How to Make Rhubarb Crisp
Step 1: Prep the Oven and Rhubarb
Preheat the oven to 350°F (177°C). If using frozen rhubarb, thaw and drain it well to avoid excess moisture. Place chopped rhubarb in a greased 9×9-inch baking dish.
Step 2: Mix the Filling
In a bowl, combine granulated sugar, cornstarch, and lemon juice. Pour this mixture over the rhubarb and toss until evenly coated. Set aside.
Step 3: Make the Crisp Topping
In a separate bowl, combine oats, flour, brown sugar, cinnamon, and salt. Add the cold butter cubes and use a pastry cutter or your fingers to mix until crumbly.
Step 4: Assemble and Bake
Sprinkle the crisp topping evenly over the rhubarb filling. Bake for 35–40 minutes, or until the top is golden brown and the fruit is bubbling.
Let it cool slightly before serving—warm is best with a scoop of vanilla ice cream or whipped cream.

Frequently Asked Questions
What is the difference between rhubarb crisp and crumble?
The main difference is in the topping. A crisp typically contains oats, creating a chunkier, more textured topping, while a crumble usually uses a streusel-like topping made with flour, butter, and sugar only.
Should you thaw rhubarb before making crisp?
Yes, if you’re using frozen rhubarb, thaw and drain it before baking. This helps reduce excess moisture and prevents a soggy filling.
What takes the tartness out of rhubarb?
Adding sugar and balancing rhubarb with sweeter fruits (like strawberries or apples) can help mellow its tartness. A small amount of honey or maple syrup also works well.
What enhances the flavor of rhubarb?
Bright flavors like lemon or orange zest, warm spices like cinnamon or nutmeg, and a touch of vanilla extract can all enhance rhubarb’s natural tang.
