How To Make A Strawberry Rhubarb Crisp

  1. Prepare the filling: Toss chopped rhubarb and strawberries with granulated sugar, flour, lemon juice and vanilla if using. Spread the mixture in a greased 13×9-inch baking dish.
  2. Make the topping: In a bowl combine brown sugar, flour, oats, cinnamon, nutmeg and nuts if desired. Stir in melted butter until the mixture is crumbly and evenly moistened.
  3. Assemble and bake: Sprinkle the topping evenly over the fruit. Bake at 350°F (175°C) for about 35–40 minutes, until the fruit is bubbling and the topping is golden brown. Let cool 10–15 minutes before serving.

How To Serve Strawberry Rhubarb Crisp

Serve warm, straight from the oven, with a scoop of vanilla ice cream or a dollop of whipped cream. The contrast of hot fruit and cool ice cream makes this dessert especially comforting.

Storing and Freezing

  • Freeze: Once completely cooled, transfer to an airtight, freezer-safe container. Thaw at room temperature and reheat in a 350°F oven until warmed through.
