Simple Rhubarb Crisp recipe topped with whipped cream.

Hi Bold Bakers!

Rhubarb, the highly sought after tart vegetable of summer, is often paired with strawberry to balance out the fruit’s sweetness — but a rhubarb crisp on its own (with a little whipped cream) is absolutely incredible and perfect for anyone who doesn’t have a strictly sweet tooth.

My Rhubarb Crisp recipe is a simple recipe to make, but its flavors instantly transport me back to my childhood in Ireland. My mum made a lot of crisps when I was growing up, and this tangy rhubarb has become one of my summertime favorites. 

In this homemade rhubarb crisp recipe, the rhubarb and sugar bake down to become almost a jam, while the brown sugar, butter, and cinnamon topping become an irresistible crunchy texture. It really is a perfect combination, and I’m sure this recipe will become one of your favorite summer desserts! 

What Is Rhubarb Crisp?

Rhubarb is a fairly sour vegetable, not something you’d typically think to include in a dessert. However, its tartness is perfect when it is paired with a little sugar. When baked together, you’re left with a slightly sweet, slightly tart, saucy fruit-like filling. Top that with your crisp, which is made with brown sugar, flour, and butter, and you have a highly addictive dessert.

How To Make Rhubarb Crisp

This rhubarb crisp recipe is perfect for a crowd, or a smaller gathering of just two! Feel free to double or halve the recipe as you need! Here is a quick step-by-step guide (and don’t forget to get the full recipe with measurements, on the page down below):

  1. In your baking dish, toss the rhubarb, flour, sugar, and cinnamon together and set aside.
  2. In a separate bowl, assemble your crumble topping. Combine brown sugar, sugar, flour, and cinnamon. Cut in the butter until the mixture resembles large crumbs. 
  3. Sprinkle the crumble topping over the filling, and don’t be afraid to pile it high! It will fall as it bakes.
  4. Bake in a 375°F (190°C) preheated oven for about 60 minutes, or until the topping is golden brown and the filling is bubbling. 
  5. Allow the rhubarb crisp to cool for 15 minutes before serving. Serve warm with whipped cream or vanilla ice cream! 

Gemma’s Pro Chef Tips for Making Rhubarb Crisp

  • For the best topping to filling ratio, bake in a shallow dish!
  • Crisps are best the day they are made, but it will become more and more delicious the longer it sits out of the oven! Have patience when you take it out, the fruit will become even more concentrated and delicious, and it will be easier to serve when it has slightly cooled. 
  • Defrosted frozen rhubarb will work just as well as fresh.
  • Feel free to mix up the fruit in this recipe! Add a little apple, or make it a strawberry and rhubarb crisp.
