Roll out the pie crust on a lightly floured surface and fit it into the pie pan or tart pan. (try this buttery crust recipe)
In a medium bowl, combine the milk (or heavy cream), beaten eggs, sugar, and flour
Whisk until a pale creamy texture forms
Arrange the strawberry halves in the prepared pie crust
Pour the custard mixture over the strawberries, spreading it evenly, filling empty spaces
Sprinkle the top of the pie with the cubed butter
Place a baking sheet under the pie plate to catch any drips
Bake the pie in the preheated oven for 45-60 minutes, Check at 30 minutes and then every 10 minutes until the custard is set. Use a pie shield to prevent burning
Remove the pie from the oven and let it cool to room temperature on a wire rack. The hot custard should jiggle but not be runny.
This is optional but if you want the strawberries to regain some juicy-ness, brush the top of the strawberries with some strawberry jam
Cover with a lid and refrigerate for at least 2 hours before serving.
Top the pie with whipped cream or ice cream if desired.
Slice and serve!
Notes
It needs to stay refrigerated after cooling otherwise it will get soupy. Take the pie out to serve and place it back in the refrigerator.
