Pour warm water into a large bowl. Stir in white sugar until dissolved, then sprinkle yeast over the surface. Let sit for about 10 minutes, until creamy and frothy.

Mix in salt and vegetable oil using a wooden spoon until well combined.

Gradually add bread flour one cup at a time, mixing until the dough pulls away from the sides.

Transfer the dough onto a floured surface. Knead for 8 to 10 minutes until smooth and elastic.

Place kneaded dough in an oiled bowl, cover with a damp cloth, and let rise in a warm spot until doubled in size, about 1 hour.

Punch down the dough, knead for a couple more minutes, then divide and shape into loaves.

Place the loaves in oiled pans, cover loosely, and let rise for 30 minutes.

Preheat oven to 350°F. Bake the loaves for about 30 minutes until golden brown and sound hollow when tapped.
