In a large bowl, add water, yeast, flour, and salt. Mix with a wooden spoon until a sticky dough forms. Drizzle 2 tablespoons of olive oil over the dough in the bowl. Cover the bowl with a dish towel and let it rise for 2 hours until it has doubled in size.
Once the dough has risen, generously coat an 8x8 baking dish with 2-3 tablespoons of olive oil. Enough oil so the dough won’t stick to the bottom.
Gently transfer the dough from the bowl to the oiled baking dish. Let it sit for 1 hour until it has doubled in size again.
Preheat the oven to 450°F. Drizzle the dough with remaining olive oil. Dimple the dough with your fingers and sprinkle with flaky sea salt.
Bake for 25 minutes until golden brown. Once the bread is out of the oven, add more salt, if desired. Cut, serve and enjoy!
