Take the dough out of the fridge 30 minutes ahead. Preheat the oven to 425°F with a rack in the lowest position.
Coat a rimmed half sheet pan with the olive oil. Press and stretch the dough toward the edges and corners. If it springs back, let it rest for 5–10 minutes and stretch again.
Spread the sauce evenly over the dough, leaving a small border.
Top with the mozzarella and your toppings, then sprinkle with the Italian seasoning.
Bake for 18–22 minutes, until the crust is golden brown on the bottom and the cheese is bubbly.
Cool for 5 minutes, then cut into squares.
