These soft, fluffy, flavorful buns will be the star of any hamburger meal.

A light egg wash gives these buns a flaky golden top, perfect for classic sesame seeds. Once you try this sourdough bun recipe, you’ll never go back to store bought burger buns!

Soft Hamburger Bun Recipe with Sourdough Starter

Making soft burger buns is all about using the right ingredients. Unlike regular sourdough bread, you will need to use eggs, milk and butter in this recipe. These are the ingredients that keep the buns light and fluffy! Here’s everything you need to make the best soft hamburger buns:

  • Fed, active, bubbly Sourdough Starter: I like to use my Sprouted Rye Sourdough Starter in this bun recipe. If you do not already have a starter, you’ll need to start this 7 days before baking, or 2 days before baking if you use our quick recipe option.
  • Flour: I use organic bread flour or organic unbleached all-purpose, both work well. 
  • Milk: I like to use whole milk for these buns, but plant based milks work well in this recipe too.
  • Butter: I use grass-fed organic butter, but any vegan butter also works.
  • Egg: I only use pasture raised organic eggs, and make sure you whisk your egg well before adding it to the dough. If you are vegan, I’ve used Bob’s Red Mill Egg Replacer and it worked well.
  • Salt: Unrefined sea salt, please! Just make sure your sea salt is unrefined and free from anti-caking agents. 
  • Spray Bottle Filled with Fresh Water: This is a must-have for stretching and folding the dough. (see the section below) 
  • Parchment Paper: Baking these sourdough buns on parchment paper is a must

Easy Sourdough Burger Buns

The hardest step when making these burger buns is the stretching and folding, and the shaping. It takes patience and a gentle touch, but is not difficult. I find that shaping burger buns is easier than shaping a sourdough boule. Just follow the directions in the recipe card below, and you shouldn’t have any problems!

Large Hamburger Buns

It’s easy to make large hamburger buns at home. If you want larger buns, you just need to divide the dough into less pieces. This recipe gives you six large buns, perfect for a big juicy burger. If you need them even bigger though, you can divide the dough into five pieces instead of six. For smaller buns, such as buns you use to make sliders, Divide the dough into 8 or 9 pieces before shaping into buns.

Sourdough Buns Digestibility

Sourdough is the oldest form of bread. Experts say that the bread originated in Egypt long ago… as in 1,500 BC. Since commercial yeasts were obviously not available back then, bread products had to be naturally leavened using wild yeats. 

Wild yeasts are “captured” in a sourdough starter along with flavor developing microorganisms, like lactic acid bacteria. When I say “captured” I mean they come from the flour you use to make it. The wild yeats are significantly more acid-tolerant than packages of baker’s yeast. So the yeasts in sourdough are still very active and able to produce carbon dioxide to make the bread rise even when they’re in the presence of acid-producing bacteria. Visit our sourdough starter blog to learn more about the microbiology of sourdough starters. 

Since sourdough ferments during a longer rise time than traditional bread, it’s much easier to digest and more flavorful. The flavor comes from the wild yeasts and bacteria metabolizing the sugars in the dough during the long rise times and producing acids as byproducts. This is also why the bread is easier to digest! Essentially the microorganisms do some of the digesting for you in this sourdough bread recipe.

Sourdough Nutrition

Sourdough bread is made out of flour, just like regular bread. However, the fermentation process makes the nutritional components of the flour more bioavailable. Lactic acid bacteria in sourdough starters are able to reduce phytic acid, the compound that can prevent nutrient absorption in regular bread. Without the phytic acid, binding to the minerals, you can absorb more potassium, phosphate, magnesium, folate, and zinc from the bread. Those amazing little lactic acid bacteria also produce antioxidant compounds (postbiotics) and SCFAs (short-chain fatty acids) during the fermentation process. Aren’t lactic acid bacteria awesome?!

Ingredients

Scale

Buns

  • 100 grams Sourdough Starter
  • 300 grams Warm Milk
  • 1 Egg, beaten
  • 450 grams Bread Flour
  • 10 grams sea salt
  • 2 Tablespoons Butter, grated
  • 20 grams sugar
  • 2 teaspoons active dry yeast (optional)****

Egg Wash

  • 1 Tablespoon Milk
  • 1 egg beaten
  • Sesame Seeds

Instructions

  1. In a large bowl, combine all of the bun ingredients
  2. Knead the ingredients together until a uniform dough ball forms.
  3. Cover the bowl with a towel and rest the dough for 30  minutes.
  4. First Stretch and Fold: Turn the dough out onto a lightly floured counter top. Scrape out the bowl and rinse the inside of the bowl really well. Dry the bowl and run the inside lightly with oil.
  5. Stretch and fold the dough. Stretch the top of the dough over the bottom, side over side, and bottom over top. Place the dough back in the bowl with the seam side down. Let the dough rest for 2 hours. It should puff up quite a lot.
  6. Second Stretch and Fold: Turn the dough out onto a lightly floured counter top so that the wet side is up.
  7. Stretch and fold the dough. Stretch the top of the dough over the bottom, side over side, and bottom over top. Place the dough back in the oiled bowl with the seam side down. Let the dough rest for 1 hour.
  8. Next, sprinkle some flour on the surface of your counter. Remove the dough from the bowl and place it on the floured surface with the wet side up.
  9. Stretch the dough into a rectangle that’s a little bigger than a sheet of paper. Be gentle with the dough! You don’t want to flatten it. Just lightly pull the sides.
  10. Using a knife or a pizza cutter, cut the dough into 6 even squares. (for smaller buns cut into 7 or 8 squares)
  11. Line a baking sheet with parchment paper and sprinkle flour on top of the parchment paper.
  12. Grab a single square, and fold in the corners of the dough over each other, forming a round dough ball. Place the dough ball on the floured parchment paper. Repeat until all the dough has been shaped.
  13. Lightly press down on the tops of the dough balls to slightly flatten them.
  14. Lightly sprinkle the top of the dough balls with flour. Cover the dough balls with a towel and let them rise for 1 hour at room temperature.
  15. Preheat your oven to 400 degrees F. (Note: If you feel that your oven runs on the hotter side, you can bake at 375 F)
  16. Whisk together the egg and milk for the egg wash.
  17. Baste the buns with the egg wash. Leave them plain or sprinkle sesame seeds on top.
  18. Bake for 15 minutes. Rotate the pan and bake for another 10 minutes if needed until the buns are golden brown on top.
  19. Remove and allow to cool for 30 minutes.

Notes

**** If you want to speed up the process, you can add a packet of active dry yeast to the dough. If you do the dough will only take 90 minutes total to rise, before you can shape and bake.

You can freeze these buns for extended storage.

Hi Kaitlynn

I’m so excited about this recipe. Busy making the dough as I type. I was curious if adding steam to the oven is necessary, as with other sourdough bread? or possibly putting a lid on the buns for the first 15 min bake?

Steam isn’t necessary, but I am located in a very humid climate, so it may be different for you. If you want to add a little steam or humidity, you can throw a few ice cubes in the bottom of the oven with the first 15-minute bake.
