Rhubarb Crisp Ingredients
![Rhubarb Crisp raw ingredients that are labeled](https://spaceshipsandlaserbeams.com/wp-content/uploads/2022/04/Rhubarb-Crisp-ingredients.jpg)
NOTE: It is essential to ensure that you do not eat the leaves, root or bottom stem area of rhubarb, as it will make you sick.
You’ll need:
For the Filling
- 4 cups of rhubarb, cut into bite-size pieces
- 1 cup granulated sugar
- 1 teaspoon vanilla extract
- 2 tablespoons lemon juice (or water)
- 2 tablespoons cornstarch
For the Crisp Topping
- ⅔ cup all-purpose flour
- ⅔ cup rolled oats
- ⅔ cup light brown sugar, packed
- ½ teaspoon ground cinnamon
- Pinch of salt
- ½ cup unsalted butter, cold
PRO TIP:
Rhubarb is tart and just slightly sweet, but the granulated sugar is enough to create a perfect balance in this dessert.
SUBSTITUTIONS AND ADDITIONS
OLD-FASHIONED OATS: These are also known as rolled oats. It’s fine to use quick-cooking oats for the crunchy topping instead if that’s what you have in the cupboard.
BUTTER: To make this easy rhubarb crisp suitable for vegans, you could switch the butter to dairy-free margarine.

You can throw together the topping the night before and store it in the fridge until you are ready to assemble this fruit crisp.
How to Make This Rhubarb Crisp Recipe
STEP ONE: Preheat the oven to 350°F. Spray a 9×13-inch baking dish with non-stick cooking spray.

PRO TIP:
Rhubarb does need to be peeled or prepared beyond rinsing and cutting off the ends of the stalks. Do not consume any rhubarb leaves as they are toxic.
STEP THREE: Stir the cornstarch into the lemon juice until dissolved and pour it over the fruit mixture. Toss to combine.

Comments
Doris says
Can I use frozen rhubarb if I want to make this during the winter when fresh isn’t available?
Layne Kangas says
Hi, Doris – I think it should work but we haven’t tested that personally. I’m not sure if it would be a little more runny with frozen instead of fresh? Let me know if you try it, enjoy!
