Ingredients
- 3 cups fresh rhubarb, chopped into 1/2-inch pieces
- 3 large eggs, room temperature
- 1.5 cups granulated sugar
- 1/4 cup all-purpose flour
- 1/2 cup heavy cream or whole milk
- 1 teaspoon pure vanilla extract
- 1/2 teaspoon ground nutmeg
- 1/4 teaspoon salt
- 1 unbaked 9-inch deep-dish pie crust
- 1 tablespoon unsalted butter, chilled and cubed
Step-by-Step Instructions
- Preheat your oven to 400°F (200°C) and place your unbaked pie crust into a deep-dish pie plate, crimping the edges as desired.
- In a large mixing bowl, whisk together the granulated sugar, all-purpose flour, salt, and ground nutmeg until well combined.
- Add the eggs, heavy cream (or milk), and vanilla extract to the dry ingredients, whisking until the mixture is smooth and the sugar has mostly dissolved.
- Spread the chopped rhubarb evenly across the bottom of the prepared pie crust.
- Slowly pour the custard mixture over the rhubarb, ensuring the pieces are well-coated and the liquid fills the crust evenly.
- Dot the top of the filling with the small cubes of chilled butter.
- Place the pie on a baking sheet to catch any potential drips and bake at 400°F for 15 minutes.
- Reduce the oven temperature to 350°F (175°C) and continue baking for another 35 to 45 minutes, or until the custard is set and the top is lightly golden brown.
- Remove the pie from the oven and place it on a wire rack to cool completely. This step is crucial as the custard will continue to set as it cools.
Expert Tips / Pro Tips
To ensure the best results, always use fresh, firm rhubarb stalks and avoid the leaves, which are toxic. If your rhubarb is particularly juicy, you can toss the chopped pieces with a tablespoon of flour before adding them to the crust to prevent a soggy bottom. For a perfectly set custard, make sure your eggs are at room temperature before whisking. If the edges of your crust begin to brown too quickly, loosely cover them with a pie shield or aluminum foil halfway through the baking process.
Variations & Substitutions
If you prefer a sweeter, fruitier twist, you can substitute one cup of rhubarb with one cup of sliced fresh strawberries to make a Strawberry Rhubarb Custard Pie. For those who enjoy more spice, try adding a half teaspoon of ground ginger or cinnamon to the egg mixture. If you do not have heavy cream on hand, evaporated milk makes an excellent substitute and provides a similarly rich texture. For a gluten-free version, simply use your favorite gluten-free pie crust and a 1-to-1 gluten-free flour blend in the custard filling.
Serving Suggestions
This pie is best served slightly chilled or at room temperature. For a truly indulgent experience, top each slice with a generous dollop of homemade whipped cream or a scoop of premium vanilla bean ice cream. A light dusting of powdered sugar or a few fresh mint leaves can also add an elegant touch to the presentation when serving guests at a brunch or dinner party.
Storage, Freezing & Reheating
Because this pie contains a dairy-based custard, it should be stored in the refrigerator. Cover it loosely with plastic wrap or foil and it will keep well for up to 3 to 4 days. While custard pies are best enjoyed fresh, you can freeze it by wrapping the completely cooled pie tightly in several layers of plastic wrap and foil; it will last for up to 2 months. Thaw in the refrigerator overnight before serving. To reheat, place individual slices in the oven at 300°F for about 10 minutes to take the chill off without overcooking the custard.

FAQ
Can I use frozen rhubarb for this pie?
Yes, you can use frozen rhubarb. Be sure to thaw it completely and drain all excess liquid before adding it to the pie crust to ensure the custard sets properly and the crust doesn’t become soggy.
How do I know when the custard is fully set?
The pie is done when the edges are slightly puffed and golden, and the center has a slight jiggle (like gelatin) but is not liquid. It will firm up significantly as it cools.
Does Rhubarb Custard Pie need to be refrigerated?
Yes, due to the high egg and dairy content in the custard filling, this pie must be kept refrigerated after it has cooled to room temperature.
Can I make this pie in a regular pie dish instead of deep-dish?
This recipe is designed for a deep-dish pan. If using a standard 9-inch pie dish, you may have a little bit of leftover custard filling. Do not overfill the crust, or it may spill over during baking.
