In a large bowl, combine flour, yeast, sugar, and salt. Give it a good stir so everything is evenly distributed. Pour in the water and sunflower oil. Stir until the dough starts to come together, it should be a bit sticky.
On a floured surface, knead the dough for about 5–7 minutes until it’s smooth and elastic. Place the dough back in the bowl, cover with a clean towel, and let it rise in a warm spot until your dough doubles.
Knead the dough briefly again, then shape it into a round and place it in a cake pan. Let it rise for another 15–20 minutes.
Brush the top with water and sprinkle with flour. Then, use a sharp knife to make shallow slashes.
Pop it in a preheated oven at 180°C/350°F for 60 minutes. Let the bread cool for a while before slicing.
