  • Pot
  • Baking sheet
  • Slotted spoon or fine mesh strainer


  • Zucchini or summer squash


  • Fill a large pot with water and bring to a boil. Rinse your freshly picked squash well, and slice or dice with a sharp knife.
  • Place cut squash into the boiling water for 1-2 minutes to kill enzymes and to discontinue oxidation.
  • Transfer squash into a bowl full of ice water for 2-3 minutes to stop the cooking process.
  • Take the squash out with a slotted spoon making sure to shake off the extra water.
  • Spread squash on a cookie sheet trying not to overlap the pieces, freeze completely (about 2 hours).
  • Place frozen squash into freezer bags for storage, removing any access air, and place back into freezer. Keep up to 12 months in the freezer.


You can do this with however much or little squash you have. You may even have to do it in smaller batches if you don't have a lot of freezer space.
