Let the good times roll! It’s summer. The weekends are lazy and relaxed. And, the watermelon is sweet.

Who can resist sitting on the porch and savoring summer with watermelon flavored Italian Ice? 

As a matter of full disclosure, the pictures below are for a half batch of this recipe. We go big when we buy watermelon so we can eat it in slices, make Watermelon Salad with Basil, Feta and Balsamic Syrup or finely dice some pieces to put in a Fancy Salad with Fennel.

The basic recipe has just 3 ingredients and the PERFECT recipe for any age to enjoy making. It doesn’t require an ice cream maker. Just a blender, fork and a little patience while it freezes.

How to Make Watermelon Granita Step-by-Step Tutorial

1 – Purchase the perfect watermelon and cut it into cubes.

Confession: I used to buy watermelon already cut in half and sometimes even cubed. As much as I LOVE watermelon, I wanted to see what it looked like on the inside before committing. Not earth-friendly or frugal.

Fifteen Spatulas does a good job of explaining How to Pick a Superstar Watermelon and touches on cutting watermelon into cubes.

2 – Cut the watermelon into cubes and add them along with some sugar and lime juice to a blender and puree until smooth. 

Use as much or as little sugar as you would like. I settled on an amount that is pretty sweet and still retains the natural watermelon taste, which is already quite sweet! I’ve seen honey used instead. Start with about 2 Tablespoons and then adjust to taste.

3 – Pour the puree into a shallow baking dish so that it is a thin layer that will freeze quickly.

The mixture pictured is about 3/4 inch thick.

4 – After about two hours, rake the mixture with a fork and then put it back in the freezer for at least another hour.

You can play around with the timing a bit.

That is, freeze one hour, then for two or rake every hour. But, “three” seems to be the magic number.

While you’re waiting, kick back and enjoy the scenery. This owl appeared out of nowhere one evening while I was waiting for some watermelon granita to freeze. Really!

5 – Rake again just before serving!

That’s a little bit of lime zest sprinkled on top of the watermelon granita.

How long does Watermelon Granita last in the freezer?

Store Watermelon Granita in a covered container in the freezer. If consistently stored in 0° Fahrenheit freezer, it will be safe to eat forever (according to the USDA Freezing and Food Saftey Guidelines). For quality purposes, it’s usually best to enjoy within 2-3 months of freezing.

It’s the perfect make-ahead dessert. Fluff with a fork just before serving.

  1. I made this for the kids tonight as a treat after pizza night! They loved it and I was so much happier feeding them this than a store bought ice cream loaded with goodness knows what. The lime zest was the best touch!!!
    I’m wondering if I can splash a little vodka over for an adult treat 😉

  2. I was looking for a way to use up some watermelon and came across this recipe. So good! I will definitely make again.
