Is rhubarb a fruit or a vegetable?

This is a common question! Rhubarb is actually a vegetable, but because it is often used in desserts, people often assume it is a fruit.

Do you have to peel rhubarb?

No. We don’t take the time to peel rhubarb. Although it doesn’t have a “peel” like other fruits do, it does have strings similar to celery. You don’t have to remove the strings before baking (although you can if you want to).

If strings happen to loosen and hang while I’m chopped, I’ll pull those off and discard them. Otherwise I leave them on.

How to Make Rhubarb Crisp

We bake our rhubarb crisp in a 9″ round pie plate. Make sure it is a deep dish pie plate so it holds all of the rhubarb and crumble. If you don’t have a pie plate you can also use an 8×8 baking pan.

• In a medium bowl, mix together the flour, brown sugar, cinnamon, oatmeal and butter until crumbly.
• Place half of the oatmeal crumble mixture into the bottom of the pie plate. Press down lightly to cover the bottom.
• Arrange the sliced rhubarb on top of the crumble.

Prepare the sugar syrup:

• In a medium saucepan, combine the sugar, cornstarch, water and vanilla. Cook over low heat until the syrup is clear.
• Pour the syrup over the rhubarb.

• Sprinkle the remaining crumb topping evenly over the rhubarb.
• Bake for 45 minutes until the rhubarb is tender.

How long does rhubarb crisp last?

We find that rhubarb crisp is best eaten within 1-2 days of baking. Sometimes the juices will make the crisp not be so…well…crisp!

If you don’t mind the crumble softening, it will last 3-4 days.

Does rhubarb crisp need to be refrigerated?

Because of the freshness of this recipe, you’ll want to cover any leftover crisp and refrigerate it. If you don’t like to eat it cold you can warm it in the microwave or even in the oven.
