Ingredients You’ll Need
This Rhubarb Crisp Recipe calls for straightforward ingredients that come together beautifully to create its classic flavor and texture. Each component plays a critical role—from the tartness of the rhubarb to the buttery crumble on top, making this dessert as delightful to make as it is to eat.
- 3 cups diced fresh rhubarb: The star of the dish, offering tartness and vibrant color that is essential for the crisp.
- ½ cup white sugar: Balances the tartness of the rhubarb, adding just the right amount of sweetness.
- 1 tablespoon all-purpose flour: Helps thicken the rhubarb juices during baking so they’re perfectly luscious.
- 1 tablespoon water: Assists in evenly coating the rhubarb mixture for uniform cooking.
- 1 teaspoon ground cinnamon: Adds comforting warmth that complements the fruit’s tartness beautifully.
- 1 teaspoon ground allspice (optional): For those who love a slightly spiced touch, it deepens the complexity of flavors.
- ¾ cup rolled oats: Creates the crunchy, hearty topping that contrasts so nicely with the soft rhubarb.
- ½ cup all-purpose flour: Provides structure to the crisp topping, helping it hold together.
- ½ cup brown sugar, packed: Gives the topping a rich sweetness and a touch of molasses flavor.
- ¼ teaspoon salt: Enhances all the flavors, balancing sweetness and tartness.
- ½ cup unsalted butter, cold and cubed: The secret to a tender, crumbly topping that browns perfectly in the oven.
How to Make Rhubarb Crisp Recipe
Step 1: Preheat and Prepare Your Oven
Set your oven to 350°F (175°C) so it’s nice and hot when you’re ready to bake. Preheating is key for a crisp top that gets golden and crunchy just right, while the rhubarb filling bubbles away underneath.
Step 2: Mix the Rhubarb Filling
In a mixing bowl, combine your diced fresh rhubarb with white sugar, flour, water, cinnamon, and allspice if you’re using it. Toss everything together until the rhubarb pieces are coated evenly. This step ensures the flavors meld and the juices thicken nicely as it bakes.
Step 3: Transfer to Baking Dish
Grease an 8×8-inch baking dish to prevent sticking, then pour in your rhubarb mixture. Spread it out evenly; this will become the luscious, bubbly base of your crisp.
Step 4: Prepare the Crisp Topping
In a separate bowl, combine rolled oats, flour, brown sugar, and salt. Add the cold cubed butter, then use a pastry cutter or your fingers to work it in until the mixture forms coarse crumbs. This cold butter is what gives the topping its irresistible crumbly texture.
Step 5: Assemble and Bake
Sprinkle the oat mixture evenly over your rhubarb filling, covering it completely. Pop the whole dish into the oven and bake for 35 to 40 minutes. You’ll know it’s done when the top is golden brown and you see the rhubarb bubbling around the edges—pure perfection.
Step 6: Cool and Serve
Allow the crisp to cool just slightly before serving. This resting time lets the juices thicken a little more while keeping everything warm and inviting. Don’t forget a scoop of vanilla ice cream or a spoonful of whipped cream to take it over the top!
How to Serve Rhubarb Crisp Recipe

Garnishes
One of the joys of this Rhubarb Crisp Recipe is how easy it is to dress it up: a scoop of creamy vanilla ice cream melting over the warm crisp is unbeatable. Alternatively, a dollop of lightly sweetened whipped cream or a sprinkle of toasted nuts adds texture and a touch of elegance.
Side Dishes
This crisp makes a wonderful finale to many meals, but it can also stand alongside a simple cup of coffee or tea for a cozy afternoon treat. For a brunch spread, try it with fresh fruit salad or yogurt to balance the richness.
Creative Ways to Present
Get playful by serving individual portions in small ramekins or mason jars for a charming presentation. You can also layer the crisp with yogurt or custard for a parfait-style dessert that looks as good as it tastes.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers (which sometimes is hard to imagine), store them in an airtight container in the refrigerator for up to 3 days. The crisp topping stays tasty, and the filling continues to sweeten as it rests.
Freezing
This Rhubarb Crisp Recipe freezes beautifully if you want to prepare it in advance. Bake it first, let it cool completely, then wrap tightly with foil or plastic wrap before placing it in the freezer. When you’re ready, thaw overnight in the fridge and warm it up before serving.
Reheating
To bring your crisp back to life, reheat it in a preheated oven at 350°F (175°C) for about 15 minutes or until warmed through and crisp on top. This method preserves that beautiful texture—microwaving can make it mushy, so the oven is definitely the way to go.
FAQs
