This rhubarb crisp recipe is a delicious spring dessert! It has a tart, jammy rhubarb filling with a buttery oat crumble on top. Serve it with a scoop of vanilla ice cream or whipped cream for the perfect balance of sweet and tangy flavors.
Preheat the oven to 375°F and grease an 8x8-inch baking dish.
In a large bowl, toss the rhubarb with the sugar, cornstarch, and orange juice and zest. Spread evenly in the prepared baking dish.
Make the topping: In a medium bowl, combine the flour, brown sugar, oats, walnuts, cinnamon, and salt. Use your hands to work in the butter until the mixture is crumbly and holds together when pinched.
Sprinkle the topping over the rhubarb mixture and bake for 25 to 35 minutes, or until the topping is golden brown and the rhubarb is soft and bubbling.
Remove from the oven and let cool for 5 minutes. Serve with vanilla ice cream.
Notes
*Make it gluten-free: Replace the all-purpose flour with almond flour. Reduce the butter to 1/4 cup. If the crumble feels dry, add water, 1/2 teaspoon at a time, as needed to help it come together.**Make it dairy-free: Replace the butter with firm coconut oil.
