Step 2: Prepare the Filling

How to Serve Rhubarb Crisp
Rhubarb Crisp is a delightful dessert that can be enjoyed in various ways. Whether you’re serving it at a family gathering or enjoying a quiet evening at home, these serving suggestions will elevate your experience.
Classic with Ice Cream
- Serve warm with a scoop of vanilla ice cream on top for a creamy contrast to the tart rhubarb.
Fresh Whipped Cream
- Add fresh whipped cream as an alternative to ice cream; its lightness complements the dish beautifully.
Yogurt Topping
- For a healthier option, try Greek yogurt drizzled with honey; it adds protein and sweetness.
Nutty Crunch
- Sprinkle toasted nuts like almonds or walnuts on top for added texture and flavor.
Berry Garnish
- Top with fresh berries, such as strawberries or blueberries, to enhance the fruity flavors of the crisp.
Drizzle of Caramel Sauce
- A light caramel drizzle can add an extra layer of sweetness that pairs perfectly with the tartness of the rhubarb.

How to Perfect Rhubarb Crisp
To ensure your Rhubarb Crisp turns out perfectly every time, follow these essential tips.
-
Use fresh rhubarb: Fresh rhubarb gives the best flavor and texture. If using frozen, make sure it’s fully thawed and drained.
-
Adjust sugar levels: Depending on your taste preference, feel free to tweak the amount of sugar. Some may prefer a sweeter dish while others enjoy it more tart.
-
Mix thoroughly: Ensure that the sugar and corn starch are well combined with the rhubarb for even sweetness and thickening.
-
Check baking time: Keep an eye on your crisp during baking; oven temperatures can vary. Look for golden brown topping as a sign it’s ready.
-
Let it rest: After baking, allow the crisp to sit for about 10 minutes before serving. This helps thicken the juices for better serving.
-
Experiment with toppings: Consider adding spices like cinnamon or nutmeg to your oat topping for an extra flavor dimension.
Best Side Dishes for Rhubarb Crisp
While Rhubarb Crisp is a delightful dessert on its own, pairing it with certain side dishes can enhance your meal. Here are some great options:
-
Cheese Platter: A selection of cheeses like brie or goat cheese provides a savory contrast to the sweet crisp.
-
Savory Salad: A fresh green salad with vinaigrette balances out the sweetness of dessert and adds freshness.
-
Grilled Chicken: Lightly seasoned grilled chicken brings protein to your meal, complementing the sweet flavors of Rhubarb Crisp nicely.
-
Roasted Vegetables: Roasted seasonal vegetables offer earthy flavors that pair well with all desserts, including this one.
-
Pasta Salad: A chilled pasta salad can add substance and variety, making your meal feel more complete.
-
Fruit Salad: A mix of seasonal fruits serves as a refreshing side that harmonizes beautifully with Rhubarb Crisp’s tartness.
-
Bread Rolls: Soft bread rolls provide a comforting side option that can soak up any extra juices from the crisp.
-
Ice Cream Sundae Bar: Set up an ice cream sundae bar for guests to create their own perfect dessert alongside Rhubarb Crisp.
Common Mistakes to Avoid
When making Rhubarb Crisp, it’s easy to overlook some crucial steps. Here are common mistakes to avoid for the best results.
- Using too much cornstarch: If using fresh rhubarb, stick to 2 tablespoons of cornstarch. Excess starch can make the filling too thick.
- Not preheating the oven: Always preheat your oven to ensure even cooking. This helps achieve that perfect golden brown topping.
- Skipping the cooling time: Allowing the crisp to cool for 10 minutes after baking helps it set up properly and makes serving easier.
- Rushing the topping preparation: Mixing until crumbly is key. Don’t overwork it; otherwise, it may turn out dense instead of light and crispy.
- Ignoring ingredient temperature: Make sure your butter is cold when mixing with dry ingredients. This ensures a flaky topping.
