Cookbook author and baking expert Julie Hasson loves using her cast iron skillet to bake pie—there's something satisfyingly old-fashioned about it. This pie has no bottom crust, which makes it quick to prepare, perfect for a last-minute dessert. Try it topped with a scoop of ice cream.
5 cups frozen blueberries (don't thaw)
2/3 cup granulated sugar
1/4 cup plus 2/3 cup water
1/4 cup corn starch
Grated zest from 1 lemon
2 ripe medium peaches, peeled, pitted, and sliced
3/4 cup unbleached all-purpose flour
1/2 cup old-fashioned rolled oats (don't use quick cooking)
1/2 cup firmly packed light brown sugar
1 teaspoon freshly grated nutmeg
3/4 cup nonhydrogenated margarine (such as Earth Balance), melted
Ice cream for serving (optional)
How to Make It
Preheat the oven to 400°. Lightly grease a 10-inch cast iron skillet with a little shortening.
Make the filling: In a large saucepan, combine the blueberries, granulated sugar, and 1/4 cup water. Bring to a simmer over medium heat, stirring occasionally.
Whisk together the cornstarch and remaining 2/3 cup water in a small bowl until smooth. Stir the cornstarch mixture into the hot berries. Gently stir in the lemon zest and peaches, being careful not to mash the peaches. Reduce the heat to low and continue simmering the fruit, gently stirring, until the juices have thickened and the mixture is clear. Remove the saucepan from the heat and scoop the mixture into the prepared skillet.
Make the topping: Stir together the flour, oats, brown sugar, and nutmeg in a small bowl. Add the melted margarine, stirring until incorporated. Using your fingertips, work the margarine into the flour mixture, squeezing until nice and crumbly. Sprinkle the topping over the blueberry filling.
Bake the pie just until the topping is nicely browned, 30 to 40 minutes. Serve with ice cream, if you like.
For an all-blueberry version, omit the peaches and increase the blueberries to 6 cups.
Not sure what happened but my topping was not crumbly... The instructions say melted but that seemed wrong to me.. I did it anyway. It was very goopy but since I didn't have anymore ingredients to start over, I slopped it on there. Hope it didn't ruin it. We will see.
