how to make rhubarb crisp

Perfect for a spring or early summer, this strawberry rhubarb crisp is one of the easiest and best desserts I know. It’s wonderful served warm from the oven with a scoop of vanilla ice cream. But if you happen to have leftovers, they’re delicious with your morning coffee, too. Heads up: while fruit desserts like this one tend to be flexible, be sure to keep the ratio of rhubarb to strawberries the same. As tempting as it might be to add extra strawberries, doing so can lead to a too-juicy “fruit soup” situation, since strawberries release a ton of juice. For more seasonal fruit crisp variations, see my summer peach crisp and autumn apple crisp.

What You’ll Need To Make Strawberry Rhubarb Crisp

Crisp ingredients including corn starch, vanilla, and oats.

If you’ve never cooked with rhubarb, now is the time to start! Technically, it’s a vegetable but you treat it like fruit. It’s very tart but when you add a little sugar and cook it down, it becomes deliciously sweet, like berries. To prepare it for this recipe, trim the leaves (they should not be eaten) and rough ends and wash the stalks, then cut them into 1/2-inch pieces.

Step-by-Step Instructions

Bowl of fruit with sugar and cornstarch.

Quarter the strawberries and combine them with the rhubarb, sugar, cornstarch and vanilla. Stir until the fruit is evenly coated with the sugar mixture, and the sugar mixture is no longer white.

Servings: 6-8
Prep Time: 20 Minutes
Cook Time: 50 Minutes
Total Time: 1 Hour 10 Minutes

Ingredients

For the Filling

  • 1 pound rhubarb stalks, trimmed and sliced ½-inch thick (about 4 cups)
  • ½ pound strawberries, hulled and quartered (about 2 cups)
  • ½ cup granulated sugar
  • 1½ tablespoons cornstarch
  • 1 teaspoon vanilla extract

For the Topping

  • ¾ cup all-purpose flour, spooned into measuring cup and leveled-off with a knife
  • ½ cup packed light brown sugar
  • 2 tablespoons granulated sugar
  • ¼ teaspoon salt
  • 6 tablespoons unsalted butter, cut into ½-inch cubes
  • ¾ cup old fashioned rolled oats
  • ½ cup chopped pecans
  • Lightly sweetened whipped cream or vanilla ice cream, for serving (optional)

Instructions

  1. Preheat the oven to 350°F.

For the Filling

  1. In a large bowl, combine the rhubarb, strawberries, sugar, cornstarch, and vanilla. Stir until the fruit is evenly coated with the sugar mixture, and the sugar mixture is no longer white.
  2. Transfer the fruit mixture to a 2-quart or 8-inch baking dish (no need to butter it) and set aside while you prepare the topping.

For the Topping

  1. In the bowl of a food processor, combine the flour, brown sugar, granulated sugar and salt. Process until well combined, about 30 seconds. Add the cold butter and pulse until the mixture resembles coarse crumbs, with a few pea-sized clumps of butter within. Transfer to a medium bowl and stir in the oats and chopped pecans.
  2. Spoon the topping evenly over the fruit without packing down. Bake for 45-55 minutes, until the fruit is bubbling around the edges and the topping is golden brown. Cool for 20 minutes before serving. Spoon into shallow bowls and serve with vanilla ice cream.
  3. Note: If your baking dish is shallow, place it on top of a foil-lined sheet pan to catch any spills that might bubble over the edges.
  4. Note: Don't be tempted to increase the strawberries in the recipe, or you'll end up with fruit soup (they release a lot of juice).
  5. Freezer-Friendly Instructions: The crisp can be frozen tightly covered for up to 3 months. Before serving, reheat it, uncovered, in a 300°F oven until heated through and crisp on top.

  • This was the most delicious strawberry rhubarb crisp (or dessert for that matter) that I’ve ever had. I have made it twice now. The first time I didn’t have enough rhubarb so against the author’s advice, I added more strawberries. Having done so, I omitted the cornstarch and used 3 TBLS of tapioca to soak up the juice.
    The next time I made it, I used a bigger pan which I didn’t like as much. It made the dessert a little thin. It was still delicious though. I think an 8×8 is a good size for this dessert.

  • This recipe sounds wonderful, but there’s no instructions on how much flour to use or any of the ingredients that are needed. Could you please share the amounts please.

    • Hi Sharon, It sounds like you are just looking at the portion of the page that has the pictures with some instructions underneath. If you scroll down a bit to under the pictures, you’ll find the full recipe. Alternatively, at the very top of the page, to the right of the recipe name, you’ll see an orange/red button that says Jump to Recipe – if you click on that, it will take you directly to the recipe. Hope that clarifies!

    • I made this for a friend and he said it was GREAT!

  • Can not stop making this. Everyone loves it and keeps asking for more. Huge bonus is it’s so EASY to make. Thanks for a great recipe.

  • Loved this recipe! Just made it tonight and partner and I devoured most of it in one go. I did not measure the fruit, I just used up what I had as it was about to turn; but it filled the dish nicely so was probably close to accurate. I had no brown sugar so just used all white and it still turned out amazing! This one’s a keeper for sure.

  • I have made this recipe many times, always with positive results! I alter slightly to make it gluten free (using GF flour and GF rolled oats) and dairy free (using margarine instead of butter). I also cut down on the sugar as we like a tart crisp. In fact I just made it tonight for dessert after making your beef stew with carrots and potatoes for dinner! Both are go-to favourites in my house! Thanks for these (now) family traditions!

  • how many cups is 1 pound of rhubarb? How many cups is 1/2 pound strawberries?

    • Hi Jan, When you slice the rhubarb, the volume should fill approximately 4 (measuring) cups. The sliced strawberries would be the equivalent of about 1-3/4 cups. Hope that helps and you enjoy!

  • This was by far and away, the best crisp I’ve ever had. However, I did add more strawberries (I just HAD to). To compensate, I added 3 TBLS of Tapioca and omitted the corn starch.

  • Hi Jenn,
    Is it possible to substitute steel cut oats instead of rolled oats? Will it affect the taste/texture? And would you suggest altering the bake time? Thanks so much, hope you and your family have a wonderful Fourth of July!

    • Happy 4th to you! I wouldn’t recommend steel cut oats here — sorry!

  • Too sweet. W

    • Hi!
      Would I be able to substitute walnuts for pecans?
