In a medium saucepan, combine 4 cups frozen strawberries, ¾ cup granulated sugar, 3 Tablespoons cornstarch, and ½ cup water.
Place over medium heat and cook, stirring frequently, until the strawberries begin to break down and release their juices (about 5–7 minutes).
Continue cooking until the mixture thickens and becomes glossy, about 2–3 more minutes.
Remove from heat and stir in 1 Tablespoon fresh squeezed lemon juice, 1 teaspoon vanilla extract, and a pinch of salt.
Let the filling cool for 10–15 minutes, then pour into 1 (9-inch) pie crust, baked and cooled
Smooth the top and refrigerate for at least 3–4 hours, or until fully set. Overnight is best.
Slice and serve chilled with whipped cream or whipped topping and fresh strawberries, if desired.
Notes
Please refer to my FAQ’s (Frequently Asked Questions) and ingredient list above for other substitutions or for the answers to the most common questions.
I just purchased a 9-inch frozen pie crust and baked it to the package directions (poking holes with a fork to keep the crust from rising up too much.) You can also use your favorite Homemade Pie Crust recipe but you will also need to bake it off first before adding the strawberry filling.
