  7. When time is up, release pressure using the quick release method. Consult the manual for more information on how to do this.  After the pressure has been released and the float valve has dropped, remove the lid carefully as steam will come out. Remove the squash form the Instant Pot using tongs. Use a fork to fluff out the noodles and remove them from the squash shell.

  8. Squash may be served immediately, or refrigerated in an airtight container to use later. If using later, reheat briefly to avoid overcooking.
