Rhubarb Crisp is not too sweet yet hits the spot on a warm evening when you want something crunchy and a little fruity with some vanilla bean ice cream.

I love that this recipe uses no other fruit but rhubarb, and that really helps to highlight all that rhubarb goodness. You are going to love this recipe. (And if that isn’t quite what you’re in the mood for, maybe you’ll love my Strawberry Rhubarb Crisp or Apple Crumble.)

Recipe Ingredients

For the fruit part:

  • Chopped rhubarb: Of course, this is the star of the show! You can use any type you have available to you (red or green) and frozen rhubarb works great too.
  • White Sugar
  • Cornstarch

And for the topping, you’ll need:

  • Brown sugar
  • White sugar
  • Flour: Flour holds everything together and thickens the topping like a crunchy crust.
  • Oats: The oats add a nice textured element.
  • Pecans: Pecans are optional, or you can use another favorite nut like walnuts.
  • Vanilla
  • Melted butter

How to Make Rhubarb Crisp

Step #1. Preheat oven to 375 degrees F. Spray 8×8-inch baking dish or 4-6 individual ramekins with cooking spray.

Step #2. Combine chopped rhubarb, sugar, and cornstarch, and stir to combine. Combine the sugars, flour, oats, and pecans in another bowl; stir with fork to combine. Add vanilla and melted butter; stir until no dry powder is left.

Step #4. Let the crisp cool for 5 minutes before serving hot. Top with ice cream or whipped cream, if desired.

Recipe FAQs

What is Rhubarb?

It’s one of my favorite easy go-to perennials on our farm, and I look forward to it every spring. It grows in stalks and it’s tart, like a tart cherry (which is so good in baking). And fun fact, it’s super high in vitamin C. We like to eat it raw like celery with a bit of salt on it when we aren’t turning it into our favorite rhubarb desserts.

Is Rhubarb Poisonous?

Fun fact… rhubarb leaves are poisonous. While it would take ingesting roughly 10 pounds of leaves to kill an average-size adult, small amounts will make you sick. Be sure to keep livestock and chickens out of your rhubarb patch, too — it’s not good for them either. Have no fear; the stalks are just fine.

Can I double this recipe?

Sure! Use a 9×13 pan instead of an 8×8 but it may need a few more minutes to cook if the layers are thicker.

Tips for the Best Rhubarb Crisp

  • Melt the butter: My trick to making the best crisp on the block is to melt the butter and then stir it into the oat mixture. This means that you’ll never have any dry pockets of oats and flour and it bakes up extra crispy.
  • Use any kind of rhubarb: Rhubarb comes in lots of varieties. You’ll generally see red rhubarb, but it also comes in green. All of them taste pretty similar, so just use what you can find.
  • Search for rhubarb in spring: New to the rhubarb scene? Look for it at the farmers marker in mid to late spring. It’s normally one of the first bits of produce you’ll find.
  • Bake in individual ramekins or an 8×8 baking dish: I love serving rhubarb crisp in individual ramekins with a scoop of ice cream on top, but you can also make this recipe in an 8×8 baking dish. Do what you have! Individual is just fun, though, right?
  • Leave out pecans or sub another nut: Not a fan of pecans? Leave them out or sub another nut. I think they are SO good in this crisp.

Serving Suggestions

This is a delicious dessert on its own, or to take it up a notch, pair with fresh whipped cream or vanilla bean ice cream!

How to Store a Crisp

Rhubarb crisp is best served the day it’s made. If you want to store any leftovers, let it cool completely, cover tightly with an airtight lid or plastic wrap, and store in the fridge for up to 4 days. Reheat in the oven at 350 degrees F. for 10 minutes.

  • Preheat your oven to 375 degrees F. Lightly spray an 8×8-inch square baking dish or individual ramekins (4 to 6 of them, depending on how big of a serving you want in each) with cooking spray. Set aside.
  • In a large bowl, combine the chopped rhubarb, sugar, and cornstarch, and stir to combine.
  • In a second medium bowl, combine the sugars, flour, oats, and pecans. Stir with a fork to combine.
  • Add the vanilla and melted butter, and stir until no dry powder is left.
  • Stir the rhubarb and sugar again and then place it in your baking dish, or divide it evenly among the ramekins. Place the crisp topping on top of the rhubarb in the dish. If you used ramekins, place them on a baking sheet and then transfer them to the hot oven, or put the baking dish straight into the oven. Cook for 18 to 24 minutes, until the crisp is lightly browned and the rhubarb is bubbling around the edges.
  • Let the crisp cool for 5 minutes before serving hot with ice cream or fresh whipped cream.


  • This crisp is best enjoyed the same day. Reheat it in a 350 F oven for 10 minutes.
  • You can use red or green rhubarb for this recipe.
  • Serve it with a scoop of vanilla ice cream or dollop of freshly whipped cream.
  • To store, let it cool completely then cover and store in the refrigerator.

    Such a spring delight! I found some fresh rhubarb at our local farmer’s market and found your crisp recipe ( We love our rhubarb without other fruits added too :-). The pecans are a delicious touch! I’ll be making this again before the season is over.

    1. Melissa says:

      So glad you liked it! I just planted 4 rhubarb plants!

    Looks great but who thinks putting ice cream on the desert while in the cooking pan is a good idea?

  4. Kim says:

    Love the little story I found when looking for a rhubarb crisp recipe this morning. Thanks for sharing! Perhaps you’ll have to draw or paint a likeness of Starnsie.

  5. Jamie says:

    I cut the sugar in half that is mixed with the rhubarb, left it a little tart just like we like it. And i have never made a crumb topping with melted butter, usually cut it in with a pastry blender. It was SO much faster and SO delicious! This is our go to crisp recipe now! Delicious hot out of the oven with vanilla bean ice cream. Thanks!

    1. Melissa says:

      I like it tart too! I made it again on Saturday and cut it by a 1/3rd and loved it! I should make a note in the recipe. So glad you liked it Jamie and thanks for commenting! It made my morning 🙂 And that melted butter will change your life… so easy!

  6. Erin @ Texanerin Baking says:

    What a nice post!

    And the fact that you added “with no other fruit” to the title cracked me up. I don’t know why – it’s totally necessary information. 🙂

    Your crisp looks gorgeous and amazingly yummy! I went on a mad hunt for rhubarb at the beginning of the week. It seems like rhubarb season is over but luckily I found one place with it! But like everyone else, I paired it with strawberry. Now I’m regretting it!

  7. Heather says:

    Rhubarb crisp naked…no strawberries. I am trying to wrap my mind around this and I think I love it!

  8. Jamie says:

    How did you know?? My husband just last night asked if I would make him a crisp with just rhubarb in it! I will be making this on Sunday, can’t wait to try it. Thanks!

  9. Tara says:

    Wahooo!! It’s gluten-free!!!

    1. Tara says:

      I should have said, I can make it gluten-free easily by replacing the flour with a gf flour 🙂 I got so excited to try it I wasn’t paying attention to what I was writing 🙂
