Scottish Rhubarb Crumble with Oats - Scotland traditional dish

🧂 Ingredients

  • 1 kg Fresh rhubarb(trimmed and cut into 2-3cm pieces)
  • 150 g Granulated sugar(divided)
  • 50 ml Water
  • 150 g Rolled oats
  • 100 g Plain flour
  • 125 g Unsalted butter(cold and cubed)
  • 50 g Brown sugar
  • 1 tsp Ground cinnamon

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 190°C (170°C fan/Gas Mark 5).

    💡 Tip: Ensure oven is fully preheated before baking.
  2. 2

    Place the chopped rhubarb in a saucepan with 100g of the granulated sugar and the water. Cook gently for 5-10 minutes until the rhubarb has softened slightly but still holds its shape.

    ⏱️ 10 minutes
    💡 Tip: Avoid overcooking the rhubarb, as it will continue to cook in the oven.
  3. 3

    Pour the cooked rhubarb and its juices into a baking dish (approximately 20x30cm).

  4. 4

    In a separate bowl, combine the rolled oats, plain flour, brown sugar, ground cinnamon, and the remaining 50g of granulated sugar.

    💡 Tip: Using a mix of sugars adds depth of flavour.
  5. 5

    Add the cold, cubed butter to the dry ingredients. Rub the butter into the flour mixture using your fingertips until it resembles coarse breadcrumbs. Alternatively, pulse in a food processor.

    💡 Tip: Keep the butter cold for a crispier crumble topping.
  6. 6

    Scatter the crumble topping evenly over the rhubarb in the baking dish.

    💡 Tip: Ensure an even layer for consistent baking.
  7. 7

    Bake in the preheated oven for 35-40 minutes, or until the topping is golden brown and crisp, and the rhubarb is bubbling.

    ⏱️ 40 minutes
    💡 Tip: If the topping browns too quickly, loosely cover with foil.
  8. 8

    Let the crumble cool slightly before serving. It is best served warm.

    💡 Tip: Allowing it to rest for a few minutes helps the juices settle.

💡 Pro Tips

  • For a richer flavour, add a handful of chopped nuts (like almonds or walnuts) to the crumble topping.
  • Serve with custard, vanilla ice cream, or a dollop of thick cream.
  • If rhubarb is very tart, you may need to increase the sugar slightly.

🔄 Variations

  • Add a few strawberries or raspberries to the rhubarb mixture for a fruity twist.
  • Incorporate a teaspoon of mixed spice into the crumble topping for extra warmth.
  • Use a mix of white and brown sugar in the topping for a deeper caramel note.
