Description

A classic, homestyle recipe for rhubarb crunch featuring a tart, tender filling topped with a buttery, oat-based crumble.


Ingredients

Scale
  • 4 cups fresh rhubarb, cut into 1-inch pieces
  • 1 cup granulated sugar (for filling)
  • 2 tablespoons all-purpose flour (for filling)
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour (for topping)
  • 1 cup rolled oats
  • 1 cup packed light brown sugar (for topping)
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup (1 stick) cold unsalted butter, cut into small pieces


Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease an 8×8 inch baking dish.
  2. In a large bowl, combine the cut rhubarb, 1 cup granulated sugar, 2 tablespoons flour, and vanilla extract. Toss gently to coat the rhubarb evenly.
  3. Pour the rhubarb mixture into the prepared baking dish and spread it into an even layer.
  4. In a separate medium bowl, prepare the topping. Combine the 1/2 cup flour, rolled oats, brown sugar, cinnamon, and salt. Mix these dry ingredients together with a fork.
  5. Cut the cold butter pieces into the dry topping mixture using a pastry blender or your fingertips until the mixture resembles coarse crumbs. Do not overmix; some pea-sized pieces of butter are desired.
  6. Sprinkle the topping mixture evenly over the rhubarb filling in the baking dish. Press lightly.
  7. Bake for 40 to 45 minutes, or until the topping is golden brown and the rhubarb filling is bubbling thickly around the edges.
  8. Remove from the oven and let it cool on a wire rack for at least 15 minutes before serving.

Notes

  • Serve warm with vanilla ice cream or heavy cream for the best experience.
  • If your rhubarb is very tart, you may slightly increase the granulated sugar in the filling to 1 1/4 cups.
  • For a richer topping flavor, substitute half of the all-purpose flour with whole wheat flour.
