In a small bowl, mix together the warm water, yeast, and sugar. Let sit for 5 minutes; it will begin to foam.
Meanwhile, combine bread flour, sea salt, and onion powder in a large bowl. Set aside.
Once the yeast has set (proofed), pour it into the dry ingredients, along with 3 Tablespoons olive oil. Mix until combined and knead together for 3-5 minutes until tacky, but not sticky. Form into a ball. Coat a bowl with a thin layer of olive oil, and place dough in a bowl (you can turn it in the bowl to coat with olive oil). Cover bowl and let sit in a warm area for 1 hour.
The dough will have doubled in size when done; punch the dough and knead for 5 minutes. Begin to roll out dough from the inside out. If it is springing back, the dough needs a few more minutes of rest time. Roll into the desired shape, creating the crust you desire as well.
Bake as your recipe calls for, OR: using a fork, poke holes across the inside of the crust. Bake at 475°F for 5-7 minutes, add toppings, and then continue to bake until cheese is melted and crust is golden brown, usually an additional 10-12 minutes.
Notes
I use sea salt because I like the texture; if you're using table salt or finely ground sea salt, only use 1/2 teaspoon.
