In the bowl of a stand mixer fitted with a dough hook, combine the bread flour, water, and sourdough starter. Mix on low speed until a shaggy dough forms.
Cover the bowl with plastic wrap or a damp towel and let rest for 30 minutes to 1 hour.
Add the salt to the dough and mix on low speed for another 2-3 minutes, until it is fully incorporated.
Increase the speed to medium and knead the dough for 5-6 minutes, until it becomes smooth and elastic.
Place the dough in a clean, lightly oiled bowl and cover with a damp towel. Let the dough rise at room temperature for 4-6 hours, until it has doubled in size.
Once the dough has risen, turn it out onto a lightly floured surface. Fold the dough over onto itself a few times to release any air bubbles.
Shape the dough into a round or oblong loaf, depending on your preference. (See the videos and instructions above for shaping tips). Place the shaped dough into a proofing basket, seam side down.
Cover the dough with plastic wrap or a damp towel and place in the fridge overnight. [If you cannot wait to test your delicious bread, simply let it rise again for 1-2 hours, until it has increased in size by about 50%].
Preheat the oven to 450°F (230°C) and place a baking stone or dutch oven inside to preheat as well.
Carefully transfer the dough to the baking stone or dutch oven. Score the top of the dough with a bread lame or sharp knife.
Bake the bread for 45 minutes, or until the crust is a deep golden brown, and the internal temperature of the bread reaches 200°F (93°C). If you are using a dutch oven, remove the cover about half way through the baking time.
Remove the bread from the oven and let it cool on a wire rack before slicing and serving.
