Ingredients

Scale
  • 4 cups fresh rhubarb, chopped into 1/2-inch pieces
  • 3 cups fresh strawberries, hulled and halved
  • 3/4 cup granulated sugar
  • 2 tablespoons cornstarch
  • 1 teaspoon pure vanilla extract
  • 1 tablespoon fresh lemon juice
  • 1 cup old-fashioned rolled oats
  • 1/2 cup all-purpose flour
  • 1/2 cup light brown sugar, packed
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 6 tablespoons unsalted butter, melted and slightly cooled

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. In a large bowl, combine the chopped rhubarb and halved strawberries. Sprinkle the granulated sugar and cornstarch over the fruit, then drizzle with lemon juice and vanilla extract. Toss gently to coat evenly.
  3. Transfer the fruit mixture to a 9×9-inch baking dish and spread it out evenly, pressing down lightly.
  4. In a separate bowl, whisk together the rolled oats, flour, brown sugar, cinnamon, and salt. Pour in the melted butter and stir until the mixture clumps into crumbly bits.
  5. Sprinkle the oat topping evenly over the fruit filling, covering it entirely.
  6. Bake for 40–45 minutes until the topping is golden brown and the fruit filling bubbles around the edges. If the topping browns too fast, cover loosely with foil for the last 10 minutes.
  7. Let the crisp cool for at least 15 minutes before serving to allow the fruit juices to thicken.

Notes

Use old-fashioned rolled oats for best texture. Do not overmix the topping to keep it crumbly. If topping browns too quickly, cover with foil. Let crisp rest after baking to thicken filling. Frozen fruit can be used if thawed and drained. For gluten-free, substitute flour with almond or coconut flour and butter with dairy-free alternative.
