It's not just a technique I like, it's bread she can actually sit down and enjoy.

Rich Enough to Need Patience

A standard sourdough dough is flour, water, salt, and starter. This one adds eggs, whole milk, and a full stick of butter worked in a tablespoon at a time, and that changes everything about how the dough behaves. It takes longer to build strength, longer to proof, and needs an overnight cold rest before shaping. None of that is optional if you want the texture right. The payoff is a bun that's soft enough to press between two fingers and still sturdy enough to hold a burger without falling apart halfway through.

Lukas's Note

Surface tension is everything. When you shape them, you want to feel resistance — the dough should feel taut under your palm. If it feels slack, you haven't built enough tension and they'll spread.

  • 10g sea salt
  • 27g granulated sugar
  • 3 large eggs (165g)
  • 133g whole milk
  • Levain (above), or 162g active sourdough starter
  • 113g unsalted butter, softened (1 stick)
  • 1 egg, beaten, for egg wash
  • sesame seeds, optional, for topping

Equipment

  • Baking scale
  • Stand mixer with dough hook
  • Bench scraper
  • 2 half sheet pans
  • Pastry brush
  • Folding proofer (optional)
Instructions

Build the Levain

  1. Mix. Stir the levain ingredients together in a clean jar until the flour is fully hydrated.
  2. Ferment. Cover and set in a warm spot (75–80°F) for 4–5 hours, until doubled and bubbly. Or skip this and use 162g of active starter directly.

Mix the Dough

  1. Combine. In a stand mixer with the dough hook, mix the flour, salt, sugar, eggs, milk, and all the levain on medium-low until the flour is just incorporated. Cover and rest 10 minutes to hydrate fully.
  2. Add the butter. Mix on medium speed, then add the softened butter one tablespoon at a time, waiting about 30 seconds between each piece until fully worked in.
  3. Develop. Mix 7–10 minutes, until the dough is tacky but strong and passes the windowpane test.

Ferment and Proof

  1. Bulk ferment. Transfer to a large bowl, cover, and let rise in a warm spot (75–80°F) for about 5 hours, until doubled, airy, and domed.
  2. Cold proof. Refrigerate overnight, up to 2 days.

Shape and Bake

  1. Divide. Punch down the dough, weigh it, and divide into 10 equal portions (roughly 105–110g each).
  2. Shape. Roll each portion into a tight ball using the friction of a clean, lightly floured work surface.
  3. Second proof. Arrange 5 buns per lined baking sheet, cover, and proof in a warm spot 4–5 hours, until doubled and wobbly when the pan is shaken.
  4. Egg wash. Preheat oven to 375°F with racks in the upper and lower thirds. Brush the tops with beaten egg and sprinkle with sesame seeds if using.
  5. Bake. Bake 12 minutes, rotate and swap the pans, then bake another 10–12 minutes, until deep golden brown. Cool completely on a wire rack before slicing.

Recipe Notes
  1. Your starter needs to be active. Doubled and bubbly before you start, whether you build a levain or use starter directly.
  2. The cold proof is flexible. It can stretch up to 2 days if your schedule doesn't line up, it won't hurt the dough.
  3. Surface tension matters when shaping. If the dough feels slack instead of taut under your palm, it'll spread instead of holding its shape in the oven.
