Preheat oven to 450°F. Unroll the crust into a 9-inch pie plate. Trim the edge. Line the unpricked crust with a double-thickness heavy-duty aluminum foil. Bake the crust for 8 minutes. Remove the foil and bake the crust for an additional 5 minutes. Remove the crust from the oven and cool on a wire rack.
In a small saucepan, combine the sugar, cornstarch, and water until smooth. Bring the mixture to a boil; cook and stir until thickened, about 2 minutes. Remove the pan from the heat and stir in the gelatin until completely dissolved. Refrigerate the gelatin mixture until slightly cooled, about 15-20 minutes.
Meanwhile, arrange the strawberries in the crust. Pour the gelatin mixture over the strawberries. Refrigerate until set.
If desired, serve with whipped cream.
Notes
I one-hundred percent recommend letting your pie set up for 8 hours minimum. Some recipes call for as little as 2, but I don’t think the filling “sets” right unless you leave it in the fridge overnight.
