It is crunchy thanks to the nuts, flavorful because of the oats and a bit tart and sweet, thanks to the rhubarb.

Rhubarb is and easy plant to grow. It like moist, well drained soils. Make sure you leave at least 6 leaf stalks when you pick your rhubarb. If you don’t grow your own rhubarb, it can be found at farm stands from April through the end of June, depending on where you live.

Feel free to add strawberries if you’d like a strawberry rhubarb crisp.

Only eat the leaf stalks!

Did you know that the only part of the rhubarb plant that is edible is the thick leaf stalks, technically known as the petiole? The leaves and roots are actually quite poisonous. Only use the red stalks.

Is rhubarb healthy?

Rhubarb has many health benefits. It is high in calcium and fiber, contains significant quantities of vitamins K and C and is also high in iron and manganese!

The crisp itself is fairly healthy, due to the fiber from the oats and nuts, as well.

What you need for filling

  • rhubarb
  • raw sugar
  • eggs
  • cornstarch

What you need for crisp topping

  • gluten-free oats
  • chopped nuts, pecans, walnuts, almonds, hazelnuts, etc.
  • cinnamon
  • salt
  • coconut oil – you can substitute vegan butter if you don’t have coconut oil.
  • raw sugar – brown sugar is a great substitute for the raw sugar

How to make it

  1. Beat eggs.
  2. Chop rhubarb into 1/2 inch pieces. Add the rest of ingredients to bowl.
  3. Mix well.
  4. Chop nuts.
  5. Add all ingredients for topping to another bowl.
  6. Stir to mix well.
  7. Place the filling mixture in bottom of oven-proof baking dish.
  8. Sprinkle with the topping.

Bake for 30-40 minutes, at 350 degrees F, until the topping is golden brown and the filling is hot, bubbly and the rhubarb is tender, when pierced with fork.

Pro tips for success

This recipe is incredibly easy and forgiving. But here are a few tips.

  • Buy fresh, organic rhubarb. Although rhubarb rarely requires spraying, there are a few insects that farmers may be tempted to spray for. These chemicals will be stored in the stalks (petiole).
  • Make sure you source gluten free oats. All oats are not certified gluten free.
  • Quantities are not crucial for this recipe. Adding more or less of any ingredient will not ruin the outcome. It will just change the flavor slightly.
  • This recipe is on the tart side, so if it’s not sweet enough for you, just add more sugar.
  • Serve with a scoop of vanilla ice cream.

Believe it or not, I actually preferred this crisp to my rhubarb pie, because of the crunchiness the oats and nuts add. It really is tasty!

I so wanted to make a savory dish with rhubarb this year. But alas, I ran out of rhubarb! The only bad thing is that now I have to wait until next year to give a savory dish a go!

I guess that’s why seasonal treats tastes so good to us. If we could eat them any day of the year, they wouldn’t be as special, would they?

General Baking Tips:
Always measure dry ingredients with a dry measuring cup. Measure with dry measuring cups or weigh dry ingredients.
Always measure liquid ingredients with liquid measuring cup
Never break eggs directly into recipe ingredients. Break eggs into a separate bowl, in case you get any shells, so that you can pull them out.
Make sure that you know what temperature your oven is set at. Buy an oven thermometer and check oven temperature regularly.
Always check baked goods, like cakes or quick breads with cake tester, placed in center. If the tester comes out clean, it’s done.

    I love finding new recipes to use up the rhubarb that grows in my garden. This recipe is easy to make and a delicious dessert.

  5. 5 stars
    I have to admit that I have never cooked with rhubarb and have really only eaten it a few times. I think it’s just not widely available in our area, though I’m sure I can find it when it’s in season. This crisp looks fabulous and I love sweet-tartness quality. Can’t wait to try.

  6. I just was gifted some rhubarb and will make this – looks delish. Assuming it’s one cup of any of the choices of nuts, not necessarily a cup of each, correct? Thank you!

    1. Yes, I am sorry, Meri! I will change the wording to make that more clear! I hope you enjoy it! Let me know what you think!

        Sorry for my delay, but was revisiting this recipe as I want to try this with strawberries. I will say this is truly one of my favorite desserts I’ve every made (and I make a lot). So delicious!!

        1. I love it! Strawberries would be a great addition too! Add a bit more sweetness! Maybe cut back on the sugar a bit? Just a thought. Thanks for letting me know that you liked it Meri! I really appreciate that!

          1. Hi Beth – I didn’t see your reply until after I made this was strawberries. It was good too, but you’re right, maybe cutting back on the sugar would have been a good idea. Still delicious and it’s gone:). I do think I like it a little bit better with the Rhubarb, but it’s very close.

          2. Oh, I’m sorry, was I late answering? I love the rhubarb because it’s so tart and I’m all about tart desserts! Thanks for the update Meri! If it’s gone already, it couldn’t have been too bad! 🙂

    This looks wonderful! I’m sure your mom loved it! Too bad rhubarb isn’t more available throughout the year!

    1. I agree, Caroline! I guess, it wouldn’t be quite as special if it were, but I would be willing to have it all year and test out that theory! Thank you for your Comment!

  10. Wow. This looks really delicious – and that crust seems pretty versatile. I have everything it takes to make this – except the Rhubarb. I definitely want to try it. Pinning it.

    Rhubarb reminds me of my childhood when I was able to pick it at my gramma’s garden and eat it straight 🙂 I loved it. It’s even better in a pie or crisp form. I love your gluten free version!
