Classic Homemade Rhubarb Pie
This Classic Homemade Rhubarb Pie features a perfectly tart, golden-bubbling filling tucked inside a flaky, buttery crust. Whether you use fresh or frozen rhubarb, this traditional rhubarb pie is the rustic showstopper your dessert table has been waiting for.
The Tart, Golden Pie That Tastes Like Summer
There is something quietly magical about a traditional rhubarb pie cooling on a kitchen windowsill. The filling bubbles up through the vents like a little ruby-red volcano, the buttery crust turns a deep, burnished gold, and the whole house fills with a sweet-tart perfume that is impossible to resist. This is the rustic rhubarb pie recipe your grandmother made, reimagined with a few modern tips to guarantee a perfect result every single time.
Whether you are working with bright red stalks fresh from the garden or pulling a bag of rhubarb pie using frozen rhubarb from the back of your freezer in the middle of January, this recipe has you covered. It is approachable enough for a first-time pie baker and satisfying enough for a seasoned one.
Using the right tools makes a real difference when it comes to homemade pie. A good pastry cutter keeps the butter cold and your crust properly flaky, and a quality 9-inch glass pie dish lets you see the bottom crust browning so you never end up with a soggy base.
Why This Rhubarb Pie Recipe Works
The secret to any great sweet rhubarb pie comes down to three things: cold butter, enough thickener, and patience.
- Cold butter creates those irresistible flaky layers in the crust. Work quickly and keep everything chilled.
- Cornstarch is the thickener of choice here. It produces a glossy, sliceable filling without dulling the bright tartness of the rhubarb the way flour sometimes can.
- Patience at the end. Letting the pie rest for a full two hours after baking is non-negotiable. The filling needs time to set so you get clean, beautiful slices instead of a soupy mess.
Chef's Tip: If your rhubarb is very thick, split the stalks lengthwise before cutting them into pieces. This ensures the rhubarb cooks evenly and every bite has the same tender texture.
Fresh vs. Frozen Rhubarb
Fresh rhubarb season is fleeting, running roughly from April through June depending on where you live. Outside of that window, a homemade rhubarb pie using frozen rhubarb is just as delicious, as long as you handle it correctly.
Always thaw frozen rhubarb fully and drain it very well. Frozen rhubarb releases a surprising amount of liquid as it thaws, and that extra moisture is the number one reason pies turn out runny. Pat the pieces dry, add a touch more cornstarch, and you are set.
This recipe also works beautifully as a rhubarb slab pie if you want to serve a crowd. Simply press the dough into a rimmed baking sheet, add the filling, top with the second crust, and slice into squares. It is the easiest way to turn this into a party dessert.
Note: Rhubarb leaves are toxic and should never be eaten. Always trim them away completely before cooking.
The Crust: Shortbread-Style Flakiness Without the Fuss
This dough leans into a classic all-butter approach, giving you something closer to a rhubarb tart with a shortbread crust in terms of richness and flavor, but still sturdy enough to hold up to a juicy filling. The key moves are simple:
- Start with ice-cold butter cut into small cubes.
- Add ice water gradually, one tablespoon at a time.
- Rest the dough in the refrigerator for at least one hour before rolling.
This resting period relaxes the gluten and firms the butter back up, making the dough far easier to roll and far flakier after baking.

Classic Homemade Rhubarb Pie
This Classic Homemade Rhubarb Pie features a perfectly tart, golden-bubbling filling tucked inside a flaky, buttery crust. Whether you use fresh or frozen rhubarb, this traditional rhubarb pie is the rustic showstopper your dessert table has been waiting for.
Ingredients
- 2 1/2 cups all-purpose flour, plus more for dusting
- 1/2 tsp granulated sugar, for the crust dough
- 1 tsp salt, for the crust dough
- 1 cup unsalted butter, cold, cut into small cubes
- 6 tbsp ice water, added one tablespoon at a time
- 5 cups fresh or frozen rhubarb, trimmed and cut into 0.5-inch pieces; if frozen, thaw and drain well
- 1 1/4 cups granulated sugar, for the filling; adjust to taste
- 3/8 cups cornstarch, helps thicken the filling
- 1 tsp vanilla extract
- 1 tbsp lemon juice, freshly squeezed
- 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, sugar, and salt. Add the cold cubed butter and use a pastry cutter or your fingertips to work it into the flour until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining.
Add ice water one tablespoon at a time, stirring gently with a fork after each addition, until the dough just comes together and holds when pressed. Divide into two equal discs, wrap each in plastic wrap, and refrigerate for at least 1 hour or overnight.
Prepare the rhubarb filling: In a large bowl, toss the rhubarb pieces with the granulated sugar, cornstarch, vanilla extract, and lemon juice until evenly coated. Let the mixture sit for 10 minutes while you roll out the dough.
Preheat your oven to 400 degrees F (200 degrees C). Place a baking sheet on the lower oven rack to catch any drips.
Roll out one disc of dough on a lightly floured surface into a 12-inch circle. Carefully drape it into a 9-inch pie dish, letting the excess hang over the edges.
Pour the rhubarb filling into the prepared crust, spreading it into an even layer.
Roll out the second disc of dough into another 12-inch circle. Lay it over the filling. Trim any excess dough to about 1 inch beyond the rim, then fold and crimp the edges together to seal. Cut 4 to 5 steam vents in the top crust with a sharp knife.
Brush the top crust with the beaten egg wash and sprinkle generously with coarse sugar.
Place the pie on the preheated baking sheet in the oven. Bake at 400 degrees F for 20 minutes, then reduce the heat to 375 degrees F (190 degrees C) and continue baking for 30 to 35 more minutes, until the crust is deep golden brown and the filling is bubbling through the vents.
Transfer the pie to a wire rack and let it cool for at least 2 hours before slicing. This resting time is essential for the filling to set properly.

Notes
Serving and Storing Your Rhubarb Pie
This pie is stunning served slightly warm with a generous scoop of vanilla ice cream or a cloud of freshly whipped cream. The cold creaminess against the warm tart filling is one of the great dessert combinations.
For a heart-shaped rhubarb pie variation, simply press the dough into a heart-shaped tart pan and decorate the top crust with small heart cutouts using a cookie cutter. It makes an unforgettable Valentine's Day or anniversary dessert.
Leftovers keep beautifully, and honestly, a cold slice of rhubarb pie with a cup of coffee the next morning is one of life's simple pleasures. Store covered at room temperature for up to 2 days, or refrigerate for up to 5 days. The whole pie also freezes well for up to 2 months.
