Prepare the Dough:

In a large mixing bowl, combine warm water, sugar, and yeast. Let sit for 5-10 minutes until the yeast becomes foamy.

Add salt and melted butter, then gradually stir in 5 cups of flour. Mix until the dough comes together.

Transfer the dough to a floured surface and knead for 8-10 minutes, adding additional flour as needed, until the dough is smooth and elastic.

First Rise:

Place the dough in a greased bowl, cover with a damp cloth, and let rise in a warm place for 1-1.5 hours or until doubled in size.

Shape the Loaves:

Punch down the dough and divide it into two equal portions. Shape each into a loaf and place into greased 9×5-inch loaf pans.

Second Rise:

Cover and let rise for another 30-45 minutes until the loaves double in size.

Bake the Bread:

Preheat oven to 375°F (190°C).

Bake for 25-30 minutes until golden brown and the loaves sound hollow when tapped.

Cool and Serve:

Brush the tops with melted butter, if desired, and let cool in the pans for 10 minutes. Transfer to a wire rack to cool completely before slicing.
