Ingredients

• 1 unbaked pie shell
• 3 c. chopped rhubarb
• 1 1/4 c. granulated sugar
• 3 eggs beaten
• 1 c. heavy whipping cream
• 3 Tbsp. flour
• 1/2 tsp. salt

How to make Rhubarb Custard Pie

Step 1: Start by preheating your oven to 400°F. Get your unbaked pie shell ready in a pie plate.

Step 2: Evenly distribute the 3 cups of chopped rhubarb across the bottom of the unbaked pie shell.

Step 3: In a separate medium-sized bowl, grab a whisk. Add the granulated sugar, beaten eggs, heavy whipping cream, flour, and salt. Whisk everything together vigorously until the mixture is completely smooth and no lumps of flour remain.

Step 4: Carefully pour the smooth custard mixture over the rhubarb in the pie shell, making sure it covers all the pieces.

Step 5: Place the pie in the preheated oven and bake for 10 minutes at 400°F. Then, without opening the oven door, reduce the temperature to 350°F and continue to bake for an additional 40 minutes.

Step 6: The pie is done when the custard is mostly set. The very center might still have a slight jiggle to it, which is perfectly fine. It will firm up as it cools. Let the pie cool completely on a wire rack to room temperature before slicing and serving. Store any leftovers in the refrigerator.

How to serve Rhubarb Custard Pie

This pie is at its absolute best when served completely chilled. The cold temperature enhances the firm, creamy texture of the custard and makes the tartness of the rhubarb pop. A slice on its own is pure perfection, but it’s also fantastic with a dollop of freshly whipped cream or a simple scoop of vanilla bean ice cream to complement the flavors.

How to store Rhubarb Custard Pie

Because this is an egg-based custard pie, it must be stored in the refrigerator. Once the pie has cooled completely to room temperature, cover it loosely with plastic wrap or foil. It will keep well in the fridge for up to 3-4 days. The crust may soften slightly over time, but the flavor will remain delicious.

Tips to make

• Rhubarb Prep: For the best results, use fresh, firm rhubarb stalks. There’s no need to peel them; the skin adds a beautiful rosy color to the pie. If you’re using frozen rhubarb, be sure to thaw it completely and drain off any excess liquid before adding it to the pie crust to avoid a watery filling.
• The Jiggle Test: Knowing when a custard pie is done can be tricky. The edges should be set, but the center (about a 2-inch circle) should still jiggle slightly, like gelatin. If you overbake it, the custard can become rubbery or crack.
• Cooling is Crucial: Do not skip the cooling process! The pie needs to cool completely to allow the custard to set fully. Slicing into a warm pie will result in a runny mess. Be patient; it’s worth the wait.

FAQs About Rhubarb Custard Pie

What does rhubarb taste like?

Rhubarb has a very tart, tangy flavor that is often compared to green apples or cranberries. On its own, it’s quite sour, which is why it’s almost always cooked with sugar in desserts like pies, crisps, and jams. Its texture, when cooked, becomes soft and tender.

Can I use a store-bought pie crust?

Absolutely! A store-bought refrigerated or frozen pie crust works perfectly for this recipe and is a great time-saver. Simply place it in your pie dish and use it as directed; no pre-baking is required.

Why is my custard pie runny?

There are two common reasons for a runny custard pie. The first is that it may have been slightly underbaked. The second, and more common reason, is that it wasn’t allowed to cool completely. The custard continues to set and firm up as it cools, so cutting into it while it’s still warm will prevent it from holding its shape.
