Prepare the Detroit pizza dough the day before and allow to proof overnight, in the Detroit pan, following the steps linked above.
Take the dough out of the fridge 4-6 hours before baking.
Preheat your kitchen oven to 550F.
Place the pan on a pizza steel/stone, or on the bottom of your oven, to par-bake the dough for 5 minutes.
Remove from oven. Carefully top with cheese (pan will be hot). Return to oven and bake for another 6-7 minutes or until cheese is bubbly and the edges look browned.
Remove from oven. Top with two large stripes of Creole sauce, followed by shrimp. Sprinkle on green onion, slice, and serve.
