Why We Love This Sourdough Discard Pumpkin Pie

This recipe is especially useful during baking seasons when we have extra sourdough starter to use. Instead of throwing away discard, we can turn it into a flavorful dessert.

The sourdough discard pumpkin pie has several qualities that make it stand out:

• Flaky homemade crust made with cold butter and sourdough discard.
• Creamy pumpkin filling with a smooth custard-like consistency.
• A gentle tangy flavor that balances the sweetness.
• Plenty of classic pumpkin pie spice for a warm fall flavor.
• Cornstarch helps the filling set properly.
• Heavy cream gives the filling a rich, silky texture.
• The recipe works beautifully with either homemade or canned pumpkin puree.
• It is an excellent way to use unfed sourdough discard.

For the best texture, we should allow the finished pie to cool completely before slicing. This gives the custard enough time to finish setting.

Ingredients for Sourdough Discard Pumpkin Pie

For the Flaky Sourdough Crust

• 210g all-purpose flour – about 1 ¾ cups
• 226g unsalted butter, cold and cubed – 1 cup
• 56g sourdough discard – ¼ cup
• 56g cold water – ¼ cup
• 14g cane sugar – 1 tablespoon
• 6g salt – 1 teaspoon

The most important detail when making this crust is keeping the butter cold. Cold butter creates pockets of fat throughout the dough. During baking, those pockets melt and create a flaky, tender crust.

The sourdough discard also contributes moisture and acidity to the dough. We should avoid adding unnecessary extra water because the discard already contains liquid.

For the Velvety Pumpkin Filling

• 425g pumpkin puree – 1 standard 15-ounce can
• 30g sourdough discard – 2 tablespoons
• 100g dark brown sugar, packed
• 70g cane sugar – ⅓ cup
• 3 large eggs
• 226g heavy whipping cream – 1 cup
• 20g cornstarch -approximately 2 tablespoons
• 2 teaspoons pumpkin pie spice
• 1 teaspoon vanilla extract
• 1 pinch salt

Dark brown sugar provides a deeper caramel-like sweetness, while cane sugar keeps the filling from becoming overly heavy. Heavy cream makes the pumpkin custard exceptionally smooth, and cornstarch provides additional structure.

How to Make the Sourdough Discard Pie Crust

• Start by combining the all-purpose flour, cane sugar, and salt in a large mixing bowl.
• Add the cold cubed butter and work it into the flour using a pastry cutter or your fingertips. We want a mixture containing different-sized pieces of butter rather than completely blending the butter into the flour. Some pieces should remain small and pea-sized.
• Add the sourdough discard and gently mix.
• Gradually add the cold water, mixing just until the dough begins to come together. We should not knead the dough like bread dough. Overworking it can develop too much gluten and make the finished crust tough.
• Transfer the dough to a lightly floured surface and gently bring it together into a disk.
• Wrap the dough and refrigerate it for at least 30 to 60 minutes.
• Chilling is important because it allows the butter to firm up again and makes the dough easier to roll.

How to Prepare the Pie Crust

• After chilling, place the dough on a lightly floured work surface and roll it into a circle large enough to fit a standard pie dish.
• Carefully transfer the dough into the pie dish. Gently press it into the bottom and sides without stretching the dough.
• Trim excess dough around the edges and create your preferred decorative crust.
• For an especially crisp bottom crust, refrigerate the shaped crust for another 15 to 20 minutes before baking.
• Line the crust with parchment paper and fill it with pie weights or dried beans.
• Bake the crust until the edges begin to set and turn lightly golden. Remove the parchment and pie weights, then continue baking briefly until the bottom looks dry and lightly colored.
• Allow the crust to cool slightly while we prepare the filling.

How to Make the Pumpkin Filling

• In a large bowl, combine the pumpkin puree, sourdough discard, dark brown sugar, cane sugar, pumpkin pie spice, cornstarch, and salt.
• Whisk until everything is evenly incorporated.
• Add the eggs and vanilla extract and whisk gently.
• Finally, add the heavy whipping cream and mix until the filling becomes smooth.
• We should avoid aggressively whipping the mixture because incorporating a large amount of air can create bubbles on the surface of the baked pie.
• The finished mixture should be smooth, pourable, and evenly colored.

How to Bake Sourdough Discard Pumpkin Pie

• Pour the pumpkin filling into the prepared crust.
• Place the pie on a baking sheet to make transferring it to and from the oven easier and to catch any possible drips.
• Bake the pie at 425°F (220°C) for approximately 15 minutes.
• Then reduce the oven temperature to 350°F (175°C) and continue baking for approximately 40 to 50 minutes, depending on the depth of the pie dish and your oven.
• The edges should look set while the center should still have a gentle wobble.
• We do not want the center to look completely firm when the pie comes out of the oven. Pumpkin custard continues cooking from residual heat, and overbaking can result in cracks or a dry, grainy texture.
• If the crust begins becoming too dark before the filling is finished, loosely cover the edges with aluminum foil or use a pie shield.

How to Tell When Pumpkin Pie Is Done

• One of the easiest ways to check the pie is to gently move the baking dish.
• The outer portion of the filling should look set, while the center should have a slight jiggle rather than a liquid wave.
• For an especially precise check, the center of the filling should reach approximately 175°F (79°C).
• Once baked, remove the pie from the oven and place it on a cooling rack.

Why Add Sourdough Discard to Pumpkin Pie Filling?

Sourdough discard is traditionally associated with bread, pancakes, waffles, and other baked goods, but it can also be incorporated into desserts.

In this sourdough discard pumpkin pie, a small amount of discard adds acidity and another layer of flavor to the sweet pumpkin custard. The amount is deliberately modest, so the pie does not taste strongly sour.

Combined with dark brown sugar, vanilla, pumpkin spice, and cream, the result is a balanced filling with a subtle complexity that complements the buttery crust.

Can We Use Homemade Pumpkin Puree?

Yes. Homemade pumpkin puree can be used, but its water content can vary considerably.

For the most predictable texture, canned pumpkin puree is convenient because its consistency is generally thick and consistent.

If homemade pumpkin puree is particularly watery, we should strain or cook it briefly to remove excess moisture before measuring the 425g needed for the recipe.

Avoid pumpkin pie filling from a can because it may already contain sugar and spices. Plain pumpkin puree gives us complete control over the sweetness and seasoning.

How to Store Sourdough Discard Pumpkin Pie

Once the pie has cooled completely, cover it and refrigerate it.

Because the filling contains eggs and heavy cream, the finished pie should be stored in the refrigerator rather than left at room temperature for an extended period.

Properly refrigerated, the pie is excellent for several days. In fact, preparing it a day ahead can make serving easier because the filling has plenty of time to set.

For serving, we can enjoy the pie cold, at room temperature for a short period, or slightly chilled.

Can We Freeze Pumpkin Pie?

Yes. Pumpkin pie can be frozen once completely cooled.

Wrap the pie tightly in plastic wrap followed by aluminum foil, or place individual slices in airtight freezer-safe containers.

For the best texture, thaw the pie slowly in the refrigerator. Freezing may cause a small change in the custard texture, but the pie will still make an excellent make-ahead dessert.

What to Serve With Sourdough Pumpkin Pie

A slice of pumpkin pie becomes even more special with a simple topping. We can serve it with:

• Whipped cream
• Vanilla ice cream
• A dusting of cinnamon
• A light sprinkle of pumpkin pie spice
• Caramel sauce
• Toasted pecans
• A small drizzle of maple syrup

Freshly whipped cream is particularly delicious because its light texture contrasts with the rich pumpkin custard.
