This fabulous rhubarb custard pie is adapted from a vintage recipe leaflet from Washington State Rhubarb Growers. It's such a simple recipe, and if you use a frozen or ready-made pie crust, it takes no more than 15 minutes to prepare. A small amount of nutmeg adds flavor to the pie but you can use ground cinnamon instead.

The all-butter pie crust is easy to make using a food processor, but you can cut prep time by about half if you make the pie with a frozen pie crust, homemade pastry, or refrigerated pie pastry sheets. A rhubarb pie with a custard filling will set up nicely, and you won't have to worry about fruit juices running—a common scenario with pies filled exclusively with fruit.
Serve this pie at your next cookout or take it along to a potluck dinner. This is a fantastic way to use fresh rhubarb, and your family and friends will love it. It's no wonder rhubarb was once called "the pie plant."
Do you have to peel rhubarb for pie?
Fresh and peak-season rhubarb does not need to be peeled before baking with it. Some people like to peel rhubarb when it's a bit further along in the season because the exterior can be a little tough.
Tip for Making Rhubarb Custard Pie Recipe
You can use frozen rhubarb for this custard pie. Just make sure you defrost the fruit and pat it completely dry.
"This super-easy pie is a classic and a great way to use up tart rhubarb. You can adjust the sugar a bit depending on exactly how sour your fruit is. I'll try adding a little vanilla extract next time." —Laurel Randolph
