In a large bowl, whisk together the flour, yeast, sugar, and salt until well combined.
Add warm water and mix until a sticky dough forms with no dry flour remaining.
Cover with plastic wrap and let rise at room temperature for 2 hours.
After rising, pulling edges toward center to form a loose ball.
Drizzle olive oil over dough, turning to coat all sides.
To shape: With oiled hands, lift dough and fold like a letter - fold top third down, bottom third up, then fold sides under. Form into a loaf shape with seam at bottom.
Place shaped dough seam-side down in buttered or parchment-lined 9x5-inch loaf pan.
Cover and let rise 1 hour until dough reaches top of pan.
Bake at 375°F (190°C) for 45 minutes until golden brown.
Cool in pan 10 minutes, then on wire rack for at least 20 minutes before slicing.
