Blueberry Swirl Sourdough Brioche Bread Recipe

You know, sometimes you need a bit of a pick-me-up. You love blueberries. You love anything baked and, like me, you love butter. Mmmh… Butter! You could make a cake, but you just had cake yesterday, so what are you going to do? The answer is, of course, my recipe for a blueberry swirl sourdough brioche bread.

Last week I baked a sourdough bread with blueberries and lemon. You know the kind with a chewy crumb and a crispy crust. That was a super delicious bread, but this time we are going in the absolutely opposite side of bread types. The Fluffy McFluffface of fluffy breads. Dough so enriched that is should be called millionaire’s brioche. Oh my freakin’ Gawd…

The history of brioche bread

Wikipedia writes:

The first recorded use of the word in French dates from 1404. It is attested in 1611 in Cotgrave’s A Dictionarie of the French and English Tongues, where it is described as “a rowle, or bunne, of spiced bread” and its origin given as Norman.

It’s a bread that’s developed over the years from a bread that was used in the Catholic church called pain bénit. Over the years it became increasingly enriched with ingredients as egg, butter, sugar and milk.

Historically, two types of brioche were produced:

  • Rich man’s brioche (flour: butter ratio, 3:2)
  • Pain brioche (flour: butter ratio, 4:1)

The addition of butter to this bread helps mask the taste of yeast or sourdough starter in the bread, so there’s absolutely no tang.

The formula in this blueberry swirl sourdough brioche bread recipe

The levain in this recipe is a pretty standard levain. It’s made at the proportion 1:1:1 (one part starter, one part flour and one part water) to get ready as quickly as possible. We’re using it at the time it’s doubled, but if you need it to really pack a punch you should use it when it’s at its peak.

This bread has an exuberant amount of butter. The total flour in the bread is 525g (450g plus 75g in the starter), but the amount of butter is 375g.

A rich man’s brioche has the proportion of 3:2 of flour to butter, so that would make the amount of butter 350g (525 * 2 / 3), so this has an extra 25g added for the love of butter.

As always you can play around with the formula in my Bread Calculator. Notice that the measurement of the hydration is off, as there are really no way to gauge the hydration is a highly enriched dough.

The feel of the dough seems to be in the 60’s range. Slighly tacky, but not sticky.

Conclusion on this blueberry swirl sourdough brioche bread recipe

So this is bread is something very special. It is probably the tastiest bread I have ever baked. It isn’t a regular bread though. One that you would eat with meat, cheese or vegetables. That’s a good thing, or else we wouldn’t eat anything else in my house.

The crust is flaky and deeply caramelized, which makes it insanely satisfying to eat. The crumb is soft with small holes scattered throughout.

  • 450 g bread flour
  • 4 eggs
  • 150 g levain
  • 60 g milk
  • 30 g sugar
  • 15 g sea salt
  • 375 g butter

Blueberry Jam

  • 250 g blueberries
  • 125 g sugar
  • 3 tablespoon cornstarch
  • 50 g water

Egg wash

  • 1 egg
  • 1 tablespoon milk


Make levain – morning

  • Add 50g sourdough starter, 50g bread flour and 50g water to a see-through container with straight sides. Mix well.
  • Leave to ferment, covered in a warm place. Once it has grown to the double the size you need to mix the dough.

Make the blueberry jam – morning

  • Put 250g blueberries in a small pot. Add 125g sugar, 3 tbsps cornstarch and 50g water.
  • Mix to combine everything. Bring the mixture to a boil.
  • Let simmer for about 10 minutes. Turn off the heat and let the mixture sit in the pan for about 15 minutes to a cool a bit.
  • Add the mixture to a bowl and cover with aluminium foil. Let cool in the refrigerator until needed.

Mix the dough – around noon

  • Add 450g bread flour, 150g levain, 4 eggs, 30g sugar, 15g salt and 60g milk to a bowl.
  • Put your index and long finger in the middle of the dough and start moving it in circles, for each revolution make the circle a little bigger so you get more and more flour into the fluids,.
  • Once that gets difficult, grab the back of the dough with your hand, stretch it up and in over the dough, turn the bowl a bit and repeat until all the flour is completely hydrated.
  • Leave the dough to rest for 30 minutes under a damp dish towel.

Bulk fermentation – around 12:30/12.30 p.m

  • Perform four sets of stretch and folds spaced out by 30 minutes.
  • After the fourth set of stretch and folds, perform a windowpane test to check the gluten development. If it doesn't pass perform one more stretch and fold and let the dough rest for 30 minutes and test again.
  • Once the windowpane passes, take the butter out of the refrigerator and cube it. Rest the dough for 30 minutes.
  • Now it's time to add the butter. Put a small handful of cubes on the dough and start to push it and massage it into the dough. Keep going until you cannot feel any lumps anymore. Then add another handful. Repeat until you have added all the butter.
  • Then let the dough ferment until it has expanded by 30-50% in volume.
  • Put the dough in the refrigerator for a minimum of 2 hours, a maximum of 48.

Shape and final proof

  • Flour your work surface liberally. Dump the dough out and tease it into a rectangle.
  • Roll it out so that it's about the width of your pan minus 1.5cm/½". Roll it pretty thinly so that the bread has to rolled several times to be one round loaf.
  • Apply the blueberry jam on the dough. At the end you will start rolling you can go to the edge, but at the other end you should leave about 3cm/1" room without any jam. On the sides you should leave about 1.5cm/½" room without jam.
  • Then roll up the dough pretty tightly.
  • After you have a roll of dough, fold the ends underneath the bottom to seal the jam inside.
  • Grease your tin liberally with butter or baking spray and place the dough in the tin.
  • Then cover the tin with a damp dish towel and let it proof until it has doubled in size.

Bake the bread

  • Pre-heat the oven to 200ºC/390ºF/Gas mark 6.
  • Beat 1 egg with 1 tbsp milk.
  • Brush the bread lightly with the egg wash.
  • Bake for about 60 minutes or until the inner temperature reaches 98°C/208ºF.
  • If the bread starts to get too brown during baking cover it with a piece of aluminum foil.
  • Once the bread is out of the oven, let it cool for 10 minutes and then take it out of the tin and let cool completely.

    Thanks for the recipe! I’m trying this (without the jam) and am currently waiting for my loaf to finish the final proof. About how long should the bulk ferment take? What about the final proof? Thanks in advance!

    • It depends on a lot of factors, so go by it growing to the correct size. Bulk can be anywhere from 2 to 8 hours 🙂

    How did you incorporate the butter by “massaging “ it into an already formed gluten network?
    I managed only 250 g into a 900 g flour recipe…
    It starts to melt if you don’t want to get pockets of butter inside.

    • Have a look at how I do it in the video. It’s one of those things that are hard to put into words 🙂

    The blueberry jam says 3tsp of cornstarch in the ingredient list, but 3tbsp in the instruction text. Which is correct, please?

    I used my stand mixer to work in the butter. I may have overkneaded it – by the time all the butter was in, it had more of the texture of cake batter than bread dough. We’ll see how it rises.

    • While working it in by hand is a lot of work, you can never overwork the dough 🙂 I hope it turns out.
