A watermelon is a large fruit and it can be difficult to eat the entire thing before it goes bad. If you want to preserve leftover melon, can you freeze it?

Can You Freeze Watermelon?

Yes, watermelon can be frozen, but it will be mushy when thawed. Enjoy whole chunks of watermelon while it's fresh because it will not be the same after freezing.

Frozen watermelon is not useless by any means. It is perfect for drinks like smoothies and margaritas and can be a taste of summer to enjoy in the coldest months of the year.

Watermelon also makes a delicious sorbet or granita.

How to Freeze Watermelon

Frozen watermelon will be good for 8-12 months, which is perfect because it will be watermelon season by the time you run out!

Preparing watermelon for the freezer is very easy and should take less than 10 minutes. This flash freezing method creates individually frozen chunks of fruit that are easy to store and use as needed. When you are ready for a smoothie, just pull out 4 or 5 pieces and close the container back up.

  1. Chop the melon into small cubes or balls.
  2. Remove all of the seeds.
  3. Spread the pieces out on a baking sheet so they do not touch each other.
  4. Put the tray in the freezer and flash freeze for a few hours or until firm.
  5. Transfer to a freezer-safe container or storage bag and store in the freezer.

Why flash freeze watermelon? If you simply place fresh watermelon chunks in a container, they will freeze together and you will need to chisel them apart.

It can be a mess, so a little extra effort in the beginning is worth it.

Sweet and Juice Packed Watermelon

As an alternative to flash frozen cubes, you can pack your watermelon with sweetener or juice and freeze the entire container. 

Granulated sugar and simple syrup can both be used to sweeten your watermelon.

This is a nice option if you intend to use the fruit for desserts or need drinks for a party after watermelon season is over.

  1. Cut watermelon into chunks and remove all of the seeds.
  2. Place in a freezer-safe container, leaving about 1/2 inch of room at the top (watermelon expands as it freezes).
  3. Cover the watermelon with sugar or simple syrup.
    • For sugar, use about 1/2 cup granulated sugar for every pound of watermelon. Mix well so all of the pieces are covered with sugar.
    • For simple syrup, add enough syrup to cover the watermelon completely. 
  4. Seal the container and store in the freezer until needed.

Pineapple, orange and other fruit juices can also be used to add extra flavor. This is a fun option for blended drinks.
