Most bacon keepers separate solids from grease by using a removable strainer or grate that catches bits while allowing liquid fat to drain into a lower reservoir. Bacon cooking trays often have angled or slanted ridges that channel grease away from the meat into a built-in collection area for easier disposal.

They’re used to collect and strain used bacon grease for storage or disposal, to cook and drain bacon or small meats in microwave/oven trays, to store cooked meat or leftovers in airtight containers, and to organize or transport snacks and charcuterie with divided portable boxes.
