In a large non-metallic bowl, mix flour, salt, yeast, and water. Stir well to form a sticky dough. Use your hands or a dough whisk to combine until all flour is incorporated.

Cover with plastic wrap and let it rest at room temperature for 8 hours or overnight until bubbly and risen.

Peel, core, and dice 2 to 3 apples to total about 2.5 cups. Mix with granulated sugar and cinnamon until apples are coated.

Fold the apple mixture into the dough, kneading gently to combine.

Transfer the dough to a lightly greased 5-quart Dutch oven. Cover and let it rise for 2 hours until puffy.

Preheat oven with Dutch oven inside to 425°F. Once hot, carefully place the dough inside and bake covered for 40 minutes.

Remove lid and bake for an additional 10-15 minutes until the top is deep golden brown.

While bread bakes, melt butter in a small saucepan. Stir in brown sugar, maple syrup, and cinnamon until blended. Pour warm over slices before serving.
