Why We Love This Recipe For Watermelon Sorbet

Watermelon is the quintessential summer ingredient and I try to enjoy it as much as I can while it’s fresh! My family often enjoys it in a simple Melon Mint Salad, and my new obsession are these Watermelon Gin Fizz Cocktails!

I love this watermelon sorbet recipe because it’s a refreshing sweet treat after spending the day out in the sun, but the reasons to adore this sorbet don’t stop there…

  • It tastes like real watermelon with no additional flavors. It’s not sickly sweet, the flavor that hits your tongue is pure watermelon!
  • No ice cream maker is required! I love when a recipe is simple and doesn’t call for more complicated equipment than necessary.
  • Watermelon is very healthy! It is rich in Vitamin C, and it is also high in lycopene which is important for heart health. Lycopene also may help protect the skin from UV damage, and as someone who spends a lot of time outside – I’m into that! 
  • It’s just sweet enough to be satisfying, but not overwhelming. Too many homemade sorbet recipes are high in added sugar or taste like they have zero sugar. We found that ¼ cup of added sugar is perfect and only contributes 6 grams of added sugars per serving. The total calories of each generous cup serving is still under 80 calories! 
  • This sorbet also doubles as an ingredient for other recipes! Put it in soda water or prosecco and you’ll instantly take your beverage game to the next level.

Key Ingredients for this Recipe

seedless watermelon, lemon, water, and sugar for a watermelon sorbet

Watermelon

You can tell a watermelon is ripe and ready for use when you knock on it and hear a hollow sound. If it’s more high-pitched it’s not ready. Be sure to get a seedless watermelon, and cut it into ¾-inch cubes before freezing. This will come to about 6 cups.

Sugar, Water, and Lemon

These three simple ingredients combined over high heat will make your simple syrup. Using simple syrup instead of just sugar will disperse the sweetness more evenly throughout your sorbet. After the sugar has completely dissolved into the water you’ll add a little bit of lemon juice to balance the syrup.

How To Make No-Churn Watermelon Sorbet

freeze cubes of watermelon and make a simple syrup on the stovetop

Step 1: Freeze Watermelon

Line a baking sheet with parchment and spread watermelon chunks on it to freeze for at least 4 hours, or overnight.

Step 2: Make Simple Syrup

Combine sugar and water in a small saucepan over high heat. Cook the mixture, stirring until the sugar is dissolved. Then stir in the lemon.

Step 3: Combine Watermelon and Syrup

Transfer half of the frozen watermelon to the food processor fitted with the steel blade attachment. Drizzle half of the hot simple syrup and puree. Scrape down the sides as necessary to achieve smooth results.

This will take several minutes of pureeing and stirring. If the mixture is too icy and won’t puree, drizzle on two tablespoons of water to get it going. Transfer the sorbet to a loaf pan or an air-tight container and set it in the freezer. Repeat with the remaining frozen watermelon and hot syrup.

Step 4: Enjoy!

Serve your sorbet immediately, or pop it in the freezer for up to 2 weeks. Enjoy your refreshing summer treat!

FAQ and Expert Tips

Is watermelon sorbet healthy?

Watermelon sorbet is a delicious low-calorie sweet treat packed with nutrients. Watermelon is ripe with health benefits, including loads of Vitamin C and lycopene which supports heart and skin health. There’s a small amount of added sugar in this recipe, but you can always omit it and make a watermelon nice cream to cut down on sugar.

Can you freeze watermelon?

Yes! Especially if you have too much on hand and it is over-ripe. Note that the texture is mushy once you thaw it so it is better to enjoy it frozen. Besides making this no-churn sorbet with it you can add it to drinks, sangria, or smoothies.

Can you make this in a high-speed blender?

It doesn’t work very well because it is too hard to stir. You could try but it would be more labor-intensive and probably wouldn’t come out as smooth.

How long does watermelon last?

Cut watermelon can last between 3 to 5 days in the refrigerator. For this sorbet recipe, I recommend serving it immediately or freezing it for up to 2 weeks.

What can I do with too much watermelon?

Chop it up and freeze it in chunks or puree it and freeze it in 1 cup containers. You can use the frozen puree to make cocktails (hello prosecco!), add it to smoothies, or simply enjoy it over ice with a squeeze of lime.

What makes a sorbet a sorbet?

Usually, it’s a combination of fruit and simple syrup. Sorbets are traditionally dairy-free, and fat-free as well!

Variations to Try

  • You can flavor your simple syrup with basil or mint! Let it steep for 1 hour and then strain it, but be sure to briefly reheat the simple syrup before adding it to the frozen watermelon. 
  • Us our ginger simple syrup to give it a little spice.
  • Add a splash of heavy cream as you’re mixing to make your sorbet creamier. 
  • You can use an unrefined sweetener such as honey. Melt it into the water as you would for sugar so that it blends evenly.
  • Scoop the sorbet into champagne flutes or coups and top it with prosecco for a special brunch treat! 
  • Make this recipe without added sugar like a watermelon nice cream recipe, and just use water to get the mixture moving with the food processor. An alternative is using your favorite non-nutritive sweetener instead of sugar.
