- Avoid Overmixing: When making your filling, mix just until combined to keep the berries intact and juicy.

Common Mistakes to Avoid
Making a Blueberry Slab Pie can be simple, but there are a few common pitfalls to avoid to ensure your pie turns out perfectly.
- Incorrect Pie Crust Temperature: Using cold pie crusts can lead to an uneven bake. Ensure your crusts are at room temperature before using them.
- Overfilling the Pie: Adding too much filling can cause the pie to overflow during baking. Stick to about 3 cups of blueberry filling for the best results.
- Skipping the Egg Wash: Not applying an egg wash will result in a dull crust. Brush your crust with a mixture of egg and water for a golden finish.
- Neglecting to Sprinkle Sugar: Skipping the coarse sugar on top means missing out on a delightful crunch. Sprinkle 1-2 tablespoons before baking for added texture.
- Inconsistent Baking Time: Baking for too long or too little can affect texture. Keep an eye on the pie as it bakes for about 30 minutes, adjusting as needed based on your oven.
Storage & Reheating Instructions
Refrigerator Storage
- Store leftovers in an airtight container in the fridge.
- Consume within 3-4 days for optimal freshness.
Freezing Instructions
- Wrap slices tightly in plastic wrap or aluminum foil before placing them in a freezer-safe container.
- You can freeze the pie for up to 3 months.
Reheating Instructions
- Oven: Preheat to 350°F (175°C) and bake for about 10-15 minutes until warmed through. This keeps the crust crispy.
- Microwave: Heat individual slices on medium power for about 30 seconds to 1 minute until warm. This is quick but may soften the crust.
- Stovetop: Place slices in a skillet over low heat, covering it with a lid. Heat for about 5-7 minutes until warmed through.
