how to freeze spaghetti Squash

Even though you can freeze raw spaghetti squash, we recommend that you cook it first before freezing it. This will help retain its texture and taste. Cut the squash in half and place it face down on a pan. Bake at 375F for about 30 minutes and then allow it to cool. Fluff it with a fork and place it in a colander for a couple of hours or overnight in the fridge so any excess water drains out. You can then either freeze it as a whole or remove the insides of the squash and place it in a ziplock bag and freezing it for up to 6 months.
