With Vanilla Ice Cream
- The classic pairing of warm Rhubarb Crisp with creamy vanilla ice cream adds a rich and sweet contrast to the tart rhubarb.
Drizzled with Caramel Sauce
- A drizzle of warm caramel sauce over your Rhubarb Crisp creates an indulgent treat that balances sweetness and tartness beautifully.
Topped with Whipped Cream
- Light and fluffy whipped cream complements the crisp, adding an airy texture that lightens the dish while enhancing its flavors.
Served with Greek Yogurt
- For a healthier option, serve your Rhubarb Crisp with a dollop of Greek yogurt. This adds creaminess and a tangy flavor that pairs well with the dish.
Accompanied by Fresh Berries

How to Perfect Rhubarb Crisp
To achieve the best results when making Rhubarb Crisp, here are some essential tips to keep in mind.
- Use Fresh Ingredients: Fresh rhubarb will provide the best flavor and texture. If you use frozen rhubarb, ensure it’s fully thawed and drained.
- Adjust Sugar Levels: Depending on your taste preference, adjust the sugar levels. If you prefer it less sweet, reduce the granulated sugar slightly.
- Mix Toppings Well: Ensure that your butter is cold when mixing with oats and flour; this helps create a crunchy topping.
- Don’t Overbake: Keep an eye on your Rhubarb Crisp as it bakes. Once it turns golden brown, remove it from the oven to prevent burning.
- Let It Sit: Allowing the crisp to sit for about 10 minutes after baking helps the filling thicken up slightly before serving.
- Experiment with Spices: Adding a pinch of cinnamon or nutmeg can enhance the flavors of your Rhubarb Crisp, giving it an extra depth.
Best Side Dishes for Rhubarb Crisp
While Rhubarb Crisp is delicious on its own, pairing it with complementary side dishes can enhance your meal. Here are some great options:
- Vanilla Ice Cream – A classic choice that brings creaminess to balance the tartness of rhubarb.
- Custard – Smooth custard provides richness and pairs beautifully with crispy toppings.
- Cheese Platter – A selection of cheeses can create an interesting contrast against the sweetness of the crisp.
- Fruit Salad – A refreshing fruit salad adds brightness and freshness to offset the warmth of the dessert.
- Pecan Pie Bars – These bars have a unique texture and flavor that complement Rhubarb Crisp nicely.
- Chocolate Cake – Rich chocolate cake serves as a decadent alternative for those who crave chocolate desserts.
- Lemon Sorbet – The zesty lemon sorbet offers a cool and refreshing finish after enjoying warm rhubarb crisp.
- Coffee or Tea – A warm beverage enhances dessert time and provides comfort alongside sweet treats.
Common Mistakes to Avoid
When making Rhubarb Crisp, it’s easy to make a few common mistakes. Here are some tips to help you achieve the best results.
- Using too much corn starch: If you’re using fresh rhubarb, reduce the corn starch to only 2 tablespoons. This will ensure your filling isn’t overly thick.
- Not greasing the pan: Failing to grease your pan can result in a sticky mess. Always lightly grease your baking dish to allow for easy serving.
- Overmixing the topping: Mixing the oat topping too much can lead to a dense texture. Aim for a crumbly consistency by mixing just until combined.
- Skipping the cooling time: Serving immediately can result in a runny filling. Let the crisp sit for about 10 minutes before serving to allow it to set.
- Using old or frozen rhubarb without thawing: If using frozen rhubarb, thaw and drain excess moisture. This prevents your crisp from becoming soggy.
