Mix Dry Ingredients: In a large bowl, whisk together flour, salt, and yeast.
Add Water: Gradually add warm water (and sugar if using), stirring with a wooden spoon until a shaggy dough forms.
Rest Dough: Cover the bowl with a damp towel and let it rise in a warm place for 1.5–2 hours (until doubled in size).
Preheat Oven: Preheat to 425°F (220°C) and lightly grease a loaf pan.
Shape Dough: Transfer the dough to the pan, smoothing the top with oiled hands.
Bake: Place in the oven and bake for 25–30 minutes until golden brown and hollow when tapped.
Cool: Let it rest in the pan for 5 minutes, then transfer to a wire rack to cool completely.
