Ingredients Notes

The beauty of this 2-Ingredient Watermelon Gelato lies in its simplicity. Every bite showcases the fresh, vibrant flavor of summer's favorite fruit, balanced by a creamy sweetness.

The star of the show is, of course, watermelon. For best results, choose a seedless, ripe watermelon that's heavy for its size and has a creamy yellow spot on its underside—signs of peak ripeness. The sweeter your melon, the better your gelato will taste.

The second essential ingredient is sweetened condensed milk. This thick, rich milk adds both sweetness and creaminess, giving the gelato its luscious texture. Make sure to use the full-fat version for the creamiest results, as low-fat varieties may result in an icier texture.

While not strictly necessary, a good quality blender or food processor is very helpful in achieving a smooth puree. A high-speed blender can break down the watermelon into a silky mixture that freezes beautifully.

If you want to elevate the flavor slightly, you can add a splash of fresh lime juice or a handful of mint leaves to the blend. These optional additions bring a bright, refreshing note to the gelato without complicating the simple recipe.

You'll also need a freezer-safe container with a tight-fitting lid for freezing and storing your gelato. A shallow, wide container works best, allowing the mixture to freeze more evenly and making scooping easier.

How To Make This 2-Ingredient Watermelon Gelato

Creating this delightful watermelon gelato couldn't be easier. Let me guide you through the simple process.

Start by cutting your watermelon into bite-sized cubes, removing any stray seeds as you go. You’ll need about four cups of cubed watermelon for a standard batch, but you can easily scale the recipe up or down depending on how much you want to make.

Next, spread the watermelon cubes in a single layer on a parchment-lined baking sheet and place them in the freezer. Freezing the cubes before blending helps achieve that creamy, scoopable texture reminiscent of gelato.

Once the watermelon cubes are completely frozen—this usually takes about 3-4 hours—transfer them to your blender or food processor. Add one can of sweetened condensed milk right on top of the frozen cubes.

Now it's time to blend. Start on a low setting and gradually increase the speed. You may need to stop and scrape down the sides a few times to ensure everything blends evenly. After a couple of minutes, you’ll have a thick, creamy mixture that resembles soft serve.

Transfer the blended gelato into your freezer-safe container, smoothing the top with a spatula. Cover it tightly and freeze for at least 2-3 hours to allow it to firm up to a true gelato consistency.

When you're ready to serve, let the gelato sit at room temperature for about 5 minutes to soften slightly for easier scooping. You'll be rewarded with a smooth, creamy texture that melts perfectly on the tongue.

Storage Options

This 2-Ingredient Watermelon Gelato stores beautifully, making it perfect for make-ahead desserts. Keep the gelato in a freezer-safe, airtight container to prevent freezer burn and preserve its fresh flavor.

You can store the gelato in the freezer for up to two weeks. After that, the texture may start to change slightly, becoming icier as ice crystals form.

If you prefer to portion the gelato, you can freeze individual servings in small containers or silicone molds. This makes it easy to grab a single serving whenever the craving strikes.

To reheat—well, you won’t actually reheat it, but if the gelato is too hard straight from the freezer, simply let it sit on the counter for 5-10 minutes. The edges will soften first, making scooping much easier.

Variations and Substitutions

One of the best things about this recipe is how adaptable it is. You can easily tweak the ingredients to suit your preferences or dietary needs.

For a dairy-free version, substitute full-fat coconut milk or a dairy-free sweetened condensed milk alternative. The coconut flavor pairs beautifully with watermelon for a tropical twist.

If you want to reduce the sweetness, you can use less sweetened condensed milk. Start with half a can, blend, and taste. You can always add more if needed to achieve your desired level of sweetness.

For an extra flavor boost, try adding fresh lime zest or a tablespoon of lime juice to the blend. The citrus brightens the watermelon’s natural flavor and gives the gelato a slightly tart edge.

You can also experiment with other fruits. Substitute part of the watermelon with frozen strawberries, mango, or pineapple for a fruity fusion. Just make sure to maintain the frozen fruit ratio for the right consistency.

Finally, if you're feeling adventurous, consider adding a small handful of mini chocolate chips or shredded coconut after blending for a bit of texture and surprise in every bite.

Don’t be afraid to experiment and make this recipe your own. With such a simple base, the possibilities are endless, and you might just stumble upon your new favorite frozen treat.
