Heirloom Tomato Watermelon Salad

This sublimely summer heirloom tomato watermelon salad with basil combines two of my favorites summer treats – watermelon and heirloom tomatoes…

I’m a sucker for heirloom tomatoes. They always catch my eye at the market and they’re always so delicious. Topped with burrata cheese, good olive oil, and some salt and pepper? Maybe a piece of delicious bread. Mm, mm, mmm; I’m in heaven!

Since I try not to eat too much cheese, however, I have to find other ways to enjoy heirloom tomatoes. 

Tomato Watermelon Salad

This recipe is really straightforward and can be made last minute, which is always a plus (especially in the summer when I can’t seem to think too far ahead for food).

I LOVE that tomatoes and watermelon are two fruits (yes, they’re both fruits) that don’t take time to ripen. You can buy both of them at the market and enjoy them right when you get home.

It’s because of this fact that this salad is a bit of a default for weeknight dinners and any occasion where I’m in charge of bring the salad to someone else’s place!

Now that I know how to store tomatoes to last longer too, I’m all over having the recipe on hand (memorized by nows)!

Tomato Watermelon Salad Without Cheese?

Most recipes for tomato watermelon salad have cheese (often feta). While my watermelon arugula salad calls for feta and I think the combination is quite delicious, I just don’t think this salad needs it.

I’m a big proponent of seasonal eating (hence the sustainable magazine of spring & summer recipes). If it’s tomato season and it’s watermelon season, then it’s actually also basil season, AND these flavors need no help in being delicious.

Honestly. The tomato watermelon mixture becomes a salad with the simple addition of delicious olive oil, a tad of vinegar, and some salt and pepper…that’s all you need. Trust me on this one and save the feta for this Greek cornbread recipe!

What does Heirloom Tomato Mean?

Heirloom tomatoes (all heirloom produce actually) are grown from seeds that haven’t been altered, modified, or cross-breeded in at least 50 years.

While many seeds are altered for a number of reasons (shelf-life, color, etc.), heirloom seeds are not – and they often have the best flavor because of it!

There are actually heirloom watermelon varieties as well, but they aren’t too common.

Why does Basil Brown?

I love topping this watermelon salad with basil and pine nuts because it makes it a little more savory – not so sweet. The combination of basil and pine nuts gives a nice pesto flavor occasionally, which is nice.

I always try to multitask while cooking, chopping the garnish while things are cooking, which means I easily forget how delicate basil is until it’s all chopped up.

Once cut, basil leaves start to blacken (I’m supposing oxidation and science are involved here!), so remember not to cut your basil until just before serving or, when making pesto, just before adding it to the blender!

If you’re hoping to do a little bit make-ahead here, you can certainly cut the watermelon and tomatoes ahead of time. If you’re prepping just a couple of hours before serving, you can easily combine the watermelon and tomatoes.

More than just a couple hours, I’d recommend cutting them and storing them separately. The tomatoes will need to be laid flat on a dish or they’ll quickly start to lose their shape.
