In a mixing bowl, combine the sourdough starter and warm water. Stir until well mixed.
Add the flour and salt to the mixture. Stir until it forms a shaggy dough.
Drizzle in the olive oil and mix until incorporated. The dough will be slightly sticky.
Transfer the dough onto a floured surface. Knead it for about 5 minutes, adding flour as necessary until the dough is smooth and elastic.
Shape the dough into a ball and place it in a lightly oiled bowl. Cover it with plastic wrap and let it rest for 1 hour at room temperature.
Preheat your oven to 475°F (245°C) while the dough is resting.
After resting, punch down the dough and transfer it back to a floured surface. Divide the dough into two equal portions for two pizzas or leave it whole for one large pizza.
Roll out the dough to your desired thickness, using a rolling pin or your hands.
Transfer the dough to a baking sheet or preheated pizza stone.
Top it with your favorite sauce, cheese, and toppings.
Bake in the preheated oven for 12-15 minutes or until the crust is golden brown and the cheese is bubbly.
Remove from the oven, slice, and enjoy!
