First of all, it’s ridiculously simple. All you need is ripe watermelon and a can of coconut milk – that’s it! No fancy tools or tricky techniques required, just a blender and a little patience while it freezes.

Once you try this, you’ll be inspired to experiment with other fruit combinations – but watermelon is always a winning start.

Ingredient Notes

This gelato relies on two simple, wholesome ingredients that come together to make something truly special. When your ingredient list is this short, the quality really matters – here’s what to keep in mind.

The star of the show is, of course, watermelon. You want it to be ripe, juicy, and seedless. A good rule of thumb is to look for watermelon with a deep red color and minimal white streaking. If you're cutting it fresh, remove any black seeds before freezing. The sweetness and texture of your fruit will make or break this recipe, so go for the best melon you can find.

Next up is full-fat canned coconut milk. The fat content gives the gelato its signature creaminess without any dairy. Make sure to shake the can well before opening, or stir it to incorporate the cream and liquid. Light coconut milk will still work, but the texture won’t be as rich or satisfying.

You don’t need to add sugar, but if your watermelon isn’t as sweet as you'd like, you can toss in a touch of honey or maple syrup. This is totally optional, and most of the time, the fruit does all the sweetening naturally.

For tools, you’ll need a blender or food processor, a freezer-safe container, and a little freezer space. If you want soft-serve style texture, you’ll also need a spoon and about 10 minutes of softening time before serving.

How to Make This 2-Ingredient Watermelon Gelato

Creating this icy treat is about as easy as it gets – and yet the result is so satisfying, it feels like magic. Here’s how to bring it together.

Start by cutting your seedless watermelon into small chunks, removing any black seeds if necessary. Place the chunks in a single layer on a parchment-lined baking sheet and freeze them until solid – at least 4 hours, or ideally overnight. This step is key for that smooth, gelato-like consistency.

Once your watermelon chunks are frozen solid, transfer them to a high-powered blender or food processor. Let them sit at room temperature for 5 minutes to soften just slightly – this helps the blending process go more smoothly and avoids overworking your machine.

Pour in your full-fat coconut milk – start with about ½ cup, then add more as needed to get the creamy texture you want. Blend on high, stopping to scrape down the sides as needed, until the mixture is completely smooth and thick, like soft-serve gelato.

At this point, you can either serve it right away for a soft, scoopable gelato, or transfer it to a freezer-safe container and let it firm up for 1–2 hours for a more traditional texture. If frozen longer, let it sit out for 10 minutes before scooping to soften slightly.

From start to finish, the active time is only about 10 minutes – the rest is just waiting for it to freeze. Perfect for prepping ahead or whipping up on a whim.

Storage Options

This watermelon gelato keeps beautifully in the freezer, making it great for make-ahead dessert plans or quick sweet cravings.

Store any leftovers in an airtight container in the freezer. I like to press a piece of parchment paper directly against the surface to prevent ice crystals from forming.

It’s best enjoyed within 1 week, as the texture can become icy over time due to the high water content in watermelon. That said, it’s rare for a batch to last that long in our house!

To serve, let the gelato thaw at room temperature for 10–15 minutes before scooping. This helps soften it up and brings back that silky, gelato-like consistency.

For fun and convenience, you can also freeze the mixture in popsicle molds – no scooping required and they’re a hit with kids!

Variations and Substitutions

This recipe is a dream base for endless summer-inspired twists. With just two ingredients, it leaves plenty of room for creativity.

You can swap out watermelon for other high-water content fruits like mango, strawberries, or peaches. Just make sure to freeze the fruit chunks the same way before blending for that luscious texture.

Want a tropical vibe? Add a few chunks of pineapple to the mix or a squeeze of lime juice for brightness. The lime especially cuts through the sweetness and adds a nice tangy finish.

To make it even creamier, you could blend in half a banana or a splash of vanilla extract. These small additions elevate the flavor without complicating the recipe.

Prefer a more decadent take? Drizzle in some honey or toss in a few mini chocolate chips or shredded coconut before the final freeze for added texture and flair.

Don’t be afraid to play around and find your perfect combo. This recipe is as forgiving as it is fun – once you’ve made it once, you’ll start dreaming up new ways to enjoy it all summer long.
