Sourdough Burger Buns

I know it’s a little early to be thinking about BBQ season, but here in Toronto winter has been surprisingly mild. So mild, in fact, that we actually pulled out the grill out a couple weekends ago!

My husband really enjoys BBQ’ing, and one of his specialties is homemade burgers. It’s been my goal to find a homemade burger bun recipe to contribute to the mix, and this is it! I actually started making the yeast version of these awhile back, but now that my sourdough starter is nice and healthy I wanted to convert the recipe to SD. The sourdough adds a subtle tang, and also helps keep these buns fresh a little longer.

These buns are light brioche style, so they’re slightly eggy but not too rich. They’re soft, but sturdy enough to hold hefty fillings without disintegrating into a sloppy mess. I love them lightly toasted so you get the outside crunch plus the soft interior — the best of both worlds!

I’ve broken this recipe into a two day process, though you could probably start these in the morning and have them ready by dinner. In the bulk fermentation step, just let the dough roughly double in size before proceeding.

Sourdough Burger Buns

Makes 8


  • 354 g flour (I use half all purpose, half bread)
  • 110 g heavy cream, at room temperature
  • 110 g water, at room temperature
  • 37 g sugar
  • 1 large egg
  • 8 g salt
  • 35 g unsalted butter, softened
  • 125 g mature liquid sourdough starter
  • Egg wash (1 egg beaten with 1 Tbsp water or milk)
  • Sesame seeds (optional)


  1. Combine all the ingredients except the salt and butter and autolyse (rest) for 1 hour. I find it easiest to combine the wet ingredients in a jug and mix it into the flour using a rubber spatula.
  2. Add salt, and knead dough until gluten is moderately developed. The dough will start out sticky and rough but should gradually come together and feel quite smooth and stretchy. Add butter in two batches, mixing in the first completely before adding the second. Continue kneading until the gluten is very well developed and the dough passes the windowpane test as demonstrated here. The dough should be smooth and supple (and quite lovely to handle!). This will take quite some time, especially if done by hand. Consider it your arm workout for the day!
  3. Transfer dough to a clean bowl, cover with plastic, and allow to rise at room temperature for 2 hours. Refrigerate overnight.
  4. The next day, turn the dough out onto a lightly floured surface. Divide into 8 equal parts, and roughly shape as balls. Cover with oiled plastic and allow to rest for 1 hour.
  5. Prepare a baking sheet lined with parchment or a Silpat. When the hour is up, reshape each portion into a tight ball and flatten gently into a disc. Arrange on baking sheet at least 2 inches apart. Cover again with oiled plastic and allow to rise again at room temperature until puffy and nearly doubled. (I needed to run some errands so I put the dough in a cool part of the house and let it go for 5 hours. In a warmer room I suspect it would take 3-4 hours.)
  6. When ready to bake, preheat the oven to 400F and set an old cookie sheet on the floor of the oven. Prepare the egg wash. Brush each bun with the egg wash, followed by a sprinkling of sesame seeds.
    Transfer the buns to the preheated oven and immediately pour a cup of hot water into the baking sheet on the bottom of the oven (be careful! Wear oven mitts and use a long-spouted kettle if possible). Bake buns for 18-20 minutes or until rolls are nicely browned on top, rotating the sheet halfway through baking. Cool on a rack completely.
