Can You Freeze Watermelon?

Sweet, plump, and juicy, nothing celebrates summer quite like watermelon. However, once these large pink melons are sliced, they spoil fairly quickly, even when kept in the refrigerator.

As its name suggests, watermelon consists of a high water content. Despite this, it can be frozen to extend its shelf life well into the winter months.

This allows you to get a taste of summer all year long and avoid wasting leftovers when the melon is just too big to consume before it starts spoiling.

In this watermelon freezing guide, you will learn how to preserve the melon in the freezer long-term and discover delicious ways to use it after thawing.

Types of Watermelon

Watermelon has a thick rind and juicy crisp center. They range from 20 cm (8 in) to over 60 cm (24 in) in diameter. The outer skin is usually mottled dark green with a white inner rind. The fruit flesh is commonly pink or red with pips, however, seedless watermelons are also available.

Watermelon is eaten plain sliced, in a fruit salad, as part of a fruit platter, candied, pickled, or preserved in sugar syrup as an addition to cheese platters, crackers, or bread. Watermelon is also popular in smoothies, juices, and cocktails.

Can Watermelon Be Frozen?

So, can I freeze watermelon?

Yes, watermelon can be frozen to extend its shelf life. Due to its high water composition, the melon pretty much turns into solid ice blocks on freezing and will lose some of its firm, plump texture once thawed.

Although this means watermelon won’t be quite the same after it has been frozen, there are many different and delicious ways to enjoy the pink melon after it has been stored in the freezer.

There are various methods to freeze watermelon depending on how you plan to use it later. Follow the below instructions carefully to ensure the watermelon stays well-preserved and does not develop freezer burn.

How To Freeze Watermelon

Watermelon should always be frozen freshly cut. If you are freezing leftover watermelon that has already been sliced and refrigerated for a day, make sure it is still firm and slightly crisp. 

Remove any soggy, sour, or soft parts as these will not freeze well and are prone to breeding harmful bacteria.

Step 1: Wash

Give uncut watermelon a good wash before handling.

Step 2: Peel and Cut

Cut the watermelon into quarters and slice the melon flesh away from the rind. Remove the hard, black pips from the melon and cut it into cubes or slices. Alternatively, cut the watermelon in half and use a melon-baller to scoop out watermelon rounds, discarding the seeds.

Step 3: Prepare and Pack

Option 1: Flash Freeze

Once you have cut cubes, slices, or formed watermelon balls, spread them out in a single layer on a parchment-lined baking tray.

Optionally, you can toss the watermelon pieces in granulated sugar before placing it on the tray to assist in the preservation of the color and sweetness.

Place the baking tray in the freezer until the pieces are frozen. Remove the frozen watermelon from the tray, pack the pieces into resealable freezer bags, and press out any air before sealing tightly.

Option 2: Sugar Syrup

Another way to preserve the watermelon flavor and texture is by submerging the fruit in a simple syrup. The result after thawing will be somewhat similar to canned fruit.

To make a light sugar syrup, combine 9 cups of water with 2 ¼ cups of granulated sugar (1200ml water and 425g sugar). Heat them together in a saucepan. Bring the mixture to the boil and stir until the sugar has completely dissolved. Once dissolved, the mixture will be clear or slightly white. Remove it from the heat and let it cool.  

Portion the watermelon into airtight freezer-friendly containers or zip lock freezer bags. Pour the cooled syrup over the watermelon pieces until just covered.

If using a container, place a piece of parchment paper against the surface of the fruit to keep it submerged and protected from air before closing. If using a zip lock bag, press out any air before sealing the bag.

Option 3: Puree

Freezing pureed watermelon is perfect for use in smoothies.

Place the cut watermelon in a blender and blitz until smooth. Pour the puree into an ice cube tray and place it in the freezer. Once frozen, remove the watermelon cubes from the tray and place them into a freezer bag, removing the air from the bag before sealing.

If preferred, you can also freeze the puree in larger portions instead of in ice cubes. Pour the puree into a ziplock freezer bag. Make sure to press out the air from the top of the bag before sealing to prevent freezer burn.

Step 4: Label and Freeze

Regardless of the method, label the container or freezer bag with the date before placing it in the freezer. This way, you can keep track of how long the watermelon has been stored.

How To Thaw Frozen Watermelon

Watermelon is best used only slightly thawed to maintain a firm, chilled texture. When using watermelon in a smoothie, cocktails, to make sorbet, or in drinks, always use it from frozen. 

If you do want to thaw watermelon that has been preserved in a sugar syrup, place the container or freezer bag on a plate in the refrigerator to thaw overnight. Stir the mixture occasionally.



Although high in water content, watermelon can be frozen to preserve its color and sweet fruity flavor. Preserving watermelon in a sugar syrup or coating it with granular sugar when freezing will enhance its preservation.

It is also vital to protect the fruit from contact with air when freezing, keeping it well sealed.

Whizz pureed watermelon ice cubes with other ingredients to make a refreshing smoothie or cocktail. Frozen watermelon is a sweet taste sensation as a melon sorbet or even as a fruity pink popsicle. Freeze leftover watermelon and enjoy summer sweetness all year long.
