Start with a perfectly baked pie crust—either homemade or store-bought. Pre-bake it until lightly golden and completely cool before filling.
Gently rinse 3 pounds of fresh strawberries under cool water. Pat dry carefully, hull by removing green tops and damaged spots, then slice into halves or quarters.
In a large bowl, combine ½ cup sugar, 2 tablespoons cornstarch, 1½ teaspoons Sure-Jell, a pinch of salt, and 1 tablespoon lemon juice. Whisk until uniformly blended.
Add the sliced strawberries to the bowl with the dry mix. Gently fold the strawberries until evenly coated, ensuring berries remain whole and juicy.
Pour the strawberry mixture into the pre-baked pie crust, spreading evenly. The thickening agents will help the pie set as it chills.
Cover the pie with plastic wrap and refrigerate for at least 4 hours or overnight to allow the filling to set fully with a glossy finish.
Once chilled and set, slice and serve as is or with whipped cream or vanilla ice cream for an indulgent treat.
