Let’s dive into why this recipe is about to become your warm-weather staple.

Now that you're excited, let’s take a closer look at what you’ll need.

Ingredients Notes

This recipe is all about simplicity, so the ingredients are few but impactful. The real magic happens when these two come together and freeze into something extraordinary.

The star of the show is fresh watermelon. Seedless is ideal, and you’ll want to dice it into chunks before freezing. The natural sugars in ripe watermelon not only provide sweetness but also help the gelato maintain a creamy texture once blended. Be sure to use a watermelon that’s deep red and juicy for the best flavor.

The second essential component is sweetened condensed milk — or for a vegan version, sweetened condensed coconut milk. This adds creaminess and richness without the need for traditional dairy. Its syrupy consistency blends perfectly with frozen watermelon to create that dreamy gelato texture.

If you're watching your sugar intake, you can opt for an unsweetened condensed milk alternative and adjust the flavor with a touch of honey or agave syrup. But honestly, with a sweet watermelon, you may not need much else!

No fancy appliances required here. A standard high-speed blender or a good-quality food processor does the trick. You’ll also need a freezer-safe container to store the finished gelato (if it lasts that long).

How To Make This 2-Ingredient Watermelon Gelato

Making this gelato is as easy as it gets. All it takes is a little prep, a quick blend, and a bit of patience while it firms up in the freezer.

Start by chopping your seedless watermelon into small cubes. Spread them out on a parchment-lined baking sheet and freeze until solid — this usually takes about 2–3 hours. Freezing them individually prevents clumping and makes blending much easier.

Once the watermelon chunks are fully frozen, add them to your blender or food processor, along with ½ cup of sweetened condensed milk per 4 cups of frozen watermelon. You might need to pulse a few times to get it going. Scrape down the sides as needed, and blend until smooth and creamy.

The texture at this point should resemble soft-serve — you can eat it immediately if you like it that way. For a more scoopable, firm consistency, transfer the mixture to a container and place it in the freezer for another 2–3 hours.

When ready to serve, let the gelato sit on the counter for a few minutes to soften slightly before scooping. The final result is light, luscious, and absolutely packed with watermelon flavor.

From start to finish, the entire process (excluding freezing time) takes less than 10 minutes. It’s the perfect last-minute dessert for hot days, BBQs, or just because.

Storage Options

If you happen to have leftovers (though I doubt you will!), this gelato stores beautifully. Keep it in an airtight container in the freezer for up to 2 weeks. For best results, press a piece of parchment paper or plastic wrap directly onto the surface before sealing — this helps prevent ice crystals from forming.

When you're ready to enjoy it again, let the container sit at room temperature for 5–10 minutes before scooping. This will give the gelato time to soften and return to its creamy texture.

Avoid repeated thawing and refreezing, as it can make the texture icy. Instead, scoop what you need and return the rest to the freezer quickly.

Variations and Substitutions

One of the best things about this gelato is how adaptable it is. Once you’ve mastered the basic method, the flavor possibilities are endless.

Want to add a tropical twist? Try blending in a handful of frozen pineapple chunks with the watermelon. The sweet-tart combo is pure sunshine in a bowl.

For a citrusy kick, add a squeeze of fresh lime juice or a bit of lime zest to the blender. It cuts through the sweetness and adds a refreshing brightness.

If you're feeling indulgent, swirl in some mini chocolate chips or dark chocolate chunks after blending. Chocolate and watermelon might sound strange, but the combo totally works.

You can also experiment with different sweetened condensed milk alternatives — like oat-based or almond-based varieties — to suit your dietary needs or taste preferences.

Don’t be afraid to play with this one. The beauty of this recipe lies in its flexibility and fun. Let your creativity shine and make it your own!
