  • Total Time: 20 hrs 10 mins
  • Yield: 2 loaves 1x



For the dough

  • 83g whole milk
  • 480g active sourdough starter
  • 6 whole eggs
  • 565g organic all-purpose flour
  • 20g organic cane sugar
  • 1 tbsp. unrefined sea salt
  • 1 cup unsalted butter (softened but firm)

For the egg wash

  • 1 whole egg
  • 1 tbsp. water


  1. Place milk, sourdough starter, eggs, flour, and sugar into a large bowl or stand mixer bowl. Knead on medium-low using the dough hook for 5 minutes.
  2. Add salt while the mixer continues to spin.
  3. Add butter, one tablespoon at a time. Wait until each tablespoon has been kneaded before adding the next spoonful of butter.
  4. Let the mixer spin for 15-20 minutes, or until it passes the windowpane test. The windowpane test is essentially when you grab a piece of dough and stretch it out. If you can see light piercing through the dough just before it tears, it’s ready!
  5. Scrape the dough into a pre-greased glass bowl, then cover it with plastic wrap and allow this to ferment at room temperature for 1 hour. Place this in the refrigerator for 12 hours.
  6. Grease two 9×5-inch glass loaf pans then set them aside.
  7. Divide the dough into 2 separate balls, and form each dough ball into a loaf. You can braid the loaves, or create 6 individual buns for an easier finish.
  8. Place the loaves into the prepped loaf pans, then cover and allow them to rise, until they’ve almost doubled in size (2-8 hours).
  9. Meanwhile, preheat your oven to 375 degrees Fahrenheit.
  10. Whisk together egg and water, then brush this on top of the puffed-up loaves.
  11. Bake the loaf of sourdough brioche in the preheated oven, until they turn a wonderful golden brown. This should take around 35-40 minutes.
  12. Remove the loaf and transfer it to a wire cooling rack. Let this cool for an hour before slicing.
