01 - In a large bowl, dissolve sugar in warm water. Sprinkle yeast over the water and let stand for 5–10 minutes until frothy.
02 - Add oil and salt to the yeast mixture, stirring until combined.
03 - Gradually add 5 cups of flour, mixing until a soft dough forms. If needed, add additional flour ¼ cup at a time until the dough pulls away from the sides of the bowl.
04 - Turn dough out onto a lightly floured surface and knead for 6–8 minutes until smooth and elastic.
05 - Place dough in a greased bowl, cover with a towel, and let rise in a warm place for 1 hour or until doubled in size.
06 - Punch down dough and divide in half. Shape each half into a loaf and place in greased 9x5-inch loaf pans.
07 - Cover and let rise again for 30–40 minutes or until the dough rises about 1 inch above the rim of the pans.
08 - Preheat oven to 350°F.
09 - Bake for 30–35 minutes until golden brown and loaves sound hollow when tapped.
10 - Remove from pans and cool on a wire rack before slicing.
