Ingredients You’ll Need
The magic of this Rhubarb Crisp Recipe lies in its simplicity. Each ingredient plays an important role, creating layers of flavor and texture that come together beautifully. From the sharpness of fresh rhubarb to the buttery crisp topping, these essentials are easy to find and straightforward to use.
- 3 cups diced fresh rhubarb: Provides the tart, juicy star of the dish, balancing the sweetness perfectly.
- ½ cup white sugar: Sweetens the rhubarb filling and cuts through the natural tartness.
- 1 tablespoon all-purpose flour: Helps thicken the rhubarb juices so the filling isn’t runny.
- 1 tablespoon water: Ensures everything mixes smoothly and the filling is just the right consistency.
- 1 teaspoon ground cinnamon: Adds warmth and a subtle spice that complements the rhubarb beautifully.
- 1 teaspoon ground allspice (optional): For an extra depth of flavor, this little addition can really make the crisp special.
- ¾ cup rolled oats: Gives the topping its signature chewy texture and wholesome flavor.
- ½ cup all-purpose flour: Combines with oats and butter to create the crisp, golden crust.
- ½ cup brown sugar, packed: Brings a rich, caramel sweetness to the topping.
- ¼ teaspoon salt: Enhances all the flavors and balances the sweetness.
- ½ cup unsalted butter, cold and cubed: Essential for that crumbly, melt-in-your-mouth finish on top.
How to Make Rhubarb Crisp Recipe
Step 1: Preheat and Prepare Filling
Start by heating your oven to 350°F (175°C) to get it ready for baking. In a large mixing bowl, gently combine diced rhubarb with white sugar, flour, water, cinnamon, and allspice if you’re using it. Toss everything until the rhubarb pieces are evenly coated in this fragrant, lightly spiced mixture. This ensures every bite sings with flavor once baked.
Step 2: Transfer Filling to Baking Dish
Grease an 8×8-inch baking dish and pour the rhubarb mixture inside, spreading it out evenly. This is the juicy base of your crisp and will bubble up with luscious tartness as it bakes.
Step 3: Make the Crisp Topping
In a separate bowl, stir together the rolled oats, flour, brown sugar, and salt. Now for the fun part: add the cold, cubed butter. Use a pastry cutter or simply your fingers to work the butter into the dry ingredients until the mixture looks like coarse crumbs. This process is what creates the irresistible texture that crisps up beautifully in the oven.
Step 4: Assemble and Bake
Sprinkle the oat topping evenly over the rhubarb filling, covering it completely. Pop the crisp into your preheated oven and bake for 35 to 40 minutes. You’ll know it’s ready when the topping turns a gorgeous golden brown and the rhubarb filling bubbles enticingly at the edges.
Step 5: Cool Slightly Before Serving
Once baked, let your Rhubarb Crisp Recipe cool for a bit to set up. This brief rest makes serving easier and allows the flavors to meld gently. Serve warm with a generous scoop of vanilla ice cream or a dollop of whipped cream for maximum indulgence.
How to Serve Rhubarb Crisp Recipe

Garnishes
Adding a simple garnish takes your serving of rhubarb crisp to another level. Fresh mint leaves provide a pop of color and a refreshing hint that contrasts beautifully with the warm, spiced fruit. A sprinkle of toasted nuts like almonds or pecans adds a satisfying crunch and nutty undertone. Don’t forget a dusting of powdered sugar for that extra sweet touch!
Side Dishes
This crisp shines as a standalone dessert, but pairing it with a side can elevate the experience. A scoop of creamy vanilla ice cream or a dollop of whipped cream provides a soothing coolness against the warm crisp. For a brunch twist, pair it with a slightly tart Greek yogurt or a smooth custard to complement the rhubarb’s tang.
Creative Ways to Present
Want to impress your guests? Serve the crisp in individual ramekins for a personalized touch. Layer a scoop of ice cream between two spoonfuls of the crisp for a rhubarb-themed parfait. Or, transform leftovers into a decadent trifle by layering with whipped cream and cake cubes, turning your Rhubarb Crisp Recipe into a whole new experience.
Make Ahead and Storage
Storing Leftovers
Any leftover rhubarb crisp can be safely stored in the refrigerator for up to 3 days. Cover it tightly with plastic wrap or transfer to an airtight container to keep the topping crisp as long as possible.
Freezing
Planning ahead? You can prepare the crisp assembly but hold off on baking. Freeze it uncovered on a baking sheet until firm, then wrap it tightly with foil and store in a freezer-safe container for up to 2 months. When you’re ready, bake from frozen with a slightly longer baking time until golden and bubbly.
Reheating
To bring leftover rhubarb crisp back to life, heat individual portions in the microwave for about 30-45 seconds or warm in a 300°F (150°C) oven for 10-15 minutes. This restores warmth and revives that lovely crispy topping for a fresh-out-of-the-oven feel.
FAQs
Can I use frozen rhubarb for the Rhubarb Crisp Recipe?
Absolutely! Frozen rhubarb works just fine; just be sure to thaw and drain any excess liquid before mixing it with the other ingredients to avoid a soggy filling.
What can I substitute for rolled oats in the topping?
If you’re not a fan of oats or need a gluten-free option, chopped nuts or gluten-free cereal flakes can add a nice crunch to your crisp topping without compromising texture.
Is it possible to make this Rhubarb Crisp Recipe vegan?
Yes! Swap the butter for a plant-based margarine or coconut oil and use brown sugar that’s certified vegan to keep the crisp just as delicious and dairy-free.
How tart will the Rhubarb Crisp Recipe be?
The tartness depends on the rhubarb’s freshness and the sugar level you use, but overall this crisp strikes a lovely balance — tangy fruit mellowed by a sweet, warm topping.
Can I double the recipe?
Definitely, just use a larger baking dish or two separate ones. Keep the same baking temperature but expect a slightly longer bake time until the topping is golden and the filling bubbles.
