What You’ll Need (Ingredient Highlights)
Rhubarb gives this pie its bright, tangy flavor and soft baked texture.

Butter adds richness to both the filling and the crumble.
Cinnamon and nutmeg give the topping a warm, cozy finish.
Pro Tips Before You Start
Brush the crust with egg white before pre-baking to help create a moisture barrier.
Keep the crumble butter cold so the topping bakes up crisp and crumbly.
Do not skip the cooling time after baking, or the filling may be too loose when sliced.
Place a baking sheet under the pie while baking to catch any drips.
How to Make Rhubarb Crumble Pie
Step 1 – Prepare the crust
Preheat the oven to 400°F and place the oven rack in the lower third. Unroll the pie crust into a 9-inch pie dish, brush the inside lightly with egg white, and pre-bake for 5 minutes.
Step 2 – Make the filling
In a medium bowl, whisk together the egg, flour, sugar, and vanilla until smooth. Stir in the melted butter, then gently fold in the rhubarb pieces.
Step 3 – Make the crumble topping
In a separate bowl, combine flour, sugar, salt, cinnamon, and nutmeg. Cut in the chilled butter with a fork or your fingertips until the mixture looks like coarse crumbs.
Step 4 – Assemble the pie
Pour the rhubarb filling into the pre-baked crust and spread it evenly. Sprinkle the crumble topping evenly over the filling.
Step 5 – Bake the pie
Bake at 400°F for 10 minutes. Lower the oven temperature to 375°F and continue baking for 40 to 45 minutes, until the filling bubbles and the top is golden brown.
Step 6 – Cool before slicing
Let the pie cool on a wire rack for at least 30 minutes before slicing. This helps the filling set properly.
What to Serve Them With
Serve this pie slightly warm with a scoop of vanilla ice cream.
A dollop of whipped cream also pairs beautifully with the tart rhubarb filling.
For a simple finish, enjoy it with hot tea or coffee.
Variations / Substitutions
Swap part of the rhubarb with strawberries for a sweeter fruit filling.
Use brown sugar in the crumble for a deeper caramel-like flavor.
Add a little orange zest to the filling for a brighter citrus note.
You can use a homemade pie crust instead of refrigerated crust if preferred.
Storage & Leftovers
Store leftover pie covered in the refrigerator for up to 4 days.
For the best texture, let slices come to room temperature or warm them slightly before serving.
You can also freeze the baked pie for up to 2 months. Thaw overnight in the refrigerator before serving.
FAQs
Can I make this pie ahead of time?
Yes, you can bake it a day ahead and store it in the refrigerator until ready to serve.
How do I keep the crust from getting soggy?
Brushing it with egg white and pre-baking it briefly helps protect the crust from the juicy filling.
Can I use frozen rhubarb?
Yes, but thaw and drain it well first so the filling does not become too watery.
How do I know when the pie is done?
The filling should be bubbling around the edges and the crumble topping should be golden brown.
Can I freeze this pie?

What if I do not have nutmeg?

Absolutely. A homemade crust works just as well in this recipe.
Do I need any special equipment?
No, just basic baking tools like mixing bowls, a pie dish, and a whisk or fork.
