Sourdough Basics
This bread machine recipe makes sourdough baking super simple! The key is having an active, bubbly sourdough starter.
Your starter should be fed and at its peak when you add it to the machine. The dough comes in two options – choose the 65% hydration for a firmer, more traditional loaf, or try the 75% hydration for a lighter, airier texture. Both make wonderful bread!
Storage Tips
Your fresh sourdough will stay tasty for 4-5 days when stored properly. Let it cool completely, then keep it in a paper bag or bread box at room temperature.
Don’t store it in the fridge, as this makes it go stale faster. If you want to keep it longer, slice the whole loaf once it’s cool and pop it in the freezer – it’ll stay fresh for up to 3 months! Just toast slices straight from frozen whenever you want them.
Serving Ideas
This sourdough makes amazing sandwiches! The mild tang works beautifully with both savory and sweet toppings.
Try it fresh with good butter and honey for breakfast, or make grilled cheese for lunch – the crispy crust is perfect for it.
For dinner, serve thick slices alongside soup or stew to soak up all the yummy flavors. Day-old bread? Toast it and top with mashed avocado and a sprinkle of sea salt!
Helpful Tips
Your bread machine does most of the work, but here are some friendly pointers: Check your dough during the first few minutes of kneading – if it looks too dry, add water a tablespoon at a time.
If it’s too sticky, sprinkle in a bit more flour. The dough should form a soft ball that cleans the sides of the pan. New to sourdough? Start with the 65% hydration recipe – it’s easier to handle and still makes wonderful bread!
