Creating a Sicilian square pizza is straightforward and enjoyable. Follow these steps to make your own delicious pizza:

1. Activate the Yeast: In a small bowl, combine warm water, sugar, and yeast. Let it sit for about 5-10 minutes until foamy.
2. Mix Dry Ingredients: In a large mixing bowl, whisk together the flour and salt until well combined.
3. Combine Mixtures: Pour the yeast mixture and olive oil into the flour. Mix until a dough forms.
4. Knead the Dough: Turn the dough onto a floured surface and knead for about 8-10 minutes until smooth and elastic.
5. First Rise: Place the dough in a greased bowl, cover with a damp cloth, and let it rise in a warm place for 1 hour or until doubled in size.
6. Prepare the Baking Pan: Grease a 9×13-inch baking pan with olive oil.
7. Shape the Dough: Once risen, punch down the dough and transfer it to the prepared pan. Stretch it to fit the corners and edges of the pan.
8. Second Rise: Cover the dough again and let it rise for an additional 30 minutes.
9. Preheat Oven: Meanwhile, preheat your oven to 475°F (245°C).
10. Add Sauce and Cheese: After the second rise, spread the marinara sauce evenly over the dough. Sprinkle mozzarella cheese and then add your desired toppings.
11. Sprinkle Parmesan: Finish by sprinkling grated Parmesan cheese over the top.
12. Bake the Pizza: Place the pan in the preheated oven and bake for 25-30 minutes or until the crust is golden brown and the cheese is bubbly.
13. Cool: Once baked, remove the pizza from the oven and let it cool in the pan for about 5-10 minutes.
14. Slice and Serve: Cut the pizza into squares and garnish with fresh basil leaves before serving.
