Here’s a refreshing watermelon smoothie recipe with strawberry and lime that’s perfect for summertime. Just four simple ingredients to blend and sip to energize your day!

Strawberry Watermelon Smoothie

Are you looking for a refreshing summer beverage? Then I got what you need! I made a strawberry watermelon smoothie that will cool you down in an instant. Have you noticed strawberries in season at the market yet?

There is a fabulous local grocery store walking distance from our home, and they have dozens of flats just showcased out front. They were calling my name, plus the price was good. I also couldn’t resist grabbing a seedless watermelon to cut up and make the smoothie even more delicious.

Eating a juicy watermelon means it’s officially summertime, so let’s not wait a second longer. This mixture has just four ingredients to smoothie bliss, and it’s ready in under 5 minutes. Just grab a straw and sip away, sunshine and sea breezes here we come!

If you don’t have access to ripe berries right now, frozen strawberries will work. The fresh lime and mint opens up your senses and immediately invigorates you. I grabbed a seedless watermelon and chopped it into cubes, tossing any leftovers in the freezer for my next smoothie fix.

Since all of the berries and melons are at the beginning of their season and pretty ripe, it added just the right amount of sweetness to this cold drink. You can use a natural sweetener like agave nectar, honey or maple syrup if you want to please your sweet tooth and balance some of the tartness from the lime juice.

The moment I shared this recipe with my boys, it was hit! My son loves mommy’s smoothie, especially my strawberry banana flavor but I think this may be his new favorite. It has a slushy consistency, so it reminds him of a popsicle or sorbet, but much healthier.

My hubby Jason and I thought of another more fun idea for this smoothie. After that first batch, the next one we got a little more creative to make it adult-friendly. I’m not going to lie; it makes an excellent margarita base. This strawberry watermelon smoothie is going to be your new summer breakfast and snack boost, or happy hour beverage.

What are tips for picking a ripe watermelon?

The first thing is to work your mighty biceps and lift up the watermelon. Regardless of the size, it should feel relatively heavy. Next step is to look for a creamy yellow splotch on the melon where it rested on the ground during harvest. The yellow color indicates ripeness. The last thing is to channel your inner musician and give the bottom of the melon a drum beat “tap.” Ripe watermelons will have a deep hollow sound. The melon may be over or under-ripe if it sounds dull. (Source: The Kitchn)

    Just made this. I cut the recipe in half and used fresh strawberries and whiskey instead of tequila since that’s what we had on hand. Used honey for a little sweetness. I don’t care for really sweet stuff and this is awesomely perfect. Thinking about going back to Wal Mart for more STRAWBERRIES! ?

    We tried the strawberry-watermelon smoothie as an adult beverage. We didn’t have tequila so tried vodka (so-so) and then tried Jim Beam bourbon (yes!) we used maple syrup for the sweetener and added orange juice to the fruit. For the ratios used in your recipe I’d say we added 1/2 to 3/4 cups orange juice. That and the bourbon made for a tasty cocktail!
