Ingredients
  

For the Filling:

  • 4 cups rhubarb chopped
  • 1 cup granulated sugar
  • ¼ cup cornstarch
  • 1 teaspoon vanilla extract
  • 1 tablespoon lemon juice

For the Crumble Topping:

  • 1 cup all-purpose flour
  • ½ cup rolled oats
  • ½ cup brown sugar
  • ½ teaspoon cinnamon
  • ½ cup unsalted butter melted
  • Pinch of salt

Additional:

  • 1 9-inch unbaked pie crust (homemade or store-bought)

Instructions
 

Step 1: Preheat and Prep

  • Preheat your oven to 375°F (190°C).
  • Place the pie crust into a 9-inch pie dish and flute the edges if desired.

Step 2: Make the Rhubarb Filling

  • In a large bowl, combine chopped rhubarb, sugar, cornstarch, vanilla extract, and lemon juice.
  • Mix until the rhubarb is well coated.
  • Pour the filling into the prepared pie crust.

Step 3: Make the Crumble Topping

  • In a medium bowl, stir together flour, oats, brown sugar, cinnamon, and salt.
  • Add melted butter and mix until crumbly.
  • Sprinkle the topping evenly over the rhubarb filling.

Step 4: Bake

  • Place the pie on a baking sheet to catch any drips.
  • Bake for 45–55 minutes, or until the filling is bubbly and the topping is golden brown.
  • If the crust or topping begins to brown too quickly, tent loosely with foil.

Step 5: Cool and Serve

  • Let the pie cool at room temperature for at least 2 hours to set.
  • Serve warm or chilled with whipped cream or vanilla ice cream.

Notes

  • Thickening Tip: Let the pie cool completely for the filling to fully set.
  • Crumble Variations: Add chopped nuts or coconut flakes to the topping.
  • Fruit Add-Ins: Mix in strawberries or apples for extra dimension.
  • Don’t Skip the Lemon Juice: It lifts the flavor and balances sweetness.
  • Frozen Rhubarb?: Drain well to avoid a soggy crust.
