Ingredients Notes

The beauty of this gelato is in its simplicity, but each ingredient plays a key role in getting that dreamy, scoopable texture and natural sweetness just right.

Watermelon is the heart of this recipe. You'll want to use ripe, seedless watermelon for the smoothest result. Look for one that feels heavy for its size with a deep yellow field spot — that’s your cue it’s juicy and sweet. Cut it into cubes and freeze them in a single layer before blending for best results.

Sweetened condensed milk is the secret to that silky gelato texture. Its thick, syrupy consistency balances the icy watermelon and adds just enough creaminess without needing dairy cream. Plus, it keeps the texture soft and scoopable straight from the freezer — no churning required.

There’s no need for added sugar, flavoring, or dairy. The watermelon provides freshness and hydration, while the condensed milk adds smoothness and richness.

If you’re working with a whole watermelon, cube and freeze extras to use for your next batch. They’ll keep well in a freezer-safe bag and save you time later.

No special equipment is needed — just a high-powered blender or food processor. A silicone loaf pan or freezer-safe container is ideal for storing the gelato until it's time to serve.

How To Make This 2-Ingredient Watermelon Gelato

Making this gelato couldn't be easier, but the key is using frozen watermelon cubes. Start by cutting your seedless watermelon into chunks and spreading them on a parchment-lined baking sheet. Freeze them for at least 4 hours, or until solid.

Once the watermelon is completely frozen, transfer it to a high-speed blender or food processor. Don’t overload the container; work in batches if needed. Pulse until the watermelon breaks down into small bits, then blend until smooth. You may need to scrape down the sides a few times to keep things moving.

Next, pour in your sweetened condensed milk. Use about half a cup per four cups of frozen watermelon, adjusting to taste. Blend again until the mixture becomes creamy, thick, and well combined. It should look and feel like soft-serve ice cream at this stage.

If you like a soft-serve consistency, you can enjoy it right away! For a firmer, scoopable texture, transfer the gelato to a loaf pan or shallow container and freeze for another 2-3 hours.

Once frozen, let it sit at room temperature for 5-10 minutes before scooping. It’ll be perfectly creamy and scoopable — no ice cream maker required.

From start to finish (including freeze times), you’re looking at about 6 hours total — most of which is hands-off. It’s a low-effort, high-reward recipe that’s just right for lazy summer days.

Storage Options

This watermelon gelato stores beautifully in the freezer, making it great for prepping ahead. Simply pour the blended mixture into an airtight container or loaf pan, cover tightly with plastic wrap or a lid, and freeze.

It will keep well for up to 2 weeks, although the texture is best within the first few days. Because it’s made with fruit, you may notice some ice crystals form over time — but giving it a few minutes to soften before scooping usually does the trick.

For best results, use a container with a flat surface and press a piece of parchment or wax paper directly against the gelato before sealing. This helps prevent freezer burn and keeps the top layer smooth.

When you're ready to serve again, let it thaw slightly at room temperature for 5–10 minutes, then scoop and enjoy. A warm ice cream scoop helps cut through it if it’s extra firm.

Variations and Substitutions

One of the best things about this watermelon gelato is how easy it is to customize. With a frozen fruit base, the possibilities are endless.

Try swapping out watermelon for mango, pineapple, or strawberries to create different fruity flavors using the same basic formula. Just freeze the fruit beforehand and blend with the sweetened condensed milk.

If you're avoiding dairy, you can experiment with coconut condensed milk for a tropical, vegan-friendly version. It adds a subtle coconut flavor that pairs beautifully with watermelon or pineapple.

Want to add a little zing? A squeeze of lime juice or a sprinkle of tajin or chili powder brings a spicy-sweet twist that’s totally addictive.

For an adult twist, try blending in a splash of rosé or rum before the final freeze. It won’t freeze solid, but it makes an amazing soft sorbet for summer gatherings.

Once you’ve mastered the basic version, don’t be afraid to play. This 2-ingredient watermelon gelato is a blank canvas for your warm-weather cravings — cool, creamy, and endlessly customizable.
