In a large bowl, dissolve yeast in warm water.

Add the sugar, salt and 3 cups flour.

Beat on medium speed for 3 minutes.

Stir in the rest of the flour.

A soft dough will form.

On a floured counter, knead until smooth about 8-10 mins.

Place in a greased bowl, turning once to grease the top.

Cover and let rise in a warm place until doubled, about 1 hour.

Punch dough down.

Turn onto a floured surface; divide in half.

Shape each half into a loaf.

Place each seam side down on a parchment lined cookie sheet.

Cover and let rise until doubled, about 30 minutes.

Preheat oven to 400°.

With a knife, make four slashes across top of each loaf.

Bake 20-25 minutes or until golden brown.

Let cool on a rack.
