Thirteen Chefs Extra Large 24 x 18 Black Cutting Board - Pro Grade

In this review of the Thirteen Chefs extra large 24 x 18 black cutting board, the bottom line is simple: this is a workhorse for chefs who need a stable, oversized prep surface. Designed for professional kitchens, the board's half-inch HDPE construction gives it real heft and durability, so it resists warping and stays flat under heavy use. If you regularly break down large roasts, whole poultry or big batches of vegetables, the generous surface area and sturdy feel are the single biggest reasons to pick this board over standard home-size options.

Key Features

• Extra large surface: The 24 x 18 in area provides ample space to prep multiple ingredients at once, speeding up mise en place and reducing trips to the counter.
• Commercial-grade HDPE: Made from high density polyethylene, the board is warp resistant and built to last under heavy daily use in a busy kitchen.
• Half-inch thickness: The 1/2 in thickness gives the board weight and stability, helping it resist sliding and stay flat while chopping.
• NSF and dishwasher rated: Rated for commercial dishwashers and stamped for food service use, it fits professional sanitation routines.
• Black color: The dark surface is ideal for cooked meats and hides knife marks and stains, making it well suited to BBQ and steak prep.
• Made by an experienced brand: From a company focused on food service, the board reflects decades of kitchen use and practical design.

Who It's For

This board is best for professional cooks, caterers and home chefs with large kitchens who need a stable, oversized prep area for whole roasts, large cuts and batch cooking. It suits anyone who values a durable, warp-resistant surface that can stand up to daily commercial dishwasher cycles.

Conversely, smaller households and cooks who rely on compact sinks or standard home dishwashers should look elsewhere; the board is heavy at about 7 pounds and may not fit in sinks or smaller dishwashers, and it can be awkward for a single person to clean alone.
