Pale Ale & Potato Sourdough Burger Buns

Jump to recipe

If you have already mastered the sourdough burger buns, consider this recipe as an advancement! An overnight preferment made using the sourdough starter, flour and pale ale is added to the dough to give extra flavor to already delicious buns. Boiled potato brings in extra starch that makes the crumb extra soft without the addition of milk or eggs.

I am a massive fan of sourdough bread with potato (spuds) and beer. If you are too, then check my ‘Ale & Potato Sourdough Bread‘ recipe. The smell of these buns reminded me of that bread.


A preferment is something that you should embrace if you are a baking enthusiast. It can be used to flavor your baked goods. You make a slurry with flour and whatever the liquid/flavor you want to infuse with and then let the yeast thrive in that. The secret is you use only a very little yeast or sourdough starter to make a preferment, as they will multiply during the fermentation period. This can be used to introduce (sour)flavor to bread without using an actual sourdough starter.

Feel free to use your favorite pale ale and experiment with different flavors (intensity). You might even be able to distinguish different buns made with different beers. Some pale ales are more pungent than the others (the hop is more pronounced in some) and it comes through in the baked burger bun.

sourdough starter

Refresh your starter as usual and make a 100% hydrated starter and use 40g of that to make the preferment

Pour pale ale to a container and let it settle before measuring the correct amount

The mature preferment will look bubbly and expanded just like your ripe sourdough starter. It will have a strong vinegary (acidic) smell to it.

mashed potatoes

Either boil your potatoes or microwave until very soft. Peel and mash to a fine paste, using a masher or a spoon/fork.


Use a mild honey. You can of course use a bit of sugar (white or brown) instead.


Fat helps make the crumb soft and silky, by lubricating the gluten bonds. Use either butter, bacon fat or some vegetable oil. Avoid using pungent olive oils if you want the flavor of ale to come through.

make the dough

Add all ingredients in a bowl of a stand mixer(or mix by hand) except water. Start mixing and add water gradually until a soft dough is formed. Cover and leave to rest for 10-15 minutes and continue to knead on medium speed for 2-3 minutes. Dough will start to release from sides.

finish off kneading

Bring the dough onto a table, wet your hands and perform slap and folds to finish off kneading. Do this until you get a considerably smooth dough.

ready to bulk

Place the smooth dough in a lightly greased bowl, cover loosely and leave in a warm place to bulk or until almost doubled in size. May take about 3-4 hours

punch down

Punch the dough down, and round it up into a tight ball again. Place in an air tight container and refrigerate for serval hours for the slow fermentation. Anywhere from 12 to 24 hours

bring the dough out

When you are ready to make the rolls, bring the dough out and let it sit for about 15-30 minutes


Divide the dough into 8 equal pieces


Shape the burger buns. Watch this video to see how I do it. The smoother the surface, the better and shinier they will look once baked.

place on a tray

Place the shaped rolls on a parchment lined tray. Flatten each dough slightly with your palm. Cover loosely and let these proof for about 2-3 hours or until almost doubled in size like shown in the next picture

proofed rolls

They not only grow sideways but upwards too. Do a poke test to make sure if they are proofed.

Pre-heat the oven to 425°F or 220°C.


When the oven is ready, egg wash and sprinkle the buns and bake in the preheated oven for 15-20 minutes. Reduce temperature to 400°F and bake for a further 5-8 minutes until evenly golden brown all around

Use steam if you like a chewier skin.

baked rolls

Leave the baked rolls to cool before storing away or using.

  1. I just found your site and I’m so impressed with your sourdough work. I can’t wait to recreate a bunch of them! I have a booth at a Farmers Market in Texas and I make 42 loaves of Japanese Milk Bread and variations of it
    to sell weekly. I’m always searching for new things, and I believe I just hit the mother lode!
    Thanks and Happy New Year,

      All the best!

  2. Hello, very nice recipe! Can wait to try it. I have a question about the preferment do you leave it at room temperature or in the fridge?
    Thank you
