Place the frozen strawberries, torn basil leaves, lime juice, water, and honey into your blender.
Blend on high speed until the mixture is smooth and icy, with no visible chunks, about 30-45 seconds.
Check the texture — it should be thick, slushy, and scoopable. If it's too thick, add a splash more water and blend briefly.
Taste the slushie and add more honey or lime juice if desired, then give it a quick blend to incorporate.
Pour the chilled strawberry basil lime slushie into glasses, letting the vibrant pink color fill the cups.
Serve immediately with a sprig of basil or a lime wedge for garnish, enjoying the refreshing burst of flavors.
