How can I tell if my rhubarb custard pie is fully cooked?

You can tell your rhubarb custard pie is fully cooked when the custard around the edges appears set, and the center has only a slight wobble when gently shaken. An internal temperature of 175-180°F (80-82°C) is ideal, if you're using a thermometer. The crust should also be golden brown and crisp.

Can I use frozen rhubarb for this rhubarb custard pie recipe?

Yes, you can use frozen rhubarb. There's no need to thaw it first. Just add it directly to the sugar and flour mixture. Be aware that frozen rhubarb may release more moisture, so you might consider adding an extra tablespoon of flour or cornstarch to the filling to help absorb any additional liquid and prevent a watery pie.

Why did my rhubarb custard pie crack on top?

Cracking on top of your rhubarb custard pie can happen if the pie bakes too quickly or at too high a temperature, causing the outer edges to set before the center finishes baking and expands. Cooling the pie too quickly can also cause cracks. While it doesn't affect the taste, you can mask cracks with whipped cream or a dusting of powdered sugar.

Can I make this rhubarb custard pie recipe ahead of time?

Absolutely! Rhubarb custard pie is an excellent make-ahead dessert. In fact, it tastes even better the next day after the flavors have had a chance to meld and the custard has fully set in the refrigerator. Just follow the storage instructions mentioned above to keep it fresh until you're ready to serve.

The Best Rhubarb Custard Pie Recipe: Sweet & Tart Spring

Ingredients

Scale

1 ½ cups all-purpose flour (for crust)
½ teaspoon salt (for crust)
½ cup (1 stick) cold unsalted butter, cut into cubes
¼ cup ice water
4 cups chopped fresh rhubarb (about 1 pound)
1 cup granulated sugar (divided)
¼ cup all-purpose flour (for filling)
2 large eggs
¾ cup heavy cream
1 teaspoon vanilla extract
Pinch of ground nutmeg

Instructions

Step 1: Prepare Pie Crust – In a large bowl, whisk together 1 ½ cups flour and ½ teaspoon salt. Cut in the cold butter with a pastry blender or your fingertips until the mixture resembles coarse crumbs. Gradually add ice water, mixing until the dough just comes together. Form into a disk, wrap, and chill for 30 minutes.
Step 2: Roll and Place Crust – On a lightly floured surface, roll out the chilled dough into a 12-inch circle. Carefully transfer the dough to a 9-inch pie plate and trim/crimp the edges as desired.
Step 3: Prepare Rhubarb – In a separate bowl, toss the chopped rhubarb with ½ cup of the granulated sugar and 1 tablespoon of the ¼ cup all-purpose flour.
Step 4: Make Custard Filling – In another bowl, whisk together the remaining ½ cup granulated sugar, the remaining 3 tablespoons of ¼ cup all-purpose flour, eggs, heavy cream, vanilla extract, and ground nutmeg until smooth.
Step 5: Assemble Pie – Arrange the rhubarb mixture evenly in the prepared pie crust. Pour the custard mixture over the rhubarb.
Step 6: Bake Pie – Bake in a preheated oven at 400°F (200°C) for 15 minutes. Reduce the oven temperature to 350°F (175°C) and continue baking for another 40-50 minutes, or until the custard is set and the crust is golden brown. A knife inserted near the center should come out clean.
Step 7: Cool and Serve – Let the pie cool completely on a wire rack for at least 2-3 hours before slicing and serving. This allows the custard to fully set.
