Prepare all of the ingredients per the instructions
Place all of the ingredients in the inner liner of the Instant Pot and stir.Note: If you are using frozen broth, you won't be able to stir it, but it will still cook just fine.
Place the inner liner into the Instant Pot base and close and lock the lid, ensuring the Pressure Valve is in the Sealing position
Select the Soup/Broth button and set the cooking time for 15 minutes.
Once cooking time is complete, allow a 10-minute NPR (Natural Pressure Release). That just means letting the Instant Pot sit for 10 minutes before releasing the rest of the pressure - this allows the contents to "settle down" a bit.
After the 10-minute NPR, do a QR (Quick Release) by carefully turing the Pressure Valve from Sealing to Venting.
Once the rest of the pressure has been released, and the Float Valve has droppe, carefully remove the lid and transfer the Inner Liner to a heatproof surface.
Remove the Bay leaf and give the soup a good stir.
Serve immediately or refrigerate or freeze for later use.
