A good watermelon salad always makes me think of the Fourth of July. In the past, I’ve always made Ina Garten’s Watermelon and Feta Salad. It’s one of my absolute favorite Ina recipes… which is saying a lot coming from me. With that favorite in mind, I created my Spicy Watermelon and Pickled Onion Salad.

I was also recently eating at one of my favorite Mexican restaurants in town, Jose, and they had a watermelon salad with a ton of pickled ingredients on top. I put the two of these watermelon salads together for an epic, refreshing, and delicious salad. It goes great with any grilled BBQ and it’s a recipe that I know you will just adore!

This was sooo good – such a hit and unique. I realized the title says pickled red onion but it calls for white? White was delish but now wondering which it is or maybe Iโm missing something!
Apologies for the typo! White onion is correct ๐
So pretty and yummy!
So yummy! Brought this to a friends and everyone loved it!
