- 1/4 teaspoon ground cinnamon

- 6 tablespoons unsalted butter, cold and cubed
Substitutions & Notes:

Equipment/Tools Needed
To make your Blueberry Crumble Pie, you’ll need:
- A 9-inch pie dish
- Mixing bowls (medium and large)
- Measuring cups and spoons
- Pastry cutter or fork (for cutting butter into the crumble)
- Whisk or spatula
- Aluminum foil (optional, for covering edges during baking)
If you don’t have a pastry cutter, two knives or even your fingers can work just fine!
Step-by-Step Instructions
- Preheat the Oven: Start by setting your oven to 375°F (190°C). This ensures it’s ready when your pie assembly is complete.
- Prepare the Filling: In a large bowl, combine the blueberries, granulated sugar, brown sugar, cornstarch, lemon juice, vanilla extract, and cinnamon. Carefully toss the blueberries until they are evenly coated. Set aside.
- Make the Crumble Topping: In a separate bowl, mix the flour, oats, brown sugar, and salt. Incorporate the cold, cubed butter and use a pastry cutter or fork to mix until the mixture forms coarse crumbs.
- Assemble the Pie: Transfer the blueberry filling into your prepared pie dish. Spread it out evenly. Sprinkle the crumble topping over the filling, ensuring an even layer.
- Bake the Pie: Place the pie on the middle rack of your oven. Bake for 45–50 minutes, or until the filling is bubbly and the topping turns golden brown. Cover the edges with aluminum foil if they start browning too quickly.
- Cool Before Serving: Remove the pie from the oven and let it cool on a wire rack for at least 2 hours. Cooling allows the filling to set properly.
- Serve and Enjoy: Slice the Blueberry Crumble Pie and serve it warm or at room temperature. Serve it with a scoop of vanilla ice cream for an extra touch of indulgence.
Pro Tip: If using frozen blueberries, there’s no need to thaw them—just increase the baking time slightly to account for extra moisture.

Expert Tips & Variations
Here are some tried-and-true tips to elevate your Blueberry Crumble Pie:
- Use Fresh Lemons: Fresh lemon juice brightens the flavor of the blueberries without overpowering them.
- Prevent Sogginess: To keep the bottom crust crisp, brush it lightly with beaten egg white before adding the filling.
- Experiment with Spices: Try adding nutmeg or cardamom to the filling for a unique twist.
- Add Nuts to the Topping: Incorporate chopped pecans or almonds into the crumble for added texture.
- Double the Recipe: This pie freezes beautifully, so consider making two—one to enjoy now and one for later.
Common mistakes include overmixing the crumble topping or underbaking the pie. Avoid these pitfalls by working quickly with cold butter and testing the pie’s doneness by checking for bubbling filling.
