Ingredients:
- 3 cups (450g) fresh strawberries, hulled and halved
- 3 cups (400g) fresh rhubarb, sliced into ½-inch pieces
- ½ cup (100g) granulated sugar
- ⅓ cup (40g) all-purpose flour
- 1 tbsp (15ml) lemon juice
- 1 tsp (2g) ground cinnamon
- 1 cup (90g) old-fashioned rolled oats
- ¾ cup (95g) all-purpose flour
- ½ cup (100g) packed light brown sugar
- ½ cup (115g) unsalted butter, cold and cubed
- ¼ tsp (1.5g) salt
Instructions:
- Toss the halved strawberries and sliced rhubarb in a large bowl with the granulated sugar, flour, lemon juice, and cinnamon. Stir until the fruit is evenly coated and the flour has disappeared into the juices.
- Transfer the fruit mixture into the bottom of the slow cooker, spreading it into an even layer.
- In a separate bowl, whisk together the rolled oats, flour, brown sugar, and salt.
- Add the cold, cubed butter to the oat mixture. Use a pastry cutter or two forks to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized lumps of butter remaining.
- Sprinkle the crumble topping evenly over the fruit filling, ensuring you cover the edges to prevent the fruit from bubbling over the sides.
- Cover with a lid and cook on High for 50 minutes or Low for 3 hours. The dish is ready when the fruit filling is bubbling and the topping has shifted to a deep golden brown.
