I like to freeze chili in individual serving size portions. Having individual portions makes it super easy for anyone in the family to take one out of the freezer and reheat it. These are the containers I use. My second favorite way to freeze chili is to fill a large freezer bag about halfway full. Seal and lie flat. PRO-TIP: Seal the zip top closer 80 percent closed. The press the air out of the freezer bag before you lie it flat.  This method is an excellent space-saving method if you have a drawer in your freezer.
