Review on 🍪 Chicago Metallic Non-Stick Extra Large Cookie Baking Sheet - 15x21, Metallic Gray: Perfect for Baking Large Cookies! by Michelle Sun

I liked it so much that I bought another one. The pan fits perfectly in my standard oven. Utilizes the maximum possible rack space to efficiently use the space in each rack. I can cook a lot more food with these pans than with the standard pan size. I usually have to wait until each pan is fully cooked before swapping out for the next batch. There aren't many next batches on this pan! This is especially true if you have a lot of baking to do for parties and gatherings. This saves time and energy in the end because you can put more food in the oven at the same time. The size is absolutely perfect. And the pan is very well made. It's a good density for a pan, so it won't warp like some of the thinner pans if your items aren't even or if the temperature changes drastically too much. Excellent metal quality. In addition, the non-stick coating is very durable. It's easy to clean and I've never had a problem with sticky grease or oil sticking to the pan.
