• ¼ cup all-purpose flour – Helps thicken the custard and gives it a lovely texture.
• ½ teaspoon fine-grain salt – Enhances the flavors and balances the sweetness.

For the Crust

How to Make Rhubarb Custard Pie
Combine the sliced rhubarb and ¾ cup granulated sugar in a medium bowl. Let this mixture rest for about 30-45 minutes, allowing the rhubarb to release its juices. Pour off excess liquid, saving it if you wish.
Preheat your oven to 400°F (200°C). Meanwhile, place the deep-dish pie shell on a baking sheet to catch any drips during baking.
Mix the remaining 1 ¼ cups granulated sugar, flour, and salt in a large bowl. Use a pastry cutter or fork to incorporate the cold butter until it’s nicely broken up and mixed throughout. Stir in the beaten eggs until smooth, then gently fold in the drained rhubarb.
Pour the rhubarb mixture into the unbaked pie shell. Transfer the baking sheet to the oven, and bake for 15 minutes to set the crust.
Reduce the oven temperature to 325°F (160°C) without opening the oven door. Continue to bake for an additional 45-60 minutes, until the pie only has a slight wobble in the center.
Cool the pie by transferring the plate to a cooling rack. Let it reach room temperature, then cover it with foil and refrigerate before serving to enhance the flavors.
Optional: Serve with a dollop of homemade whipped cream for an extra touch of indulgence!

Tips for the Best Rhubarb Custard Pie
Use Fresh Rhubarb: Always opt for fresh rhubarb rather than frozen for better texture and flavor in your custard pie.
Avoid Over-Sweetening: Be cautious with the sugar; the tartness of rhubarb should shine through. Taste the rhubarb mixture before adding all the sugar.
Perfect Crust Technique: Ensure your pie crust is frozen before adding the filling to prevent sogginess; this maintains the perfect flaky texture.
Monitor Baking Time: Keep an eye on the pie as it bakes; an overly cooked filling will lose its custardy charm, while underbaking can lead to a runny texture.
Chill Before Serving: Let your rhubarb custard pie cool completely, then refrigerate it. This allows flavors to meld beautifully and enhances the overall experience.
Serve with Whipped Cream: A topping of homemade whipped cream or a scoop of vanilla ice cream adds a delightful contrast to the tartness of the pie, making it irresistible!
How to Store and Freeze Rhubarb Custard Pie
Room Temperature: If serving the pie the same day, you can leave it at room temperature for up to 2 hours. After that, cover it with foil to keep it fresh.
Fridge: Store the pie in the refrigerator for up to 3 days. Use an airtight container or cover it tightly with plastic wrap or foil to prevent it from drying out.
Freezer: If you need to freeze your rhubarb custard pie, wrap it tightly in plastic wrap and then aluminum foil. It can last in the freezer for up to 2 months.
Reheating: To reheat, place slices in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until warmed through. This will help restore that lovely creamy texture!

Rhubarb Custard Pie Recipe FAQs
What type of rhubarb should I use for this pie?
Absolutely! For the best taste and texture, use fresh rhubarb with firm stalks that are vibrant in color, preferably a deep rosy hue. Avoid rhubarb that appears limp or has dark spots, as this may indicate it’s past its prime.
How should I store leftover rhubarb custard pie?
Very simply! If you plan to eat the pie within 3 days, store it in the fridge, covering it tightly with plastic wrap or foil to keep it fresh. For longer storage, consider freezing!

What should I do if my pie filling looks too runny after baking?
If the filling is runny, it’s likely due to not baking long enough or not draining the rhubarb properly. Make sure to bake the pie until it has only a slight wobble in the center. Testing with a knife can help; if it comes out coated with a thick custard, it’s perfect!
