This rhubarb crisp recipe features tart, jammy rhubarb topped with a buttery oat crumble. It’s SO easy and delicious—the perfect spring dessert!

Step aside, strawberry rhubarb pie! This rhubarb crisp recipe is my favorite spring dessert.

I love it because it’s so easy (HUGE bonus points for not requiring pie crust), but it’s still completely delicious. A layer of fresh rhubarb bakes to jammy, sweet-tart perfection, and a brown sugar and oat crumble crisps up beautifully on top. I’m personally incapable of eating it without a scoop of vanilla ice cream, but hey, you do you.

I’ve been making this rhubarb crisp recipe for years now. In fact, I first planned to share it three years ago, right around the time our son was born. If you’re a parent, I’m sure you’re not surprised that our whole blog schedule kinda went out the window for a few weeks then, long enough for rhubarb season to come and go. But I’m so glad that this rhubarb crisp recipe is finally getting its moment. It’s such a wonderful spring treat, and I can’t wait for you to try it. Please, enjoy!

Rhubarb Crisp Recipe Ingredients

Here’s what you’ll need to make this rhubarb crisp recipe:

• Rhubarb, of course! Two pounds of fresh or frozen rhubarb stalks will do the trick. If you’re using frozen rhubarb, no need to thaw it before baking.
• White sugar – For sweetening the tart rhubarb.
• Cornstarch – It makes the rhubarb juices thick and glossy.
• Orange juice and zest – They add citrusy fragrance and freshness to the tangy filling.
• Almond flour and walnuts – They add nutty crunch to the oat topping.
• Brown sugar – It sweetens the topping. Dark and light brown sugar both work great!
• Whole rolled oats – They become crisp and golden brown in the oven, giving the topping amazing texture and toasty flavor.
• Cinnamon – For warm, cozy depth of flavor.
• Coconut oil – Butter works too! It adds rich flavor to the topping and helps it get nice and crisp.
• And sea salt – To make all the flavors pop!

How to Make Rhubarb Crisp

This rhubarb crisp recipe couldn’t be simpler to make! Here’s how it goes:

First, prepare the rhubarb. If yours has leaves attached, trim them off and discard them. You’ll just need the stalks for this recipe.

Wash them well. Then, peel off any tough, stringy outer skin. Cut the rhubarb into 1/2-inch pieces.

Next, make the rhubarb filling. Toss the chopped rhubarb with the white sugar, cornstarch, and orange juice and zest.

Then, make the crumble topping. In a medium bowl, stir together the almond flour, brown sugar, oats, walnuts, cinnamon, and salt. Add the coconut oil (make sure it’s firm!), and use your hands to work it into the oat mixture until it crumbles. If the mixture feels dry, add water, 1/4 teaspoon at a time, until it starts to hold together when pinched.

Assemble the rhubarb crisp. Transfer the rhubarb mixture to a greased 8×8-inch baking dish, and spread it in an even layer. Sprinkle the oat crumble on top.

And bake! Bake in a 375°F oven until the crisp topping is golden brown and the rhubarb is soft and bubbling, 25 to 30 minutes. If the topping is browning too much before the rhubarb is tender, cover the crisp with foil and continue to bake until the rhubarb is soft.

Let cool for 5 minutes before serving with vanilla ice cream.

How to Store Rhubarb Crisp

If your family is anything like ours, you won’t have much (ok, any) rhubarb crisp left after the first night. But if you do happen to have leftovers, you can store them, covered, at room temperature for up to 2 days or for up to 4 days in the refrigerator.

Tip: Leftover rhubarb crisp with a scoop of Greek yogurt makes a mean breakfast. 🙂
