Want to make your own sourdough bread? Baking fresh bread is one of the most rewarding experiences a cook can have. Making your own sourdough takes this experience to the next level, as you get to control every part of the process, using the simplest of ingredients – just flour and water.

Check out our sourdough starter recipe then turn it into homemade sourdough bread with the following expert tips from our sourdough baker. Hopefully your starter is raring to go and you’ve got pats of salted butter on ice – let’s make bread!

Got any other sourdough starter leftover? Use it to make our delicious sourdough pancakes or sourdough brownies.

How to make a sourdough levain

Mixing some sourdough starter, flour and water together, with a spoon or by hand, creates a ‘young levain’ and simply involves taking some of the old, strong starter – that is likely very sour – to start working on a new batch of flour and water. This utilises the strong colony of yeast and retains a little bit of its sourness while still keeping the natural sweet flavour of the flour.

My basic recipe is:

sourdough starter 40g

strong white bread flour 15g

rye flour 15g

water 30ml, warm to the touch

Once combined, leave at room temperature, covered with a clean tea towel. Do this the night before you want to make your bread, so that in the morning the levain is beautifully frothy and at full strength. At this point it’s well worth feeding your remaining starter, too, as you’ve likely reduced it substantially to make the levain.

Spelt sourdough recipe

This is when the magic of sourdough happens. The shaggy, lumpy dough – which is created by combining the below ingredients – will soon become a smooth, shiny, stretchy, buoyant mass. Again, time and patience are key. This is the highest maintenance part of baking sourdough: you need to nurture and encourage the dough with your hands. Having said that, sourdough is known as a ‘no-knead’ bread – when left to ferment, the dough’s gluten bonds will align themselves.

This sourdough loaf is one of my favourites to bake. Spelt is an ancient grain that has been cultivated since around 5,000 BC but over time has been replaced by high-yielding ‘strong’ wheat varieties. Spelt contains less gluten but has a much stronger flavour and is more nutritious than normal wheat.

Sourdough loaf


  • 100g levain (recipe above)
  • 380ml water, warm to the touch
  • 400g strong white bread flour
  • 100g wholewheat spelt flour
  • 12g fine sea salt


  • STEP 1
    Sourdough, part 2

    Start by putting the levain into a large mixing bowl and then pour in the warm water. Mix well with your fingers to distribute the levain, then add the flours and mix really well with your hands. You will learn most about the different stages of your bread by getting your hands on the dough. Even professional bakers who mix dough in 50kg dough mixers, reach in and touch, stretch and feel the dough. Open up your fingers and use your hands like whisks to really mix the flour, levain and water together well. Leave this to rest for between 20 minutes and 1 hour, covering the bowl with a clean tea towel. This stage is called the autolyse and comes from the Greek for ‘self-digestion’. This is why sourdough doesn’t have to be kneaded, as the gluten structure forms itself here, doing all of the hard work. If you’re particularly short on time, even a 15-minute rest will make a difference.

  • STEP 2

    Tip in the salt (adding it after the autolyse ensures the dough develops better elasticity) and, with wet hands, mix the dough really well. Breaking the gluten bonds now will allow them to reform even stronger.

  • STEP 3

    The next step is called the bulk fermentation. Leave the dough covered with the tea towel and, every 45 minutes, ‘stretch and fold’ the dough. Wet your hands, take one side of the dough, stretch it up (being careful not to tear the dough) and fold it over on top of itself. Turn the bowl 90 degrees and repeat, doing this six to eight times. The dough will ‘tighten’ and become less slack. Repeat this every 45 minutes for 3-4 hours (so 4-5 times in total). Every time the dough is turned it should have more air bubbles and also, toward the end, feel noticeably lighter.

  • STEP 4

    Next is the bench rest. This is when the dough can be encouraged into a regular shape, creating tension so that it has the strength to stay ‘bread shaped’ when baked, as opposed to flattening into a pancake. Flour a clean worksurface really well and tip out the dough. Using a dough scraper, fold the dough up and over on itself, similar to the stretch and fold method but just folding this time. Do this 4-6 times, and again the dough will tighten and hold its shape better. Add more flour to the worksurface if the bread is sticking.
    The dough should be relatively round now, so leave it to rest for 10-15 minutes – expect it to flatten a little.

Shaping the dough

Start by flouring the banneton or proving basket. In this method I use a cold proving technique, which means putting the loaf into the fridge overnight or for several hours. This increases flavour, as the acid production is still happening but with little gas production, meaning a more stable loaf. The cold will also make the loaf set its shape in the banneton, giving a headstart for a beautiful plump loaf once baked.

Flour the top of the loaf, then flip it out upside-down onto a worksurface. Lightly shape the loaf into a rough rectangle and fold the edge furthest from you up and over the middle. Do the same with the left-hand edge, the right-hand edge and the edge nearest to you. Work quite quickly to keep the shape of the loaf. Lift up and put straight back into the banneton, folds facing up, and into the fridge to chill. Again, if you’re short on time, just 1 hour will help the dough keep its shape better.

Baking the sourdough

Heat the oven to as hot as it will go and put a lidded cast-iron pot in while it heats, for around 45 minutes. This will help to recreate the conditions of a baker’s oven. In the first part of cooking, bread needs steam because a moist environment means bread will rise to its fullest and prevents the crust from forming on the loaf, so it can keep rising. Cooking the bread inside a lidded cast-iron pot for the first part of cooking traps the naturally produced steam.

The faster the loaf comes out of its banneton, is scored and in the oven, the better. So get yourself well prepared by having a clean chopping board or cake slider (in baking terms this is called a peel) in front of you, so you can score the loaf on this and then carefully slide it into the pot.

Also have your scissors/knife/lame (blade) close to hand. The reason to score a loaf is to direct it where and how to rise. As the gasses expand inside the loaf, they will tear the outer structure – without scoring, the loaf will often tear on the side or near the bottom, which will ruin its look.

Have a good pair of oven gloves and a bowl of polenta to hand. Scattering polenta on the chopping board allows the loaf to slide off easily into the pot.

When fully heated, remove the pot from the oven and take off the lid. Turn the oven down to 260C/fan 240C/gas 9. Remove the loaf from the fridge and scatter polenta all over the chopping board, the bottom of the pot and the loaf. Turn the loaf out onto the chopping board (it may take a little coaxing) and score the top – I often just cut a square. Slide the loaf into the pot, put the lid on and return to the oven for 20 minutes.

Remove the pot from the oven and take off the lid. Return to the oven without the lid for another 20 minutes. Remove from the oven again and tip out on to a wire rack to cool. Then enjoy your delicious sourdough creation, slathered with butter.

Keep trying!

Bread baking is a hugely rewarding process, but it can be quite unforgiving. Even as a professional baker, baking 250 sourdough loaves in a day, it can be unpredictable – there are many variables and factors that can influence a loaf. If your loaves aren’t as good as you’d hoped, keep trying. The more you bake, the more success you will have. Once you’ve baked the loaf of your dreams, harnessing the power of flour, water and salt, you’ll be hooked, just like me. Share your loaves on social media with #olivemagrecipes.
