Dennis;
Using a deck oven I always per-bake at 400F, and using an air impingement oven I like to use 375F. I’ve found that it really helps to put on about 1/2 of the normal sauce just before par-baking, then allpy the second half when you dress the par-baked crust to the order. With just sauce on the crust you can store it at room temperature without any problem, or you can refrigerate it. Just make sure you are consistent in using always refrigerated par-bakes or non-refrigerated par-bakes as there will be different baking times for the two. I’ve also found that if I an baking the pizza from a par-baked crust and using a deck oven, I may need to put a screen under the pizza to prevent the bottom from getting too dark during the final baking. By the way, deep-dish pizzas made on a par-baked crust are absolutely great in my opinion, light, tender, and crispy.
