Ingredient Notes

This recipe is all about simplicity, but the two ingredients you choose will make all the difference. Picking the right watermelon and using a quality sweetened condensed milk sets you up for frozen success.

Watermelon is the heart of this gelato. Choose a ripe, seedless variety for the best results. You’ll want to cube and freeze it ahead of time to give the gelato its smooth, scoopable consistency without the need for churning. Look for fruit that feels heavy for its size, with a deep hollow sound when tapped – a classic sign it’s full of juicy goodness.

Sweetened condensed milk provides the creamy richness you expect from gelato, without needing any dairy-heavy custards or complicated steps. Its thick, silky texture and subtle caramel-like sweetness pair beautifully with the watermelon’s brightness.

The balance between the fruit’s natural water content and the condensed milk’s thickness is what gives this treat its magic – no extra sugar, no stabilizers, no problem.

You won’t need much in the way of equipment, either. A good-quality blender or food processor is essential for breaking down the frozen watermelon into a smooth purée. If you have a silicone loaf pan or any shallow freezer-safe container, even better – it helps the gelato freeze more evenly and scoop more easily.

How To Make This 2-Ingredient Watermelon Gelato

Creating this luscious, icy gelato couldn’t be more straightforward. You’ll just need a bit of prep ahead of time – and a little patience while it firms up in the freezer!

Start by prepping your watermelon. Cut it into bite-sized chunks and remove any seeds if necessary. Lay the cubes in a single layer on a parchment-lined baking sheet and freeze until solid – usually about 3 to 4 hours. This step is key to getting that thick, scoopable texture without any added thickeners.

Once the watermelon is frozen, it’s time to blend. Add the frozen cubes to your blender or food processor, followed by the sweetened condensed milk. Pulse several times to break up the watermelon, then blend until completely smooth. You might need to stop and scrape down the sides a few times to ensure everything blends evenly.

If your blender is having trouble, let the watermelon sit for a minute or two to slightly soften. Don’t add any extra liquid – the watermelon will break down beautifully on its own with a bit of patience.

Pour the mixture into a loaf pan or shallow container. Smooth the top with a spatula, then cover with plastic wrap or a tight-fitting lid. Freeze for 4–6 hours or until firm enough to scoop.

When you're ready to serve, let the gelato sit at room temperature for 5–10 minutes. This softens it just enough to give you those perfect creamy scoops. It’s like biting into a cloud of summer.

Storage Options

This gelato is best enjoyed within the first few days of making it, but it stores well for up to 2 weeks in the freezer. Be sure to keep it tightly covered to prevent ice crystals from forming – a layer of plastic wrap pressed against the surface can help preserve its creamy texture.

Store it in a freezer-safe container with a tight-fitting lid. A loaf pan covered in plastic wrap and foil also works in a pinch.

When scooping from the freezer, let the gelato rest at room temperature for 5–10 minutes to soften slightly. This makes it easier to serve and brings out more of that fresh watermelon flavor.

Avoid repeated thawing and refreezing, which can cause the texture to become icy rather than creamy.

Variations and Substitutions

One of the best parts of this recipe is how versatile it is. You can switch up flavors, tweak the texture, or add your own twist depending on what you have on hand or what you're craving.

Try using coconut condensed milk for a dairy-free option that still offers richness. It brings a tropical vibe that pairs beautifully with the watermelon.

You can also blend in a handful of fresh mint leaves for a bright, cooling touch. Mint and watermelon are a classic combo, and this adds a subtle herbal note that’s super refreshing.

If you're in the mood for a tart twist, add a tablespoon or two of lime juice before blending. The citrus sharpens the watermelon’s sweetness and keeps the flavor light and zingy.

Want to make it boozy for a grown-up treat? A splash of vodka or rum (about 1 tablespoon) won’t change the taste much, but it will make the gelato slightly softer and easier to scoop.

Don’t be afraid to get creative! Add a swirl of berry purée, toss in mini chocolate chips before freezing, or experiment with other frozen fruits like mango or pineapple for a tropical medley.
