- Total Time: 1h 5min
- Yield: One 9-inch crisp 1x
- Category: dessert
- Method: baking
- Cuisine: American
Ingredients
- For the Rhubarb Filling:
- 6 cups fresh rhubarb, chopped into 1-inch pieces (about 1 1/2 lbs)
- 3/4 cup granulated sugar
- 3 tablespoons all-purpose flour
- 1 teaspoon vanilla extract
- Zest of 1 orange (optional)
- For the Crisp Topping:
- 1 cup old-fashioned rolled oats
- 3/4 cup all-purpose flour
- 3/4 cup packed light brown sugar
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1/2 cup (1 stick) cold unsalted butter, cubed
Instructions
- Preheat oven to 375°F (190°C).
- Make the filling: In a large bowl, toss chopped rhubarb with granulated sugar, 3 tbsp flour, vanilla, and orange zest (if using) until evenly coated. Pour into a 9-inch pie dish or 2-quart baking dish.
- Make the topping: In a medium bowl, whisk together oats, 3/4 cup flour, brown sugar, cinnamon, and salt. Add cold, cubed butter. Use a pastry cutter, fork, or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized butter bits.
- Assemble: Sprinkle the oat topping evenly over the rhubarb filling. Do not press down.
- Bake: Place the dish on a baking sheet to catch drips. Bake for 40-50 minutes, until the filling is bubbling vigorously and the topping is deep golden brown.
- Rest: Let the crisp cool on a wire rack for at least 20-30 minutes before serving to allow the filling to set.
Notes
For frozen rhubarb, use without thawing; bake time may increase by 5-10 minutes. Ensure butter for topping is cold for a crumbly texture. Letting the crisp rest is crucial for a set, non-runny filling. Store covered at room temp for 1-2 days, in the fridge for up to 5 days, or freeze for up to 3 months.

Step-by-Step Instructions
Making this rhubarb crisp is a straightforward, joyful process. Here’s how to build your dessert layer by layer.
1. Prep the Rhubarb and Oven.
Start by preheating your oven to 375°F (190°C). This gives it plenty of time to come to the right temperature for a perfectly baked crisp. While it heats, wash your rhubarb and chop it into even, 1-inch pieces. Toss them into a large mixing bowl.
2. Make the Filling.
To the bowl with the rhubarb, add the granulated sugar, 3 tablespoons of flour, vanilla extract, and orange zest if using. The flour is crucial—it thickens the juicy rhubarb as it bakes, preventing a soupy bottom. Toss everything together until the rhubarb pieces are evenly coated. Pour this mixture into a 9-inch pie dish, a 9×9 square baking dish, or a similar 2-quart baking dish.
3. Create the Crisp Topping.
In a separate bowl, combine the rolled oats, ¾ cup flour, brown sugar, cinnamon, and salt. Whisk it together. Add the cold, cubed butter. Using a pastry cutter, your fingers, or even a fork, work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized bits of butter remaining. This uneven texture is the secret to a topping that’s both crunchy and tender.
4. Assemble and Bake.
Sprinkle the oat topping evenly over the rhubarb filling. Don’t press it down—let it stay loose and crumbly. Place the dish on a baking sheet (this catches any potential bubble-overs and makes handling easier). Bake for 40-50 minutes, or until the filling is bubbling vigorously around the edges and the topping is a deep, golden brown.
5. Rest and Serve.
This is the hardest but most important step! Let the rhubarb crisp rest for at least 20-30 minutes after pulling it from the oven. This allows the filling to set up beautifully, so you get perfect, non-runny slices or scoops. The wait is worth it, I promise.

Healthier Alternatives for the Recipe

- Lower Sugar: Reduce the granulated sugar in the filling to ½ cup and use a brown sugar substitute in the topping. The natural tartness of the rhubarb will be more pronounced.

Serving Suggestions
A warm rhubarb crisp is a dessert that truly stands on its own, but a few additions make it sublime.
- The Classic: A big scoop of vanilla ice cream melting into the warm crisp is non-negotiable for me.
- For Breakfast: Enjoy it chilled or at room temperature with a dollop of Greek yogurt for a delightful morning treat.
- Whipped Cream: A cloud of freshly whipped cream is a lighter, equally delicious topping.
- With Other Desserts: Serve it alongside simpler treats for a dessert spread. It pairs wonderfully with the creamy ease of my No-Bake Cookie Butter Icebox or the festive fun of New Years Eve Cake Ball Drops.
Common Mistakes to Avoid
A few small tips can guarantee your rhubarb crisp turns out perfect every time.
- Using Warm Butter: Your butter must be cold. If it’s soft or melted, the topping will bake into a greasy, solid layer instead of separate, crispy crumbles.
- Skipping the Flour in the Filling: This is your thickener. Without it, you’ll have a juicy, soupy base instead of a luscious, sliceable filling.
- Cutting the Rhubarb Too Small: One-inch pieces are ideal. Smaller pieces will break down too much during baking.
- Not Letting it Rest: I know it’s tempting, but slicing into a crisp right out of the oven leads to a filling that runs everywhere. Let it set.
- Over-mixing the Topping: Stop when you have a crumbly mixture with visible butter bits. Overworking it can make the topping tough.
Storing Tips for the Recipe
- Counter: Once completely cooled, cover the baking dish with foil or plastic wrap. The rhubarb crisp will keep at room temperature for 1-2 days.
- Refrigerator: For longer storage, refrigerate for up to 5 days. Reheat individual portions in the microwave or the whole dish, covered with foil, in a 300°F oven until warm.
- Freezer: This crisp freezes beautifully! Bake and cool it completely. Wrap the entire dish tightly in plastic wrap and then foil, or transfer portions to airtight containers. Freeze for up to 3 months. Thaw overnight in the fridge and reheat in the oven to restore the topping’s crunch.
- Make-Ahead: You can prepare the filling and the topping separately up to a day in advance. Store the filling covered in the fridge and the topping in a bag in the fridge. Assemble and bake when ready.

At the end of the day, this rhubarb crisp is about more than just a recipe. It’s about creating a moment of pure, simple joy around the table.

What goes well with rhubarb crisp?

How do you keep rhubarb crisp from getting soggy?
To prevent a soggy rhubarb crisp, ensure the rhubarb is well-drained, use a thickener like cornstarch or tapioca starch, and don’t overbake. A higher oven temperature for the last few minutes can also help crisp the topping.
Do you need to peel rhubarb for crisp?
