How to Make Blueberry Slab Pie
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). This ensures your pie bakes evenly from start to finish.
Step 2: Prepare the Pie Crusts
Place two of the uncooked pie crusts on a baking sheet. Overlap them slightly if necessary. Roll out the third crust separately so you can create a lattice top later.
Step 3: Make the Filling
In a mixing bowl:
1. Combine the fresh blueberries with powdered sugar, cornstarch, vanilla paste, lemon zest and juice, and ground cinnamon.
2. Mix gently until all berries are coated.
Step 4: Assemble the Pie
Pour the blueberry mixture into the prepared crusts on the baking sheet:
1. Spread it evenly across the bottom layer.
2. Use strips from the rolled-out third crust to create a lattice design on top of your filling.
Step 5: Apply Egg Wash
In a small bowl:
1. Whisk together one egg with one tablespoon of water.
2. Brush this mixture over the lattice top for that golden finish.
Step 6: Sprinkle Coarse Sugar
Sprinkle coarse sugar over the top of your pie before placing it in the oven. This adds sweetness and crunch!
Step 7: Bake Your Slab Pie
Bake in your preheated oven for about 30 minutes or until the crust is golden brown and bubbly.
Once baked, allow cooling slightly before serving. Enjoy your delicious Blueberry Slab Pie!

Common Mistakes to Avoid
Making a Blueberry Slab Pie can be simple, but avoiding common mistakes is crucial for the best results.

- Overfilling the pie: Too much filling can cause overflow during baking. Stick to about 3 cups of filling for best results.
- Not using fresh blueberries: Fresh berries enhance the flavor and texture. Frozen blueberries can result in a soggy pie.
