Combine yeast, warm water & pressed garlic in a large bowl.
In a separate bowl, mix flour & salt. Stir until combined.
Stir the flour into water mixture one cup at a time & mix until completely incorporated.
Cover dough with greased wax paper (I use the bowl's lid that is not snapped completely tight.) Allow dough to rise for 1 hour.
Lightly oil the bottom of a 10" or 12" cast iron skillet.
Do not punch down the dough but sprinkle flour on top of the dough (it will be sticky). Cover hands with flour & quickly, roughly shape dough into a flattened circle.
Quickly scoop up shaped dough & place into greased skillet, pressing sides to reshape if necessary.
Cover loosely with a greased wax paper, and allow to rise 30 minutes.
Drizzle olive oil on the dough & make a couple of slashes in the top of the dough with a knife. Sprinkle top with coarse salt and minced fresh rosemary.
Bake 35-40 minutes, or until the top is a nice brown color.
Remove from oven and let cool in pan 5 minutes.
Then place bread on a baking rack & cover with clean kitchen towel to allow to cool completely
