Ingredients

2 lb rhubarb (frozen, cut into 1-inch pieces)
1/2 tsp cinnamon
3/4 cup sugar
1/4 cup cornstarch

For the topping:

1/2 tsp cinnamon
1 stick unsalted butter (cold, cubed)
1/2 cup all-purpose flour
1 cup rolled oats
1/2 cup sugar
1 pinch salt

Step-by-Step Instructions

Preparing the Ingredients

Preheat your oven to 400°F and lightly butter a 2-quart casserole dish. Then, combine the rhubarb, sugar, cinnamon, and cornstarch in a large bowl and mix until evenly coated. Spread this mixture evenly into the prepared dish. In another bowl, mix oats, flour, sugar, cinnamon, and salt. Cut in the cold butter until the mixture forms crumbly pieces.

Cooking Instructions

Sprinkle the crumb topping evenly over the rhubarb mixture, then place the dish in the oven. Bake for about 35–40 minutes until the topping turns golden and the filling bubbles around the edges. After baking, remove the dish and let it cool for at least 10 minutes before serving.

Tips for Perfect Results

Common Mistakes to Avoid

Avoid skipping the cornstarch because it thickens the filling properly. Also, do not overmix the topping, or it will lose its crumb texture. Using warm butter instead of cold butter can prevent a crisp topping, so always keep it chilled.

Pro Tips for Better Flavor

Add a pinch of extra cinnamon for deeper warmth, or mix a little brown sugar into the topping for richer taste. If the rhubarb tastes too tart, slightly increase the sugar to balance flavors without overpowering the fruit.

Serving and Storage

How to Serve

Serve Traditional Rhubarb Crisp warm for the best texture and flavor. It pairs well with vanilla ice cream or whipped cream, which adds a creamy contrast to the tart filling.

How to Store Leftovers

Store leftovers in an airtight container in the refrigerator for up to five days. For longer storage, freeze the crisp for up to three months. Reheat in a 350°F oven for 15–20 minutes, or microwave for a quicker option.

Conclusion

Traditional Rhubarb Crisp delivers a simple yet satisfying dessert that anyone can make at home. With its crisp topping and tangy filling, this recipe offers a comforting treat that works year-round. Try it once, and it will likely become a regular part of your baking routine.
