Classic Rhubarb Strawberry Pie
This classic rhubarb strawberry pie delivers the perfect balance of tart and sweet, wrapped in a flaky golden crust. A beloved homestyle dessert that tastes like summer in every slice.
The Best Strawberry Rhubarb Pie You Will Ever Bake
There is something deeply nostalgic about a bubbling rhubarb strawberry pie cooling on the counter. That vivid ruby filling, the sweet fragrance drifting through the kitchen, the promise of that first perfect slice. This is the kind of pie that people ask for by name at every summer gathering, the kind that gets passed down through generations scribbled on an index card.
This classic rhubarb strawberry pie hits every note you want. The rhubarb brings a bright, tangy pucker. The strawberries soften everything with natural sweetness. Together they create a filling that is bold, jammy, and completely irresistible. Whether you call it a rustic rhubarb strawberry pie or a polished lattice showstopper, this recipe delivers every single time.
Why This Recipe Works
A great strawberry rhubarb pie comes down to three things: the right fruit ratio, the right thickener, and patience.
Most rhubarb strawberry pie recipes lean too sweet or end up with a watery filling that soaks right through the crust. This recipe solves both problems. We use quick-cooking tapioca rather than flour or cornstarch because tapioca produces a cleaner, jewel-like gel that holds its shape beautifully when you cut a slice. It is the same technique you will find in old-fashioned diner pies, and it genuinely makes a difference.
We also let the filling macerate for 15 minutes before it goes into the crust. That short rest allows the tapioca granules to start absorbing juice before the heat of the oven does the rest of the work.
The right tools and quality ingredients matter just as much as technique here. A good heavy pie dish, a reliable rolling pin, and fresh tapioca from a trusted brand can take this pie from good to genuinely spectacular.
Choosing Your Rhubarb and Strawberries
For the best strawberry rhubarb pie, fresh fruit is always the first choice. Look for firm, brightly colored rhubarb stalks without any limpness or browning at the cut ends. Thinner stalks tend to be more tender and less fibrous than thick ones.
For the strawberries, go for ripe but not overripe berries. Very soft strawberries will break down completely in the oven, losing their shape. You want berries that are deeply red all the way through, sweet-smelling, and still holding their form when halved.
Chef's Tip: If your rhubarb tastes extremely tart on its own, bump the sugar up by 2 tablespoons. Taste a small piece raw before you start. Every batch of rhubarb is a little different.
If you are working with frozen fruit for this rhubarb strawberry pie recipe, no need to thaw. Just mix the frozen pieces directly with the sugar and tapioca, and add an extra tablespoon of tapioca to compensate for the additional liquid frozen fruit releases.
Tips for a Flaky, Golden Crust
A beautiful crust makes a rustic rhubarb strawberry pie look like it came straight from a bakery window. Here are a few things that genuinely help:
- Keep everything cold. Cold butter, cold water, cold hands if possible.
- Do not overwork the dough. Mix just until it comes together. Visible butter streaks are your friend.
- Chill the assembled pie for 15 minutes before baking if you have time. This firms up the fat and helps the crust hold its shape.
- Bake hot first, then lower the temperature. Starting at 425 degrees F sets the crust quickly before the filling has a chance to make it soggy.
A lattice top is a beautiful option for this pie because it lets steam escape evenly and shows off that gorgeous ruby filling underneath. But a solid top crust with cut vents works just as well, especially for a weeknight bake.

Classic Rhubarb Strawberry Pie
This classic rhubarb strawberry pie delivers the perfect balance of tart and sweet, wrapped in a flaky golden crust. A beloved homestyle dessert that tastes like summer in every slice.
Ingredients
- 3 cups fresh rhubarb stalks, trimmed and cut into 0.5-inch pieces
- 2 cups fresh strawberries, hulled and halved
- 1 cup granulated sugar, adjust to taste depending on tartness of rhubarb
- 3 tbsp quick-cooking tapioca, or substitute cornstarch for a smoother filling
- 1 tbsp lemon juice, freshly squeezed
- 1 tsp lemon zest, optional but highly recommended
- 1/2 tsp vanilla extract
- 1/4 tsp salt
- 2 tbsp unsalted butter, cut into small cubes, cold
- 1 double pie crust, store-bought or homemade, enough for a 9-inch pie with a top crust
- 1 large egg, beaten, for egg wash
- 1 tbsp coarse sugar, for sprinkling on top crust
Instruction
Preheat your oven to 425 degrees F (220 degrees C) and position a rack in the lower third of the oven. Place a rimmed baking sheet on the rack below to catch any drips.
In a large bowl, combine the rhubarb pieces and halved strawberries. Add the granulated sugar, tapioca, lemon juice, lemon zest, vanilla extract, and salt. Toss gently until everything is evenly coated. Let the mixture sit for 15 minutes so the tapioca can begin absorbing the juices.
Roll out one disc of pie dough on a lightly floured surface to about 12 inches in diameter. Carefully transfer it to a 9-inch pie dish, pressing it gently into the bottom and sides. Trim any overhang to about 0.5 inches beyond the rim.
Pour the fruit filling into the prepared crust, spreading it evenly. Scatter the cold butter cubes over the top of the filling.
Roll out the second disc of dough to 12 inches in diameter. Lay it over the filling, trim to match the bottom crust overhang, then fold and crimp the edges together to seal. Alternatively, cut the dough into strips and weave a lattice top.
Cut several small slits in the top crust to allow steam to escape, or leave the lattice as your vent. Brush the entire top crust with the beaten egg wash and sprinkle with coarse sugar.
Bake at 425 degrees F for 20 minutes, then reduce the temperature to 375 degrees F (190 degrees C) and continue baking for 30 to 35 minutes, until the crust is deep golden brown and the filling is bubbling through the vents.
Remove the pie from the oven and let it cool on a wire rack for at least 2 hours before slicing. This resting time is essential for the filling to set properly.
Equipment
- 9-inch pie dish

Notes
Serving and Storing Your Pie
Patience is genuinely the hardest part of making the best strawberry rhubarb pie. After all that work, waiting 2 full hours before slicing feels almost cruel. But that cooling time is what allows the tapioca to fully set the filling. Cut too soon and you will have a delicious but very runny strawberry rhubarb pie slice.
Serve it at room temperature or barely warm, with a generous scoop of vanilla ice cream or a cloud of fresh whipped cream. The contrast of cold cream against the warm, jammy filling is one of life's simple pleasures.
Leftovers keep well loosely covered at room temperature for up to 2 days, or refrigerated for up to 5 days. Reheat slices in a low oven rather than the microwave to keep that crust crisp.
This pie also freezes beautifully. Wrap the fully cooled pie tightly in two layers of plastic wrap followed by foil and freeze for up to 3 months. Thaw overnight in the refrigerator and warm gently before serving.
