Traditional blueberry pie gets a tasty twist in this slab pie recipe that’s topped with a cinnamon-y crumble.
Frozen blueberries can be used. Do not thaw, and increase cornstarch to 4 tablespoons.
If crust and crumb topping are browned before filling has had a chance to thicken and bubble, cover with foil for remainder of bake time.
Pie filling will thicken upon standing. For cleaner slices, let pie cool completely, 1 to 2 hours.
