Ingredients

Scale
  • 3 cups fresh strawberries, hulled and halved
  • 3 cups rhubarb stalks, chopped into 1/2-inch pieces
  • 3/4 cup granulated sugar
  • 2 tablespoons cornstarch
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon (optional)
  • 1 cup old-fashioned rolled oats
  • 3/4 cup all-purpose flour
  • 1/2 cup packed light brown sugar
  • 1/2 teaspoon salt
  • 1/2 teaspoon ground cinnamon
  • 1/2 cup unsalted butter, cold and cut into cubes

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. In a large mixing bowl, combine the halved strawberries and chopped rhubarb. Add 3/4 cup granulated sugar, 2 tablespoons cornstarch, 1 teaspoon vanilla extract, and 1/2 teaspoon cinnamon. Gently toss everything together until the fruit is evenly coated.
  3. Transfer the fruit mixture to your 9×9 inch baking dish. Spread it out evenly.
  4. In a separate bowl, mix 1 cup rolled oats, 3/4 cup all-purpose flour, 1/2 cup packed light brown sugar, 1/2 teaspoon salt, and 1/2 teaspoon cinnamon.
  5. Add the cold butter cubes to the dry ingredients. Using a pastry cutter or your fingers, work the butter into the mixture until it resembles coarse crumbs with some pea-sized clumps.
  6. Evenly sprinkle the streusel over the fruit filling without pressing down.
  7. Bake the crisp in the preheated oven for 35-40 minutes until the fruit is bubbling and the topping is golden brown. If the topping browns too fast, tent with foil and continue baking.
  8. Remove from the oven and let cool for 10-15 minutes to thicken the filling.
  9. Serve warm, ideally with a scoop of vanilla ice cream or whipped cream.

Notes

Keep the butter cold for a crumbly topping. Use cornstarch to prevent watery filling. Tent with foil if topping browns too quickly. Adjust sugar to taste depending on fruit sweetness. Can substitute flour and butter for gluten-free or dairy-free versions.
