Easy Rhubarb Crisp with Oat Streusel (5-Ingredient)
This delightful rhubarb crisp uses only five ingredients for a quick and easy dessert. The tartness of the rhubarb is perfectly balanced by a sweet and crunchy oat streusel.
Equipment
- large bowl
- medium bowl
- 2-quart baking dish
- pastry blender (optional)
Ingredients
Filling
- 6 cups rhubarb, trimmed and chopped
- 1 cup granulated sugar
Streusel
- 1 cup old-fashioned oats
- 0.5 cup all-purpose flour
- 0.5 cup cold unsalted butter, cut into cubes
Instructions
Prepare the Rhubarb Filling
- Toss chopped rhubarb and granulated sugar together in a large bowl, then set aside to macerate while you prepare the streusel.
Make the Oat Streusel
- Combine old-fashioned oats, all-purpose flour, and cold unsalted butter cubes in a medium bowl; mix until streusel forms using your hands or a pastry blender.
Assemble and Bake
- Transfer the sugared rhubarb to a 2-quart baking dish and sprinkle the oat streusel evenly over the top.
- Bake at 375°F (190°C) for 35-40 minutes, or until the rhubarb is tender and the topping is golden brown.
Cool and Serve
- Allow the crisp to cool for at least 15 minutes before serving warm, optionally with a scoop of vanilla ice cream.
Notes
For extra flavor, a pinch of cinnamon or nutmeg can be added to the streusel. This crisp is best served warm with a dollop of whipped cream or vanilla ice cream.
