Bake the pie crust according to package instructions; set aside to cool.
In a saucepan, combine the sugar, cornstarch and water whisk until smooth. Bring to a boil; cook and stir until thickened, about 2 minutes. Remove from the heat; whisk in gelatin until dissolved. Refrigerate until slightly cooled, 15-20 minutes.
Meanwhile, arrange strawberries in the baked crust. Pour gelatin mixture over the berries.
Refrigerate until set about 2 hours. Serve with whipped cream if desired.
