Ingredients Notes

The beauty of this 2-ingredient watermelon gelato is in its simplicity. With just two humble ingredients, you get a creamy, refreshing treat that rivals anything from the gelato shop.

Let’s start with the star: watermelon. You’ll need seedless watermelon that’s been cubed and frozen ahead of time. The freezing is crucial – it’s what gives the gelato its icy, scoopable texture without needing an ice cream maker. Choose a ripe, juicy melon for the best flavor; the sweeter your melon, the better your gelato will taste.

The second ingredient is full-fat canned coconut milk. This is what adds the creaminess and richness you’d expect from gelato, without any dairy. Be sure to shake the can before opening, or stir it well to mix the cream and liquid. Lite coconut milk will work in a pinch, but your final product will be a bit icier.

That’s it – just fruit and coconut. You don’t need sugar, but if you find your melon isn’t as sweet as you’d like, a teaspoon of honey or maple syrup can help boost the flavor without overpowering it.

As for equipment, all you really need is a good blender or food processor. A high-speed blender like a Vitamix will give you the smoothest results, but a standard food processor works just as well. Make sure your machine can handle frozen fruit – this mixture is thick!

How To Make This 2-Ingredient Watermelon Gelato

Making this recipe is so simple, it almost feels like cheating. The hardest part is waiting for the watermelon to freeze – after that, the rest is a breeze.

Start by cutting your seedless watermelon into small cubes, roughly 1 to 1.5 inches wide. Spread them out on a parchment-lined baking sheet in a single layer and place them in the freezer. Let them freeze solid for at least 4 hours, but overnight is best. This step ensures your gelato will have that perfect creamy, frozen texture without getting watery.

Once your watermelon is completely frozen, transfer the cubes to your blender or food processor. Don’t overfill the bowl – depending on the size of your machine, you may need to work in batches to ensure a smooth blend.

Add about ⅓ to ½ cup of full-fat coconut milk for every 3 cups of frozen watermelon. Pulse the mixture to get things moving, then blend until completely smooth. You may need to stop and scrape down the sides once or twice. The texture should be thick, creamy, and similar to soft-serve ice cream.

If your mixture seems too thick or isn't blending well, add a splash more coconut milk. Just go slowly – too much liquid and you’ll end up with a smoothie instead of gelato!

At this point, you can either serve the gelato immediately for a soft-serve experience, or transfer it to a lidded container and freeze for another 1–2 hours for a firmer, scoopable texture.

From start to finish (minus freezing time), the blending process takes less than 10 minutes. It’s a fantastic last-minute dessert or a refreshing snack on a sweltering afternoon.

Storage Options

This gelato is best enjoyed the day you make it, but leftovers can be stored in the freezer for later.

Transfer any remaining gelato into an airtight freezer-safe container. For best results, press a piece of parchment paper or plastic wrap directly on the surface before sealing the lid – this helps prevent ice crystals from forming.

Stored this way, your gelato will keep for up to 2 weeks, although the texture will become firmer the longer it sits. For the best experience, let it sit at room temperature for 10–15 minutes before scooping to soften it slightly.

To reheat (or rather, thaw), avoid the microwave. A few minutes on the counter is all it takes to return it to the perfect consistency without melting it into a slushy.

Variations and Substitutions

This recipe is so versatile, you’ll find endless ways to make it your own. The watermelon and coconut milk combo is just the beginning.

For a citrusy twist, add a tablespoon of freshly squeezed lime or lemon juice to the blender. It brightens up the flavors and adds a tangy contrast to the sweetness of the watermelon.

Want a minty refresh? Toss in a few fresh mint leaves with the other ingredients. It’s like turning your favorite watermelon mojito into dessert form – perfect for summer BBQs.

You can also mix in other frozen fruits like strawberries, mango, or pineapple. Keep the total volume of frozen fruit the same, but swap out a portion of the watermelon for a fun flavor change.

If you're looking for a little indulgence, stir in mini chocolate chips or coconut flakes after blending for added texture and a more dessert-like vibe.

And finally, if you’re avoiding coconut or allergic, try using Greek yogurt or almond milk yogurt instead. The flavor and texture will be slightly different, but still deliciously creamy and dairy-free (if you choose a non-dairy option).
