Spinach and Watermelon Salad

Yesterday was the Fourth of July, and my oldest daughter had an afternoon picnic with her swim team. We were in charge of taking a watermelon. BUT so were eight other parents. That is a ton of watermelon, and as you can imagine we were sent back home with almost the full watermelon. I was trying to think of something to do with all of it, and then I remembered a fantastic Spinach and Watermelon Salad I had eaten last summer at a restaurant.

We had a few hours until we were going to head to our small town Fourth Of July carnival; so I decided I would make a Spinach and Watermelon Salad as a side for our dinner.

Guys, it was INSANELY delicious and mouthwatering. I am not even kidding. I have always loved watermelon, and just recently shared a Grilled Watermelon recipe with you guys, but so far to date, this Watermelon Salad is my favorite way to enjoy watermelon. So I shot a few pics and wrote down the recipe so I could share it with the world … LOL, but seriously at least a few of you, because it is so good.

The balsamic reduction dressing is so stinking good and helps to make this Spinach and Watermelon Salad taste as good as it does. You could just create the balsamic dressing without reducing the balsamic if you were in a huge hurry, but I highly recommend taking the 15 minutes to make the reduction.

Everything in this fresh summer salad pairs together perfectly. My girls even loved the red onions in this watermelon salad. My five year old always loves red onions, but my thirteen year old usually cannot stand them!

How To Make A Spinach and Watermelon Salad

The full recipe with measurements is in the recipe card at the bottom of this post.

  • Chop up your watermelon, basil, onions, and pecans. The watermelon should be in bite-size cubes. I used a mandoline for the red onions because I wanted them thin. I just tore the fresh basil up with my hands, but chopping is probably easier … haha. And I bought pre-chopped pecans, but if you have whole ones, you will want to chop them.
  • Measure out your balsamic vinegar and pour it into your saucepan. Heat on medium until you reach a simmer, and then reduce your heat to simmer for about 15 minutes. Stir frequently and be careful not to let your sauce burn.
  • While your balsamic is simmering mix all of your other ingredients together.
  • When your balsamic has thickened remove from the heat and stir in your oil and salt.
  • Pour over the spinach and watermelon salad and serve immediately!

The BEST watermelon salad I have ever tasted.

Not only does this spinach and watermelon salad taste amazing, but it also provides several health benefits. I always like to include a few tidbits of health benefits and nutritional information with my recipes (even the ooey gooey dessert recipes like this Paleo Banana Split).

Spinach – Spinach is considered to be one of the healthiest foods on earth, with researchers identifying more than a dozen different types of flavonoid antioxidants alone that are present in spinach, not to mention all of its other nutrients. Spinach nutrition has powerful anti-inflammatory and antioxidant abilities, and if you combine that with its very low amount of calories, it is easily one of the most nutrient-dense foods in existence.

Basil – Basil contains antioxidant-rich volatile essential oils, which are considered hydrophobic. This means they don’t dissolve in water and are light and small enough to travel through the air and the pores within our skin. Basil’s volatile essential oils are what give the herb its distinct smell and taste, but they’re also responsible for the healing benefits of basil.

Side Note – Essential Oils are insanely powerful, and we use them in our family for SO MANY things! Head TO THIS POST if you want to learn more on essential oils.

Watermelon – A low-calorie, hydrating fruit that is a natural high antioxidant food, plus a source of vitamins and minerals that can help fight inflammation, free radical damage and prevent a number of serious illnesses.

Red Onions – Red onions are also a rich source of the flavonoid anti-oxidant quercetin and the polyphenol anti-oxidant anthocyanin.  These anti-oxidants prevent the oxidation of dietary and cellular fatty acids.  They are very powerful free radical scavengers that neutralize cancer cell growth and dramatically reduce whole body inflammation.

Pecans – Although many people claim that a low-fat diet is the best way to live a healthy lifestyle, the healthy fats of pecan nutrition are powerful in the production of antioxidants, reduction of inflammation and simply provide a great-tasting addition to almost any dish.
