In a large bowl, whisk together the bread flour, instant yeast, sugar, and salt.
Pour in the oil and warm water, and stir until all the flour is moistened. The dough will be sticky.
Cover the bowl with plastic wrap or a damp, clean kitchen towel, and set it in a warm area for 2 to 3 hours until the dough doubles in size.
Turn the dough onto a lightly floured surface and gently form it into a round loaf. Place the shaped dough on a piece of parchment paper.
Preheat your oven to 450°F with a Dutch oven inside. Once heated, carefully transfer the dough along with the parchment paper into the Dutch oven. Use a sharp knife or bread lame to score the top of the dough, cover with the lid, and bake for 30 minutes.
Remove the lid and bake for another 10 minutes or until the crust is golden brown and it sounds hollow when you tap the bottom. Remove from the oven and let cool on a wire rack for at least 20 minutes before slicing.
