Rhubarb Crisp is family favorite that takes just minutes to prep!
This crisp recipe is a perfect balance between sweet and tart with a saucy rhubarb filling and a buttery oat crisp topping.
Rhubarb Crisp Is A Favorite Because…
- It’s super easy to make!
- This rhubarb crisp is the perfect balance between sweet and tart.
- It can be prepared ahead of time (up to 3 days) and baked before serving.
- Rhubarb crisp reheats well for dessert (or breakfast) throughout the week.
How to Prepare Rhubarb for Crisp
You can use frozen or fresh rhubarb for this recipe. If using frozen rhubarb, add 1 tablespoon of extra flour to the filling and do not thaw it first.
- When picking rhubarb, pull the stalk from the plant close to the root. Cut off the leaves and discard them.
- You do not have to peel rhubarb; however, if the stalk is quite thick, you can peel the tougher exterior if you’d like. I personally don’t usually bother peeling it.
You can eat the green stalk however the leaves are poisonous to eat so discard them (for humans and animals alike).
How to Make Rhubarb Crisp
- Chop the rhubarb and toss it with a bit of flour, sugar, and cinnamon (recipe below).
- Prepare the oat topping.
- Sprinkle the topping over fruit layer and bake until golden brown.
Short on Rhubarb?
If you don’t have enough rhubarb, you can add chopped apples or sliced strawberries (see notes).
Storage and Freezing
As with other desserts like pie, this rhubarb crisp is fine to sit at room temperature overnight after baking. If storing for several days, refrigerate any leftovers.

I made this for a couple friends coming over. One of them said they didn’t even like Rab and they absolutely loved this recipe. I couldn’t find the exact recipe but today you sent this recipe to me because I liked it. Thank you so much.
What size pan do you use for the rhubarb crisp?
We bake it in a 9×9 or 2-quart baking dish.
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.
Delicious and so easy.
I used 5 cups rhubarb and 1 cup of strawberries. DELICIOUS!
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.
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.
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.
So happy you are enjoying this recipe so much, Joanne!
Do i need to add more flour if using frozen rhubarb? Thanks
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.
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.
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!
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.
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.
This was a very big hit with my family. Recipe was super easy.
