In a large bowl, give the water or honey, sugar, and yeast a stir and let it bloom for 5 minutes.
Add in the AP flour, salt, 1 tablespoon thyme, and oil. Mix the dough together with a large spoon. Avoid over-mixing.
Note: The dough will be sticky. Avoid adding more flour.
Grease a large mixing bowl and gently roll your yeast dough inside. Cover with plastic and let it rise for 1 hour.
Preheat the oven to 400°F.
Grease a cast iron skillet with olive oil. Using a rubber spatula, roll the risen dough into the greased skillet. Sprinkle with flaked salt and 1 tablespoon thyme. Press a thyme sprig on top.
Bake for 20 minutes until the loaf is golden brown. Cooking time will vary depending on how big your skillet is.
