Ingredients
For the Rhubarb Filling:
6 cups (about 1.5 lbs) fresh rhubarb, trimmed and chopped into 1/2-inch pieces
1/2 cup (100g) granulated sugar
2 tablespoons cornstarch
1 teaspoon vanilla extract
For the Crumble Topping:
1 cup (90g) rolled oats (old-fashioned oats)
1 cup (120g) all-purpose flour
1/2 cup (100g) light brown sugar, packed
1/2 teaspoon salt
1/2 cup (113g) unsalted butter, cold and cut into small cubes
Instructions
Step 1: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
Step 2: In a large bowl, combine the chopped rhubarb, granulated sugar, cornstarch, and vanilla extract. Toss gently until the rhubarb is evenly coated. Pour the mixture into the prepared baking dish and spread it in an even layer.
Step 3: In a separate medium bowl, combine the rolled oats, all-purpose flour, light brown sugar, and salt. Whisk until well combined.
Step 4: Add the cold, cubed butter to the dry crumble ingredients. Using your fingertips or a pastry blender, work the butter into the mixture until coarse crumbs form, with some pea-sized pieces of butter remaining.
Step 5: Evenly sprinkle the crumble topping over the rhubarb filling in the baking dish.
Step 6: Bake for 40-50 minutes, or until the rhubarb is tender and bubbly, and the topping is golden brown and crisp. If the topping starts to brown too quickly, loosely tent the dish with aluminum foil.
Step 7: Remove from the oven and let cool slightly before serving. This allows the filling to set. Serve warm with your favorite accompaniments.
Notes
For best results, use fresh, firm rhubarb. You can substitute half of the rhubarb with strawberries for a classic strawberry-rhubarb crumble. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days and reheated gently.
