Strawberry Rhubarb Pie

I first made this strawberry rhubarb pie on a sun-drenched weekend when both fruits were at their peak, and it instantly became my go-to for potlucks and lazy Sunday desserts. Bright, tart rhubarb pairs with sweet strawberries under a buttery crust and a crunchy oat-brown-sugar topping — a perfect balance of sweet and tangy that feels both nostalgic and fresh. If you love fruit-forward pies but want something with a little extra complexity, this is it. For a more rustic take with a fruit-forward crumble top, try the strawberry rhubarb crumble pie for another variation I enjoy.

What makes this recipe special

This pie shines because it layers contrasting textures and flavors: juicy, slightly tart filling, a tender bottom crust, and a crisp oat-based streusel. It’s simple enough for a weeknight bake but pretty enough for holidays or a summer potluck. The crumble topping gives it extra crunch without the fuss of weaving a lattice.

“The first bite is bright and tart, the second is pure comfort—like summer wrapped in a golden crust.” — a quick review from a friend who requested it again the next week

Why you’d reach for this recipe: it’s forgiving (no perfect pastry skills required if you use a store-bought crust), flexible with sweetness, and ideal when strawberries and rhubarb are in season.

How this recipe comes together

Step-by-step overview:

Prep the fruit: slice strawberries and chop rhubarb, then toss with sugar, flour, lemon, and vanilla to macerate.
Make the oat streusel: mix brown sugar, oats, flour, cinnamon, and butter until crumbly.
Assemble: fit the pie crust into the pan, add the filling, and sprinkle the crumble evenly on top.
Bake: until the filling bubbles and the topping is golden. Cool to set before slicing.

Expect about 15–20 minutes active prep and 45–55 minutes baking time. Total time ~1 hour 15 minutes including cooling.

Gather these items

Ingredient list (serves about 6–8):

1.5 cups strawberries, sliced (Use fresh strawberries for the best flavor; if frozen, thaw and drain.)
1.5 cups rhubarb, chopped (Fresh rhubarb is recommended; if frozen, thaw and pat dry.)
1 cup granulated sugar (Adjust depending on the fruit’s sweetness.)
0.25 cups all-purpose flour (helps thicken the filling; cornstarch is a good 1:1 substitute if you prefer a clearer filling)
0.5 teaspoon vanilla extract
1 tablespoon lemon juice (brightens the flavors)
1 pre-made pie crust (Feel free to use homemade if preferred; blind-bake a bit for a crispier bottom)
0.5 cup brown sugar (for the streusel)
0.5 cup rolled oats
0.5 cup all-purpose flour (for the streusel)
0.25 cup butter, softened (cold butter yields flakier crumbs; softened easier to mix)
0.5 teaspoon cinnamon

Notes: If you want a gluten-free pie, swap the crust and streusel flour for a 1:1 gluten-free flour blend. Reduce sugar slightly if your strawberries are very ripe.

Step-by-step instructions

Preparation

Preheat the oven to 375°F (190°C). Place a rimmed baking sheet in the oven (you’ll bake the pie on it to catch any drips).
In a large bowl, gently combine strawberries, rhubarb, 1 cup sugar, 0.25 cup flour, vanilla, and lemon juice. Let sit 10 minutes to macerate — this draws out juices and helps meld flavors.

Assembly
3. Fit the pre-made pie crust into a 9-inch pie pan. Trim and flute the edges as desired.
4. Pour the fruit mixture into the crust, spreading evenly.
5. For the streusel: mix brown sugar, oats, 0.5 cup flour, cinnamon, and softened butter with a fork or pastry cutter until crumbly. Sprinkle evenly over the filling.

Baking
6. Place the pie on the preheated rimmed baking sheet and bake at 375°F for 45–55 minutes, until the filling is bubbling through the streusel and the topping is golden brown. If the crust or topping browns too quickly, tent loosely with foil after 30 minutes.
7. Remove from oven and cool on a rack for at least 2 hours so the filling sets; slice once mostly cooled.

Best ways to enjoy it

Serve warm or at room temperature. A scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream pairs beautifully with the tartness of rhubarb. For a brunch table, slice and serve with mascarpone and a drizzle of honey. If you want to make it picnic-ready, chill completely and cut into wedges; cold slices hold together better for transport.

For alternate presentations, serve individual mini pies or fill tartlet shells with the same filling and top with toasted almonds for a pretty finish.

How to store & freeze

Short-term: Store leftover pie loosely covered at room temperature for up to 24 hours. After that, refrigerate in an airtight container for up to 4 days. Fruit pies with a buttery or cream topping should be refrigerated to preserve texture and food safety.
Freezing: To freeze a whole baked pie, cool completely, wrap tightly in plastic wrap and foil, and freeze up to 3 months. Thaw overnight in the refrigerator and reheat at 325°F for 15–20 minutes if you want it warm.
Safe handling: Don’t leave cut pie at room temperature longer than 2 hours to avoid bacterial growth.

Pro chef tips

Prevent a soggy bottom: bake the pie on a preheated rimmed baking sheet and consider briefly blind-baking the crust for 8–10 minutes if your crust is very soft.
Thickening the filling: use 2 teaspoons cornstarch instead of flour for a glossier, firmer filling.
Even browning: rotate the pie halfway through baking for uniform color.
Streusel texture: use cold butter grated into the dry ingredients for a crunchier topping, or softened butter for a crumblier, cohesive top.
Flavor boost: a pinch of ground ginger or a splash of almond extract enhances the fruitiness without overpowering the strawberries.

I also keep a second version on hand that uses more oats and a little lemon zest for extra brightness — see the classic strawberry rhubarb pie variations if you want a nuttier crumble.

Creative twists

Vegan: use vegan butter or chilled coconut oil in the streusel and a plant-based crust.
Boozy boost: macerate the fruit with 1–2 tablespoons of Grand Marnier or Cointreau for a grown-up aroma.
Nutty top: fold 1/4 cup chopped toasted almonds or pecans into the streusel.
Lattice or double crust: swap the crumble for a lattice top brushed with egg wash (or aquafaba for vegan) for a more traditional look.
Mini versions: bake in muffin tins lined with crust for handheld pies — reduce bake time to 25–30 minutes.

For a slightly different take with the same core flavors, try baking it as a slab pie or in a deep-dish pan.

Helpful answers

Q: Can I use frozen strawberries or rhubarb?
A: Yes. Thaw and drain excess liquid before using to avoid a runny filling. Toss partially thawed fruit with the sugar and a little extra thickener (cornstarch) to compensate.

Q: How long should the pie cool before slicing?
A: Let it cool at least 1.5–2 hours at room temperature. Cooling allows the filling to set so slices come out cleaner. If you’re impatient, refrigerate for 1 hour to speed it up.

Q: My filling was too runny — how do I fix that next time?
A: Use cornstarch (2 teaspoons) or increase the flour by another tablespoon. Also, make sure you macerate and drain some juice if using very ripe fruit.

Q: Can I make the pie ahead?
A: Yes. Assemble the pie and refrigerate up to 12 hours before baking; add 5–10 minutes to the baking time. Alternatively, bake fully, cool, and refrigerate for up to 4 days.

Q: Is this safe for a potluck?
A: Yes, as long as you don’t leave the pie out longer than 2 hours: keep it covered and move to refrigeration afterward.
