There’s something magical about a classic custard pie. This Blueberry Buttermilk Pie is the perfect harmony of rich, tangy, and sweet, all nestled in a buttery crust. What I adore most is how the fresh blueberries float to the surface as it bakes, transforming into gorgeous, jammy jewels bursting with flavor. This recipe is generous enough for a deep-dish pie, creating a truly satisfying slice. Like a classic cheesecake, it might develop a few cracks on top as it cools—don’t worry! I think it only enhances its rustic, homemade charm. It’s a simple, elegant dessert that feels both nostalgic and special.
Ingredients
• 1 pre-baked 9- or 10-inch Sweet Piecrust
• 1 cup buttermilk
• 1 cup heavy cream or half-and-half
• 4 large eggs
• 2 large egg yolks
• 1/2 cup granulated sugar
• 1 pinch salt
• 1 teaspoon vanilla extract
• 1 cup fresh blueberries
Instructions
1. Prepare the Crust: Pre-bake your pie crust according to its recipe directions. Once baked, reduce the oven temperature to 350°F (175°C) and let the crust cool slightly on a wire rack.
2. Warm the Dairy: In a small saucepan, gently heat the buttermilk and cream over medium-low heat until it is steaming but not boiling.
3. Mix the Base: In a separate large bowl, whisk together the 4 whole eggs, 2 egg yolks, sugar, salt, and vanilla extract until smooth and combined.
4. Temper the Eggs: While whisking continuously, slowly and gradually pour the hot buttermilk mixture into the egg mixture. This tempering process prevents the eggs from scrambling.
5. Assemble the Pie: Pour the custard filling into the slightly cooled, pre-baked pie crust. Evenly scatter the fresh blueberries over the top; they will float as it bakes.
6. Bake the Custard: Carefully place the pie in the preheated oven. Bake for 35 to 45 minutes, or until the edges are set but the center still has a slight jiggle. The pie will continue to set as it cools.
7. Cool and Chill: Remove the pie from the oven and let it cool completely to room temperature on a wire rack. Once cooled, cover and transfer to the refrigerator to chill for at least 2 hours before serving.

Pro Tips
• For a taller, more impressive pie, use a deep-dish pie plate.
• Don’t overbake! The pie is ready when the center still jiggles slightly. It will firm up perfectly as it cools.
• Embrace the cracks! A few cracks on the surface are a classic sign of a homemade custard pie and add to its rustic charm.
• Swap the crust! Try a whole wheat or oat-based pie crust for a heartier, nuttier flavor profile.
FAQ
Q: Is this blueberry buttermilk pie recipe vegetarian
A: Yes, this recipe is completely vegetarian. It contains dairy and eggs but no meat, poultry, or fish, making it a perfect dessert for a vegetarian diet.
Q: Can I make this blueberry buttermilk pie vegan
A: Making a vegan version of this specific custard pie is challenging due to its reliance on eggs and dairy for its texture. You would need to substitute the pie crust with a vegan version (using vegan butter or oil), use plant-based buttermilk and cream (like coconut cream), and find a suitable egg replacer. The final texture and taste will be significantly different from a traditional custard.
Q: What can I use instead of eggs in this custard pie
A: The eggs are essential for creating the rich, set texture of a classic custard. Unfortunately, there isn’t a simple one-to-one substitute that will replicate it perfectly. Using a cornstarch-based thickener or a commercial vegan egg replacer would result in a different, more pudding-like filling rather than a true custard.
Q: How should I store this vegetarian custard pie
A: Because this pie is made with eggs and dairy, it must be refrigerated. After the pie has cooled completely to room temperature, cover it loosely with plastic wrap or foil and store it in the refrigerator for up to 3 to 4 days.
