This Will Be a Go-To Dessert Because…

  • Rhubarb crisp is easy to make.
  • It’s the perfect balance between sweet and tart.
  • Prep it days in advance and bake before serving.

How to Prepare Rhubarb for Crisp

  1. Pull the rhubarb from the plant (rather than cutting). Remove the leaves and discard them. Rinse any dirt or debris from the stalk.
  2. You do not have to peel rhubarb; however, if the stalk is quite thick, peeling the tougher exterior is a good idea.
  3. The fresh rhubarb can be chopped and refrigerated or frozen for future recipes.

Important Note

You can eat the green/red stalk of a rhubarb plant. However, the leaves are poisonous to eat (for humans and animals alike), so discard them .

How to Make Rhubarb Crisp

  1. Prepare the rhubarb and toss with flour, sugar, and cinnamon.
  2. Prepare the crisp topping.
  3. Sprinkle the topping over fruit layer and bake until golden brown.

This recipe serves 4 but can easily be doubled for a 9×13 pan.

Holly’s Tips

  • Some stalks of rhubarb will produce a lot of juice; be sure to let it rest to thicken.
  • If using frozen rhubarb, increase the flour to 4 tablespoons in the fruit mix and increase the baking time by 10 to 15 minutes
  • Other fruits can be added to change the flavor, apples, raspberries, and strawberries are favorites.
  • Prepare large batches of the oatmeal topping and store in the freezer. To make crisp, simply sprinkle over fruit and bake.

Storing and Freezing Rhubarb Crisp

As with other desserts like pie, crispy can sit at room temperature overnight. If you are storing it for several days, refrigerate leftovers.

To Freeze Rhubarb: I love to make rhubarb crisp and you can freeze rhubarb crisp to enjoy in the off season.

  1. Super easy recipe to prepare! Crisp is currently in the oven… Will leave a further review in about 30 mins.

    (40 mins later) The rhubarb crisp turned out perfectly done and it tasted amazing! Next time, I will try using corn starch to see what the difference is like.5 stars

  2. What are the directions for freezing and reheating the crisp? I would like to give it as part of my church’s “casserole brigade.” My apologies if I missed the directions.

    1. I would recommend you let it thaw for a few hours or overnight before popping in the oven. If thawed, the cooking time should remain the same.

  3. I made this with rhubarb harvested fresh from our garden this summer (2023). I am pretty sure I added extra cinnamon and maybe used cornstarch in stead of the flour with the fruit. It was so delicious. I just wished I had saved the recipe because it took two days of looking online to find it again. Thankfully I froze extra sticks of washed rhubarb, as my tastebuds are craving some Rhubarb Crisp (gluten free of course) . I also found your Rhubarb Juice recipe which I typed out and translated into Polish (with the help of the internet) for an elderly friend of mine, Mary, 86. She said the juice was so delicious! It warmed my heart to hear how she went on and on about the juice. Maybe next summer I will make some too. Much thanks. PS: I have now typed the Rhubarb Crisp recipe for myself with the link to your website so I can find my way back here another time.5 stars

      1. Hi Ruth, we just add the frozen rhubarb directly. If you feel yours is very watery you can always add a little extra flour to help it thicken.

  4. Husband gave rave review on this crisp, stating I need to put it on my favourites list. I usually try to follow a recipe as written in my first try. This time I ran into some confusion on my part. I previously froze 8 cups of rhubarb in bags. I defrosted two bags before I read this recipe that says not to defrost. The defrosted bags yielded 4 cups each – so do i add one of the bags which now measures 4 cups but started out as 8 cups? I ended up draining the two bags of defrosted rhubarb, combining and making 1.5 x the recipe but with 8 cups of defrosted rhubarb. I suspect this equals much more rhubarb than called for but I was winging it, hoping for the best. I added coconut, walnuts and a pinch of salt to the topping and use margarine as the fat. I was generous with the cinnamon in both the fruit and the topping. Cooked in disposable 8×6 pans and got three full crisps that I give a 5 star score. I know I can make this keto by exchanging the sugars, fats to keto approved ingredients – next time! Thanks for the easy and delicious recipe.5 stars

    1. That all sounds delicious, Judith. Since we recommend adding the rhubarb straight from frozen I would use your pre measured amounts or measure it frozen next time. But I am glad you enjoyed it. Especially since you have so much!

  5. This recipe turned out perfectly. I only had 4 cups of rhubarb so used 1/2 cup of sugar. The only thing I added was a bit of grated lemon and it was delicious.5 stars

  6. Love your recipe for rhubarb and apples crisps . I like a little more cinnamon so added 1/2 tsp to both topping and filling. But great mix for toppings.
