Ingredients
- 2 pounds sliced rhubarb (fresh or frozen)
- ¼ cup cornstarch
- ¾ cup sugar
- ½ teaspoon ground cinnamon
- 1 cup oats
- ½ cup flour
- ½ cup sugar
- ½ teaspoon ground cinnamon
- 1 pinch salt
- 1 stick cold butter, cubed
Step-by-Step Instructions
Preparing the Ingredients
Start by preheating your oven to 400°F and lightly buttering a 2-quart casserole dish. In a large bowl, combine sliced rhubarb, cornstarch, sugar, and cinnamon, then mix until evenly coated. Spread the mixture into the prepared dish so it forms an even layer. In another bowl, combine oats, flour, sugar, cinnamon, and salt, then cut in the cold butter until the mixture forms crumbly pieces similar to coarse dough.
Cooking Instructions
Evenly scatter the crumble topping over the rhubarb filling, making sure to cover the surface fully. Place the dish in the oven and bake for about 35 minutes until the top turns golden and the filling bubbles around the edges. Once baked, remove the crisp from the oven and let it rest for 10 minutes so the filling thickens properly before serving.
Tips for Perfect Results
Common Mistakes to Avoid
Avoid using warm butter in the topping because it prevents the crumble from forming correctly. Do not skip draining thawed rhubarb if using frozen fruit, as excess moisture can make the filling watery. Also, resist reducing the sugar since rhubarb requires enough sweetness to balance its tartness. Skipping the resting time can lead to a runny texture, so patience pays off here.
Pro Tips for Better Flavor
Use quick oats for a softer, more cohesive topping, or pulse old-fashioned oats briefly for better texture. If your rhubarb releases extra liquid, add a bit more cornstarch to keep the filling thick. For added depth, sprinkle a touch more cinnamon or pair the crisp with a creamy topping like whipped cream or ice cream to complement this summer fruit crisp.
Serving and Storage
How to Serve
Serve Easy Rhubarb Crisp warm for the best flavor and texture. Pair it with a scoop of vanilla ice cream or a dollop of whipped cream to create a rich contrast with the tart filling. This dessert works beautifully for brunch, dinner parties, or seasonal celebrations.

How to Store Leftovers
Store leftover crisp covered at room temperature for up to two days. For longer storage, refrigerate it and reheat portions in the oven or microwave until warmed through. Keeping it covered helps maintain moisture while preserving the crisp topping.
Conclusion
Easy Rhubarb Crisp offers a simple yet satisfying dessert that highlights the bold flavor of rhubarb with a buttery, crumbly topping. With minimal prep and reliable results, it fits both everyday baking and special occasions. Try this recipe once, and it will likely become a seasonal favorite in your kitchen.

Frequently Asked Questions
Can I use frozen rhubarb for Easy Rhubarb Crisp?
Yes, you can use frozen rhubarb, but thaw it completely and drain excess liquid before mixing. This step helps maintain the correct texture and prevents the filling from becoming too watery during baking.
What makes the topping crumbly instead of dense?
Cold butter and proper mixing create the crumbly texture. Cutting the butter into the dry ingredients forms small pockets that bake into a crisp, golden topping rather than a dense layer.
Can I prepare Easy Rhubarb Crisp ahead of time?
You can assemble the dish ahead and refrigerate it before baking. When ready to serve, bake it fresh so the topping stays crisp and the filling cooks evenly.
