In a large mixing bowl, combine warm water, sugar, and yeast. Let sit for 5 minutes until frothy.
Stir in olive oil, salt, and 2 1/2 cups of flour. Mix until a shaggy dough forms.
Turn out onto a floured surface and knead for about 5 minutes, adding more flour if needed, until smooth and elastic.
Place the dough in a lightly oiled bowl, cover with a clean towel, and let rise in a warm spot for 30 minutes.
Punch down the dough and roll it out to fit your pizza pan or baking sheet.
Top with your favorite sauce and toppings, then bake in a preheated oven at 475°F for 12-15 minutes or until crust is golden and toppings are cooked.
