This is about my favorite sourdough recipe that I’ve created so far.

It’s been a long time coming, but today I’m going to show you exactly how to make this divine loaf of sourdough brioche without any commercial yeast!

But first, let’s go into a little nerdy background info…

Table of Contents:

What is Brioche?

Brioche is an enriched yeasted bread that contains copious amounts of butter and lots of eggs, plus a bit of milk and a smidge of sugar. 

It’s kind of like a cross between a pastry and a bread, with a tender crumb (from the high butter content), and it is heavenly.

Where Does it Come From?

Brioche is actually in a category of French baked goods known as Viennoiserie, which means “things from Vienna.” 

But an Austrian military officer brought this style of baked good to France when he opened a bakery in Paris in the 1830s.

So brioche is kind of Austrian, but commonly known as French.

It’s a bridge between pâtisserie and boulangerie (styles of French baked goods) if you want to get technical.

How to Pronounce Brioche

As far as I can tell, brioche can be pronounced either “bree-ahsh” (with a short “o” sound) or “bree-ohsh” (with a long “o” sound). 

When I’ve listened to videos of native French speakers, it kind of sounds like a blend of a long and short “o” sound.

Any native French speakers can correct me in the comments!

Is it Sweet?

While the dough does contain some sugar, the overall flavor profile isn’t really sweet.

You can brush the outside of the baked loaf with a simple syrup (more on that later) to give it an extra hint of sweetness.

Is Sourdough Brioche Bread Healthy?

This is where opinion really comes into play.

I personally think sourdough brioche bread is healthy because the grains are “pre-digested” by the wild yeast. 

Also, if you use pastured eggs and grass-fed butter and milk, this can be quite nourishing.

Don’t let the amount of butter in the dough scare you off!

Is Challah Bread the Same as Brioche?

No, it’s not quite the same. Challah is very similar to brioche, but challah is actually dairy free and brioche definitely is not. 

Also, challah is of Jewish origin, whereas brioche is considered French.

How to Make Sourdough Brioche Bread

Okay, let’s dive in and I’ll show you how to make it!

A mature sourdough starter that's been fed and is bubbly and active.

Let’s talk sourdough starter for a minute.

Feed your starter about 8-12 hours before mixing together the dough. 

You’ll know that your starter is ready to use when it doubles, is active and bubbly, and passes the float test.

To perform the float test, drop a small piece of your starter in a glass of room temperature water. If it floats, it passes!

If you want more of a sour taste, you can use a starter that has fermented longer and smell sour. For a more mild bread, use your starter when it has just reached peak fermentation. 

For this recipe you’re going to use more starter than you normally would for sourdough bread.

This will help to ensure a high final rise.

Also, since dairy products (e.g. milk and butter) tend to slow down the fermentation process, the extra starter will counteract that.

I have heard of people using sourdough discard to raise bread, but that isn’t how I tested this recipe. Basically, you think of making the bread as feeding your non-active starter. However, this would alter the rise time, and could result in a very sour bread.

NOTE: I keep my sourdough starter at 100% hydration, which means that I feed it equal weights, not volumes, of flour and water.

If you’re having trouble with your starter, make sure to check out my Sourdough Starter Troubleshooting post!


Mixing the Dough

Adding the milk, starter, and eggs to the stand mixer bowl.

Add the wet ingredients to the bowl first:

Place 1/3 cup whole milk, 2 cups (480 grams) of active sourdough starter, and six eggs in the bowl of a stand mixer.

At this point you might be wondering why you thought putting 6 eggs into a bread dough was a good idea.



Adding the flour and sugar to the stand mixer bowl.

Next, it’s time to add the dry ingredients on top!

Add 4 cups (565 grams) of organic all purpose flour and 2 tablespoons (20 grams) of organic cane sugar.


After 5 minutes of kneading.

Knead for 5 minutes on medium low speed using the dough hook attachment, just until the dough comes together.

You could also do this with a Danish dough whisk, but why not use the machine and dirty up fewer dishes?

I personally don’t let my brioche autolyse, because I haven’t felt the need.

But you can always let the dough rest for 30 minutes at this point to give the flour an extra chance to hydrate before adding the salt and butter.


Adding the salt to the sourdough brioche dough.

Add 1 tablespoon (11 grams) of unrefined sea salt.

I use Redmond Real Salt for all of my sourdough bakes.


Slowly adding the butter a tablespoon at a time.

Turn the mixer on and gradually add a cup of softened unsalted butter (yes, this is a RICH dough), one tablespoon at a time.

Don’t add the next tablespoon of butter until the previous one is kneaded in.

By the way, make sure your butter is the proper temperature.

You don’t want it so soft that it’s almost dripping. But you also don’t want it so cold that it won’t mix in easily. 


Kneading the dough for 15 more minutes.

Continue kneading the dough for another 15 minutes after all of the butter is incorporated.

The dough will start to clean the sides of the bowl. 

Doing the windowpane test on the sourdough brioche dough.

You’re looking for the dough to pass the windowpane test.

Stretch it out until you can see light through it.

If the dough breaks and rips apart before you can pull it that thin, it has to be kneaded longer.

Yes, this is a very long knead time. About 25-30 minutes in total. It’s needed since this is an enriched dough.

But keep going until you’ve reached windowpane, or at least very nearly!

I do NOT recommend hand kneading this dough sadly. It could be done, but it would take SO much time.

First Rise (Bulk Fermentation)

The ball of dough placed in a greased bowl.

Grease a large lidded bowl and scrape the dough into it.

A bowl scraper would be handy here (I should really purchase one!).


Putting the lid on the mixing bowl.

Cover with a lid and let the dough rise and ferment at room temperature for 1 hour.

After that hour, place the dough in the fridge for 12 hours.

The dough will puff up some, but it won’t double during those 12 hours in the fridge.

Forming the Sourdough Brioche Loaves

Greasing two loaf pans: one stainless steel, and the other glass.

After the initial rise, grease two loaf pans and set them aside.

NOTE: I much prefer my larger Pyrex loaf pan over this smaller stainless steel loaf tin. 

The glass tends to brown the bottom of the loaf more readily.

It also releases the baked loaf from the pan more easily.

And it’s just a better size for this sourdough brioche loaf.

I should really purchase another one so I don’t have to settle for my stainless steel pan!


Dividing the dough in half.

Transfer the dough to a large plate.

Weigh the entire ball of dough (make sure to “tare” with plate first so you don’t get that weight as well).

Divide that weight by two, and split the dough in half for the two loaves.

I’m going to show you two ways to form these loaves: braided and bun bread style.

Traditionally brioche is formed into a knot instead of a braid, but this style is more practical for home bakers.


Greasing the work surface with avocado oil spray.

Grease your work surface. This is quite a sticky dough.

You can rub some butter on it, or you can spray it with avocado oil spray.


Braiding the brioche sourdough bread.

Braided Loaf

Now it’s time to divide the dough into three equal pieces. 

Divide half of the total weight of the dough into thirds, and weigh out the dough.

For example, if your total dough weight is 1660 grams, half of that would be 830 grams, and a third of that would be 276.66 grams. So each piece should weigh about 276-277 grams.

Am I making sense?

Using greased or wet hands, roll each piece of dough into a log that’s 12 inches long and tapered on one end. I find it’s easiest to squeeze the dough out with your hands instead of rolling it on the counter.

Pinch the far ends of the dough logs together.

Grab the left log and fold it over into the middle. 

Grab the right log and fold it over into the middle.


Pinching the ends of the braid to secure.

Repeat the braiding process until you get to the end. 

Pinch the ends of the logs together to seal.


Tucking the sourdough brioche braid into the greased loaf pan.

Tuck the braid into the greased loaf pan.


Forming the brioche sourdough bun bread.

Bun Bread Loaf

Take the weight of half of the entire dough ball and divide it by 6.

Using the same example as before, half of the entire weight would be 830 grams, so each piece of dough should weigh about 138-139 grams (830 divided by 6 equals 138.33).

Form each piece of dough into a ball by pinching the ends into the middle and rolling it, seam side down, on the counter.

Watch the video below to see this demonstrated.

Stagger the dough balls in the loaf pan. This creates a neat, almost braided look.


Second Rise

The risen loaves of sourdough brioche.

Cover the loaves with a tea towel (you can use greased plastic wrap if you must, but I prefer a tea towel) and allow to rise in a warm spot until they puff up over the sides of the loaf pans.

Since this brioche is risen with sourdough starter, the amount of time it takes to proof adequately varies greatly.

If you have a really warm kitchen, they may puff up in just 2 hours!

Or, if you have a really chilly kitchen, it may take 8 or more hours.

Be patient, and let this sourdough brioche do its thing!

If your kitchen is really cold you may want to cover with a damp towel to prevent the dough from drying out.

Egg Wash

Whisking together an egg plus a tablespoon of water to brush on top of the loaf.

You can achieve that nice, deeply brown, shiny crust that’s so iconic to brioche in a couple of ways.

One simple way is to brush the top of the loaves with an egg wash before baking.

Whisk together one egg and one tablespoon of water until uniform.


Brushing the top of the bun loaf with the egg wash.

Brush the top of the risen loaf with the egg mixture. Get into all the nooks and crannies!

Half an hour before the loaves are done rising, preheat your oven to 375° F (190° C).

Bake the loaves for 35-40 minutes, or until an instant read thermometer inserted in the middle of the loaf registers 190-195° F (88-90° C).

The bake time will vary depending on how hot your oven runs.

The bread should be deeply golden brown.

Here you can see the difference between the bread baked with an egg wash (left) and the one without (right).


Simple Syrup Wash

A jar of vanilla simple syrup.

But here’s another way you can get that dark, shiny crust: Simple Syrup!

To make a vanilla simple syrup (heavenly on this sourdough brioche!), bring 2 tablespoons of water and 2 tablespoons of sugar to a boil.

Remove from heat and stir in 1/4 teaspoon of pure vanilla extra.

Boom. Vanilla simple syrup!


Brushing the warm loaf with the vanilla simple syrup.

Brush that all over the top of the warm, just-from-the-oven loaf.

It’s pretty much the best thing ever.

Do your absolute best to wait at least an hour before slicing into this loaf.

It’s going to be difficult.

Stay strong!

But when you do finally slice into this sourdough brioche, you’ll see why all of that butter and kneading and fermenting were worth it.

So worth it.

How to Eat Sourdough Brioche

Of course you can simply slice, butter, and eat.

But you’re going to die of happiness when you try this toasted with butter and jam.

It’s also makes top-notch cinnamon toast: slather it with butter, sprinkle with a little brown sugar and cinnamon, and do a happy, giddy dance after you take your first bite.

Now some people might say that since there’s so much butter in the dough, you don’t need any on top. To that I say: ridiculous! Butter on top of bread is different than butter in bread.

If you have any leftovers the next day, you can turn it into brioche French toast. It is phenomenal. The soft crumb is perfect.

Leave me a comment and I’ll give you my easy (unofficial) French toast recipe!

Sample Baking Schedule

Here is a sample baking schedule that works well for me.

Day One:

11:30 AM: Feed your sourdough starter and set in a warm spot in your kitchen.

7:30 PM: Mix together the dough. Let sit on the counter for 1 hours, then put it in the fridge overnight for 12 hours.

Day Two:

9:00 AM: Form the loaves and allow to rise at room temperature.

1:00 PM (Or whenever they are done rising): Bake loaves. Allow to cool for 1 hour before slicing.

You could feed your starter Friday morning/afternoon, form the loaves Saturday morning, and bake Saturday afternoon! Then you could have it for brunch on Sunday.


To store, place the sourdough brioche in an airtight container. You can store at room temperature for up to 1 day, and in the refrigerator for up to 5 days. 

For more long-term storage, you can place the cooled loaf in a freezer zipper top bag and place in the freezer for up to a few months. 

Do I need to use organic flour?

While not completely necessary, I highly recommend using organic all purpose flour in this recipe.

You want to treat your wild yeast gently, and adding a bunch of pesticides and bleach can adversely affect it. 

Can You Make Sourdough Brioche Without Sugar?

Technically yes, but I recommend leaving in the 2 tablespoons of sugar. 

That bit of sweetness tends to counterbalance the tang of the sourdough, and it also speeds up fermentation.


BTW, you could form these into hamburger buns as well! Scrumptious!

For the Dough:

  • 1/3 cup whole milk (83 grams)
  • 2 cups active, unfed sourdough starter (480 grams)
  • 6 whole eggs (307 grams)
  • 4 cups organic all-purpose flour (565 grams)
  • 2 tbsp organic cane sugar (20 grams)
  • 1 tbsp unrefined sea salt (11 grams)
  • 1 cup unsalted butter, softened but still a little firm

For the Egg Wash:

  • 1 whole egg
  • 1 tbsp water


  1. In the bowl of a stand mixer, place the milk, sourdough starter, eggs, flour, and sugar. Knead on medium-low using the dough hook for 5 minutes.

  2. With the mixer still running, add the salt.

  3. Add the butter, one tablespoon at a time, waiting until the previous tablespoon has been kneaded in before adding the next one.

  4. Continue to knead the dough for an additional 15-20 minutes, or until it passes the windowpane test. Grab a piece of the dough and stretch it out. If you can see light through it before it tears, it passes!

  5. Scrape the dough into a greased glass bowl. Cover and allow to ferment at room temperature for 1 hour. Place in the refrigerator and allow to chill for 12 hours.

  6. Grease two 9x5-inch glass loaf pans. Set aside.

  7. Divide the dough in 2 and form each half into a loaf. You can braid the loaves or form them into 6 individual buns. I personally recommend braiding them.

  8. Tuck the loaves into the prepared loaf pans. Cover and allow to rise until they puff up over the edges of the pans, about 2-8 hours.

  9. 30 minutes before the loaves are done rising, preheat your oven to 375° F (190° C).

  10. If you'd like to do an egg wash, whisk together the egg and water. Brush on top of the risen loaves.

  11. Bake in preheated oven until the loaves are deeply golden and an instant read thermometer inserted in the center registers 190-195°F (88-90°C), about 35-40 minutes.

  12. Remove loaves to a wire cooling rack. Cool for at least an hour before slicing.

Recipe Notes

  • You can also brush the tops of the loaves with a simple syrup (vanilla is very nice) after they come out of the oven in lieu of an egg wash.
  • To make a vanilla simple syrup, simply bring 2 tablespoons of water and 2 tablespoons of sugar to a boil. Remove from heat and stir in 1/4 teaspoon vanilla extract.

Baked it today turns out amazing! My family loved it!

Why do you put the dough in the refrigerator for 12 hours if it's not going to rise much? There's so many ads on the page and stuff that I can't see if you explain that or not. I've tried reading through but I don't see any explanation of it.

A cold rise in the refrigerator helps with flavor development! It also helps to control the rise so it doesn't over ferment overnight.

I’m wondering.. how long did it take for yours to proof at room temp? And what was your room temp?

yessica munoz

Friday 24th of June 2022

@Erica Kastner, I made it and it turned out great! Mine took about 8 hours but my starter is still fairly young so I’m going to blame it on that, my house was very warm 77 degree’s Fahrenheit or so… one last question.. how do you recommend we store it? Room temp? Or should we freeze it right away?

It was probably about 4-6 hours, and this was in the fall/winter, so my room temperature was on the chilly side.

Hi Erica, thank you for the recipe - and even if the dough did not go up as nicely as described, it is quite a success. I used sweet stiff starter so probably a bit more to experiment with. I would also always use a bit more sugar (even with a sweet stiff starter) - otherwise I think the dough is too much like toast (taste wise) - and I really like the distinct taste of Brioche.

Thank you for putting the recipe online!

best regards - Astrid (Germany)

The lack of rise could be because you used the stiff starter! I use a 100% hydration starter for this recipe! Yes, you can definitely add more sugar if you like that flavor profile!
