In a large mixing bowl, combine the all-purpose flour, salt, sugar, and fast-acting yeast. Stir to evenly distribute the ingredients.
Add the warm water to the dry ingredients and mix with a wooden spoon or spatula until a sticky dough forms.
Lightly flour a clean surface and knead the dough for about 5 minutes until it becomes smooth and elastic. If the dough is too sticky, sprinkle a little more flour as needed.
Lightly grease a large bowl with olive oil. Place the dough in the bowl and turn it to coat all sides with oil.
Cover the bowl with a clean kitchen towel or plastic wrap and let the dough rise in a warm place for 30 minutes, or until it has doubled in size.
While the dough is rising, preheat your oven to 450°F (230°C). Place a clean Dutch oven with its lid inside the oven to heat for 30 minutes.
Once the dough has doubled, carefully remove the hot Dutch oven from the oven. Lightly grease the inside with olive oil.
Turn the dough out onto a lightly floured surface and shape it into a round loaf.
Place the dough into the hot Dutch oven. Cover with the lid and bake for 30 minutes.
After 30 minutes, remove the lid and bake for an additional 15 minutes to develop a golden, crispy crust.
Remove the bread from the oven and transfer it to a wire rack. Let it cool for at least 30 minutes before slicing.
