What Is Rhubarb Custard Pie?
Rhubarb custard pie is a traditional dessert made with fresh rhubarb and a sweet custard filling baked inside a pie shell. The custard is typically made with eggs, sugar, and cream, creating a smooth, rich texture once baked.
The tartness of the rhubarb contrasts beautifully with the creamy custard, making each bite both refreshing and indulgent.
Some variations include crumb toppings, strawberries, or even sour cream in the custard mixture, but the classic version keeps things simple.
Choosing the Best Rhubarb
When selecting rhubarb for baking, look for firm, crisp stalks with vibrant red or pink coloring. The color doesn’t necessarily indicate sweetness, but it does give the pie a beautiful appearance.
Avoid stalks that appear limp or bruised.
Fresh rhubarb is most abundant in spring and early summer, making this pie an ideal seasonal dessert.
Keep in mind that rhubarb leaves are poisonous and should never be eaten. Only the stalks are used in cooking.

How to Make Rhubarb Custard Pie
Making this pie is easier than you might think.
Start by preparing or rolling out your pie crust and placing it into a pie dish. Some bakers prefer to blind bake the crust briefly to prevent sogginess.
Next, chop fresh rhubarb into small pieces and spread them evenly over the crust.
In a mixing bowl, whisk together eggs, sugar, cream, vanilla, and a small amount of flour or cornstarch. This mixture forms the custard.
Pour the custard mixture over the rhubarb, ensuring the fruit is evenly coated.
Bake the pie until the custard is set and the crust turns golden brown.
Allow the pie to cool before slicing.
