Butter Toasted Oat Porridge Sourdough Bread

by - August 29, 2019

I followed the recipe for milk and butter toasted oat porridge sourdough from "Full Proof Baking" with some modifications.  Thank you to Kristen for the idea!

Characteristic of this bread:  The texture is moist, chewy with a hard crust and very mild tangy taste. Usually sourdough starter provides an aromatic flavour to the bread and with addition of toasted butter oat porridge give extra substantial flavour to the taste.

It is advisable to read the notes before baking for any new beginner bakers.

Room temperature in your kitchen plays a very important part in sourdough baking.  It will affect the dough temperature and eventually affect your fermentation time. Warm ambient temperature will contribute to a shorter fermentation time while a cooler room will extend fermentation time.  A longer fermentation duration allows you to have more time to develop the gluten structure . Therefore, high fermentation (warm ambient) doesn’t allow you to work the dough as well.   I learned this from Janet The Soprano

29C – 30C was my kitchen ambient temperature (without air-conditioner)
25C – 27C was my kitchen ambient temperature with the air-conditioner turned on.

I turned on my air-conditioner when I added in levain. My ambient temperature was 25C - 27C during bulk fermentation.  Bulk fermentation is when you let your dough rest after adding in the levain and before you shape your dough.

Usually the best bulk fermentation time that worked for me is 4 - 5 hours at 25C - 27C ambient temperature, provided my starter is healthy and active.  At the end of bulk fermentation, my dough would have increased 40% - 50% in volume. 

A healthy starter is very crucial as advised by Baking with Gina.  It is advisable to feed your starter daily if you want nice big crumb bread that rises nicely and to use the starter (levain) at its peak.

If the mother starter is not strong, the bread dough will not rise much even though the starter is used at its peak.

You may wonder why most of the recipes asked to add salt after autolyze and adding levain.  Salt will tighten the gluten and make it harder to stretch.

Recipe - Butter Toasted Oat Porridge Sourdough Bread

Yields:  1 loaf

Total flour 400g + 40g (levain) = 440g


320g bread flour (I used Japanese high gluten flour) - 80%
50g whole wheat flour - 12.5%
30g rye flour - 7.5%
309g water - 79.32% final hydration 
7g sea salt - 1.75%

80g sourdough starter (100% hydration) - 20%

Oat Porridge:
88g oat porridge - 22%
Toasted 48g rolled oat with 13g butter in a saucepan until slightly golden brown and aromatic, then add in 101g water + 101g fresh milk and simmer till become thick.  Keep aside to cool.

  1. Feed starter - Feed ratio of 1:1:1, keep at room temperature (28C – 30C) and wait until tripled, around 2 – 3 hours.
  2. Autolyse - Mix all flours and water, stir until there is no more dry flour with a spatula.  Or use a stand mixer with paddle attachment for 2-3 minutes at low speed.  Cover and leave for 1 to 2 hours.
  3. Levain - Wet your hand, add 80g levain into the dough and hand mixing until incorporated, about 3 - 4 minutes. Or use a stand mixer with hook attachment and knead for 6 to 8 minutes until window pane stage.  Cover and rest for 30 minutes.
  4. Sea Salt and Oat Porridge-  Sprinkle sea salt on top of the dough, use hand to mix in the salt.  It takes about 5 minutes until it is fully incorporated.  Immediately, add in 88g oat porridge, use your hand to break up the lump if possible and slowly knead in to the dough until well incorporated.  Cover and rest for 30 minutes.
  5. Stretch and Fold - Lightly mist the counter top with water.  Wet your hand and scrapper.  Transfer dough to the counter top.  Pull and fold the four sides, flip over and round the dough.  Return to the same bowl.  Cover and rest for 30 minutes.
  6. Lamination -  Lightly mist the counter top with water and wet your hand.  Pull from centre out to form a rectangle shape. Pick up one edge and fold into the center.  Pick up other edge and fold into the center over first section.  Fold the top down half way.  Fold the bottom up.  Put dough in a new dish (square pyrex dish).  Cover and rest for 30 minutes.
  7. Coil Fold 1 - Fold dough in the dish. Cover and rest for 30 minutes.
  8. Coil Fold 2 - Repeat the same.  Cover and rest for 30 minutes
  9. Coil Fold 3 - Repeat the same.  Cover and rest for 90 minutes. 
  10. Shape - Flour the counter top.  Shape and coat the dough with sesame seeds then transfer to a  slightly flour banetton.  
  11. Proof - Proof at room temperature (RT) for 15 - 20 minutes.  Then retard overnight in the fridge for 12 - 16 hours.
  12. Preheat oven, with the dutch oven at 250C for 30 minutes before baking.
  13. Take bread dough out from the fridge, invert onto a parchment paper and scoring.  Immediately transfer the dough with the parchment paper to your preheated dutch oven.
  14. Lower the temperature to 230C (fan-forced) and bake with cover on for 20 minutes.  Remove the cover and lower the temperature to 220C (fan-forced), continue bake for another 10 - 15 minutes.
  15. Remove bread from oven and dutch oven. Let it cool on rack completely before slicing.
Usually 3 coil folds should be enough.  But, sometimes you may need extra coil fold if your dough is spread and not enough gluten develop.

  1. I am curious why you make so much oatmeal (260 g) (48 g + 13 g + 101 g + 101 g) when you only use 88 g oat porridge in the recipe? I accidentally added the entire amount, and am hopeful I didn't ruin it! Time will tell!

    1. Hi, Thank you for asking and clarification. The liquid evaporated when cooking. You will get less than half of 260g after cooking. Mine just nice around 90g.
      Cheers :)

  2. Hi,

    Does the mixing of porridge interferes the hydration of the dough?

    1. Hi, thanks for asking. The texture of this bread is slightly moist. You can cut down the water if you do not like too moist.

      Cheers :)
