In the bowl of a stand mixer, add yeast, water, salt, and 4 cups of flour. Knead on a slow speed until the flour has started to combine. Increase speed to medium and gradually add in the remaining flour until dough pulls away from the sides of the bowl.
Transfer to a lightly greased mixing bowl, cover with plastic wrap, and let rise until double in size, about 30-45 minutes.
Divide dough in half. Roll each half into a rectangle. Roll up tightly from the long end. Place onto a lightly greased baking sheet or into a french bread pan. Cover with a kitchen towel and let rise for 30 minutes.
Preheat oven to 375 degrees. Use a sharp knife to cut diagonal slashes on the top of each bread loaf. Brush loaves with egg wash.
Bake in preheated oven for 25-30 minutes, or until golden brown. Remove from oven and brush with the melted butter. Enjoy!
