How Many Slices in a Costco Pizza? the Complete Party Planning and Ordering Guide
Transporting 18-inch pizza boxes requires preparation. The wide footprint prevents these flat containers from sitting level in most passenger car footwells. Place boxes flat on a folded blanket in your trunk or across a cleared rear bench seat. Keep the boxes level to prevent liquid cheese and meat oils from sliding toward one side during transit.
Costco crust uses high-gluten flour, making it soft and chewy when hot, but prone to becoming leathery when reheated incorrectly in a standard microwave. Skip the microwave entirely. Instead, use these two reliable reheating techniques:
For a crisp crust with melted toppings, heat a heavy cast-iron skillet over medium heat on your stove. Place the cold slice in the dry skillet for two minutes until the bottom crisps. Add three drops of water to the pan surface away from the crust, cover the skillet with a tight lid, and steam for one minute. The trapped vapor melts the cheese while the pan surface restores bottom crunch.
For large batches, arrange slices on a preheated baking sheet lined with aluminum foil. Bake in an oven set to 375°F (190°C) for 6 to 8 minutes. Avoid using high broil settings, which scorch the cured meats and dry out the cheese before the dense crust warms through.
