Add warm water, sugar and yeast to a large bowl and stir to combine.

Mix in vegetable oil and add 4 cups of flour with kosher salt. Mix until dough comes together. Add more flour 1/2 cup at a time until a dough ball forms and pulls away from the sides of the bowl. 

Pour onto a floured surface and knead for 3- 5 minutes, adding more flour as needed. Dough will be soft but not sticky.

Grease a bowl and place dough in bowl, turning to coat both sides. Cover with plastic wrap and set aside in a draft free place to rise for one hour or until doubled in size. 

Punch dough down and divide in half. 

Grease 2 loaf pans.

Form dough into loaf shapes and place in pans. Cover with a tea towel and allow to rise 30 minutes or until dough has risen just above the top of the pan.

Preheat oven to 350°. 

Bake for 35- 40 minutes until internal temperature of dough reaches 190° with a digital thermometer. 

Remove from oven and cool in pans for 5 minutes. Remove to a wire rack to cool completely. 

Slice and serve while warm or at room temperature.
