There are certain differences in the baking process between different brands of pizza, and these differences must be noted for the best taste and an evenly cooked pizza. You'll also want to keep careful watch on a baking timer or clock to make sure you don't burn your Jack's pizza pie.
Take your Jack's pizza out of the freezer. Remove the plastic wrap and cardboard.
Preheat the oven to 450 degrees. Place the frozen pizza on your oven's center rack and close the oven door.
Cook the pizza for 15-18 minutes. You may use a kitchen timer to remind you when the time is up. Check the pizza at 15 minutes to see if the cheese in the middle of the pie is melted. If it's not, let it cook another three minutes or so until the cheese on top is melted and golden brown.
