My sourdough brioche buns are so easy to make! They’re soft and fluffy, just like store-bought, except with no additives or nasty ingredients. This recipe has helped us replace store-bought buns, and I hope it does the same for you!

Why You’ll Love This Recipe

Safer way to add egg: Unlike many other sourdough brioche recipes, I add my egg in after the bulk ferment not before. This ensures the egg doesn’t go bad in the dough while its bulk ferments.

Simple instructions: I created this recipe to be easy enough for beginners. The steps are simple to follow and understand.

Softest buns: Instead of the common 1:1 ratio, I advise to do a 2:1 ratio. More is explained on the recipe card. This creates the softest buns!

Why Make Hamburger Buns with Sourdough?

When you make brioche buns with sourdough, you get gut benefits from the starter’s cultures. During the bulk ferment, the cultures ferment the other ingredients. This adds even more gut benefits!

My Tips

• Make sure your starter is active! BEFORE YOU GET STARTED: Feed your starter 4-12 hours before starting this recipe.
• Let the dough bulk ferment for 12 hours. It is important to let your dough bulk ferment for the full 12 hours. It should double in size and have air bubbles in it.
• Place the dough in a warm spot to rise. For both the bulk ferment and the second rise after shaping, your dough needs to be at room temperature in a non-drafty place.

Ingredients

• fed sourdough starter: needs to be active and bubbly
• milk: enriches the dough
• raw honey: adds a hint of sweetness
• salt: adds flavor to the dough
• avocado oil (or melted butter): enriches the dough
• all-purpose flour: great flour for buns
• egg yolk: enriches the dough
• optional – melted butter: for brushing after baking

Kitchen Tools You May Need

• sheet pan
• parchment paper (unbleached)

How to Make Sourdough Brioche Buns

Preparing your starter

BEFORE YOU GET STARTED: Feed your starter 4-12 hours before starting this recipe. I recommend feeding it a 2:1 ratio of unbleached flour to filtered water to get the same results as I do when you make this recipe. Example: 1 cup flour + 1/2 cup water. Your starter needs to be active, bubbly, and a thicker consistency to begin this recipe.

Make the Dough

In a large mixing bowl add in fed starter, milk, honey, salt, and avocado oil. Mix until completely combined.

Add in only 1 1/2 cups flour (the other 1/4 cup will be added later with the egg) and stir until a dough forms. Use your hands to bring the dough into a ball if needed. If this isn’t working add 1-2 Tablespoons of extra milk to help but don’t do this if not necessary.

Turn the dough out in the counter and knead for 2-3 minutes( or use an electric mixer with a dough hook)

Bulk ferment

Cover the dough and let it sit at room temperature on the counter or in a turned-off oven/microwave for 12 hours until it doubles in size. See notes for helpful information. Once bulk fermentation is complete your dough should have doubled in size.

Add the egg

Uncover the dough and add in the egg. This will be sticky but knead it into the dough. THEN add the 1/4 cup of flour and knead that into the dough to help with the stickiness. (Do it this way, egg before flour, to prevent large clumps of eggy flour in your bread)

Use your hands to knead until it’s completely incorporated. We do this now so we can still enrich the dough but it doesn’t have to ferment with the raw egg.

How to Shape Sourdough Brioche Buns

Turn the dough out onto the counter and divide into even pieces – 6 (for small buns) or 4 (for larger buns). Add flour to the counter if sticking. 

Shape each piece into a round bun by rolling it on the counter in circular motions to create a ball. Then gently press down on the top to flatten the bottom slightly.

Do this with each piece to shape them all.

Place the buns on a parchment lined sheet pan 2 inches apart. 

Proof the dough & bake

Cover with a dry kitchen towel or seran wrap and let it rise for 3-4 hours at room temperature. (See notes below)

Once the buns are puffy and have proofed for 3-4 hours, preheat the oven to 375 degrees.

Bake for 20-25 minutes or until golden brown and baked all the way through.

Take out of oven and brush with melted butter. Then let cool on a wire rack. Enjoy!

Sample Baking Schedule

• Make the dough: 7pm
• Bulk ferment: 7:10pm to NEXT DAY 7:10am
• Optional: place dough in fridge up to 48 hours after ferment until you’re ready to continue.
• Shape the buns: 7:10am (or when you’re ready to continue the recipe)
• Proof buns: 7:20am to 10:20am or 11:20am
• Bake buns: 10:20am or 11:20am

How to Serve Sourdough Brioche Buns

You can use brioche buns for so many things, just like regular hamburger buns. Here are a few ideas:

• Use them for cheeseburgers, ground chicken burgers, or your favorite burger
• Add pulled pork, pulled chicken, or brisket to them
• Use them as sourdough brioche rolls instead of buns

Notes

What to do if your dough isn’t doubling in size during the bulk ferment and/or 2nd rise:

• If your dough doesn’t look like it’s doing anything halfway through the rises, you need to place it in a slightly warmer area.
• This can be in a turned-off oven with the light on and oven door open, or you can slightly warm the oven to about 75-80 degrees Fahrenheit, then turn it off and place your dough inside with the door shut.
• Never leave the oven on, even on the keep warm setting, with fermenting dough inside. Your dough, for both rises, needs to double.

What to do if your dough won’t double in size even in the warmer place (and your baked good is dense):

• If your dough doesn’t double even in the warmer area, there is a problem with your starter. It is too weak to ferment the dough even in a warm environment.
• To fix this, you will want to leave your starter out on the counter for 2 days and feed it every 12 hours at a 2:1 ratio of unbleached flour to filtered water.
• For example, 1 cup unbleached flour + 1/2 cup filtered (or bottled) water.
• Make sure you’re using unbleached flour and filtered or bottled water to do this. If you don’t, it will affect your starter strength. Reverse osmosis water (or any water that uses salt in the filter) can make the starter weak.
• This will strengthen the cultures in your starter to give you fluffy baked bread and treats. After the 2 days, you can go back to feeding it like usual (once a week if stored in the fridge or once a day if stored on the counter). Be sure to use the 2:1 ratio feeding from here on out.

Sourdough Baking Disclaimer

I regularly feed my sourdough starter a 2:1 ratio of unbleached flour to filtered water, this creates a 50% hydrated starter even when I use discard. If you feed your starter differently, results may vary due to a different hydration which will cause a different consistency. No matter how you feed your starter just ensure it’s a thick consistency when you use it for my recipes even if you’re using discard.

The temperature of my home/kitchen is 70°F. If your kitchen is colder, fermentation could take longer during each phase. If it’s warmer, the phases will be shorter.
