In a large mixing bowl, dissolve the sugar in warm water and sprinkle the active dry yeast on top. Let it sit for about 5-10 minutes until foamy.
Add the flour, salt, and olive oil to the yeast mixture. Stir with a wooden spoon or spatula until a dough forms.
Turn the dough onto a floured surface and knead for about 5 minutes until smooth and elastic. If the dough is too sticky, add a bit more flour.
Grease the baking sheet with olive oil or line it with parchment paper. Press the dough into the sheet pan, stretching it to fit.
Preheat the oven to 450°F (232°C).
Spread the pizza sauce evenly over the dough, leaving about half an inch around the edges.
Sprinkle shredded mozzarella cheese over the sauce, then add your choice of assorted toppings.
Bake in the preheated oven for about 15-20 minutes or until the cheese is bubbly and the crust is golden brown.
Remove the sheet pan pizza from the oven and let it cool for a few minutes. Garnish with fresh basil leaves if desired.
Slice into squares and serve hot.
