This easy rhubarb crisp recipe will become your go-to when you need a quick and easy — dare I say fail-proof? — late spring or summer dessert. The tartness of the rhubarb is set off perfectly with the lightly sweet oat topping, and it’s even reasonably healthy. Rhubarb is a vegetable, after all!
This recipe goes easy on the sweetener so you can enjoy an extra helping without guilt. And since you can probably get most of your rhubarb for free, it’s an inexpensive but crowd-pleasing dish for your next summer gathering.
Everyone will LOVE this Easy Rhubarb Crisp Recipe!
Another rhubarb season is upon us — woooohooo!
Yes, for real, I get SUPER excited about rhubarb season! I am, admittedly, a card-carrying garden geek who lives in a climate not really suited to garden geeks, card-carrying or otherwise.
Winter is seriously 6 months long here, people. The growing season is May-October and that’s it.
And rhubarb is one of the first things to poke out of the ground around here, um, in mid-APRIL if we’re lucky enough that our five feet of snow has melted.
Arugula? Not so much. (Though I do like to add foraged greens to my anti-inflammatory smoothie.)
Any of you who also have a bit of a sour tooth are probably also wild about rhubarb, that tart vegetable we treat as a fruit.
Fruit leather made with rhubarb is the big draw of rhubarb in this household, but there’s usually plenty left to make this easy rhubarb crisp recipe a few times.

Celebrate Rhubarb with this Easy Rhubarb Crisp Recipe!
Since we don’t often have dessert, this rhubarb crisp usually results from an invitation to a potluck, which we tend to have lots of in our precious few months of warm weather. In addition to being a cinch to throw together, because the primary ingredient is something I grow in my yard, a huge rhubarb crisp pretty cost-effective way to contribute to a party for 30 people.
Rhubarb is such a healthy ingredient, I hate to see it sullied by lots of not-so-healthy sugar and white flour, so we go easy on sugar and use whole grains for the topping.
–> Here’s the surprising truth about how much sugar per day experts recommend.
While rhubarb pie might be one of the better-known things to do with rhubarb, I’ve never been a big fan of pie crust and oversweetened filling, and you probably know that pie is waaaaaaay too complicated for this simple cook.
So let’s keep it healthy-ish and super-simple, just the way we like it.
This easy rhubarb crisp recipe takes less than 10 minutes to prep and in my opinion tastes so much better than any pie. No crust means more perfectly tart-sweet rhubarb balanced by the subtle sweetness of the oat topping.
Crisp, Crumble, or Cobbler?
As far as I can tell, whether you call this a rhubarb crisp or a rhubarb crumble is mostly about where you live, but technically a crisp contains oats and a crumble uses only flour. In my opinion, crisp wins, making a chewier, whole-grain topping.
Cobbler is another beast altogether. It has a biscuit topping, and I much prefer to keep this a fruit-focused dessert than a bread-focused one. Apparently there are also versions of this dessert called buckle and Betty, but that’s way above my pay grade, which pretty much ends at crisp. This post will explain those to you if you’re curious.
This easy rhubarb crisp is the perfect summer dessert. As someone who doesn’t make desserts often, it’s also my go-to for an easy dish to bring to summer picnics and potlucks. It’s always popular, and the pan empties out pretty quickly. You might want to make two if you’re feeding a crowd!
You could absolutely add a scoop of ice cream or whipped cream, but I find that completely unnecessary. I want pure, unadulterated, rhubarb crisp goodness! Possibly several servings of it. And leftovers the next day!
This easy rhubarb crisp is
- The perfect blend of tart and sweet
- Covered with crunchy, sweet oat topping
- Quick to make — just a few minutes to throw together
- Simple enough for beginner cooks to get right
- Has a serving of vegetables — woot!
- Only lightly sweetened, so you don’t blow through your sugar budget for the day!
- A crowd-pleaser. Watch how fast it disappears at your next potluck!

Sourcing Your Rhubarb for Rhubarb Crisp
You’ll find rhubarb at grocery stores for a couple months starting in May. But rhubarb is so easy to grow and so nice to have huge quantities of, I highly recommend planting your own. Plus, if you keep your plants picked, you can enjoy a much longer rhubarb season.
Here’s how to grow rhubarb, so you can enjoy your own bountiful supply of this awesome veggie!
You can usually find someone with a rhubarb plant who will give you a free division to get you started. Here’s what to know about scoring free plants for your garden!
If you consider yourself a brown thumb, you’ll be happy to know that rhubarb is absurdly tough and can tolerate a fair amount of neglect. It’s also one of the vegetables that grow in shade if your yard doesn’t get much sun. You’ll get a bit less rhubarb, but some rhubarb is way better than none, right?
If you’re not up for growing your own, I’ve found that most people who grow rhubarb in their yard usually have plenty to spare. Ask around, or post an “ISO” on Freecycle or your neighborhood networks.
**Don’t forget that rhubarb leaves are poisonous — we only eat the stalks.**
Rhubarb Crisp Ingredients
Whenever possible, choose organic ingredients, preferably not packaged in plastic.
I pick up my flour, oats, cinnamon, and nuts using mason jars at my local food co-op. You can do the same to start heading your shopping toward zero waste.
You’ll save money as well! (My organic oats and flour cost $1.69/lb, and I can fill up my cinnamon jar for about 50 cents, waaaaay less than buying packaged versions.)
