1-Ingredient Watermelon Popsicles Recipe

You're in luck here, because this may just be the easiest recipe on the entire website with only one true ingredient. While you need just one food ingredient, you will also need some popsicle molds, plus a blender or food processor to make these at home.

Lacking those, you can simply turn your watermelon into a refreshing watermelon slushie!

Ingredients

You'll need:

• 1 large ripe watermelon

Special Equipment

• 1-2 sets of popsicle molds or reusable freezie tubes
• A blender or food processor.
• 1 mesh strainer

I use my trusty KitchenAid immersion blender to make this recipe easy and mess free! (Plus immersion blenders are MUCH cheaper than a stand blender!)

Instructions

1. Start by cutting the watermelon in half. Take the immersion blender and literally sink it into the ripe watermelon flesh. Hit the go button and puree all the fruit right there in the rind.

Pro-Tip: Blending the melon directly in its rind means you don't have to clean a cutting board or a bulky blender jar. It keeps the cleanup incredibly fast and simple!

2. Once the pulp is fully blended, pour it into the mesh strainer to separate all the liquid from the pulp. Squeeze any remaining juice out of the leftover pulp.

Don't waste the pulp! The strained watermelon pulp can be stirred into morning oatmeal, blended into summer smoothies, or added to your compost pile.

3. Stir the juice to properly mix all the natural fruit juices and then pour it directly into the popsicle molds. Freeze immediately for at least 4-6 hours (or overnight) to ensure they are fully set and hold their shape when unmolded.

4. Pop the watermelon popsicles out and enjoy!

TIP: How to Unmold Your Popsicles easily: If your popsicles are stuck, do not pull hard on the sticks, or you might break them. Instead, run the outside of the plastic mold under warm (not hot) water for 10-15 seconds. This will slightly melt the outer edge and loosen up the popsicles, and they will slide out cleanly.

Texture adjustments

Because watermelon has a high water content, these popsicles freeze quite solid. If you prefer a slightly softer, easier-to-bite texture, you can blend in a tablespoon of liquid sweetener (like honey, agave, or simple syrup) or a splash of lime juice. The sugars and acid help lower the freezing point slightly, yielding a softer texture.

Fun Flavor Variations

The best part about these watermelon popsicles is that they are easy to make and use just one ingredient. That said, you can always add other things to it to keep your summer treats interesting!

Here are a few extra flavors to explore and mix:

• Watermelon-Mint: Stir in a few finely chopped fresh mint leaves after straining.
• Watermelon-Lime: Add a squeeze of fresh lime juice before freezing for a tangy, spicy kick.
• Watermelon-Berries: Add strawberries, blueberries or blackberries. You can either puree them with the watermelon juice or add roughly chopped small pieces of berries to the strained watermelon juice for some extra flavor and texture.
• Other Fruit Juices: Orange or Apple juice work well
• Watermelon-Alcohol: For adults only version, add some rum or vodka to the juice prior to freezing. Just don't add too much, or the popsicles won't set! (alcohol doesn't freeze well)
