Dice watermelon and place in a freezer safe container. Freeze for 3-4 hours.
Pour rosé into a standard ice cube tray. Freeze for 3-4 hours. Save remaining rosé and place in the refrigerator until ready to use.
Add frozen watermelon, frozen rosé cubes, agave (if using) and remaining rosé in a blender. Process until smooth.
Pour into glasses and serve with a watermelon wedge and paper straw.
- Choose a rosé that is a darker pink to get a good color for your slushie. If you choose a lighter pink then your slushie will just be lighter in color.
- I prefer a rosé on the dryer side, but again I'm not a fan of overly sweet drinks so choose a rosé that you enjoy drinking!
- If you let the frozen watermelon rosé slushie sit for a bit, the watermelon may settle to the bottom. Give it a swirl with your straw to get it to mix back together. Place any leftovers in the freezer until you're ready to serve and give it a quick blend in the blender.
- I used my Vitamix, but you don't need a high powered blender for this recipe. It works great with a normal blender, too!
