Ingredients
- 6 cups fresh rhubarb, chopped into 1/2-inch pieces
- 1 cup granulated sugar
- 1/4 cup all-purpose flour
- 1 teaspoon ground cinnamon (optional, for filling)
- 1 cup all-purpose flour
- 1/2 cup packed light brown sugar
- 1/2 cup granulated sugar
- 1 cup rolled oats
- 1/2 teaspoon ground cinnamon (for topping)
- 1/2 cup unsalted butter, cold and cut into cubes
- Pinch of salt (optional, for topping)
Step-by-Step Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- In a large bowl, combine the chopped rhubarb, 1 cup granulated sugar, 1/4 cup flour, and 1 teaspoon optional cinnamon. Toss gently until the rhubarb is evenly coated.
- Pour the rhubarb mixture into the prepared baking dish, spreading it out into an even layer.
- In a separate medium bowl, combine the 1 cup flour, brown sugar, 1/2 cup granulated sugar, rolled oats, 1/2 teaspoon cinnamon, and optional pinch of salt.
- Add the cold, cubed butter to the dry topping ingredients. Using your fingers, a pastry blender, or a fork, cut the butter into the mixture until it resembles coarse crumbs with some larger pieces.
- Evenly sprinkle the oat topping over the rhubarb mixture in the baking dish.
- Bake for 45-55 minutes, or until the topping is golden brown and the rhubarb filling is bubbly and tender when pierced with a fork.
- Remove from the oven and let cool for at least 15-20 minutes before serving. This allows the filling to set slightly.
Expert Tips / Pro Tips
For the best texture, ensure your butter for the topping is very cold and cut into small cubes. This helps create that delightful crumbly crispness. Don’t overmix the topping once the butter is added; larger pea-sized pieces of butter will melt and create pockets of deliciousness. If your rhubarb is particularly tart, you can add an extra tablespoon or two of sugar to the filling. To prevent the topping from getting too dark, you can loosely tent the crisp with aluminum foil during the last 15-20 minutes of baking if needed. Allowing it to cool properly before serving is key for the filling to thicken up, preventing a watery crisp.
Variations & Substitutions
Feel free to experiment with this versatile recipe! For a gluten-free option, use a gluten-free all-purpose flour blend approved for baking and certified gluten-free oats. You can add other fruits to the filling, such as strawberries, raspberries, or blueberries, which pair wonderfully with rhubarb. For extra flavor in the topping, try adding a pinch of nutmeg or cardamom. A handful of chopped nuts like almonds, pecans, or walnuts can also be blended into the topping for added crunch. If you don’t have fresh rhubarb, frozen rhubarb can be used; just make sure to thaw and drain any excess liquid before mixing it with the other filling ingredients.
Serving Suggestions
This Irresistible Rhubarb Crisp is a delightful dessert on its own, but it truly shines when served warm with a scoop of vanilla bean ice cream. The cold, creamy ice cream melting into the warm, tart crisp is an experience not to be missed. A dollop of freshly whipped cream or a drizzle of crème anglaise also makes for an elegant accompaniment. For a simpler yet equally satisfying serving, a spoonful of plain Greek yogurt can add a lovely tang that complements the rhubarb beautifully.
Storage, Freezing & Reheating
Store any leftover rhubarb crisp covered tightly with plastic wrap or aluminum foil at room temperature for up to 2 days, or in the refrigerator for up to 4-5 days. To freeze, allow the crisp to cool completely. Wrap it tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 3 months. To reheat, thaw frozen crisp in the refrigerator overnight. Reheat individual portions in the microwave until warm, or for a whole crisp, cover loosely with foil and bake in a preheated oven at 300°F (150°C) for about 20-30 minutes, or until heated through and the topping is crisp again.

FAQ
Can I use frozen rhubarb for this recipe?
Yes, you can use frozen rhubarb. Thaw it completely and drain any excess liquid before mixing it with the other filling ingredients to prevent the crisp from becoming watery.
How do I know when the rhubarb crisp is done baking?
The crisp is done when the topping is golden brown, and the rhubarb filling is bubbly and tender. You can gently poke the filling with a knife or fork to check for tenderness.
Can I make this rhubarb crisp ahead of time?
Yes, you can prepare the crisp and bake it a day in advance. Let it cool completely, then cover and store at room temperature or in the refrigerator. Reheat gently before serving for the best texture.
Why is my crisp topping not crispy?
Ensure your butter is cold when you cut it into the topping ingredients. Also, avoid overmixing, which can cause the butter to melt and make the topping less crumbly. Baking until deeply golden brown is also key for crispness.

Irresistible Rhubarb Crisp Recipe
Ingredients
Method
- Preheat your oven to 375°F (190°C). Lightly butter a 9×13-inch baking dish.
- In a large bowl, combine the chopped rhubarb, granulated sugar, 1/4 cup all-purpose flour, vanilla extract, and 1/4 teaspoon ground cinnamon. Toss gently to coat the rhubarb evenly. Pour the mixture into the prepared baking dish and spread it in an even layer.
- To prepare the crisp topping, in a separate medium bowl, whisk together 1 cup all-purpose flour, brown sugar, granulated sugar, 1/2 teaspoon ground cinnamon, and salt.
- Add the cold, cubed butter to the dry ingredients. Using your fingertips or a pastry blender, cut the butter into the flour mixture until coarse crumbs form. Some larger pea-sized clumps are desirable for a good crisp texture.
- Sprinkle the crumb topping evenly over the rhubarb mixture in the baking dish.
- Bake for 45-55 minutes, or until the topping is golden brown and the rhubarb filling is bubbly and tender when pierced with a fork. If the topping starts to brown too quickly, you can loosely tent it with aluminum foil.
- Remove from the oven and let it cool for at least 15-20 minutes before serving. This allows the filling to set slightly. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream, if desired.
