Strawberry Rhubarb Pie with Crumb Topping – Sweet, Tart, and Comforting

Strawberry rhubarb pie is one of those bakes that feels like spring in every bite. Sweet berries meet tart rhubarb, and the buttery crumb topping adds a cozy crunch. This version is easy enough for a weekend bake but special enough for a holiday table.

The filling sets up beautifully, the crust stays crisp, and the crumb is golden and fragrant. Serve it warm with ice cream or let it cool for tidy slices either way, it’s a crowd-pleaser.

What Makes This Recipe So Good

• Balanced flavor: The natural tartness of rhubarb plays perfectly with juicy, sweet strawberries.
• No-soggy-bottom crust: A little cornstarch and a brief rest help the filling thicken without watering down the crust.
• Crumb topping: Buttery, cinnamon-kissed crumbs give texture and extra flavor—no top crust to fuss with.
• Do-ahead friendly: Make the topping and prep the fruit ahead for easy assembly.
• Approachable: Simple steps, familiar ingredients, and reliable results.

Ingredients

• Pie Crust: 1 unbaked 9-inch pie shell (homemade or store-bought), chilled
• Filling:
  • 3 cups chopped rhubarb (about 1/2-inch pieces; fresh or frozen, thawed and drained)
  • 3 cups hulled and sliced strawberries
  • 3/4 to 1 cup granulated sugar (adjust to taste and fruit sweetness)
  • 1/4 cup cornstarch
  • 1 tablespoon lemon juice
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon fine salt
• Crumb Topping:
  • 3/4 cup all-purpose flour
  • 1/2 cup light brown sugar, packed
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon fine salt
  • 6 tablespoons cold unsalted butter, cubed
• Optional: 1 tablespoon coarse sugar for sprinkling

Instructions

1. Prep the oven and crust: Heat the oven to 400°F (200°C). Place a rack in the lower third.Set the chilled pie shell on a parchment-lined baking sheet.
2. Make the filling: In a large bowl, combine rhubarb, strawberries, sugar, cornstarch, lemon juice, vanilla, and salt. Gently toss until the fruit is evenly coated. Let it sit 10 minutes so the cornstarch hydrates.
3. Make the crumb topping: In a medium bowl, whisk flour, brown sugar, cinnamon, and salt.Cut in the cold butter with a pastry cutter or your fingers until clumps form and the mixture resembles coarse crumbs with pea-sized bits.
4. Assemble: Stir the filling again, then pour it into the pie shell, spreading evenly. Sprinkle the crumb topping over the fruit, covering it fully. Add coarse sugar on top if using.
5. Bake hot, then lower: Bake at 400°F for 20 minutes.Without opening the oven too long, reduce the temperature to 350°F (175°C) and continue baking 30–40 minutes, until the topping is deeply golden and the filling is bubbling thickly at the edges.
6. Shield if needed: If the crumbs or crust edge brown too fast, tent loosely with foil during the last 15–20 minutes.
7. Cool fully: Transfer the baked pie to a rack. Let it cool at least 3–4 hours to set the juices before slicing. For cleaner slices, cool to room temperature or chill briefly.
8. Serve: Enjoy plain, or with vanilla ice cream or lightly sweetened whipped cream.

Storage Instructions

• Room temperature: Keep covered for up to 1 day if your kitchen is cool.
• Refrigerator: Store covered for 3–4 days.The crumb stays firm if you keep it loosely tented to avoid condensation.
• Freezer: Wrap slices tightly and freeze up to 2 months. Thaw in the fridge, then warm in a 300°F oven for 10–15 minutes to refresh the crumb.

Benefits of This Recipe

• Seasonal produce: Uses spring and early summer fruit at its peak.
• Flexible sweetness: Easy to adjust sugar for tart or sweet preferences.
• Beginner-friendly: No lattice work or blind-baking required.
• Textural contrast: Juicy filling, crisp crust, and crunchy topping in every bite.

What Not to Do

• Don’t skip the cool-down: Cutting too soon leads to runny slices.
• Don’t overfill the crust: Too much fruit can overflow and soften the bottom.
• Don’t use warm butter for crumbs: Cold butter creates the best chunky crumble.
• Don’t forget the baking sheet: It catches drips and makes moving the pie easier.

Alternatives

• Gluten-free: Use a gluten-free pie crust and swap the crumb flour for a 1:1 gluten-free blend or finely ground almond flour.
• Oat crumble: Replace 1/3 cup of the crumb flour with old-fashioned oats for extra texture.
• Lower sugar: Cut sugar to 1/2 cup and add an extra 1 tablespoon cornstarch to help the set.
• Flavor twists: Add 1/2 teaspoon grated fresh ginger or swap vanilla for almond extract.
• Frozen fruit: Works well—thaw and drain excess liquid before mixing with cornstarch.

FAQ

How do I keep the bottom crust from getting soggy?

Use a chilled crust, bake on the lower rack, and make sure the filling is well mixed with cornstarch. Preheating a baking sheet or pizza stone can also help crisp the bottom.

Can I make the pie ahead?

Yes. Assemble up to the point of baking, then refrigerate for up to 4 hours. Add a few extra minutes to the initial bake. Or bake fully, cool, and store in the fridge; rewarm gently before serving.

What if my rhubarb is very tart?

Use the higher end of the sugar range and keep the lemon juice for brightness. You can also mix in an extra 1/2 cup strawberries for more natural sweetness.

Can I use tapioca instead of cornstarch?

Yes. Use 3 tablespoons instant tapioca. Let the filling sit 15 minutes before adding to the crust so the granules soften.

How do I know the pie is done?

Look for thick, slow bubbles around the edges and a deep golden-brown crumb. If the filling isn’t bubbling, it hasn’t fully thickened yet.
