- Make your own crust: Homemade pie crust can elevate your slab pie. It’s easier than you might think and tastes far superior to store-bought options.
- Don’t skip the cornstarch: This thickening agent helps prevent a runny filling. It ensures that each slice holds its shape beautifully.
- Zest your lemon: Adding lemon zest enhances the overall flavor profile by adding brightness and depth to the filling.
- Brush with egg wash: An egg wash gives your crust a shiny, golden finish while keeping it crispy. Mix with water for best results.
- Chill before baking: Allowing the assembled pie to chill in the refrigerator before baking helps firm up the filling and maintain structure.

Common Mistakes to Avoid
Making a Blueberry Slab Pie can be simple, but there are common pitfalls that may affect your results. Here are some mistakes to watch out for:
- Skipping the chill: Not chilling your pie crust can lead to a soggy bottom. Always refrigerate your crust before using it.
- Overfilling the pie: Adding too much filling can cause the pie to overflow. Stick to about 3 cups of filling for best results.
- Ignoring egg wash: Neglecting to brush your crust with egg wash can result in a dull appearance. Always apply an egg wash for a beautiful golden finish.
- Using stale ingredients: Old ingredients can affect flavor and texture. Ensure all your ingredients, especially baking powder and spices, are fresh.
- Not letting it cool: Cutting into your pie too soon can make it messy. Allow the pie to cool completely before slicing for neat pieces.
