In a small bowl, stir together the lukewarm water, yeast and sugar. Let stand until foamy, 3 to 5 minutes.
Using a standing mixer, mix the flour and salt at low speed. Mix in the yeast mixture and olive oil until a shaggy dough forms. Change to the dough hook attachment and mix at medium speed until smooth, about 6 minutes.
Transfer the dough to a greased, large mixing bowl, turning to coat; cover with plastic wrap and let rise until doubled in size, 45 minutes to 1 hour. Punch down the dough before using. NOTE: For whole wheat dough, use 3/4 cup whole wheat flour and 1 1/2 cups all-purpose flour.
