Large Cookie Sheet

360 Cookware Large Cookie Sheet
16.53" x 12.49" Inside Cooking Surface | 5-Ply T-304 Surgical Grade Stainless Steel

The cookie sheet that finally bakes the corners the same as the center.

Every baker who has pulled a sheet of cookies from the oven knows the problem: the ones in the middle are perfect, the ones in the corners are overdone, and the batch that was supposed to be consistent required rotation and vigilance to approximate even results. The problem is not the recipe or the oven — it is the pan. Thin, dark, single-layer cookie sheets absorb and distribute heat unevenly, which shows up most dramatically at the edges and corners where heat concentrates while the center lags behind. The 360 Large Cookie Sheet solves this at the construction level, so the baker doesn't have to solve it at the technique level.

The 5-ply cladded .07 gauge T-304 surgical grade stainless steel construction distributes heat evenly across the full 16.53"x12.49" cooking surface — corner to corner, edge to edge, consistently through the entire bake. The cookie in the corner bakes at the same rate as the cookie in the center. The appetizer at the edge browns the same as the one in the middle. Even heat is not a feature of this pan — it is the construction, built in rather than compensated for, present on the first use and the five hundredth.

At 17.5"x14.22" rim-to-rim, the generous dimensions accommodate the baking that most standard sheets make into a multi-batch project — classroom cookies, holiday exchanges, party appetizers, the cooking that benefits most from having enough room to do it properly. No synthetic coatings, no replacement cycle, oven safe to 500°, and handcrafted in the U.S.A. to the full 360 bakeware standard.

Why we love it:

• Every cookie, every appetizer, every item on the sheet bakes at the same rate regardless of position — no rotation required, no vigilance needed

• Works beyond baking — sheet-pan roasting, appetizers, flatbreads, and any preparation that benefits from a wide, evenly heated surface
• Handcrafted in the U.S.A. — built to the full 360 bakeware standard, indefinitely
• The pan that makes large-batch baking feel less like a production and more like the point

Native Manor Note: The cookie sheet is the piece of bakeware most people buy without thinking and replace most often — thin, dark, warped after a season of use, with a coating that scratched away before it was ever really trusted. The 360 Large Cookie Sheet is built from the premise that a cookie sheet should last indefinitely and bake evenly without asking the baker to compensate for its limitations. Five-ply surgical grade stainless construction delivers even heat corner to corner, every batch, without rotation and without degradation. For anyone who has ever pulled a sheet of cookies from the oven and found the edges done before the center, this is the pan that ends that particular frustration permanently.
