Vesteel 12.5 inch Baking Pan with Rack Set (2 Pans & 2 Racks), Stainless Steel Quarter Size Toaster Oven Tray with Cooling Rack, Heavy Gauge & Dishwasher Safe

I recently wrote a review on the Vesteel 12.5 in. air fryer pan and basket and have some additional comments on Vesteel air fryer sheet pans in general. Use parchment paper instead of aluminum foil, don't double up on sheet pans, (i.e., using ovens original pan plus putting the Vesteel pan on top of it), just put the pan on the ovens wire rack. Most important is the temperature. For the 12.5 pan 400 deg. works best, 425 is fine, but it warps at 450. Most every thing I do is at 400 or below. The 10 in. pan seams to be able to handle up to 450 with no warping. Once I learned the pans and how to use them, love 'um. Vesteel products that I've seen and used look good, work well and are a very good value.
