Ingredients

  • Filling
  • 5 cups chopped rhubarb
  • ¾ cup granulated sugar
  • 2 tablespoons cornstarch
  • 1 teaspoon vanilla extract
  • 1 tablespoon lemon juice
  • ½ teaspoon cinnamon optional
  • Topping
  • 1 cup rolled oats
  • 1 cup all-purpose flour
  • ¾ cup brown sugar
  • ½ teaspoon cinnamon
  • ¼ teaspoon salt
  • ½ cup cold unsalted butter cubed

Instructions

  • Preheat oven to 350°F (175°C) and grease a baking dish.
  • Mix rhubarb with sugar, cornstarch, vanilla, lemon juice, and cinnamon. Spread into the baking dish.
  • Combine oats, flour, brown sugar, cinnamon, and salt. Cut in butter until crumbly.
  • Sprinkle the topping evenly over the rhubarb.
  • Bake for 40–45 minutes until golden and bubbly.
  • Cool for 10–15 minutes and serve warm.

Notes

  • Fresh rhubarb provides the best flavor and texture.
  • Frozen rhubarb works well if thawed and drained.
  • Don't press down the topping—this helps it bake up crisp and crunchy.
  • Let the crisp cool slightly before serving so the filling can set.
