Ingredients
- 3 cups, cut into 1/2-inch pieces rhubarb
- 2 cups, hulled and halved strawberries
- 1/2 cup granulated sugar
- 1/4 cup all-purpose flour
- 1/2 cup rolled oats
- 1/4 cup, cold and cubed unsalted butter
- 1/2 tsp ground cinnamon
- 1/4 tsp salt
Instructions
- Step 1: Preheat oven to 375°F (190°C). In a 9x13-inch baking dish, combine 3 cups diced rhubarb, 2 cups halved strawberries, 1/2 cup granulated sugar, and 1/4 cup all-purpose flour, stirring until sugar dissolves and fruit is coated.
- Step 2: In a medium bowl, mix 1/2 cup rolled oats, 1/4 tsp ground cinnamon, and 1/4 tsp salt. Cut in 1/4 cup cold cubed unsalted butter with a pastry cutter until mixture resembles coarse crumbs.
- Step 3: Sprinkle the oat crumble mixture evenly over the fruit filling, pressing gently to form a compact layer.
- Step 4: Bake for 40-45 minutes until fruit is bubbling around the edges and topping is golden brown, rotating the dish halfway through.
- Step 5: Let cool for 15 minutes before serving, allowing the filling to set. Serve with vanilla ice cream if desired.
