What is in Blueberry Crumble Pie?
A blueberry crumble pie is like the love child of a conventional pie and a berry crisp. We have made this easily using a store-bought crust. I like the ones from the dairy section much more than the frozen pie shells. By all means, though, if you would like to make the pie crust, please do. Here is our recipe for a great pie crust recipe.
You can serve the pie when it is cooled completely, at room temperature, or slightly warm still.
Ingredients
Filling
Blueberries (fresh or frozen) – Fresh blueberries from the market or ones that you actually have picked are, of course, the very best, but frozen berries are at their perfection when they are frozen too.
White sugar – I haven’t tried this with anything but white granulated sugar. It seems to work the best for me.
All Purpose flour – This binds the blueberries together so that they aren’t a sloppy mess but a lovely filling.
Lemon – Lemon pairs gorgeously with blueberries. It makes the pie filling come alive with flavor.
Store-bought pie shell – Let’s make life a little easier by buying a store-bought pie crust; get one in the dairy, not the freezer section. They are the best, I think, but you can always make a homemade pie crust too.
Crumble Topping
Brown sugar – Brown sugar adds more flavor to the topping than white sugar would.
All Purpose flour – The flour and butter holds the crumble together but don’t pat it down too much but keep it light and fluffy for cutting.
Rolled oats, quick cooking – The quick-cooking oats are what is needed for the crumble topping; they are better suited as they are smaller than rolled oats.
Cinnamon – The cinnamon adds a lovely flavor; this though can be omitted.
Butter, cold – The butter holds all the ingredients together and gives the crumble the buttery goodness that it needs.
How to Make Blueberry Crumble Pie
Preheat the oven to 350 degrees F.
Follow the instructions on the pie shell and place it in a 9-inch pie plate; deep dish is preferred using pie weights, rice, or beans.
Zest the lemon and then squeeze the juice from half the lemon.
In a large bowl, combine the blueberries, white sugar, lemon zest, 1 Tbsp of lemon juice, and 3 Tbsp of flour. Toss to coat the blueberries.
Place the blueberry mixture into the prepared pie shell.
To make the crumble topping combine in a large bowl the brown sugar, flour, rolled oats, cinnamon, and butter.
Cut in the butter until crumbly; your butter should be about the size of peas.
Press the topping GENTLY over the blueberry mixture.
Place a baking sheet under the pie plate to catch any dripping, and bake in the preheated oven for 55 – 65 minutes. Bake until the top is golden brown and there are areas where you see the berries are bubbling.
Recipe Pro Tips!
You want to make sure that the flour is cooked and that the blueberries have broken down and are also cooked. It is better to cook this crisp a little longer than not enough.
If you are using frozen blueberries, you will need to cook this crisp longer. I would suggest adding up to 20 minutes to the baking time. If the topping begins to brown, place a piece of foil loosely over the top and continue to bake. The pie should be bubbly in a few places around the pie, especially the edges; this shows you the fruit is cooking or cooked.
There is a load of delicious buttery, crispy crumb topping for this pie, but don’t pack it down too much; you need it crumbly and not like a cookie.
Serve this delicious pie with a scoop of vanilla ice cream or whipped cream to bring it up to the next level of goodness.
To store, I put mine in the refrigerator covered in plastic wrap and then let it warm to room temperature before serving.
