In a large mixing bowl, add the bread flour, instant yeast, salt, sourdough discard, and bone broth.
Using your hands, mix the ingredients together until it forms a shaggy dough.
Cover with plastic wrap and let it rise in a warm place for 2 to 3 hours or until doubled in size and airy.
Transfer to a lightly floured surface and shape the dough into a round oval if you are using a bread oval, like I am. If you are baking in a Dutch oven, you can just shape it into a ball.
Place on a piece of parchment paper and transfer to your Dutch oven. Make a slit in the top of the dough, I just like to do an “S” shape.
Bake at 450°F for 30 minutes, covered with a lid. Then uncover it and return to the oven and bake again for another 15 minutes or until golden brown.
Let the bread cool completely before slicing, at least 2 hours.
Store in an airtight container for up to 3 days. Or it will last in the fridge for up to 1 week. You can also freeze this in a freezer safe container too for up to 3 months.
