Remove your sourdough starter from the fridge for at least an hour before starting the bread-making process.
Once the starter is warm, mix it with water and salt in a large mixing bowl. Add the flour and any optional add-ins, like seeds or olives. Mix everything until the dough is well combined.
Cover the bowl with plastic wrap or a large plastic bag and let the dough rise at room temperature for 18-22 hours until it doubles in size. I typically start the bread around 3 p.m. the day before baking and leave it overnight.
Once the dough has risen enough, sprinkle some flour on top of it and your hands. Take a portion of dough from the bottom to stretch and fold it about 5 or 6 times.
Form the dough into a ball, transfer it to a flour-lined bread-proofing basket or parchment-lined bowl that’s about the same size as the Dutch oven you’ll bake it in, and let it rise again for another 2-3 hours.
Preheat the oven to 450°F. While it’s heating, place a Dutch oven inside to warm it up as well.
Transfer the dough to the hot Dutch oven, and score the top with a sharp knife or sourdough bread lame to allow steam to escape. Sprinkle the top with additional flour before placing it in the oven.
Bake the sourdough bread with the lid on for 35 minutes, then remove the lid and bake it for another 15-20 minutes until the top is golden brown. Allow the loaf to cool completely on a wire rack before slicing it. Happy eating!
Notes
Use a scale: Weigh your ingredients, especially the flour and water, rather than measuring by volume to get precise and consistent results every time.Mind the proofing time: Over- or under-proofing can ruin your bread. Rather than strictly adhering to the clock, watch for signs that the dough is ready for baking, like doubling in size and having a slightly domed shape.Be gentle with the dough: Be gentle when you're folding and stretching the dough to preserve its airy structure.Cooling: Allow the bread to cool completely on a wire rack before slicing it. Cutting into bread too early can cause a gummy texture since the bread continues to cook from residual heat.The time it takes for your dough to rise will vary depending on your climate. As a general guideline, it should almost double in size. I will typically start my bread around 3 p.m. the day before baking it, then let it rise overnight.The stretching and folding technique strengthens the dough's structure and distributes the gases and nutrients for the yeast, promoting a more even rise and airy crumb.A second rise helps the dough to achieve its final structure and size. This is also a good time to preheat your oven.Scoring the dough helps it rise uniformly and adds an artisanal, rustic touch.Nutritional information is a rough estimate and should not be taken as health advice.
