Combine the strawberries and sugar in a food processor. Process until almost smooth, about 30 seconds.
Transfer the strawberry purée to a medium bowl. Stir in the Greek yogurt and vanilla. Taste and add more sugar, if desired.
Serve immediately with fruit for dipping or cover and chill for up to 1 week.
Notes
Simple swap--Got vanilla Greek yogurt on hand? Use it and skip the extra vanilla.
Adding sugar--The sweetness of your dip will depend on how ripe your strawberries are. The recipe is written based on using very ripe summer strawberries. If yours aren't quite as sweet, stir in extra sugar to taste once you've made the dip. Keep in mind that the fruit you use to dip will also be sweet.
Storage--Store the strawberry fruit dip in a sealed container or jar in the fridge for up to 1 week. Stir well before serving.
Dietary--This recipe is suitable for gluten-free and vegetarian diets.
