Allow the soup to cool completely before freezing. If you freeze hot soup, the jars may crack or break due to the sudden temperature change.
Mason jars are ideal for freezing soup because they are airtight and can withstand low temperatures. Choose jars with lids that are in good condition and seal tightly.
Leave 1/2 to 1-inch headspace at the top of each jar to allow for expansion during freezing. This will prevent the jars from breaking.
Ladle the cooled soup into the jars, leaving the recommended headspace. Wipe the rims of the jars clean with a damp paper towel to ensure a proper seal.
Gently tap the jars on the counter to release any trapped air bubbles. If necessary, use a chopstick or wooden skewer to poke the bubbles.
Tighten the lids of the jars securely. Make sure the lids are properly sealed to prevent air from entering the jars during freezing.
Place the jars of soup in the freezer and freeze for at least 4-6 hours, or overnight. The soup will keep in the freezer for up to 3 months.
When ready to use, thaw the frozen soup in the refrigerator overnight or at room temperature for several hours. You can also place the frozen jar of soup in a sink filled with cold water to speed up the thawing process.
To save space in the freezer, you can stack the jars of soup on top of each other.
To reheat the thawed soup, you can microwave it in a microwave-safe bowl or saucepan or heat it on the stovetop over medium heat until warmed through.
Before consuming, always check the quality and smell of the soup to ensure it is still safe to eat.
