The Only Rhubarb Pie Recipe You Will Ever Need
There is something deeply comforting about a traditional rhubarb pie cooling on the kitchen counter. That ruby-red filling, the shattering buttery crust, the way the whole house fills with a sweet and tangy fragrance that is equal parts nostalgic and exciting. Whether you grew up eating rhubarb pies at your grandmother's table or you are discovering this classic for the very first time, this recipe delivers everything you want: a gorgeously flaky homemade crust, a luscious filling that is perfectly balanced between tart and sweet, and a showstopping finish that looks like it came straight from a farmhouse bakery.
This is not just any rhubarb pie recipe. It is the kind of rustic rhubarb pie recipe that earns recipe requests every single time you make it.
Why This Recipe Works
Rhubarb has a reputation for being difficult, but it is actually one of the most forgiving fruits you can bake with, especially when you understand a few key principles:
- Sugar balance is everything. Rhubarb is intensely tart on its own. Using 1.25 cups of sugar might sound like a lot, but it transforms the stalks into a silky, jammy filling with a bright, complex flavor rather than a mouth-puckering one.
- Cornstarch is the thickener you want. Unlike flour, cornstarch creates a glossy, clear filling that lets that beautiful deep-red color really shine through.
- Cold butter makes the crust. This is the non-negotiable rule of flaky pastry. Warm butter melts into the flour too early and you lose those distinct, shattering layers.
- Patience with cooling is essential. Cutting into a warm pie is the number one reason for a runny filling. Give it at least two to three hours and you will be rewarded with clean, beautiful slices.
Chef's Tip: If you want a deeper pink filling, choose the reddest rhubarb stalks you can find. Green rhubarb is perfectly fine in flavor but will produce a more muted, greenish filling. Both taste wonderful.
Fresh vs. Frozen Rhubarb
One of the most common questions about making rhubarb pies is whether frozen rhubarb is acceptable. The answer is a resounding yes. Rhubarb pie using frozen rhubarb is just as delicious as one made with fresh stalks, as long as you thaw and drain the rhubarb thoroughly before mixing your filling. Excess moisture is the only real enemy here, and a quick drain solves it completely.
Fresh rhubarb is at its peak from late spring through early summer, but frozen rhubarb means you can bake this pie in the middle of January and still nail it every time.
Having the right tools really does make a difference when it comes to pastry. A good pastry cutter, a reliable 9-inch pie dish with deep sides, and a heavy rolling pin are the three investments that will transform your pie baking for years to come.
Tips for a Beautiful Lattice or Solid Crust Top
For a classic lattice top, roll out your second dough disc and cut it into strips about an inch wide using a sharp knife or a fluted pastry wheel. Weave the strips over and under each other directly on top of the filling, then trim and crimp the edges neatly. A lattice top not only looks stunning but also allows steam to escape more evenly, which helps the filling set beautifully.
If you prefer a solid top crust, cut four or five small vents in the center with a sharp knife before baking. Want something extra special? Use a small cookie cutter to punch decorative shapes, like hearts, into the top crust for a charming heart-shaped rhubarb pie effect that is perfect for a celebration.
Either way, that egg wash and coarse sugar finish is non-negotiable. It gives the crust a gorgeous golden sheen and a delicate crunch that makes every bite even better.

Classic Homemade Rhubarb Pie
This rustic homemade rhubarb pie features a flaky, buttery shortbread crust wrapped around a perfectly sweetened, vibrant rhubarb filling that is tart, tender, and absolutely irresistible.
Ingredients
- 2 1/2 cups all-purpose flour, plus extra for dusting
- 1 tbsp granulated sugar, for the crust
- 1/2 tsp salt
- 1 cup unsalted butter, cold, cubed
- 6 tbsp ice water, added gradually
- 5 cups fresh or frozen rhubarb, cut into 0.5-inch pieces, thawed and drained if frozen
- 1 1/4 cups granulated sugar, for the filling, adjust to taste
- 1/4 cup cornstarch
- 1 tbsp lemon juice, freshly squeezed
- 1 tsp vanilla extract
- 1 large egg, beaten, for egg wash
- 1 tbsp coarse sugar, for sprinkling on top crust
Instruction
Make the pie dough: In a large bowl, whisk together the flour, 1 tablespoon granulated sugar, and salt. Add the cold cubed butter and use a pastry cutter or your fingertips to work it in until the mixture resembles coarse pea-sized crumbles.
Drizzle in the ice water one tablespoon at a time, mixing gently with a fork after each addition, until the dough just comes together and holds when pinched. Do not overwork it.
Divide the dough into two equal discs, wrap each in plastic wrap, and refrigerate for at least 1 hour or up to 2 days.
Preheat your oven to 400 degrees F (200 degrees C). Place a baking sheet on the lower rack to catch any drips.
Make the filling: In a large bowl, toss together the rhubarb pieces, 1.25 cups granulated sugar, cornstarch, lemon juice, and vanilla extract until the rhubarb is evenly coated. Let it sit for 10 minutes.
On a lightly floured surface, roll out one disc of dough into a 12-inch circle. Carefully transfer it to a 9-inch pie dish, pressing it gently into the bottom and sides. Trim the overhang to about 1 inch.
Pour the rhubarb filling into the prepared crust, spreading it evenly.
Roll out the second disc of dough into a 12-inch circle. Lay it over the filling, or cut it into strips for a classic lattice top. Trim, fold, and crimp the edges to seal.
If using a solid top crust, cut 4 to 5 small slits in the center to allow steam to escape.
Brush the top crust with the beaten egg wash and sprinkle generously with coarse sugar.
Bake at 400 degrees F for 20 minutes, then reduce the oven temperature to 375 degrees F (190 degrees C) and continue baking for 30 to 35 minutes more, until the crust is deep golden brown and the filling is visibly bubbling through the vents.
Transfer the pie to a wire rack and allow it to cool for at least 2 to 3 hours before slicing. This resting time is essential for the filling to set properly.
Equipment
- 9-inch pie dish
- Large mixing bowl
- Pastry cutter or food processor

Notes
Serving and Storing Your Rhubarb Pie
This pie is genuinely at its best served at room temperature, which is another reason the cooling window matters so much. Pair a generous slice with a scoop of good vanilla ice cream or a dollop of lightly sweetened whipped cream to balance the tartness of the filling.
Leftovers keep loosely covered at room temperature for two days, or refrigerated for up to four days. To revive a slice the next day, pop it in a 325 degree F oven for ten minutes and the crust will come back to life beautifully.
However you slice it, literally and figuratively, this sweet rhubarb pie is the kind of bake that turns a simple afternoon into a memory worth keeping.
