In a large mixing bowl, mix warm water, sugar, and yeast. Let sit for 10–15 minutes until frothy.

Add salt and oil to the mixture, then gradually mix in the flour one cup at a time until a dough forms.

Knead the dough on a floured surface for 8–10 minutes until smooth and elastic.

Place dough in a greased bowl, cover with a cloth, and let rise in a warm place for 1–2 hours or until doubled in size.

Punch down the dough, divide it into two loaves, and place in greased loaf pans.

Cover and let rise again for 30–45 minutes until dough reaches the top of the pans.

Bake at 350°F (175°C) for 30–35 minutes until golden brown and sounds hollow when tapped.

Remove from pans and cool on a wire rack before slicing and serving.
