Gastro pans changed the game in commercial kitchens.
Back in 1964 in Switzerland, the Gastronorm system (aka gastro pans) was born.
For the first time, chefs had a universal sizing standard for trays and containers.
Base size: GN 1/1: 530 Ă— 325 mm with halves, thirds, and smaller variations built off it.
Before this, every brand had their own sizes. Nothing fit across ovens, fridges, or hot boxes. Kitchens were clunky, inefficient, and full of wasted space.
The gastro pan changed that forever:
1. Interchangeable – straight from fridge → oven → bain-marie → buffet
2. Efficient – No wasted space, easy portion control
3. Streamlined workflow – less handling, less washing, safer food
4. Global standard – every major equipment manufacturer built around it.
By the 70s and 80s, hotels, caterers, and airlines jumped on board.
Today, you won’t find a serious commercial kitchen without them.
