Ingredients Notes

This recipe is proof that you don’t need a long ingredient list to make something amazing. Just two simple items come together to create a creamy, fruity dessert you’ll want to keep stocked in your freezer.

Watermelon is the star here, and the riper, the better. Choose a melon that's sweet, deep red, and seedless if possible. If it has seeds, no worries—just remove them during chopping. Once cubed, you’ll freeze the watermelon to give the gelato its texture.

Sweetened condensed milk brings the creaminess. Its thick, syrupy consistency blends beautifully with the icy watermelon chunks to create that signature gelato texture. It also provides all the sweetness you need, no extra sugar required.

The ratio matters here: roughly 4 cups of frozen watermelon cubes to ½ cup of sweetened condensed milk gives the perfect balance of fruity brightness and creamy richness. Too much milk and it becomes soupy; too little and it might be icy.

No fancy gadgets are necessary—just a high-powered blender or food processor to get things smooth. You’ll also need a loaf pan or airtight container for freezing and serving.

How To Make This 2-Ingredient Watermelon Gelato

Making this gelato is as easy as it gets. Just a few simple steps and a bit of chill time stand between you and the ultimate summer dessert.

Start by cutting your watermelon into small cubes, removing any seeds as you go. Line the cubes on a baking sheet in a single layer and freeze until solid—about 4 to 6 hours or overnight. Freezing them separately prevents clumping, which helps your blender handle them more easily later.

Once your watermelon is frozen, add the cubes to a blender or food processor. Pour in the sweetened condensed milk, and blend until the mixture is completely smooth. You might need to stop and scrape down the sides a few times, and if your machine struggles, add a tiny splash more milk to get things moving.

Taste and adjust if necessary. If your watermelon wasn't super sweet, you can add a bit more condensed milk, but keep in mind the flavor intensifies after freezing.

Transfer the blended mixture into a loaf pan or freezer-safe container. Smooth the top with a spatula and cover tightly with plastic wrap or a lid.

Freeze for about 2-3 hours until scoopable. For firmer gelato, let it chill longer. If it becomes too hard, just let it sit at room temperature for 10 minutes before scooping.

From start to finish (minus freezing time), this whole process takes less than 10 minutes of hands-on work. It’s quick, easy, and perfect for making ahead.

Storage Options

Store your watermelon gelato in an airtight container in the freezer. A standard loaf pan covered tightly with plastic wrap works well, or you can use a reusable silicone container with a lid.

For best texture and flavor, enjoy within 7 days. After that, it may start to crystallize or lose its smoothness, though it will still be edible.

To serve, remove from the freezer and let it sit on the counter for 5-10 minutes to soften slightly. This makes scooping easier and enhances the creamy texture.

Avoid repeated thawing and refreezing, as it can create ice crystals and change the consistency. For individual servings, consider portioning into small containers right after blending.

Variations and Substitutions

The beauty of this recipe lies in its adaptability. Don’t be afraid to get creative based on what you have on hand or what flavors you love most.

Try substituting coconut condensed milk for a dairy-free version. It adds a subtle tropical note and keeps the dessert vegan and lactose-free.

Add a squeeze of lime juice or a bit of lime zest before blending for a tangy twist. The citrus enhances the watermelon’s sweetness and gives the gelato a refreshing edge.

Swap out some of the watermelon for other frozen fruits like strawberries or pineapple. This not only adds depth of flavor but also creates beautiful color variations.

Want a grown-up version? Blend in a splash of vodka or rosé wine before freezing. Alcohol helps keep the texture softer and adds an extra layer of flavor.

If you're watching your sugar intake, try using unsweetened condensed coconut milk and adding a natural sweetener like honey or maple syrup to taste.

No matter how you personalize it, this watermelon gelato is sure to become a summer staple. Have fun experimenting and find the version that’s just right for you!
