Ingredients
  

For the Filling:

  • 4 cups rhubarb cut into bite-sized pieces
  • 1 cup granulated sugar adjust based on tartness of rhubarb
  • 1 tbsp cornstarch for thickening
  • 1 tsp vanilla extract for a hint of warmth
  • Zest of 1 orange for a citrusy lift

For the Crumble Topping:

  • 1 cup all-purpose flour sifted
  • 1/2 cup rolled oats for texture
  • 2/3 cup brown sugar for a rich molasses flavor
  • 1/2 tsp ground cinnamon for spice
  • 1/4 tsp salt to balance sweetness
  • 1/2 cup unsalted butter chilled and diced

Instructions
 

  • Prepare the Filling: In a large mixing bowl, combine the rhubarb pieces with granulated sugar, cornstarch, vanilla extract and orange zest. Toss until the rhubarb is evenly coated. Let the mixture sit for about 10 minutes to macerate, drawing out the juices and enhancing the flavor.
  • Make the Crumble Topping: In a separate bowl, mix together the flour, rolled oats, brown sugar, ground cinnamon and salt. Add the chilled, diced butter. Use a pastry blender or fork to cut the butter into the dry ingredients until the mixture resembles coarse crumbs with some larger pieces of butter remaining.
  • Assemble: Transfer the rhubarb mixture into the baking dish, spreading it out evenly. Sprinkle the crumble topping over the rhubarb, covering it completely.
  • Bake: Place the baking dish in the preheated oven. Bake for 35-40 minutes, or until the crumble topping is golden brown and the rhubarb filling is bubbling around the edges.
  • Serve: Allow the crumble to cool slightly before serving. It’s best enjoyed warm, perhaps with a scoop of vanilla ice cream or a dollop of whipped cream for an indulgent touch.

Notes

Rhubarb’s tartness varies, so taste your rhubarb and adjust the sugar accordingly. If you prefer a less sweet dessert, you can reduce the sugar in the filling slightly.
The addition of orange zest adds a beautiful citrus note to the crumble, but you can also experiment with lemon zest or even a splash of port wine for a deeper flavor profile.
Enjoy crafting this sumptuous Rhubarb Crumble, a dessert that celebrates the delightful tartness of rhubarb paired with a sweet, crunchy topping. It’s a recipe sure to impress and satisfy any dessert lover.
