Southern 3-Ingredient Water Pie

Servings: 8

If you have never heard of Water Pie, you are in for a delightful surprise. This Southern 3-Ingredient Water Pie is a true Depression-era classic, born from a time when pantry staples were scarce, and clever cooks had to make something out of almost nothing. Yet, despite being made with just sugar, water, and a pie crust, it bakes into a beautifully golden, creamy, and custard-like dessert that is deeply comforting and surprisingly delicious.

It is a testament to the fact that good food doesn’t have to be complicated or expensive. It is the perfect easy dessert for a weeknight treat or a nostalgic addition to a holiday table.

Why This Recipe Works

This recipe relies on the magic of baking science. As the sugar and water mixture bakes, it thickens and sets into a soft, custard-like filling. The high initial heat (400°F) helps the crust start to set and the filling begin to thicken, while the lower heat (350°F) gently bakes the center through without burning the crust. The result is a pie with a flaky, golden crust and a sweet, creamy, and slightly jiggly center.

Ingredients

• 1 (9-inch) unbaked pie crust, fitted in a glass pie plate
• 1 1/2 cups granulated sugar
• 2 cups room-temperature water

Directions

1. Preheat your oven to 400°F (200°C). Place a rack in the middle of the oven. Set a glass 9-inch pie plate with the unbaked pie crust on a baking sheet to catch any drips and make it easier to move.
2. If the crust is very soft from sitting out, chill the pie shell in the refrigerator for about 10 minutes while the oven heats. This helps the crust stay flaky and hold its shape.
3. In a medium bowl or large liquid measuring cup, whisk together the granulated sugar and room-temperature water until the sugar is mostly dissolved. The mixture will look thin; that’s exactly what you want.
4. Pour the sugar-water mixture gently into the unbaked pie crust. Fill carefully so you don’t splash over the edges. The liquid level should come close to the top of the crust but not overflow.
5. Carefully slide the baking sheet with the pie into the preheated oven. Bake at 400°F (200°C) for 20 minutes to help the crust start to set and the filling begin to thicken around the edges.
6. After 20 minutes, reduce the oven temperature to 350°F (175°C) without opening the door if possible, and continue baking for another 30–40 minutes. The edges of the crust should be deep golden and the filling should look mostly set with a slight wobble in the center, similar to a soft custard.
7. If the crust edges are browning too quickly before the filling is set, loosely cover just the rim with strips of foil or a pie shield and continue baking until done.
8. Remove the pie from the oven and place the glass pie plate on a cooling rack. The filling will appear a bit jiggly at first but will firm up as it cools. Cool at least 2 hours at room temperature before slicing so the center can finish setting into a creamy, custard-like texture.
9. Once cooled and set, slice the pie into 8 wedges using a sharp knife. For the cleanest slices, wipe the knife between cuts. Serve at room temperature or slightly warmed.

Tips for the Best Results

Use room-temperature water. Room-temperature water helps the sugar dissolve more easily and ensures the filling bakes evenly.

Chill the crust if needed. If your pie crust is soft or sticky, chilling it for 10 minutes before filling helps it hold its shape in the oven.

Watch the crust. If the edges of the crust start to brown too quickly, cover them with foil or a pie shield to prevent burning.

Let it cool completely. The 2-hour cooling time is essential. The filling will be very jiggly straight out of the oven and needs time to set into a creamy, sliceable texture.

Don’t skip the baking sheet. Placing the pie plate on a baking sheet catches any drips and makes it much easier to move the pie in and out of the oven.

Storage and Serving

Store leftover pie covered in the refrigerator for up to 3 days. Serve it chilled or at room temperature. It is delicious on its own, but it also pairs beautifully with a dollop of whipped cream or a sprinkle of cinnamon.

Simple, sweet, and completely nostalgic, this Southern 3-Ingredient Water Pie is a fantastic recipe to keep in your rotation for easy, old-fashioned desserts.
