Best of all, sterilizing jars in an Instant Pot is extremely easy and quick.
What about metal lids?
Yes, you can sterilize metal lids in an Instant Pot. Make sure you unscrew them from the jars and place them separately on the rack inside the Instant Pot. if they are sealed on the jars when sterilizing, the pressure may cause the glass jars to explode inside the appliance.
If you have a Kilner jar with rubber rings in the lid, remove these and sterilize them in boiling water for 3 minutes.

- Thoroughly wash your empty glass jars with soap and hot water. Rinse them properly, making sure to remove all soapy suds. Remove rubber rings – these can be sterilized in boiling water for 3 minutes.
- Fill your instant pot with water. The amount of water depends on the size of your Instant Pot. As a guide, use the following: 250ml (1 cup) for a 3-quart Instant Pot, 500ml (2 cups) for a 6-quart Instant Pot, 750ml (3 cups) for an 8-quart Instant Pot, and 1 liter (4 cups) for a 10-quart Instant Pot.
- Insert a steam rack or basket to prevent the jars from touching the base of the Instant Pot. This could either crack the jar or cause the Instant Pot to malfunction.
- Place your jars upside down in the instant pot. You can also sterilize metal lids, but don’t place them on the jars when you sterilize them. Leave them loose inside your Instant Pot.
- Close the lid of the instant pot, making sure it is properly sealed.
- Modern Instant Pots have a sterilize function, but you can still use older models. Select either ‘sterilize’ (modern Instant Pots), or ‘steam’ or ‘pressure cook’ (older Instant Pots) and set time for 15 minutes.
- When the sterilization process is complete, release the pressure valve on your instant pot. Allow the instant pot to cool down for about 5 minutes and then remove the jars and lids using a jar lifter or tongs.
- Fill the jars with your preserve immediately, while they are still warm.
