In a large mixing bowl (a stand mixer is best if you have it) dissolve the yeast and sugar in warm water.
Add the melted butter into the mixture and stir it in.
Add in salt and 2 cups of flour to the yeast mixture. Stir till combined.
Add 1/2 cup of the flour at a time, while stirring slowly, combining thoroughly after each addition. Until you've added 6 cups of flour total.
Add more flour 1 TBS at a time as needed till the dough is pulls away from the sides of the bowl. (Mine needed 6 1/4 cups total)
After the dough pulls from the sides, knead it for 8 minutes.
Grease a bowl with oil.
Roll the dough into a ball and place it into the bowl. Brush top of the dough ball with oil too.
Cover with a towel or greased plastic wrap and set the bowl in a warm place, to let it rise.
Let the dough rise till doubled in size, about 1 hour.
Punch the dough down to remove the air.
Divide the dough into two equal halves.
Roll each loaf into a flat rectangle, about 9inches (as wide as the bread pan) and about 1/2 inch thick.
Rub the tops of each rectangle with melted butter.
