In a large bowl, dissolve the sugar in warm water, then stir in yeast. Let it sit for about 10 minutes until it’s foamy.
Mix in the salt and flour, one cup at a time. Stir until the dough just comes together.
Turn the dough onto a floured surface and knead for 6–8 minutes until smooth and elastic. (Or until your arms ask for mercy.)
Place the dough in a greased bowl, cover it with a damp towel, and let it rise in a warm spot for about 1 to 1.5 hours, until doubled in size.
Punch down the dough (gently—you’re not mad at it), divide it in half, and shape each piece into a loaf. Place on a lightly greased baking sheet or into loaf pans.
Cover and let rise again for 30–40 minutes.
Preheat your oven to 425°F (220°C). If you want a crispier crust, place a pan of hot water on the bottom rack while it preheats.
Bake for 25–30 minutes, or until the crust is golden and the bread sounds hollow when tapped on the bottom.
Optional: Brush the tops with a little olive oil while still warm for extra sheen and a touch of flavor.
