Equipment Needed
- Mixing bowls
- Whisk
- Pie pan
- Pastry cutter or fork
How to Make This Recipe
Step 1 – Make the Pie Crust
In a medium bowl, mix together the flour, sugar, and salt until well combined. Then, add the vegetable oil and milk. Stir them together until the dough comes together. Pat the mixture into a 9-inch pie pan, making sure it covers the bottom and sides evenly.
Step 2 – Preheat the Oven
Preheat your oven to 350 degrees F. This will ensure your pie bakes evenly and properly.
Step 3 – Prepare the Custard Filling
In another bowl, combine the sugar, flour, salt, eggs, and sour cream. Whisk these ingredients together until the mixture is smooth and fully blended.
Step 4 – Assemble the Pie
Add the blueberries to your prepared pie crust. Carefully pour the custard mixture over the blueberries, making sure they are evenly distributed.
Step 5 – Make the Crumb Topping
In a mixing bowl, combine the sugar, brown sugar, and flour for the crumb topping. Cut in the butter using a fork or pastry blender until the mixture resembles coarse crumbs. Sprinkle this topping evenly over the custard layer in the pie.
Step 6 – Bake the Pie
Place the pie in the preheated oven and bake for 50–55 minutes, or until the custard is set and the top is lightly browned. You can check that it’s done when the center reaches 160 degrees F. Once baked, let it cool on a wire rack, then refrigerate until you are ready to serve.

Tips for Perfect Results
To ensure your Blueberry Custard Pie turns out perfectly, keep these tips in mind:
- Make sure your ingredients are at room temperature for the best mixing.
- Don’t skip the cooling step; letting the pie cool completely helps set the custard.
- If using frozen blueberries, there’s no need to thaw them—just add them directly to the crust.
- To prevent the crust from burning, cover the edges with foil if they brown too quickly during baking.
- Experiment with spices like cinnamon or nutmeg in the custard for added flavor.
Flavor Variations
If you want to give your pie a fun twist, here are some ideas:
- Add lemon or lime zest to the custard for a citrusy kick.
- Incorporate a splash of vanilla extract for a warmer flavor profile.
- Try mixing in a handful of nuts for some crunch in the crumb topping.
- Use a different type of sweetener, like honey or maple syrup, in the filling or topping for a different flavor.
What to Serve With This Recipe
This pie can be enjoyed on its own or paired with a few treats. Consider these serving suggestions:
- A dollop of whipped cream for added richness.
- A scoop of vanilla ice cream to balance the tartness of the blueberries.
- Fresh mint leaves on top for a pop of color and freshness.
Storage, Make-Ahead & Leftovers
