Let the baked beans come to room temperature. If you put hot baked beans straight into the freezer, the container can break because of a dramatic change in temperature.
Fill the container or Mason Jar with baked beans. Important: leave 1-2 inches of room at the top of the container or Mason Jar to let the frozen beans expand.
Sprinkle some salt in with the beans. It’ll stop them from becoming mushy when you defrost them.
If your baked beans have meat (like pork), cover the meat with sauce to stop it from drying out in the freezer.
Close the container, sealing it tightly. For Mason Jars, screw on the lid but leave it loose to tighten later.
Write today’s date on a freezer label and stick it to the container.
Store the container at the back of the freezer. Avoid putting the container in the freezer door, which isn’t as cold as the rest of the freezer.
