How to Make Easy Rhubarb Crisp Recipe with Oat Topping
- Prepare the rhubarb: Preheat your oven to 375°F (190°C). Trim the rhubarb and cut it into 1-inch pieces. In a large skillet, combine the rhubarb, sugar, lemon juice, and a pinch of salt. Cook over medium heat until the rhubarb is tender and the mixture has thickened, about 5-7 minutes. Transfer the rhubarb to a 9-inch pie dish or baking dish and set aside.
- Make the topping: In a medium bowl, combine the oats, flour, brown sugar, cinnamon, and a pinch of salt. Add the melted butter and stir until the mixture resembles coarse crumbs. If the topping is too dry, add a bit more melted butter. If it's too wet, add a bit more oats.
- Assemble and bake: Sprinkle the oat topping evenly over the rhubarb. Bake for 25-30 minutes, or until the topping is golden and crispy. Let the crisp cool for a few minutes before serving. Enjoy with a scoop of vanilla ice cream or a dollop of whipped cream, if desired.
